Common problems in the production of composite aluminum foil sealing gaskets are usually delamination, wrinkles, and inability to heat seal. Introduce the common small problems in the production of composite aluminum foil sealing gaskets:
When the composite aluminum foil sealing gasket is processed, the delamination is caused by insufficient glue in the production process, and the sealing gasket glue composite aluminum foil sealing gasket has the following aspects: the problem of curing time, and the insufficient temperature of the curing chamber, which leads to curing. Insufficient evaporation of the agent. The problem of raw materials may be that there is no corona on both sides of the raw materials, or the thermal cover and the corona surface are reversed to compound. When faced with the sealing gasket of double paper, the weather may cause the wax not to dry, but the more important thing is that there are many kinds of paper, and the fiber strength of the paper is not the same. At that time, there is a risk of inconsistency of the paper wax when waxing. .
The composite aluminum foil sealing gasket is placed too long to exceed the shelf life, which is easy to happen on the paper gasket. After a long time, the paper and wax will change due to contact with air, moisture, high temperature and other factors, thus starting to separate at the edge. The ratio of glue and curing agent is improperly prepared, or the unsealed storage is improperly infiltrated into impurities, or the evaporation caused by the problems of the compounding machine and the compounding production environment.
The problem of the sealing gasket compound equipment may be insufficient tension adjustment, insufficient pressure, or wear and tear of the rubber roller, which may cause the glue to fail to be scraped, or insufficient curing solvent evaporation due to insufficient oven temperature.
