convex mirrors

How well do you know convex mirrors?

A curved mirror is a mirror with a curved reflecting surface. The surface may be either convex (bulging outward) or concave (recessed inward). Among them, convex mirrors are the most common in life.

principle of convex mirrors

A convex mirror or diverging mirror is a curved mirror in which the reflective surface bulges towards the light source. Convex mirrors reflect light outwards, therefore they are not used to focus light. Such mirrors always form a virtual image, since the focal point (F) and the center of curvature (2F) are both imaginary points “inside” the mirror, that cannot be reached. As a result, images formed by these mirrors cannot be projected on a screen, since the image is inside the mirror

.

The convex mirror manufacturing process is divided into glass molding and mirror plating. In the factory, workers cut the glass into a round shape, then put it in a customized mold, put it into the furnace, and adjust the temperature according to the required arch height. The glass softens at high temperatures and naturally sags to form a curved surface. Because it relies on softening to sag naturally, the error range of the arch height is relatively large. The inspection standard is mainly based on the qualified diameter. After cooling, the qualified products are selected and sent to the plating mirror. The colored convex mirror uses colored glass as the raw material, and the silver convex mirror uses low-iron glass as the raw material.

Uses of convex mirrors


The convex mirrors that everyone sees in life are generally the plexiglass mirrors in the rear mirrors of cars or intersections. In fact, convex mirrors are also widely distributed in home and hotel decorations. This is a style that has been handed down since the Middle Ages.

Round convex mirrors called Oeil de Sorcière (French for “sorcerer’s eye”) were a popular luxury item from the 15th century onwards, Famous examples in the art include the Arnolfini Portrait by Jan van Eyck and the left-wing of the Werl Altarpiece by Robert Campin.

 

This is a popular decoration that has continued from the Middle Ages and is more common in luxurious decoration. The colored convex mirror looks like a beautiful gem from a distance, and its colors are pink, blue, black, and silver. The outer frame is generally made of brass (simple style), and gold and silver frames (luxury style) are also used. Using a suitable outer frame can make your room shine.

How to use tempered glass safely?

Reasons for strengthening glass breakage:

The tempered glass surface is a layer of compressive stress, and the internal tensile stress layer is corresponding to the balance state. When the surface flaw extends to the internal tensile stress layer, it will cause cracking.

This type of scar can be divided into several types:
Scratches caused by hard objects, sparks during welding, flying objects, etc.
Glass damage during handling and storage.
Damage to the glass when it is embedded.
Thermal stress and damage to system stress.
̇External force impact.
It is caused by impurities that occasionally exist in the glass.
unknown reason.

Characteristics of tempered glass rupture:

As long as the tempered glass is partially damaged and ruptured, it will lose the balance of stress and cause full fragmentation. Some of the fragments are scattered by granules, and some are still attached together to form a piece of fragmented aggregate. When a rupture occurs, a person in the vicinity may be hit by rain-like particles or may be hit by a large piece of aggregate. If the fragmentation block is large enough, it may hurt the human body.

Reaming or drilling of tempered glass:

After the glass is cut or drilled, the strength of the surrounding structure will be greatly weakened. In the part subjected to external force, such processing should be avoided as much as possible; if it is not, the strengthened laminated glass should be used.

When tempered glass is used in each of the following locations, it is desirable to use reinforced laminated glass:

The top of the patio is said to be used in horizontal or near-horizontal glass, such as skylights and skylights.
The outer wall of the building is used vertically. If it falls, it will hurt the objects on the ground and the glass of the human body.
Armrests or guardrails, such as glass that may cause the body or objects to fall when broken.

Do you know how to properly install a sliding glass door

With the constant innovation and development of glass industry, glass products have been fully integrated into our lives, decorate in household in the frequency of using glass is more and more frequent, and glass door is not only in the construction industry is known as often used in decorating glass products also shows its unique advantages, steel material selection is not confined to the wooden people, more is to choose about glass, glass door made of glittering and translucent get rid of appearance, not only provides the guarantee on the quality, the glass door is divided into a number of different styles, the original glass door is single or double open the door, and with the continuous improvement of people’s life,Demand for products also will increase, so the glass sliding door at this moment a big rise, attracted a lot of users, provides users with more convenient features, present the effect is better, both in terms of material and aesthetic appearance has many advantages, many users for the installation of the glass sliding door there are still some misunderstandings, so let small make up for everybody introduced several methods of sliding door of glass of installation:
Installation method of sliding glass door:

1. Hanging sliding door because the first rail box and then stick brick, exposed rail box and brick junction is not good processing, to the construction of a certain degree of difficulty.Due to the track under a certain pressure, the brick is also stressed, a long time, easy to lead to the track next to the brick cracking.Additional, if be in the space such as kitchen toilet inside, orbit box place is easy to hide filth and dirt, lampblack accumulates ash to wait to fall above, bring trouble to clean sanitation.

