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 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.

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.
