Advertising KT Board Blistering Problem

May. 12, 2020

The wet and rainy spring is gradually away, and the hot and dry summer has started to debut, and advertising manufacturers have begun to worry about "advertising KT board blistering", but they have no way to deal with this problem.

Today, KT board suppliers help you find out the real reason for "KT board blistering".

1. There are quality problems in the KT board itself:

1) The raw material used to make the core of the KT board-PS particles contain impurities, which cause the size of the enclosed molecular structure inside the core to be uneven or even destroyed, resulting in the long-term release of internal gas;

2) Use low-cost and low-quality skin materials for compounding, so that the thickness of the core skin after stretching is uneven, and the core skin is prone to blistering under thermal expansion;

3) Purchase low-cost and backward composite equipment, resulting in uneven internal structure of the board core;

4) Short curing period, cut corners. The maturation period of the board core needs to reach half a month. If the maturation time is shortened, the gas in it will not be exhausted, and it will be volatilized for a long time during the later use, and it is easy to foam.

2) In the process of making the painting, the adhesive and the KT board are not tightly attached, and the middle air is not completely exhausted.
