Electric engraving glass introduction

Engraving Glass is a form of decorative glasswork that involves engraving a glass surface or object. It is distinct from glass art in the narrow sense, which refers to molding and blowing glass, and from glass etching which uses acidic, caustic, or abrasive substances to achieve artistic effects. Some artists may combine two or more techniques. It is rotary engraving, often use in interior decoration and exterior building

International Year of Glass China is ready

What is the origin of the International Year of Glass?

For more than 60 years, the United Nations General Assembly has proclaimed the United Nations International Year to recognize international cooperation and concerted efforts in important fields and the contributions made by relevant organizations and institutions to society, such as the International Year of Astronomy (2009), the International Year of Chemistry (2011), International Year of Light and Light-Based Technologies (2015), International Year of the Periodic Table of Chemical Elements (2019), etc. The International Year of Glass in 2022 is the first time the United Nations has named a year after a single material. The initiative to establish the United Nations International Year of Glass is led by the International Glass Association and has received positive response and support from the global glass academia and industry. As far as we know, universities, research institutes, associations, museums, and glass companies from 90 countries and regions on five continents have provided more than 2,100 letters of support for the International Year of Glass initiative. Among them, the China Silicate Society took the lead in organizing Nearly 200 letters of support from relevant domestic units. On May 18, 2021, at the 66th plenary session of the 75th United Nations General Assembly, 2022 was officially approved as the United Nations International Year of Glass.

What is the significance of the establishment of the International Year of Glass by the United Nations? Glass is one of the earliest man-made materials invented by human beings. It has been used in human life for thousands of years. From Mesopotamia 4,000 years ago to the remains of ancient Egypt, there were small Unearthed glass beads. Nowadays, with the rapid improvement of the level of science and technology, it is widely used in construction, communication, transportation, life and health, new energy, aerospace, art, and other fields. It is a very important material in daily life and high-tech fields. played an important role in the history of technological inventions. For example, glass optical fibers have brought about a paradigm change and triggered a global communications revolution; the development of glass optics and optoelectronics has expanded human understanding of the universe; glass panels support solar cells and provide clean energy; glass fibers strengthen wind power generation Blades, which reduce carbon emissions; touch-sensitive glass screens bring smartphones into people’s lives; bioglass enables muscle tissue design and regeneration, and can solve hearing and dental problems; vitrification of hazardous waste improves the safety of nuclear energy Sex, etc… This transparent enabling material not only enters thousands of households and becomes an important medium for art, but also supports the development of many technologies. Its history is connected with the history of mankind. The establishment of this year of glass highlights the indispensable and important position of glass in many fields such as science and technology, economy, environment, culture, and society, and its role in addressing the challenges of a sustainable society, building an inclusive society, and achieving global economic recovery, promoting the development of emerging technologies, etc., are conducive to promoting the construction of a global glass community, serving the multilateral governance system with the United Nations as the core, and further highlighting the importance of glass to science, technology, economy and sustainable development and the importance of glass to human civilization. and artistic contributions.

What are the important activities of the United Nations International Year of Glass in China?
The Organizing Committee of the International Year of Glass has been divided into 18 regional committees according to various regions. Among them, China, Germany, and Brazil are independent regional committees, and the China Silicate Society is the leading unit of the regional committees in China. We will actively respond to the relevant resolutions of the United Nations, give strong support to the International Glass Association, and organize various activities of the International Year of Glass in China, including the 32nd China International Glass Industry Technology Exhibition, the 10th International Advanced Glass Symposium, the China Function Glass Academic Symposium and Forum on New Optoelectronic Materials, Summit Forum on Glass and Human Civilization, “One Belt, One Road” International Glass Art Exhibition, Glass Popular Science Series Activities, Glass Museum Series Activities, Glass Themed Winter Camp, etc.​​
From February 10th to 11th, the International Year of Glass officially opened at the Palais des Nations, the European headquarters of the United Nations in Geneva, Switzerland. At present, we plan to hold the launching ceremony of the United Nations International Year of Glass in China and the “Glass and Human Civilization” summit forum in Beijing in April and announce the selected propaganda slogan. The 32nd China International Glass Industry Technology Exhibition (referred to as China Glass Exhibition) to be held in Shanghai this year is one of the important events of the United Nations International Year of Glass (originally scheduled to be held from April 13 to 16, due to the epidemic prevention and control in Shanghai. The same heavyweight international events include the “National Glass Day” event in the United States, the theme event “From Pharaoh to High-Tech Glass” in Egypt, the 26th International Glass Conference in Germany, and the closing of the International Year of Glass in Japan at the end of the year. formula, etc.


