Why are more and more masterbatches used in plastics production?

  Now more and more technology, including production equipment, the current production equipment with various protection devices, plastic feeding devices have more air delivery equipment, when feeding, the powder is relatively blown away, so the pigment is mostly used The color of the parent material. In addition to this, there are the following points:

    1. The plastic masterbatch gives the pigment a better dispersibility in the product: the color masterbatch is an aggregate obtained by uniformly loading a super-constant pigment into the resin. In the production process of the color masterbatch, the pigment must be refined to improve the dispersibility and tinting strength of the pigment. The carrier of the special color masterbatch has the same plasticity as the product, and has good matching property, and the pigment particles can be well dispersed in the product plastic after heating and melting.

    2. The plastic masterbatch is beneficial to maintain the chemical stability of the pigment: if the pigment is directly used, the pigment will absorb water and oxidize due to the direct contact of the pigment during storage and use, and after the color masterbatch, the resin carrier By separating the pigment from air and moisture, the quality of the pigment can be kept constant for a long time.

 3. The plastic masterbatch ensures 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 mixing with the resin is relatively uniform, so the amount of addition can be ensured. Stable, thus ensuring the stability of the color of the product.

 4. Plastic masterbatch protects the health of the operator: the pigment is generally powdery, easy to fly when added and mixed, and will affect the health of the operator when inhaled by the body.

 5. The plastic masterbatch keeps the environment clean and does not stain the vessel:

 6. The plastic masterbatch process is simple, easy to change color, save time and raw materials: since the pigment directly contacts the air during storage and use, moisture absorption, oxidation, agglomeration, etc. will occur, and the direct use will be on the surface of the plastic product. The color point appears, the hue is dark, the color is easy to fade, and it causes dust to fly when mixed, which affects the health of the operator. The masterbatch is mechanically processed in the production process, and the pigment is refined, and the pigment and the resin carrier and the dispersing agent are thoroughly mixed to separate the pigment from the air and moisture, thereby enhancing the weather resistance of the pigment and improving the pigment. The dispersibility and tinting strength of the pigment, the hue is bright. Since the masterbatch is similar in shape to the resin particles, it is more convenient and accurate in metering, and does not adhere to the container during mixing, thereby saving time for cleaning the container and the machine and raw materials used for cleaning.
