Readily dispersible not only affects color strength and shade, but also because of poor dispersion uneven coloring, producing streaks or color point of impact colored appearance, more seriously affect the mechanical properties of the finished coloring. Pigment having good dispersibility can get an ideal of the brilliant, sales brightness, fertilizers, colorants, transparent plastic products, therefore, readily dispersible pigment for coloring plastics is important. Pigment used in chemical fiber spinning, which is easily dispersed more important to good or bad. In the melt spinning process due to stress how much, they have frequent replacement of filters, fertilizer colorants companies, waste of materials and labor, so that equipment downtime is too long. More serious cause production can not be normal. The main factors affecting the colorant coloring effect: the coloring effect of food coloring coloring agents how, affected by many factors, the price of fertilizer colorant, the main factors are as follows: Pigment is not soluble in common solvents, coloring agents, so to get a good color performance, the need to use mechanical means pigment uniformly dispersed in the plastic. Inorganic pigments thermal stability, excellent light stability, fertilizer colorants, low prices, but relatively poor color strength and relative density; high organic pigment tinting strength, bright color, chromatography complete, relative density, the disadvantage of heat resistance, weather resistance and hiding as good as inorganic pigments. Fertilizer colorants _ _ Weifang Fuyuan colorant fertilizer company by the Environmental Protection Technology Co., Ltd. Weifang Fuyuan.
