CaCO3 Filler Masterbatch How To Choose Pigment Problems Sep 14, 2017

CaCO3 Filler Masterbatch how to choose pigment problems
 CaCO3 Filler Masterbatch coloring
  CaCO3 Filler Masterbatch Coloring is the most commonly used plastic coloring method today. The colorant dispersed in the carrier, with the CaCO3 Filler Masterbatch color resin simple mixed for the manufacture of plastic products. CaCO3 Filler Masterbatch Mixing the color resin with the colorant and granulating it into colored plastic for the molding process. Dry powder coloring: the powdery colorant and color resin evenly mixed directly after the manufacture of plastic products.
  CaCO3 Filler Masterbatch pigment selection
  Different functions CaCO3 Filler Masterbatch, in the selection of paint, the performance is different, the following were introduced under the CaCO3 Filler Masterbatch how to choose the pigment:
  Heat-resistant CaCO3 Filler Masterbatch selected pigments, the most basic requirements of the polypropylene fiber production process can withstand the temperature, to maintain its performance stability. Temperature temperature is generally required for more than 270 ~ 280 ℃.
Dispersible CaCO3 Filler Masterbatch Pigments should be excellent in dispersibility and are evenly dispersed in CaCO3 Filler Masterbatch, and the dispersants used will not degrade the quality of the polypropylene fibers, otherwise it will not produce good quality stained fibers and are not stable , It is easy to break or produce abnormal fibers when drawing fibers.
  Brightness Polypropylene liquid coloring has a variety of uses, which are used for bedspreads and knitted fabrics, requiring bright colors, because organic pigments are bright and bright, and easy to color, so that the use of organic pigments for the use of the above.
  Lightfastness Under the action of light, some pigments have a photosensitive effect, so that the coloring fiber fades and brittle, and the light resistance of the pigment is basically related to its chemical structure, so in the production of CaCO3 Filler Masterbatch should pay full attention to the light resistance of light, light Of the pigment need to be used, you can consider adding UV absorbers.
CaCO3 Filler Masterbatch on the use of CaCO3 Filler Masterbatch is a certain requirement, the following and we look at CaCO3 Filler Masterbatch CaCO3 Filler Masterbatch choose the main point of it!
(1) should understand the other properties of CaCO3 Filler Masterbatch, such as for the use of food, children's toys on the plastic products, require CaCO3 Filler Masterbatch should be non-toxic; for electrical appliances in plastic products, should choose good electrical insulation CaCO3 Filler Masterbatch; for outdoor plastic products, should choose good weather aging performance CaCO3 Filler Masterbatch and so on.
  (2) CaCO3 Filler Masterbatch dispersion, coloring should be good. CaCO3 Filler Masterbatch uneven dispersion, will affect the appearance of the product performance; CaCO3 Filler Masterbatch tinting force difference, will make CaCO3 Filler Masterbatch dosage increases, the material cost. The same CaCO3 Filler Masterbatch in different resins in the dispersion and color strength is not the same, so in the choice of CaCO3 Filler Masterbatch should pay attention to this point; CaCO3 Filler Masterbatch particle size and dispersion are also related, CaCO3 Filler Masterbatch particle size is smaller, then The better the dispersion, the color strength is also strong.
  (3) CaCO3 Filler Masterbatch can not react with resin and various additives, solvent resistance, small mobility, good heat resistance and so on. In other words, CaCO3 Filler Masterbatch can not participate in a variety of chemical reactions. If the carbon black can control the curing of polyester plastic, it can not be added in the polyester carbon black CaCO3 Filler Masterbatch; due to plastic molding process temperature is high, so CaCO3 Filler Masterbatch should be in the molding heating temperature conditions do not disassemble discoloration, the general Inorganic pigments have better heat resistance and poor heat resistance of organic pigments and dyes, which should be given sufficient attention when selecting CaCO3 Filler Masterbatch varieties.
