The use of masterbatch has the following advantages:
1. Better pigment dispersion in the product:
Masterbatch is an aggregate made by uniformly loading an ultra-constant amount of pigment into a resin.
In
the production process of masterbatch, the pigment must be refined to
improve the dispersibility and coloring power of the pigment. The carrier of the special color masterbatch is the same as the
plastic type of the product, and it has a good matchability. After
heating and melting, the pigment particles can be well dispersed in the
plastic of the product.
2. It helps to maintain the chemical stability of pigments:
When
the pigment is used directly, the pigment will undergo water absorption
and oxidation during the storage and use of the pigment. When the color
masterbatch is prepared, the resin carrier separates the pigment from
the air and water, and the quality of the pigment can be prevented for a
long period of time.
3 to ensure the stability of the color of the product:
The masterbatch particles are similar to the resin particles and
are more convenient and accurate in metering. They do not adhere to the
container during mixing, and the mixture with the resin is also uniform.
Therefore, it is possible to ensure the stability of the additive
amount, thereby ensuring the stability of the product color.
4. Protect the health of operators:
Pigments are generally powdery, and are easy to fly when added and
mixed. Inhalation by the human body will affect the health of
operators.
5. Keep the environment clean and uncontaminated:
6. The process is simple, easy to change color, save time and raw materials
