Why is the melamine dipped paper warped?

Melamine dipped paper is generally used on the surface of the board, but after a period of use, the edges and corners will rise, so why do these reasons occur?

The first is the problem of construction technology. If the edges and corners of the melamine-dipped paper are left less than 2 cm, warping will easily occur. The second is the problem of basic treatment. If the surface of the board is rough, If it is too wet or too dry, it is easy to make the melamine dipped paper and the board not stick firmly, so it is easy to appear the phenomenon of warping. If the waterproofing work is not in place, the melamine dipped paper will be damp, and it will be prone to chalking, which will lead to loss of cohesion and warping.

In addition, there is another reason that the adhesive force of the melamine dipped paper is too low, so it is easy to stick not firmly, so the phenomenon of warping occurs after a long time.
