Vertical arranging method of laminated glass in autoclave

Abstract

The invention relates to a vertical arranging method of laminated glass in an autoclave. The method comprises the following steps: vertically and fixedly arranging laminated glass in a kettle feeding vehicle in parallel, and arranging an accommodating groove in a position of the bottom of the laminated glass, corresponding to internal adhesive sheets, in order to accommodate the adhesive sheets at a high temperature under a high pressure and discharge air. The laminated glass sheets are vertically arranged in the kettle feeding vehicle to prevent mutual expression pressure between laminated glass sheets and eliminate bowl-shaped optical deformation, and the bevel cushion block of the bottom is improved to prevent bubbles at the bottom adhesive film, so the laminated glass has beautiful profile.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a vertical stacking method for laminated glass in an autoclave. Background technique [0002] Autoclave is the key equipment used for glass interlayer. This equipment makes the film and glass bonded into transparent laminated glass through heat treatment processes such as pressurization and heating. In order to maximize the utilization of the space in the autoclave and maximize the utilization efficiency, the laminated glass is generally pushed into the autoclave by an oblique vertical stacking method. There is an A-shaped bracket on the car, and the laminated glass is stacked on both sides of the A-shaped bracket. The upper and lower ends of the laminated glass are separated by spacers, and a beveled pad is added at the bottom. , so that the bottom as a whole rests on the surface of the bevel block to keep the leaning against the glass stable, see figure 1 shown. How...

Problems solved by technology

However, due to the large size of the glass, when the glass is placed obliquely, the weight is all supported by the upper spacer. When the autoclave is under high temperature and high pressure, the film at the spacer between the inner glass is easy to become thinner due to extrusion. optical distortion

Before the laminated glass enters the autoclave, although the excess film on the glass end face has been trimmed and smoothed, some film will still be squeezed out of the glass end face under pressure in the autoclave, which will make the glass bottom and A-shaped The place where the bevel pads at the bottom of the bracket are in contact with the glue cannot be removed, and if they accumulate together, the gas in the film cannot be removed, and bubbles will form here. figure 2 shown

The above problems cause the overall appearance of the finished laminated glass to be poor and unsightly
