In the market, many people do not know much about ground glassfiber powder and glassfiber chopped strand, which are often confused. Today, we will introduce the differences between them:
The ground glassfiber powder is used to crush the glassfiber filaments (leftovers) into different lengths (meshes) by the crushing process, and the glassfiber chopped wires are made into different lengths by the cutting process
Advantages of glassfiber chopped strand: high fiber length precision, high fiber content, consistent monofilament diameter, good fluidity of the fiber before dispersion. Because it is inorganic, it does not generate static electricity, and has high temperature resistance. The tensile force in the product is consistent, and it can form a three-dimensional three-dimensional network structure, so that the product has good willfulness and resistance to Zhang, high impact strength, and the fiber dispersion length in each corner of the product is consistent, Therefore, the tensile strength of products is consistent.
The grinding of glassfiber powder can not be done because of the crushing process. The length of the fiber can not be guaranteed. There are both long and short. There is also powder, because it is a waste material pulled by wire drawing workers. There are many impurities in it. The diameter of the monofilament is not guaranteed. The fiber is thick and thin. Therefore, the strength can not be guaranteed after the product is added. The strength values of each corner are different, and it is easy to stagger.