2. The upper part of the sliding door track box size to ensure that the height of 12 cm, 9 cm wide.Like the curtain box, the track box is installed inside the track, and the sliding door can be suspended on the track.Today most doors or openings are between 1.95 and 2.15 metres in height.Experience shows that when the height of the door is less than 1.95 meters, no matter how tall the person is, they will feel very depressed and uncomfortable.Accordingly, when making sliding door, height wants to be in at least 195+12=207 centimeters above, have enough space to make track box just can consider making sliding door.Otherwise can be external hang only, namely orbit box is exposed in the outside, affirmation is not beautiful, and time a long time, the aperture of door and metope can become big.

3. The width of the sliding door is exquisite.The normal gold size of the door is about 80 cm x 200 cm, in this structure, the door is relatively stable.If have the height of more than 200 centimeters, do sliding door below even higher circumstance, had better keep in the area below invariable premise, the width of the door shrinks narrow or make a few sliding door more, maintain the stability of the door and use security.

4. Careful use from the ground to the top of the sliding door (hanging rail box).As a result of push when swing amplitude is too big, time is long sliding door is easy to be out of shape, out of shape back door cannot open, also mean cannot repair and cannot use.

5. Because sliding door and wall or cabinet body on both sides of the contact, therefore, in the contact position do not have other objects to block the closure of the sliding door.For example, the position of the drawer inside the cabinet should avoid the intersection of sliding doors, and should be higher than the bottom at least 1cm;The drawer inside folding door cabinet body is apart from the side wall at least 15cm here special notice the power switch on the wall and socket even, if blocked the close of sliding door, should change the position of switch and socket.

6. No matter you do any material of the ground, to ensure that the level, the four walls of the door should be kept horizontal and vertical.Otherwise, the door will skew after installation.The adjustable error is no more than 10mm.

7. In the installation position please do not install the corner line, the gypsum line can be installed in the upper wall cabinet on the sealing board, if the door directly to the top do not install the gypsum line.

8.  5 mm thickness of the carpet below the location of the carpet will be cut directly paste down the track.The carpet of above 5 millimeter thickness if install double track, can fix with screw directly on carpet: if install single track, the carpet that must be in the position is cut off, the wooden strip of 3-5 millimeter thick is placed in carpet place beforehand, in order to stick single track directly above.

That is about the right way to install glass sliding door, believe that after reading the above content to install glass sliding door have a deeper understanding, on how to properly installed mastered the judgment method of strong glass sliding door, glass sliding door in our daily life plays an important role, in the aspect of furniture also adds to the window;Hope the above knowledge is helpful to everyone!

How many kinds of decorative glass are there

How many kinds of decorative glass are there?


1. Tempered glass. It is a kind of pre-stressed glass which is made from ordinary flat glass. The tempered glass has two main characteristics compared to ordinary flat glass:

1) The strength of the former is several times that of the latter, the tensile strength is more than 3 times that of the latter, and the impact resistance is more than 5 times that of the latter.
2) The Tempered glass is not easily broken, and even if broken, it will be broken in the form of particles without acute angle, greatly reducing the harm to the human body.

2. Frosted glass. It is also made by sanding ordinary flat glass. The general thickness of more than 9 cm, to 5,6 cm thickness with more.

3. Sandblasted glass. Its properties are basically similar to frosted glass, different frosted glass is sandblasted. Due to the visual similarity, many owners, even decoration professionals are confused with them.

4.Patterned glass. It is a kind of flat glass made by calendering. Its main characteristic is transparent, mostly used in toilet and other decoration areas.

5. Wire glass. It is a kind of impact resistant flat glass made by calendering and inserting metal wire or metal mesh into the glass plate. When it is hit, only radiation cracks will be formed without causing injuries. Therefore, it is mostly used in high-rise buildings and factories with high vibration, etc.

