What are the important factors affecting the quality of impregnated paper?

Impregnated paper can be divided into low-pressure paper and high-pressure paper. The former is mainly used for furniture and laminate flooring, and the latter is mainly used for fireproof boards. Furniture and wood floors made of impregnated paper have water resistance, wear resistance, heat resistance, pollution resistance and certain light aging resistance. The veneer of wood-based panels with impregnated paper not only improves the utilization rate of wood, but also makes up for the natural defects of wood, and is a good substitute for high-quality wood.

There are many factors that affect the degree of pre-curing of impregnated paper, and pre-curing also has an important impact on the quality of paper. Let's take a look at this knowledge.

The degree of pre-curing refers to the degree of pre-curing of paper. The degree of pre-curing reflects the fluidity of the resin after being heated and pressed to a certain extent. Generally, the lower the pre-curing degree, the better the fluidity of the resin and the greater the shrinkage.

If the pre-curing degree of the impregnated paper is high, the surface of the pressed sheet will produce a lot of dry flowers, surface cracks, and poor surface clarity. If the pre-curing degree of the paper is too low, the water vapor resistance and pollution resistance of the pressed sheet product will be poor.

In summary, when producing impregnated paper, it is very important to master the degree of pre-curing, which will directly affect the quality of the paper.
