Do you know what is glass clip film? Glass laminated film belongs to industrial glass, this kind of glass is more common in the industrial industry. Corner glass is also called laminated glass, this kind of rupture is generally made of two layers of glass, it will use a layer of adhesive film in the middle for pressing. The color of the glass clip film is generally white, which is a relatively safe glass. Now many building Windows will choose glass sandwich film production. Let's take a look at the production process of glass clip film.

First, the production process

The combination of light source and glass products breaks through the traditional concept of architectural decoration materials. It can design patterns in the glass in advance, and achieve controlled changes through DMX full digital intelligent technology in the later stage, and freely control the light and shade of the LED light source and changes. The interior is completely transparent wire, different from ordinary wire, can not see any line on the glass surface; After special treatment in the later stage, both technical requirements and safety requirements have reached the relevant national certification standards.

1. Look at the sign and check the certificate

Since the safety glass product certification was carried out in 2003, most of the country's building laminated glass production enterprises have passed the product certification, enterprises must silkscreen or paste 3C mark on the body of the product sold, or add 3C mark on its outer packaging and accompanying documents (such as certificate of conformity). When purchasing products, we must first check whether there is a 3C mark, and according to the enterprise information, factory number or product certification certificate through the network to see whether the purchased product is within the scope of the enterprise has passed the mandatory certification, and whether the certification is valid.

2, look at the appearance to check the quality

Check the appearance quality of the product, laminated glass should not crack, degumming; The length or width of the explosive edge should not exceed the thickness of the glass; Scratches and abrasions should not affect use; Defects such as bubbles, impurities or other observable opacities in the intermediate layer shall not exceed the requirements of the GB/T15763.3 standard. In the process of use, the external impact should be avoided as much as possible, especially the tempered laminated glass to avoid the impact. When cleaning the glass, be careful not to scratch or scratch the surface of the glass, so as not to affect its optical performance, safety performance and beauty. Laminated glass should use neutral glue when installing, and it is strictly prohibited to contact with acid glue.

PVB sandwich film

PVB layer is believed to be one of the more familiar names. PVB is also a widely used sandwich material for architectural glass and automotive glass. The storage process and processing method of PVB interlayer are more complicated than EVA, and the requirements for temperature and humidity are higher. PVB processing requires the temperature to be controlled between 18℃-23℃, the relative humidity to be controlled at 18-23%, PVB to maintain 0.4%-0.6% moisture content, through the process of preheating rolling or vacuuming is the use of autoclaved heat preservation pressure

Autoclave temperature: 120-130℃, pressure: 1.0-1.3MPa, time: 30-60min. PVB complete production equipment needs about 1 million funds, which is difficult for small businesses. In a few years ago, mainly to foreign Dupont, Shou Nuo, water and other manufacturers, domestic PVB is mainly recycled materials for secondary processing, but the quality stability is not very good. In recent years, domestic PVB manufacturers are also gradually developing.
