The laminated glass overcomes the weakness of common glass, broken laminated glass fragments can still be adhered to the laminated film, and the surface of the glass can still be smooth and complete, so that personal injury is avoided to a great extent. Laminated glass has excellent performance and has attracted more and more attention. In countries such as europe and the united states, laminated glass has been used in most buildings because of its good safety and strong safety. In our country, laminated glass has also begun to enter our lives as economic and social progress has been made. Except that the security performance is good, doubling glass still has fine syllable-dividing effect, is difficult to accumulate the oil smoke, and these advantages all play an important role in daily life.

The laminating process for glass processing can be applied in a large scale, and the quality improvement effect is mainly achieved by a dry laminating process, namely a laminating process of a film.
The PVB film method is to clamp the PVB film between two or more pieces of glass. Cutting and cutting the film (PVB is clamped between two or more pieces of glass) — "preheating and prepressing (the semi-finished product after laminating is preheated and prepressed to remove the air between the glass and the film) —" placing in a high-pressure autoclave, and pressing and laminating under the condition of high temperature and high pressure in the high-pressure autoclave to obtain the laminated glass.
The EVA film method is characterized in that high-temperature vacuumizing is performed, an EVA film is used for assisting in the middle of two or more pieces of glass, the whole glass is placed into a high-temperature laminating furnace for heating, bubbles are completely pumped away after high-temperature melting, the laminated glass equipment adopts a vacuum heating principle, after the glass is placed into a vacuum bag, the glass air in the vacuum bag is emptied by a vacuumizing system, so that a vacuum state is achieved, the situation that the bubbles cannot be generated between the glass is ensured, the glass is pressed by vacuum pressure, the film is melted under the high-temperature state, and the two pieces of glass are firmly bonded together.

(2) The production equipment specifically comprises: constant temperature and humidity sheet-combining chamber, preheating and prepressing roller press, air compressor and glass autoclave
(3) The investment is large, about 80-150 ten thousand.
(4) Manual work: about 5-7 people.
(5) Power consumption amount: the power consumption is large, about hundreds of kilowatts.
(6) The processing time is long: the one-pot time is about 5-7 hours.
(7) The occupied area is large.
(8) The production cost is high, and the production cost is high,
(9) can not be processed and produced in site in different places.
2. The EVA film method needs the following equipment cost:

(3) The investment is little, about 10-30 ten thousand.
(4) Manual work: about 2-3 people.
(5) Power consumption amount: the power consumption is slightly less, 25-50 kilowatts.
(6) Processing time: the one-furnace time is about 95 to 120 minutes.
(7) The occupied area is slightly smaller than that of the autoclave.
