- The main classification and main ingredients of aluminum foil adhesive:
- Generally divided into three types
- 1. Aluminum foil adhesive whose main component is water-based acrylic polymer emulsion.
- 2. Aluminum foil adhesive whose main component is polyvinyl acetate emulsion.
- 3. Aluminum foil adhesive whose main component is polyvinyl alcohol.
- Aluminum foil adhesives whose main component is an aqueous acrylic polymer emulsion generally have the following properties:

- Operation process of aluminum foil glue:
- 1. Clean the compound machine, pour the glue into the storage tank for recycling or directly add it to the glue tank. The temperature in the drying tunnel is 70-95 ° C, and the running speed is about 30-50 m / min.
- 2. The gluing amount is about 5-10 grams per square meter, the air humidity is 60% at 25 degrees, and the paper humidity is 16-20%; the aluminum foil glue 25Y of Shandong Huacheng Gaoke Adhesive Co., Ltd. is 6 g per square. Meter.
- 3 The remaining glue glued on both ends of the rubber roller is rolled for a long time, and after curing, it enters the glue tank. Putting on the rubber roller may cause the composite cardboard to have irregular fine particles. In order to prevent this phenomenon, circulating glue should be used, and the circulating pump suction pump head should be tied with 200 mesh nylon filter cloth, so that the glue solution can be used after filtering.
- 4 When the boot time is long, if there are too many bubbles in the rubber tank, the rubber roller may be locally lack of glue. Use the factory's special defoamer for spray defoaming or adding after mixing.
- 5. In humid weather, the humidity is too high, and the curing speed of the glue is slow. You can adjust the speed by appropriately lowering the machine speed or increasing the drying tunnel temperature.
- 6. If the four corners of the composite paperboard are lifted up, it may be due to the excessive glue application, which causes the adhesive layer to contract too much. Or due to the high moisture content of the cardboard itself, it should be properly controlled.
