A brief introduction to the operating procedures of pvc blister film pressure

PVC film lamination technology is very important in the home improvement industry, especially in the production of door frames and kitchen cabinets. The high-density plates are produced and processed into various linear shapes, and then a variety of matte trimming, patterned, and layered PVC films are applied, so that the products are diverse and have everything, creating a great deal for customers. Pick an interior space. Next, the editor will briefly introduce the operating procedures of pvc blister film pressure. 1. The use of absorbing plastic requires that the absorbing plastic is a two-component adhesive, and the activation temperature is about 60 degrees. The storage environment temperature must be between 5°C and 30°C, below 5°C will cause flocculation. Glue buckets should not be placed directly on the ground, but should be placed on wooden brackets, especially in winter. The validity period of the blister is 6 months from the date of delivery when the original packaging is not removed. The ratio of the main agent of plastic suction: curing agent u003d 20:1. When mixing the main agent and the curing agent, the main agent should be kept in a stirring state, and the curing agent should be slowly added and stirred for at least 3 minutes. The amount of glue prepared each time should be used up within 4 hours. After mixing the glue, the glue bucket should be tightly covered. 2. The glue spraying process requires the glue spraying sequence to be end face - front line type - front + line type - end face, the plane part can be sprayed once; the end face and plane line type need to be sprayed twice. The active time after mixing the main agent and curing agent is 4-6 hours, and the workpiece that has been sprayed should be processed within 4 hours to obtain the best gluing effect. Otherwise, the activation temperature needs to be increased due to the cross-linking reaction of the glue. Although the gluing effect is good in appearance, the temperature resistance has been significantly reduced. If the glue is sprayed twice, glue marks will appear on the surface of the pvc blister film. After spraying, the surface is whitish and dry, and it is not sticky to the hand or has obvious gloss after drying. The drying time is 30-50 minutes (depending on the temperature, humidity and spray quality of the environment). 3. The use of the silicone film of the blister machine should choose different thickness of the silicone film according to the characteristics of the workpiece line type (such as arc value, edge angle, width and depth of the line shape, etc.). Because the silicone membrane is often heated and stretched, its sagging will increase. It should be installed in time according to the sagging degree of the silicone membrane to reduce the sagging. In order to prolong the service life of the silicone membrane and prevent quality problems of the workpiece, the direction of use of the silicone membrane should be changed regularly, such as the front end changing to the rear end, and the left end changing to the right end. If there are holes or short cracks in the corners of the silicone film, it can be repaired with silicone and a film repairer. When repairing, use a flat heavy object to compact it. After drying for 24 hours, sand the repaired part with 240# sandpaper and it can be used normally. The above is the editor's introduction to the operating procedures of pvc blister film pressure.
