The shrinkage of the glasses plate is due to the addition of various chemical reagents in the production process of the plate, and the material itself also contains moisture, which is generally more than 25‰. Shrinking (ie baking) in the production process of glasses is traditionally used in high-temperature ovens and infrared ovens to bake, which can only reduce the surface moisture of the sheet material, and the moisture in the core does not change, and it is more prone to deformation and shrinkage. Case! Now there is an electromagnetic wave oven that perfectly solves this problem. The processing time is half an hour, the time is short, and the efficiency is high. It can effectively remove the acetic acid, water, chemical additives, etc. in the sheet production. The later roller and polishing effects are better, and More cost-saving than traditional baking methods!
