[China Glass Net] Because of the transparent lighting and heat-blocking characteristics of glass, glass is an indispensable data component for modern construction. Different types of glass are used for different construction parts, so tempered glass, insulating glass, laminated glass and other functional glass have emerged. Today, let's share with us the common knowledge of these commonly used silent door and window glass products. First, tempered glass Tempered glass is used to improve the wind pressure and impact resistance of glass by heating the float glass to a vicinity of the softening point in a tempering furnace, then uniformly cooling it, forming a uniform compressive stress on its surface, and improving its mechanical strength. Function to improve the thermal shock resistance of glass. The outstanding physical function of tempered glass has made it one of the standard for most high-end silent door and window glass. Features of tempered glass: 1. Safety: When damaged by external force, the glass will be broken into small honeycomb-like obtuse-angled small particles, which will not cause serious damage to the human body. In general, the large pieces of fragments that are relatively sharp when the glass is broken are extremely likely to cause serious damage to the human body. 2. High strength: 3-5 times higher than the usual glass strength of equal thickness. 3, heat-resistant function: excellent thermal stability, acceptable temperature is about three times the thickness of ordinary glass, can accept 200 ° C temperature changes. 4, the large degree of disturbance: 3-4 times larger than the ordinary glass of equal thickness. When the tempered glass is subjected to load, the large tensile stress is not the same as that of the glass, but the base of the tempered glass. Self-destruction of tempered glass Self-explosion refers to the phenomenon that tempered glass automatically splits without direct external force. The episode of the self-explosive scene is mainly caused by the volume expansion caused by the nickel sulfide (NIS) phase change in the glass. Because the nickel sulfide is mainly brought in by the impurities in the glass raw materials, the glass technology cannot completely eradicate the tempered glass. The onset of the scene. However, in order to reduce the appearance of self-explosion, Kadi silent doors and windows all tempered glass to increase thermal intrusion treatment technology, the tempered glass is heated to 290 ° C ± 10 ° C, and insulation for a certain time, to promote the rapid change of nickel sulfide in tempered glass crystal phase, let After the original use, the tempered glass may be artificially broken in the hot dip furnace of the factory, and then the tempered glass in the process of use after the device is reduced, and the explosion may be reduced as much as possible. Hot dip technology is also a useful method in the world to agree on the decline of self-destruction. Second, insulating glass Insulating glass is a glass product in which two or more pieces of glass are filled with an aluminum frame filled with molecular sieve adsorbent, and a space of a certain width is separated, sealed with butyl rubber and sealed with silicone rubber or structural glue. It has outstanding functions of sound insulation, heat insulation, heat preservation, anti-condensation and fogging. The outstanding energy-saving function of the insulating glass makes it one of the standard for most high-end silent door and window glass. The thickness of the spacer frame of the hollow glass of the mute door and window: 12mm (12A), 16mm (16A), 20mm (20A), 27mm (27A) The function and features of insulating glass: 1, sound insulation function: Insulating glass is the ambition of noise insulation data, usually can reduce the noise by 30 decibels, and the inert gas can be reduced by 5 decibels on the original basis. 2, heat insulation function: can be used to reduce the heat transfer coefficient U value, if filled with inert gas, can further reduce the heat transfer coefficient. 3. Anti-condensation and fogging function: Because the spacer of the insulating glass is filled with the satisfying desiccant, it can effectively absorb the water vapor that may enter the inner cavity and the outside, and ensure that the air in the hollow glass cavity is boring, thus having Outstanding anti-condensation fogging. Third, laminated glass Laminated glass is a composite glass made of a high-temperature high-pressure high-pressure film by sandwiching a tough polyvinyl butyral film (PVB) between two sheets of glass or a plurality of sheets of glass. Because the resistance of PVB film is very good, when the laminated glass is crushed by external force, the film will absorb a lot of punching technology and make it agile, because the laminated glass is difficult to be broken even if the laminated glass is broken. The glass shards are basically adhered to the film, insisting that the pieces on the entire laminated glass do not fall, so it becomes a "safety glass" in the true sense. Features of laminated glass: 1. Safety: The laminated glass of the device is impacted by any external force. Even if the glass is broken, it can adhere to the original structure intact, and it must have the effect of wind and rain. 2, anti-UV: a great insulation effect on the ultraviolet light in the sun (up to 99% or more), to avoid ultraviolet radiation. 3, bulletproof and explosion-proof: the use of multi-layer laminated glass can produce a variety of grades of bulletproof, explosion-proof glass. 4, security use: because the glass knife can not be used to implement the cut glass of the device, and the use of other things to penetrate the laminated glass for a long time, the sound is large, so by cutting or breaking the laminated glass into the room It is difficult and easy to find, and it has a strong resistance to malignant damage, theft and violence. Fourth, Low-E glass Low-E glass, also known as low-emission coated glass, is a film-based product made of multi-layered metal compounds on the surface of float glass by means of magnetron sputtering. It can be used to declare heating, household appliances and human body in winter. The heat is reflected back into the room, and the glass itself is lowered to conduct, and then the heat loss is greatly reduced. In the summer, it can reduce the outdoor heat radiation into the room and play an outstanding heat insulation effect. Therefore, the film layer can block the heat transfer caused by the infrared radiation in the room, has a high reflectance to the far-infrared rays, and has an excellent heat insulating function. Low-E glass features 1. Useful progress: visible light transmittance, ground reflectivity, low emissivity, wide lighting range, soft light quality, avoiding the occurrence of light pollution and creating an outstanding ecological environment. 2, usefully control solar radiation, block the far-infrared radiation, the heat transfer coefficient U value is lower, so that the heat insulation function is enhanced, with outstanding heat preservation and energy saving effect. 3, usefully block the transmission of ultraviolet light, to avoid the fading of indoor furniture, fabrics, art.
