Laminated glass vacuum sealing machine is a kind of laminated equipment. It uses vacuum bag principle, under vacuum, the laminated materials and glass with heating, the glue solution state, so that the two pieces of glass are glued together. The machine can be EVA, PVB, SGP, functional cloth, paper products, calligraphy and UV one-way film, film, film etc. low Xie or specific film, and ordinary glass produced by heat sealing process of laminated glass multifunctional and decorative glass; can also be used for glass and PC glass plate, and solar panels and other soft plates, each composite sheet. The device does not need additional autoclave and hot press. It has the advantages of simple and reliable structure, low energy consumption, good quality, less floor area, less investment, low production cost, large production volume, wide application range and high output, which is suitable for industrial production requirements.

Tools / materials

EVA film, silk silk cloth material, laminated glass, vacuum sealing machine

Methods / steps

The prepared glass: two pieces of the same size glass grinding edge, especially glass four angle grinding arc shape, beware of scratch silicone rubber with glass processing machine will clean, dry. This point is very important.

(2) cutting EN film: cut the EN film and paper into a slightly larger than two glass size.

The tablets: a piece of flat glass, and then put on the HC-D type low temperature film, the film clip and put the paper, folded after another piece of glass, aligned corners, removal of part of the film and paper edge, with textured paper two pieces of glass four corner, to prevent walk after heating.

EVA laminated glass steps

The glass will be placed in the vacuum bag: beware of the glass into the vacuum bed, from vacuum net began to put, between the glass and the glass must be about 1 cm left airway to extract air. When the glass is full, the side part is buckled and the vacuum tube is connected. For example, the vacuum network must be stacked on the suction vent with a fastener type edge bed equipment. Detailed operation,

EVA laminated glass steps

Three

(5) start the vacuum pump. First, carefully check whether the vacuum tube connection is correct, then start the vacuum pump power, and vacuum evacuation according to the preset program. When the vacuum gauge indicator is stabilized on the scale of -0.1MPA, close the door until the whole program is completed.

The control program is set: the production of laminated glass, various technical parameters must be set in the machine box panel assembly,

7, glass cooling: at this time, the temperature inside the machine box is high, the furnace door is opened, the temperature drops rapidly. The temperature can be rapidly reduced to 40 C ~50 C by fan, and then the whole cooling process is stopped. At this time, the silica gel plate can be opened and the glass can be removed. Do not shut down the vacuum pump during the cooling process.
