How to ensure the quality of impregnated paper production and processing?

1. All production materials should be used after passing the inspection. The unqualified ones must not flow into the production line, and high-quality decorative base paper must be used. And in the process of dipping, it is necessary to strictly follow the process requirements to ensure that the amount of glue, volatile content and pre-curing degree meet the technical requirements.

2. Pay attention to the complementary effect of aldehyde resin and melamine resin, especially when producing light-colored melamine decorative paper, the opaque component of aldehyde resin will enhance the hiding power of impregnated paper after hot pressing and avoid melamine through the bottom. Selection of resin.

3. In the production of impregnated paper, when the decorative base paper is impregnated with resin, it is easy to leave pores on the surface of the paper by impregnating low-weight paper with melamine resin alone.

When choosing the product of the impregnated paper manufacturer, you should first check whether the white embryo is smooth and smooth, so that the white embryo can be processed.

After sealing the primer, it is completely dry. You can lightly sand it with old sandpaper until it is almost smooth. Then all nail holes and obvious gaps, such as sticky joints, are filled with putty.

When the putty ash scraped off with impregnated paper is completely dry, it can be sanded. Here, a sand mill or belt machine can be used, but all flat workpieces must pass through the belt machine to secure the workpiece.

The flatness must also be polished to be smooth, smooth, ash-free, ash-free, fiber and large sand marks.

After operation, carefully check the paper impregnated for offset printing and smearing, and provide strict protection to ensure that the quality is intact.
