How to solve the crystal point on the PE protection film?
3, processing conditions, improper processing temperature will lead to poor plasticizing or plasticizing of raw materials, will cause crystal point phenomenon.4, equipment processing capacity, equipment, cartridge, screw, filter and so on, the crystallization of the point also has a very important impact.
2, the choice of raw materials, a variety of raw materials refers to the difference between large, poor compatibility of raw materials prone to crystal points, therefore, the choice of raw materials is very important.
The main reason of the crystal point of the PE protective film is the following reasons:1, the cleanliness of raw materials, including the cleanliness of the raw material itself and the dust pollution of the environment; therefore, attention should be paid to the production of PE protective films.
