Door and window glass is an amorphous inorganic non-metallic material, generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw material and a small amount of auxiliary raw materials. Its main components are silicon dioxide and other oxides, which are widely used in construction.
Tempered door and window glass is to heat the float glass in a tempering furnace to a point close to the softening point, and then quickly and evenly cool it to form a uniform compressive stress on its surface, improve its mechanical strength, effectively improve its wind pressure and impact resistance, and improve its thermal shock resistance.
Hot-bent tempered door and window glass is to heat the original float glass sheet to the softening temperature, and then bend it by its own weight or external force, and make the required curved glass after natural cooling. It is mostly used for curved glass curtain walls, skylights, sightseeing elevators, indoor curved glass partitions, glass guardrails, interior decoration, furniture, etc. Characteristics of hot-bent tempered door and window glass: safety, impact strength, thermal stability are the same as flat tempered glass, and wind resistance is higher than semi-tempered glass. It is a kind of safety glass. Laminated glass is a composite glass made of two or more pieces of glass sandwiched with tough polyvinyl butyral film (PVB) under high temperature and high pressure.
Performance characteristics of laminated door and window glass: safety and noise reduction. PVB film can block sound waves, prevent ultraviolet rays, hurricanes and earthquakes. Hollow door and window glass is a glass product made of two or more pieces of glass separated by an aluminum frame filled with molecular sieve adsorbent, bonded and sealed with butyl adhesive, and then sealed with silicone adhesive or structural adhesive. It is widely used in various building curtain walls, doors and windows, indoor partitions or freezers, etc.
Shower room manufacturers tell you that low-emissivity coated glass, also known as LOW-E glass, is a thin film product made by coating multiple layers of metal compounds on the surface of float glass using magnetron sputtering equipment. It can reflect the heat emitted by heating, home appliances and human body back to the room in winter, reduce the conduction of the glass itself, and thus greatly reduce heat loss. In summer, it can reduce the heat radiation from the outside to the room and play a good role in heat insulation. Therefore, the film layer can block the heat transfer caused by indoor infrared radiation, has high reflectivity for mid- and far-infrared rays, and has excellent heat insulation performance. In addition, its various colors meet the requirements of architectural decoration.
Ordinary door and window glass is treated by special physical and chemical methods to improve the thermal shock resistance of the glass, which can ensure that it will not break within 45-90 minutes under flame impact and high temperature, thereby preventing the flame from spreading through the glass and giving people enough time to evacuate the scene, extinguish the fire and rescue the disaster. The performance characteristics of fireproof glass: light transmission, fireproof, smokeproof, and high strength. If you want to know more about the price of low-e glass and the content of door and