China Glass Exhibition
This year’s China Glass Exhibition is still sponsored by the China Silicate Society and undertaken by Beijing China Silicon Exhibition Co., Ltd. The exhibition area planning will be basically the same as the previous one: Hall E1 is the international exhibition area, which brings together German and Italian national pavilions and many global glass industries. Mainstream brands, Hall E2 is for original film manufacturers and large-scale comprehensive glass manufacturers, Halls E3 to E6 are for deep processing equipment manufacturers, Hall E7 is a non-equipment exhibition area, and a special area for art glass and daily-use glass is set up.”Popular science” is also a focus of the International Year of Glass in China. In addition to planning to set up a special area for popular science at the China Glass Exhibition, we will also organize “Science and Technology Activity Week” and “National Science Popularization Day” in May, June, and September. , for middle school students and college students, adopt various forms to publicize glass science; in July and August, a series of activities for primary and middle school students to enter the glass museum and themed cultural center will be carried out. In addition, the International Year of Glass academic issue of “Journal of Silicate” sponsored by the China Silicate Society has been published, including 18 review articles and 13 research articles, which introduce the preparation technology, structural characterization, and application exploration of glass in detail. It is also a gift from Chinese glass technology workers for the International Year of Glass.

Tempered glass vs. laminated glass comparison and review

Laminated Glass  

What is laminated glass?

Laminated glass is made of two sheets of plain or tempered glass sandwiched around a layer of transparent plastic film (PVB). The set of glass is processed through a process designed to expel air bubbles and then heated for an initial round of melting. After this, the glass is heated under pressure to form the final bonded product. Laminated glass can be made stronger by adding layers that make the final product thicker.

Tempered glass vs. laminated glass comparison and review

What does laminated glass do?

If the laminated glass is subjected to a high-intensity impact, one side of the glass will shatter without causing the other side to shatter. Even if the glass does break on either side, the shards will stay together, creating a spider web pattern.

Some additional benefits of laminated glass are that it reduces the transmission of high-frequency sound (sound insulation) and it blocks 97% of UV radiation. A major benefit is that laminated glass with minor impact damage can be repaired with a special clear adhesive resin.

Tempered glass vs. laminated glass comparison and review

Where is laminated glass used?

Laminated glass is commonly used in high-rise building windows, skylights, balconies, and frameless glass railings. , Homeowners who live in noisy places such as airports or near golf courses often need laminated glass.

 What is tempered glass?

Tempered glass is a piece of annealed (ordinary) glass that acquires its safety properties through a heating and cooling process called “tempering”. The process involves heating the glass and cooling it immediately. Cooling incredibly hot glass quickly causes the outside of the glass to harden faster than the center. This process puts the center in tension, making the glass stronger and more durable than regular glass.

Tempered glass vs. laminated glass comparison and review

The difference between tempered glass and laminated glass is that it is a single piece of glass. Remember, laminated glass is two pieces of glass sandwiched around a piece of plastic film.

What does tempered glass do?

Tempered glass, also known as tempered glass, is stronger than ordinary glass, but easily shattered. Similar to laminated glass, when tempered glass is impacted, it breaks into a mesh interlocking pattern and remains within the frame. This is not always the case, as broken pieces will only grab adjacent pieces and may fall out of the frame.

Tempered glass is safety glass because it’s more durable than regular glass, and it’s designed to shatter into less harmful pebble-like shards, rather than sharp and jagged shards.

Unlike laminated glass, tempered glass cannot be repaired. Laminated glass can be repaired with minor damage, but damage to any part of the tempered glass will eventually cause the glass to shatter. Glass breaks because the equilibrium stress in the glass is disturbed by high-stress shocks.

Where is tempered glass used?

Flat tempered and curved tempered glass are safety glass. Widely used in high-rise building doors and windows, glass curtain walls, indoor partition glass, lighting ceilings, sightseeing elevator passages, furniture, glass guardrails, etc

Tempered glass vs. laminated glass comparison and review

Tempered or Laminated: How to Choose the Right Glass for Your Job?

