The history and craftsmanship of the masterbatch is like? Masterbatch Western European countries in the 1960s, first developed a late start in China in the late 1970s, Beijing, Shanghai and Tianjin to begin development and pilot production; mid-1980s, Beijing Yanshan Petrochemical wet and dry process technology and equipment imported from companies such as Ciba-Geigy, Hoechst succession and Guangdong Xinhui, China's masterbatch industry has entered a period of rapid growth. Masterbatch very strict technical requirements, the masterbatch technology generally use a wet process. Masterbatch materials by water phase grinding, phase inversion, washing, drying, granulation made, the only such product quality can be guaranteed. Further the pigment in the polishing process at the same time, should be carried out a series of masterbatches were detected, such as measuring the fineness of a sand slurry, determination of the diffusion properties of a sand slurry, sanding slurry solids content was measured and the measurement of the colorant fineness projects. |
