What are the characteristics of commonly used architectural glass
4, insulating glass insulating glass is two or more pieces of glass with effective support evenly separated And the surrounding adhesive seal, so that the glass layer between the formation of dry gas space products.Currently on the market most of the insulating glass for the plastic seal insulating glass, and plastic hollow glass is divided into traditional aluminum and warm side seal. Swiggle warm side of the insulating glass in the world's first proposed warm edge concept and has been leading the world warm side of the development direction of insulating glass.To meet the needs of different building performance, you must use a variety of combinations of composite glass products, such as colored insulating glass , The insulating glass, the insulating glass, the glazed insulating glass, the glazed laminated glass, the interlayer insulating glass, etc. Because of the vast territory of China and the disparity between the north and the south, the requirements of the architectural glass are different. The requirements for energy saving, sound insulation and lighting requirements for buildings with different functional uses are also different. , Designers or users in the choice of glass is bound to face the question: what kind of glass, what kind of composite glass structure to meet the performance requirements of the building? Different regions and even different parts of the building should choose the same glass For the glass processing enterprises, the designer's design structure is reasonable? Is it possible for the products produced by the company to meet the design requirements? How to avoid the quality problems of the products? Will be a very critical issue.
2, laminated glass laminated glass is a layer of glass and a layer Or multi-layer glass, plastic material folder between the middle layer of glass products, the middle layer is between the glass or glass and plastic material between the bonding and isolation of the material, so that laminated glass with impact, sunlight control, noise And other properties; laminated glass is characterized by safety - even broken, it will not cause harm to people, such as car windshield glass; blocking ultraviolet light, reducing the object fade .PPB film can reduce the UV to reach more than 99%; drawback is to reduce lighting performance, Glass self-weight increase
The main application of architectural glass varieties and characteristics t0d1, tempered glass It is heated to a certain temperature after the rapid cooling method, or chemical methods for special treatment of the glass is generally based on the original ordinary float glass, after the The glass is heated to the softening point temperature and then subjected to quenching, so that the inner part of the glass has a tensile stress and the glass surface has a compressive stress and a uniform stress balance of the glass product. The tempered glass varieties include chemical steel, also known as ionization and physical steel The chemical tempered glass is characterized by the use of large particles of ions such as potassium ions to replace the sodium ions on the glass surface, at a temperature of about 400 degrees through a certain process to complete; chemical tempered glass can be cut, hot bending, etc. The strength of the glass after the high temperature processing will be affected; the initial strength of the chemical tempered glass can reach 6-7 times the original film, but with the use of time longer, the performance will be attenuated; due to the special nature of ion exchange, most used in the ultra-thin On the glass. Physical tempered glass is characterized by high strength, the general strength can reach 4 times the ordinary flat glass Right; safety - tempered glass immediately broken into small particles without sharp corners; the disadvantage is the possibility of self-violence; physical tempered glass also exists in two varieties that are all tempered glass and heat-strengthened glass, heat-strengthened glass There is no autistic phenomenon, but the strength is only about twice the ordinary glass, most of the applications in high-rise buildings, improve wind pressure performance; heat-enhanced glass does not belong to safety glass .
3, coated glass coated glass commonly known as heat reflective glass, including sunlight control coated glass and low-emissivity coated glass (Low-E) The two principles of the coating are formed by plating a metal or a metal oxide / nitride film on the surface of the original glass to reduce the shielding factor of the glass, also known as low-emissivity glass, low-e glass A low-emissivity coated glass can also be combined with sunlight control function, known as the sun-controlled low-emissivity glass.There are two series of varieties of glass, One is an on-line coated glass, also known as vapor-phase deposited coated glass; one is off-line coated glass, also known as magnetron sputtering coated glass. On-line vapor-phase evaporation coating glass is characterized by persistent / damaged impedance, no production process restrictions; Can be tempered, cut, hot bending and other secondary processing; no edge and sealing compatibility issues; magnetron sputtering coated glass is characterized by a wide range of product performance and use; sputtering procedures require employees to have good operation Habits; secondary processing process need to delete the edge; synthetic insulating glass used in the sealant must be compatible with the film; can be made of glass made of steel Coated glass, most can not be directly used for steel; most can not be off-site processing, and must be completed in the coated glass production as soon as possible after the synthesis of synthetic hollow glass .