Keep in mind that both tempered and laminated glass qualifies as safety glass, and laminated glass is more expensive than tempered glass. Although laminated glass is stronger than tempered glass, tempered glass is more commonly used in home windows and doors. Laminated glass is rarely used in residential construction due to its high price.

Tempered glass provides strength and resistance to breakage, but laminated glass provides UV resistance, additional security, and sound insulation. Both types of glass are easy to clean and maintain, provided they are installed correctly. After learning about the benefits of safety glass, it seems like a good idea to use it in all applications, especially when considering them for your home,

Does frosted glass also have a process distinction?

 

Frosted glass is a glass that has been rendered opaque through a process that roughens or obscures the clear surface of the glass Due to the rough surface of the frosted glass, the light is diffusely reflected, and the light is transparent without perspective. It can make the indoor light soft and not dazzling. It is often used for window glass in places such as bathrooms that need to be concealed, and can also be used for glass ceilings, which have dual functions of privacy and decoration.

The production methods of frosted glass include mechanical sandblasting, manual grinding or hydrofluoric acid dissolution.The common frosted glass process, frosting and sandblasting, is to blur the surface of the glass so that the light can be scattered evenly after passing through the lampshade. It is difficult for ordinary users to distinguish these two production processes, and they can be identified by the following methods.

frosted process: Frosting refers to soaking the glass in the prepared acidic liquid (or coating acid-containing paste), corroding the glass surface with strong acid, and at the same time, the ammonia hydrogen fluoride in the strong acid solution causes the glass surface to form crystals.Therefore, if the frosting process is done well, the surface of the frosted glass is extremely smooth, and the hazy effect is produced by the scattering of crystals. If the surface is relatively rough, it means that the acid has serious erosion on the glass, which is a manifestation of the immature craftsmanship of the frosting master. Or some parts still have no crystals (commonly known as not ground to sand, or the glass has mottled), which also belongs to the master’s poor control of the craftsmanship. This process is technically difficult. The best feature of the process is the appearance of sparkling crystals on the glass surface, which are formed under critical conditions, mainly because the ammonium bifluoride has reached the point where it is running out.

 

Sandblasting process: This process is very common. It hits the surface of the glass with the sand particles shot at high speed by the spray gun, so that the glass forms a fine concave and convex surface, so as to achieve the effect of scattering light, making the light appear hazy when passing through. The surface of sandblasted glass products is relatively rough. Because the glass surface is broken, it looks like white glass in the original clear glass. This method is moderately difficult to manufacture

 

Actually, the two processes are completely different processes. Frosted glass is more expensive than sandblasted glass, and the effect mainly depends on user needs. Some special glass is also not suitable for frosted. From the point of the pursuit of nobility, frosted should be used. The sandblasting process can be completed in general factories, but it is not easy to do the sandblasting process well.

What is Ultra Clear Glass?

Usually, we are familiar with glass brick, tempered glass, frosted glass,
Insulating glass, laminated glass, shaped glass, etc.

Regarding the door and window glass, read this article to understand

 

 

Nowadays, people pay more and more attention to the combination of architectural style and home furnishings, trying to make their houses more distinctive. As the “eyes” of architecture, the combination of doors and windows and glass has also received more attention. In this issue, I will discuss with you how to choose door and window glass to be more appropriate

Hollow glass

Generally speaking, the thermal conductivity of the sealed intermediate air layer is much lower than that of ordinary glass. Therefore, compared with single-piece glass, the thermal insulation performance of insulating glass can be increased by two times. The power consumption of air-conditioned buildings can be greatly reduced.

 

In summer, it can be insulated by more than 70%, and in winter, it can keep indoor heating not easy to lose, reduce heat loss by up to 40%, play a role in heat preservation, and make summer cool and winter warm into reality.

Tempered glass

If tempered glass is used for both indoor and outdoor glass, the impact resistance and safety of the glass are greatly improved both indoors and outdoors. Because the impact resistance of tempered glass is 5-10 times that of ordinary glass, and its bending resistance is 3-5 times that of ordinary glass, it can be said to be safe. Therefore, PVB laminated glass not only has good sound insulation performance but also has the characteristics of high strength and good explosion-proof performance. Today, when product safety is more and more important, it is widely used in high-end doors and windows and is also popular in high-end residences and villas. User’s favorite

LOW-E glass

Determine the type of glass according to the geographical location of the building: The glass in severe cold and cold areas should be mainly to control heat conduction and try to choose insulating glass or Low-E low-radiation insulating glass.

