The main factors affecting the coloring effect of coloring agent: coloring effect of coloring agents to food coloring, is affected by many factors, the main factors are as follows: the pigment is not soluble in common solvents colorant tribasic ammonium colorant guaranteed, so to obtain the desired The coloring property, need mechanically pigment uniformly dispersed in the plastic. Inorganic pigments thermal stability, excellent light stability ammonium phosphate colorants, low prices, but relatively poor coloring coloring ammonium phosphate company, the relative density; high organic pigment tinting strength, bright color, chromatography complete, the relative density disadvantages as heat resistance, weather resistance and hiding power as good as inorganic pigments. Easy dispersion not only affects the coloring strength and shade, but also because of poor dispersion uneven coloring, producing streaks or color dots coloring affect the appearance of ammonium phosphate colorants sales, more seriously affect the mechanical properties of the finished coloring. Good dispersion of pigment can be an ideal brilliant degree, brightness, transparency plastic products, therefore, easily dispersible pigments for coloring plastics is important. Pigments used in chemical fiber spinning, its ease of dispersion is more important to good and bad. In the melt spinning process due to how much pressure, had frequent replacement of the filter, wasting a lot of materials and labor, the equipment downtime is too long. Lead to more serious production can not be normal.
