Many master color companies do not know much about the use of colorants when designing PE, PP, PERT and PEX masterbatches, which causes fading problems for downstream customers, and the root cause is not clear, causing losses to customers. Therefore, when designing and producing the masterbatch of PE, PERT, PP and PEX, it is not only necessary to pursue bright colors, but also to consider factors such as temperature resistance, migration resistance, sunlight resistance, chemical resistance, toxicity and mixing. Plastic products enterprises should also master some basic knowledge when choosing color masterbatches. Next, Shunchuan Xiaobian will take you to understand how to solve the problem of precipitation of plastic masterbatch.

Precipitation problems also cause quality problems in the production of blown film and co-extruded film products. In the production of products, the proportion of raw materials is usually 70%LLDPE + 30%LDPE, and metallocene is added to improve the scratch resistance and puncture resistance of the film. In the selection of masterbatches, in addition to dispersion, compatibility, heat resistance and sun resistance, precipitation should also be considered. Problems in each link will affect the quality of the product. In particular, the production of vegetable packaging film, food packaging film, children's products packaging film, clothing film, sanitary napkins, diapers and other film materials, to avoid the appearance of color masterbatch is more important. In other words, the blown film production enterprise should master the masterbatch knowledge, avoid problems, and put forward reasonable requirements for the color masterbatch production enterprise.

We will continue to improve the competitiveness of the enterprise, further develop the friendly and cooperative relations with colleagues at home and abroad and friends from all walks of life, and jointly create a better tomorrow. Phase change, washing, drying and granulation. Only in this way can product quality be guaranteed. In addition, when grinding the pigment, a series of technical tests of the masterbatch should be carried out, such as measuring the fineness of the mortar, measuring the diffusion properties of the mortar, determining the solid content of the mortar, and determining the fineness of the mortar. Color base.

A color masterbatch usually consists of three parts. The colorant carrier dispersant is mixed by a high-speed mixer, crushed and extruded into particles. In the process of plastic processing, the masterbatch has the advantages of high concentration, good dispersion and high cleanliness.