The difference between safety glass and toughened glass

What is safety glass? What’s the difference with toughened glass?

Presumably many people know toughened glass, as a result of the formation of small pieces after breaking, reduced the risk of cutting, toughened glass is applied in a number of fields, and there is another noun, called “safety glass”, this safety glass and toughened glass and what is the difference?In fact, safety glass is a class of glass collectively, the requirements of violent vibration or impact not broken, even broken is not easy to hurt people, and tempered glass is one of them.Under the classification of safety glass, there are many kinds of glass!

① Toughened glass, Tempered glass

The production of toughened glass is to quench the glass with high-speed air and other cooling media when the glass is heated uniformly to the softening temperature.The uniform compressive stress on the glass surface can improve the mechanical strength and thermal shock resistance of the glass.Using air as the cooling medium is said to be toughened;When oil and other liquids are used as the cooling medium, the liquid is toughened;When molten salt is used as cooling medium, it is called salt bath toughening.According to the degree of rigidness and the shape of the products, it can be divided into complete toughening, regional toughening, semi-toughening, plane toughening and bending toughening.The flexural strength of toughened glass is 3 ~ 5 times greater than that of untreated glass, up to 150 ~ 250 mpa, thermal stability is improved 3 ~ 4 times, can withstand the temperature difference of 200 ~ 250℃ sharp change, no sharp edges and corners of the particles formed when broken, very little harm to human body, is the most widely used safety glass.

② Laminated glass

Laminated glass is a composite glass product which is sandwiched between two or more pieces of glass with transparent polyvinyl butadialdehyde film or other adhesive materials.When under impact, due to the elasticity of the middle layer and strong adhesive force, it can improve the impact strength. When broken, the debris will not fall off or splash, which can effectively prevent or reduce the damage to the human body.In addition, special laminated glass can be made by means of heat-absorbing glass, heat-reflecting glass, color glass and conductive film glass.

③ Bullet proof glass

Bulletproof glass can be said to be the highest level of safety glass at present, it is the composite glass that USES toughened glass, chemical reinforcement glass, silk (mesh) glass and high strength organic material (such as directional plexiglass, polycarbonate, etc.), and USES interlayer craft to make.According to different requirements, different materials can be selected to form different composite structures, to achieve the ability to resist the shooting of guns and bullets in a certain distance and the effect of preventing theft.Generally used for special bulletproof or anti-theft requirements of the building and border observation post.

Glass shower room and daily use maintenance point

The advantage that installs glass shower room and daily use maintenance point

In recent years, with the rapid improvement of modern science and technology level, the ancient and traditional glass industry coruscated new life, in the toughened glass and other safety glass development mature now, a variety of glass products with unique functions have come out one after another.These glasses not only play a traditional role in transmitting light, but also play an irreplaceable role in some special occasions.Install vitreous shower room for example, and the advantage that installs vitreous shower room to bring is thought and easy to see, among them daily maintenance also has a lot of place that needs attention.

The advantage of glass shower room

1, can differentiate to wash bath space independently.Our country dweller residence toilet and lavatory are mostly close together, installation bath room is more reasonable choice.This can create a relatively independent bath space to avoid mutual influence convenient daily life.

2. Save space.The space of toilet of a few families is small, install do not fall bath crock, and shower room can save a lot of space.

3. Had shower room, below the action that stops in glass, when using shower head water won’t splash outside the ground of whole toilet gets wet.

4. In winter, the use of shower room can also play the role of heat preservation.Water vapor in a narrow space, the heat is not lost quickly, let a person feel very warm.And if toilet is bigger, do not have shower room again, although have central heating, also often feel very cold.

5. The modelling of shower room is rich, colour is bright-coloured, besides the function that has bath outside, itself still is a very good adornment.

The maintenance method of vitreous shower room

1. For routine cleaning, please rinse with clean water and clean regularly with glass water to maintain the smoothness of the glass.
Those who have bilge use neutral cleaner to wipe with soft cloth, stubborn besmirch can use a few alcohol to get rid of, avoid is used acidity, alkalescent solvent.
2. How to use and maintain the pulley of shower room.
A. Avoid slamming the sliding door under to avoid the sliding door falling off.
B. Note to add lubricant on the slide track regularly.
C. Regularly adjust to ensure the effective bearing capacity and smooth sliding of the pulley on the movable door.
