PVB laminated glass for safety insulation and noise reduction
PVB glass sandwich film is a kind of polymer material made of polyvinyl butyric aldehyde resin, plasticized and extruded by plasticizer 3GO(triethylene glycol diisocrylate). PVB glass sandwich film thickness is generally 0.38mm and 0.76mm two, has good adhesion to inorganic glass, has transparency, heat resistance, cold resistance, wet resistance, high mechanical strength characteristics. PVB film is mainly used in laminated glass, which is sandwiched between two pieces of glass into a layer of PVB film with polyvinyl butyral as the main component. PVB laminated glass is widely used in construction, automobile and other industries because of its safety, heat preservation, noise control and UV isolation functions.
PVB film with special formula production in aerospace, military and high-tech industry and other fields also has a wide range of applications, such as aircraft, spacecraft, military instruments, solar cells and solar receivers, in the industrial field used in composite shock absorbing steel plate.
In the external impact, due to the elastic intermediate layer has the effect of absorbing impact, can prevent the impact of penetration, even if the glass is damaged, only produce similar spider mesh fine crack, the debris firmly adhere to the intermediate layer, will not fall off scattered injury, and can continue to use until replacement.
PVB laminated glass is very tough, even if the thief cracks the glass, because the middle layer is firmly adhered to the glass, still maintain integrity, so that the thief cannot enter the room. The installation of laminated glass can eliminate the guardrail, save money and beautiful can also get rid of the feeling of cage.
Due to the damping function of PVB film on sound wave, PVB laminated glass can effectively inhibit the transmission of noise, especially in the airport, station, downtown and road on both sides of the building after the installation of laminated glass, the sound insulation effect is very obvious.
4.UV protection performance
PVB film can absorb more than 99% of the UV, so as to protect indoor furniture, plastic products, textiles, carpets, artworks, ancient cultural relics or commodities from the fading and aging caused by UV radiation.
Laminated glass made of PVB film can effectively reduce sunlight penetration. With the same thickness, laminated glass made of dark low transmittance PVB film has better heat barrier ability. At present, laminated glass produced in China has a variety of colors.
Range Of Application
1. In Europe and America, most building glass adopts PVB laminated glass, which is not only to avoid injury accidents, but also because PVB laminated glass has excellent anti-seismic invasion ability. The intermediate film can resist the continuous attack of hammer, wood chopping knife and other weapons, and the special PVB laminated glass can also resist the penetration of bullets for a long time, which is a very high degree of security.
2. In modern living room, whether the sound insulation effect is good or not has become one of the important factors for people to measure the quality of housing. Laminated glass using PVB film can block sound waves and maintain a quiet and comfortable office environment. Its unique UV filtering function not only protects people's skin health, but also makes valuable furniture and display products in the home get rid of fading doom. It can also reduce the transmission of sunlight, reducing the energy consumption of refrigeration.
3. Many advantages of PVB laminated glass, used in home decoration will also have unexpected good results. For example, many home doors, including kitchen doors, are made of frosted glass. Cooking kitchen smoke is easy to accumulate on it, if you use laminated glass instead, there will be no trouble. Similarly, the large glass space in the home is a safety hazard for children who are naturally active. If laminated glass is used, parents can be greatly relieved.
4. PVB laminated glass breaks safely and may break under heavy ball impact, but the whole piece of glass remains monolithic, with fragments and small sharp fragments still sticking together with the intermediate membrane. Toughened glass requires a lot of impact to break, and when it does, the whole glass bursts into countless fine particles, leaving only a few broken glass in the frame. Ordinary glass will break upon impact, the typical breaking condition, resulting in many long sharp fragments. When laminated glass is broken, mirror tooth fragments surround the entrance, and more glass fragments are left around the penetration point, and the length of wire fracture is different.
The company's products have passed China compulsory quality system CCC certification, Australia AS/NS2208:1996 certification, and Australia AS/NS4666:2012 certification. In addition to meet the national production standards, but also meet the overseas market quality requirements.
