How much do you know about glass materials?

The use of glass in decoration is very common, from exterior wall windows to interior screens, door panels, etc. The simple classification of glass is mainly divided into flat glass and special glass. Flat glass is mainly divided into three types: up-set float glass (with or without groove), flat-drawn float glass, and float glass. Float glass is becoming the mainstream of glass production due to its uniform thickness, flat and parallel upper and lower surfaces, high labor productivity and good management. There are many types of special glass, and the most common ones are described below:

1. Ordinary flat glass

1, 3--4 centimeters, mm is also called a centimeter in everyday life. What we call 3mm thick glass refers to 3mm thick glass. This glass specification is mainly used on the surface of picture frames.

2.5-6mm thick glass, mainly used for small area light-transmitting shapes such as exterior walls, windows and door leafs.

3.7mm to 9mm thick glass, mainly used in large area constructions with frame protection, such as indoor screens.

4, 9--10mm glass, can be used for large area interior partitions, railings and other decoration projects.

5, 11--12mm glass can be used in floor spring glass doors and some partitions with high traffic flow.

6. More than 15mm thick glass is generally sold in the market for less, and often needs to be ordered, it is mainly used for the entire glass wall of the outer wall of the floor spring glass door with a large area.

2. Other glass

1. Strained glass. It is a kind of prestressed glass that is recycled from ordinary flat glass. Compared with ordinary sheet glass, tempered glass has two characteristics: 1) the strength of the former is several times higher than that of the latter, the tensile strength is more than 3 times higher, and the impact resistance is more than 5 times higher. the last one. 2) Tempered glass is not easy to break, even if it is broken, it will be broken into particles without sharp corners, greatly reducing the harm to human body.

2. Frosted glass. It also matte on regular flat glass. Generally, the thickness is less than 9 centimeters, and the thickness is mostly 5 or 6 centimeters.

3. Sandblasted glass. The performance is basically the same as frosted glass, the difference is that frosted glass is sandblasted. Because they are visually similar, many owners and even decorators confuse them.

4. Embossed glass. This is a kind of sheet glass made by rolling. Its biggest feature is that it is transparent and opaque, and is mainly used in decoration, such as toiletetah.

5. Reinforced glass. It is a kind of impact-resistant sheet glass, made by winding metal wire or metal mesh into a glass plate by rolling. It will only form radial cracks when struck, and will not fall or hurt people. Therefore, it is mainly used in high-rise buildings and factories with strong vibration.

6. Hollow glass. The bonding method is often used to hold two pieces of glass at a certain interval. The interval is dry air, and the surrounding area is sealed with sealing materials. It is mainly used in decoration projects with soundproofing requirements.

7. Laminated glass. Laminated glass usually consists of two pieces of ordinary flat glass (it can also be tempered glass or other special glass) and an organic bonding layer between the glasses. When damaged, the fragments still stick to the adhesive layer, which avoids injuries from splashing fragments on the human body. It is mainly used in decoration projects with safety requirements.

8. Bulletproof glass. In essence, it is a kind of laminated glass, but the glass is mainly made of high-strength tempered glass, and the number of intermediate layers is relatively large. It is mainly used in decoration projects with very high security requirements, such as banks or luxury homes.

9. Hot glass bending. Curved glass is made from flat glass that is heated and softened in a mold and then annealed. It appears more and more frequently in some high-end jewelry and needs to be ordered and is out of stock.

10. glass bricks. The production process of glass bricks is basically the same as that of flat glass, the difference lies in the molding method. Dry air in the middle. It is mainly used in decorative projects or light-transmitting molds with thermal insulation requirements.

11. Cellophane. Also known as glass film, it comes in a variety of colors and patterns. Depending on the characteristics of the paper film, it has different properties. Most of them play the role of heat-insulating, anti-infrared, anti-ultraviolet and explosion-proof.

12. Painted glass. Glass, also called back-painted, is divided into flat glass baking varnish and frosted glass baking varnish. This is a kind of colored glass, using which the smooth side will be turned inside out, and the other side will be painted with paint. This is baking a special paint on the back of clear glass and baking it in a high-speed oven for an hour. In many places where painted glass is made, it usually dries naturally, but the paint surface that dries naturally has relatively low adhesion and easily falls off when wet. environment. The reverse painted glass has a strong decorative effect.volume. It is mainly used in wall and background wall decoration, and is also suitable for indoor and outdoor decoration anywhere (among them, most of them are used for suspended ceilings).

13. Double-glazed windows with high performance. In addition to sealing dry air between the two layers of glass, high performance double glazing also needs to be covered with a special metal film with good thermal performance on the side of the air gap in the middle of the outer glass, which can block solar ultraviolet rays from entering the room during office decoration. energy. Its characteristic is that it has good energy-saving effect, thermal insulation and heat preservation, and improves the living room microclimate. In appearance, there are eight kinds of flowers, which are full of excellent decorative art value.
