What is a black special for pumping
05/15/2018
The colorant cannot react with the
resin and various additives, and has strong solvent resistance, low migration,
and good heat resistance. That is, the
masterbatch cannot participate in various chemical reactions. For example, carbon black can control
the curing reaction of polyester plastic, so carbon black cannot be added to
polyester. The dispersibility and coloring
power of the pigment should be good. When the dispersion of the
colorant is not uniform, the appearance performance of the product may be
affected; when the coloring power of the colorant is poor, the amount of the
colorant is increased and the material cost is increased. The
dispersibility and coloring power of the same colorant in different resins are
not the same, so this should be taken into account when selecting the colorant.
Should
understand the other properties of the color material, such as plastic products
used in food, children's toys, the requirements of color material should be
non-toxic; plastic products used in electrical appliances, should choose good
electrical insulating material; for outdoor plastic products, pigments with good weathering resistance should be selected.
The main products are:
1) Professional black masterbatch.
2)
Professional analysis: professional and technical personnel provide material
analysis for customers; solve technical problems and analyze chromatic
aberration.
Precautions for
masterbatch use:
A.
After the masterbatch is stored for a period of time, it will absorb moisture,
especially PET, ABS, PA, PC, etc., so it should be dried according to the same
process of the same color and achieve the moisture content.
B. Color matching with
masterbatch to achieve the desired color must be very careful, and often occur
in color and shade changes.
C, masterbatch and other additives
will react, use caution.
D, attention should be paid to the
selection of dilution ratio of masterbatch. If a high dilution ratio is used,
the production cost will be lower, but it will also be limited by the
processing equipment;