LOW-E glass is coated with a metal compound film such as silver ions on ordinary white glass. This film is easy to oxidize. Therefore, LOW-E glass is generally combined with another piece of ordinary white glass to synthesize insulating glass. Such LOW-E insulating glass has the effect of sound insulation at the same time.

LOW-E glass

Determine the type of glass according to the geographical location of the building: the glass in severe cold and cold areas should be mainly to control heat conduction and try to choose insulating glass or Low-E low-radiation insulating glass.

LOW-E glass is a thin film of a metal compound such as silver ions coated on ordinary white glass. This film is easily oxidized. Therefore, LOW-E glass is generally combined with another piece of ordinary white glass to form hollow glass. This LOW-E insulating glass also has the effect of sound insulation. Glass is one of the important components of doors and windows. Good doors and windows cannot do without high-quality glass, and a good home environment and safety cannot do without high-performance and high-quality doors and windows.

Does the self-cleaning glass

Does the self-cleaning glass need to be cleaned manually?

Easy-clean glass is usually also vividly called “self-clean glass or Auto-clean glass” in business. It generally refers to the application of a special coating on the surface of the glass, which makes it difficult for dust or dirty liquids (including liquids containing water or even oil) to adhere to the surface of the glass, or to be easily washed by water (or rain) In this way, the glass surface is very easy to keep clean, which reduces the trouble of cleaning the glass surface and also saves water resources.

This special paint is the so-called “easy-clean paint” or “self-cleaning paint”. It is developed by using two basic physical characteristics of objects in nature. The so-called easy-to-clean glass means that the surface of the glass has a high hydrophobicity similar to the lotus effect so that the water cannot be completely attached to the glass, and the surface tension of the water droplets itself produces a drop-like phenomenon. The water droplets will naturally slide off and take away the dust, making the glass have an easy-to-clean effect, The dust will not be able to accumulate, compared with the water siltation of ordinary glass, the long-term effect is quite different.

What are the categories of self-cleaning glass coatings?

Does the self-cleaning glass

The “easy-clean coatings” or “self-cleaning coatings” used on the surface of glass and ceramics on the market can be roughly divided into three categories:

Does the self-cleaning glass

1. The main component is silicone (or silicon agricultural production system resin) or other oily materials. It is coated on the surface of the material to give a greasy feeling, but it does not interact with the silicon dioxide molecules on the surface of the material to form a firm Nanofilm, but only fills up the uneven surface of the material that is invisible to our naked eyes, making the surface of the material smooth and uniform. Its advantage is that it has a strong repellent effect on water (but not oil). The disadvantage is that it has poor adhesion. In a short period of time (6-12 months), its water-repellent properties will be greatly reduced.

2. The main component is titanium dioxide (TiO2). After plating/coating a layer of titanium dioxide film on glass, titanium dioxide has super hydrophilicity due to its excellent photocatalytic properties under the action of (ultraviolet) light energy. Utilizing this super-hydrophilic property (contrary to the hydrophobic property of Golden Seal paint), it makes small water droplets converge into large water droplets, which fall off under the action of gravity, so that the stains on them can be easily Being washed away by water makes the glass easy to clean, so it is especially suitable for outdoor architectural glass. The advantage is that it is cheap, but the disadvantage is that it must be irradiated with ultraviolet rays, and the adhesion is also poor.

3. The main component is inorganic nano-silicon material, which is characterized by super-hydrophilic coating on the surface and good anti-dust. It does not rely on sunlight and works in a completely dark environment.

Plastic can exist for a thousand years, can glass be longer than it?

Plastic pollutants are the main pollutants produced by human activities. Plastics can become the main pollutants because they are difficult to degrade. If you want the plastic to degrade naturally in nature, it usually takes 200 to 1,000 years. Even ordinary plastic bags have a natural degradation time of 200 to 400 years.

Although plastic is difficult to degrade, another material used by humans is tougher than plastic and has a much longer existence in nature. It is glass. Is there any basis that glass can survive longer than plastic? Of course, there is. Because humans have a long history of manufacturing glass, as early as 1000 BC, that is, more than 3000 years ago, the ancient Egyptians had mastered the glass blowing technology.

