What is the impregnation process of melamine dipped paper?

In the production of melamine dipped paper, the viscosity of the glue used can be determined according to different situations. Let's take a look at its dipping process.

The first thing to learn is that impregnation is the exchange process of gum and air in the paper, so how to completely discharge the air from the paper, the amount of glue absorbed by the paper meets the technical requirements, the method of impregnation is a major factor. After the paper is dried, the permeation zone is lengthened by a single-sided dipping roller, so that the air in the paper escapes from the paper, and then enters the dipping tank for dipping. In order to control the amount of dipping and the glue does not sag, a scraper or roller is installed at the back of the dipping mechanism to maintain the amount of glue on the paper.

For the paper that needs heavy glue, the dipping method can be divided into a first dipping tank and a second dipping tank, and an infrared drying device is installed between the two tanks, so that the paper dipped for the first time is slightly dried. , and then make a second dip.
