Classification of safety glass:
First, architectural glass
1. Construction laminated glass
At present, there are two main types of laminated glass in construction, one is wet laminating and the other is dry laminating. Wet laminating is a traditional glue laminating. There are two main methods for dry laminating, one is to use EVA film lamination, and the other is to use PEB film lamination.
Both wet lamination and PVB lamination have certain drawbacks. The strength of the wet laminated glass is not enough, and the safety effect should not be achieved. In addition, the construction laminated glass made by the wet laminating method has problems such as yellowing, degumming and bubble generation, so the wet laminating is gradually stepping down. Exiting the market; PVB film laminated glass is relatively strong, but PVB film laminated glass must be completed with a roller press and autoclave, and the processing cost is also very high, so it is not suitable for SMEs. The current EVA film laminated glass just solves the defects of the original two glass production laminating process, its workmanship is simple, the initial investment is small, the processing cost is low, and the glass produced does not have yellowing, degumming, bubble generation, etc. It is gradually becoming a substitute for new building laminated glass and occupying the market.
2. Architectural curved laminated glass
Architectural curved laminated glass is mainly used for curtain walls, exterior windows, columns, spiral stairs, etc. The demand for it is relatively large, and the curved laminated glass that appears on the market now mainly has a hot-bending laminated glass and a bent steel laminated glass. The previous processing technology mainly used PVB film lamination, but the process of using VB film to bend the lamination is more troublesome than flat laminating. Mainly because the PVB film is used to bend the rubber, it needs to use the silica gel strip, then enter the constant temperature chamber, and finally enters the autoclave. The production process is very troublesome, and the cost of the silicone strip is very high, especially when the amount used on the architectural glass is very high. Large, wasting costs, so in addition to the PVB film laminated on the windshield of the car, the general processing is no longer used in the construction. The use of EVA film for curved laminated glass is very simple, similar to the process of flat-plate adhesive, so it has gradually been adopted by the market.
3. Bulletproof glass
Mainly used in bank counters. The bulletproof glass processing mode is wet, EVA film and PVB film, and all three bulletproof glass can obtain production license. In general, the safety performance and processing technology of EVA film bulletproof glass are superior in the market.
Second, art glass
1. Clip real glass:
The original flower glass was originally from South Korea. Its processing technology has been a blank in China due to the thickness and color of the real flower. Until the first exhibition of the true glass in Shanghai in May 2009, our customers began. In the high-end market of some large and medium-sized cities, the market prospect is very good.
2. Wire cloth cloth glass:
The wire cloth is made of film and silk cloth in the middle of two pieces of glass. This glass was originally from Korea. The brushed glass is used for sliding and sliding of the bedroom to provide an aesthetic and safe effect. Since a large amount of air bubbles may appear in the wet cloth glass by the wet method, the glass cloth cannot be used for the PVB film. Therefore, the wire cloth can only be made with EVA film, which provides customers with a large market development space, and from the perspective of the domestic wire cloth glass market, the profit is very considerable.
3. Color laminated glass:
Color laminated glass is mainly developed instead of baking lacquer glass. Its method is to use two pieces of glass to sandwich the color film. This color laminated glass is more radiant than the lacquered glass and has higher safety performance. . Color laminated glass is mainly used for KTV floor, hotel decoration and high-end decoration.
4. Coffee table glass:
The coffee table glass is from Shandong Province. The method is to use two pieces of glass with amber material or marbled material in the middle to make the laminated glass. Because of the beauty and atmosphere of the coffee table glass, and the market price is moderate, its market is very good.
5. Strengthen the glass:
The tempered glass is a layer of glass attached with a layer of reinforced material to achieve a safe and beautiful effect. The processing technology is very simple, the pattern is relatively more, the safety performance is higher, and it is well received by customers, and the market prospect is very broad.
6. Closet door:
The closet door is made of glass and MDF bonded together with film to provide an aesthetic and safe effect, especially when using 2mm--3mm tempered glass, the effect will be better. At present, the market for closet doors is very mature.
7. Marble laminated glue:
Marble Latex is an emerging decorative product that is made up of two layers of glass interlayer sandwich marble. Because this product uses natural marble, it will display different colors under different light, so it is generally used in high-end places, and its profit margin is quite large, which is deeply loved by customers.
Third, new energy
1. Solar photovoltaic panels:
The fabrication of solar photovoltaic panels is made up of silicon crystal plates and circuit boards. It was previously made using a laminating machine, but the cost of the laminating machine is relatively high and the output is very low, so the laminating machine is being phased out. . The processing technology of EVA laminated glass equipment is quite simple, and the output is very high, and now it has gradually become the market's first choice.
2. Conductive glass:
Conductive glass is made up of two layers of glass with a layer of conductive plates. It can be controlled by AC power and is generally used in many high-end products. The market in Europe and America is quite good.
3.LED glass:
LED glass is made up of two layers of glass plus LED boards. It can signal when it is energized, and is generally used in the aviation field. All of the current Southern Airlines aircraft use LED glass.
4. Electric glass:
The electric glass is made up of two layers of glass with electric heating wire and film composite, which is mainly used on trains. One is to avoid frost on the glass and affect the line of sight; the second is to ensure safety.
