Popular science: introduction to building glass

ordinary ceramic tile cement buildings can't keep up with the contemporary development level and can't meet the needs of consumers. Therefore, architectural glass was invented, which has the characteristics of light regulation, thermal insulation, safety (bulletproof, anti-theft, fire prevention, radiation prevention, anti electromagnetic interference), art decoration and so on. The huge demand makes the consumption of glass in buildings increase rapidly, becoming the third largest building material after cement and steel. Architectural glass is only a general term within the scope. The common subdivisions of architectural glass in life have different types and characteristics, which are introduced one by one below

flat glass

1 Glass for windows: flat glass for windows, also known as flat glass or lens glass, referred to as glass, is flat glass without grinding. It is mainly used for doors, windows and walls of buildings to break through industrial production technologies such as high melt index polypropylene, ultra-high molecular weight polyethylene, foamed polypropylene and polybutene ⑴ (PB), as well as outdoor decoration. It can also be used for shop counters, window windows and doors and windows of some means of transportation

2. Polished glass: polished glass is called mirror glass or white sheet glass. It is flat glass after polishing. It is divided into single-sided polishing and double-sided polishing. It is often used to install large high-grade doors and windows, windows or mirrors

3. Colored glass: colored glass, also known as colored glass, is divided into transparent and opaque. It can be assembled into various patterns and patterns, and is suitable for doors and windows, internal and external walls and lighting parts with special requirements for light

4. Painted glass: painted glass is a high-end decorative glass product with a wide range of uses. Screen painting technology can realistically copy the original painting onto the glass. Painted glass can be used for doors and windows, internal and external curtain walls, ceiling chandeliers, light boxes, wall decorations, furniture, screens, etc. in families, office buildings, shopping malls and entertainment places, and its different patterns and pictures can be used to achieve the decorative effect of high artistic appeal

5. Grating glass: grating glass, also known as laser glass, is a laser decorative material based on glass and formed by laser surface microlithography, which makes ordinary glass show colorful three-dimensional images under white light conditions. It is applicable to the beautification and decoration of halls, internal and external walls, door signs, billboards, ceilings, screens, doors and windows in homes, public facilities and cultural entertainment places

6. Decorative mirror: decorative mirror is an indispensable material for interior decoration. Adopt high-quality float flat glass and vacuum aluminized or silver plated mirror. It can be used for decoration of halls, columns, walls, ceilings and other parts of buildings (especially narrow spaces)

7. Embossed glass: embossed glass, also known as patterned glass or knurled glass, is a flat glass with a pattern formed by continuous calendering with a patterned roller with a colorless or colored liquid glass. Embossed glass is suitable for interior decoration in various indoor occasions with different requirements for perspective and different partitions in the range of tensile force. It can be used to process handicrafts and daily necessities such as screens, desk lamps, etc

safety glass

1 Tempered glass: tempered glass is formed by heating the flat glass to the softening temperature, cooling it rapidly to make it quench or ion exchange it with chemical method. Compared with ordinary glass, the bending strength is increased by 5 ~ 6 times, the impact strength is improved, and the data file saved to the hard disk is about 3 times higher, and the toughness is increased by about 5 times. When the tempered glass is broken, it does not form sharp angular fragments, so it does not hurt people. It is used for anti vibration and anti-collision parts such as building doors and windows, partition walls and public places. Bent tempered glass is mainly used for doors and windows of large public buildings, skylights and window glasses of industrial plants

laminated glass is a flat or curved composite glass product made of two or more pieces of flat glass bonded with transparent plastic sheets by hot pressing. Due to the plastic lining bonded in the middle, the glass will not splash when broken, resulting in radial cracks, which will not hurt people. Therefore, its impact strength is much higher than that of ordinary glass. Laminated glass is suitable for doors and windows with high safety requirements, such as doors and windows of high-rise buildings, doors and windows of buildings and basements, doors and windows of buildings such as banks, commodity display cabinets, window windows and other anti-collision parts

wired glass is made by heating ordinary flat glass to the red heat softening state, and then pressing the preheated wire or metal into the glass. Because the wired glass has uniform internal stress and impact strength, when the glass is broken by external factors, its fragments can stick to the metal wire () to prevent the fragments from splashing and hurting people. This kind of glass also has the function of isolating flames and preventing fire spreading. Wired glass is suitable for doors and windows, roofs, lighting skylights of industrial plants with large vibration, doors and windows of warehouses and libraries that need safety and fire prevention, composite external walls of buildings and transparent fences, etc

4. Burglar proof glass: burglar proof glass is a special kind of laminated glass. Generally, tempered glass, extra thick glass, reinforced plexiglass, polished laminated glass and other multi-layer composite glass glued with resin glue are used, and wires and sensitive detection elements are embedded in the middle interlayer to receive alarm devices

special glass

1 Endothermic glass: endothermic glass is a flat glass made by introducing a colorant with endothermic property into the glass solution or spraying a colored oxide film with endothermic property on the surface of the glass. Heat absorbing glass is suitable for windows and doors, curtain walls, commodity display windows of large public buildings that need to be equipped with air conditioners and avoid glare, and windshield glass of computer rooms, trains, cars, and ships, especially in hot areas, where both lighting and heat insulation are needed

2. Heat reflective glass: heat reflective glass is a coated glass made of gold, silver, aluminum, copper, nickel, ferrochromium and other metals and metal oxides sprayed on the surface by heat, evaporation, chemistry and other methods or pasted with organic films. Heat reflecting glass is the most effective anti sun glass in modern times. Heat reflective glass is suitable for doors and windows, glass curtain walls, hallways of public buildings and various decorative parts of modern high-grade buildings. It can be made into two types of double-layer hollow glass, which can be divided into vertical spring torque testing machine and horizontal spring torque testing machine, and the glass curtain wall with air layer can be formed, which can achieve excellent heat insulation and energy saving effects

3. Photochromic glass: photochromic glass is obtained by adding silver halide to the glass, or adding photosensitive compounds of molybdenum and tungsten to the glass and organic interlayer. When photochromic glass is irradiated by the sun or other light, its color will gradually darken with the enhancement of the light. After stopping the irradiation, it can automatically return to its original color. And can achieve the effect of automatic adjustment of indoor light. Photochromic glass is mainly used for building doors and windows that need to avoid glare and automatically adjust the light intensity