By blowing glass, the ancient Egyptians could make all kinds of exquisite glass products. And more than 1,000 years before the advent of glass blowing, there were glass products. In other words, 4,000 years ago, humans could

Until today, archaeologists have discovered a large number of glass products from different periods, and these glass products are well preserved. This shows that there has been no effect on glass for thousands of years. Glass can be stored for thousands of years, so what if it is longer? In fact, the existence of glass in nature is much longer than you think. To know how long glass can exist, we must first understand what glass is. The main components of glass are silicon dioxide and other oxides. It is an amorphous solid with an irregular structure.

The so-called irregular structure means that the arrangement of atoms inside the glass looks messy and irregular.

mesh laminated glass

 

Under normal circumstances, the molecular arrangement of liquids and gases is chaotic, while the arrangement of atoms in solid substances, especially metal substances such as iron, is extremely orderly. Glass is solid, but the arrangement of atoms is as chaotic as a liquid. what is the problem? In fact, the atomic arrangement of glass means that chaos contains order.

On the whole, the atomic arrangement of glass is indeed irregular, but if you observe it one by one, you will find that every silicon atom is connected to four oxygen atoms. This chaotic arrangement of atoms is orderly. A special term is called “short-range order.” This is why glass is very hard but very fragile.

The special arrangement of atoms gives the glass high hardness. On the other hand, due to the extremely stable chemical properties of glass, it hardly reacts with any substance, which makes it almost impossible for glass to be corroded in nature.

, So the only way to destroy the glass is to conduct a physical attack. In nature, the erosion of wind and rain, the abrasion of sand and rock, and the movement of geology can cause the glass to break. After all, glass is very fragile. In our daily lives, we often see such a phenomenon that the transparency of newly installed glass will decrease after several years of use. This is due to the physical wear of the glass surface caused by the erosion of rain and the friction of wind and sand.

Glass partitions can give you the quietness and safety you need

What are the advantages of tempered frosted glass partition?
1. Whether at home or in the office, you want to protect your privacy and not be disturbed by the outside world. The most prominent feature of tempered frosted glass partition is that it has good sound insulation because frosted glass itself is a kind of sound insulation glass. In essence, I feel that the tempered frosted glass partition is very soundproof.

2. The toughened frosted glass partition has strong safety. The frosted glass is different from ordinary glass. When it is impacted by the outside, it will not be broken. It is intact as before. It is a protective film attached to the glass. It greatly increases safety, which is deeply loved and supported by consumers

.

3. The tempered frosted glass partition can effectively protect personal privacy. The frosted glass is opaque and can well cover the room and play an effective role in protecting privacy.

4. Although the tempered frosted glass partition is opaque, it will not block the sunlight, and the light can be well irradiated, which is very well done.

5. The tempered frosted glass partition also effectively blocks ultraviolet rays and protects furniture from fading, such as carpets, various furniture, wall hangings, etc., and effectively shields ultraviolet rays.

When choosing a tempered frosted glass partition, you must first pay attention to its material and the accuracy of the frosted glass. Attention should also be paid to the safety and explosion-proof properties of the tempered frosted glass partition, and more attention should be paid to the privacy effect of the tempered frosted glass partition. All of the above need to be paid attention to.

The hardest glass comes out? Can scratch diamond crystals and approach its strength

As we all know, the diamond, which symbolizes loyal love, is a relatively hard natural substance known in the world and is usually used to cut glass in the industry. As a raw material for diamonds (diamonds), carbon is one of the attractive elements, and exploring new forms of carbon has always been the eternal theme of scientific research.

A paper published in the National Science Review (NSR) in early August introduced a new type of glass born in the laboratory: AM-III, which is the hardest glass material known so far. Scratch the diamond crystal and approach its strength.

The producers of AM-III carbon are a group of materials scientists from Yanshan University. They found that crystalline and amorphous carbon can produce high-strength glass under a certain ratio. Molecule) After compression under high temperature and high-pressure environment, this hard carbonaceous material is formed.

In addition to superior strength, AM-III also has the characteristics of electrical conductivity and high-temperature resistance. In other words, this new material has a hardness comparable to that of diamonds, as well as good electrical conductivity that diamonds do not have. In the future, this material has broad application prospects, or it can be used in bulletproof glass, military weapons,

and optoelectronic equipment.
