In the process of making a product, there are many factors that affect the quality of the finished product, whether it is the machinery or the things we eat, or the things we usually use in our daily life. Naturally, our master color is the same, in the process there will be many factors affecting its quality, today we will understand what factors affect the quality of the black mother?

 

First, dispersion: Raw carbon black is a very difficult and dirty mixture, it is covered with dust, light weight, fluffy. Unless large-scale treatment measures are adopted, it will dirty machines and workers and make the working environment dirty.

 

Second, rheology: if a color masterbatch itself has good dispersion, but it can not flow into the material to be molded, the production effect is not ideal. In general, the primer resin used to produce masterbatches has a high rheological property. To save costs, some masterbatch producers use reused materials, scrap or recycled materials as resin carriers.

 

Compatibility: If the masterbatch is produced using chips or recycled materials, it may contain contaminants or other non-meltable polymers. This will cause some unpredictable, difficult to restrain trouble, waste the consumer's time and materials. At this time, the primer resin can be used to produce high-quality masterbatches, and the masterbatch has good compatibility during the melting process. Masterbatches can be produced using LLDPE, LDPE, HDPE, PP, PS, SAN, PA and other materials.

 

Fourth, stability: In today's international economy, it is necessary for international customers to have high requirements for the quality of the masterbatch and the stability of the raw material, which is also the fifth factor determining the quality of the black masterbatch. One of the main manifestations of stability is the steady carbon black ratio. If the percentage of carbon black is fluctuating, then the number of masterbatches that need to be melted is not the same, and it is impossible to produce the same hue of the product.

 

Covering power: This factor is particularly important for masterbatches used in waste or recycled polymers, where the role of black is to cover other colors in the waste. The coloring ability of large particle carbon black is poor, and it is not easy to cover all the other colors in the lower layer, and the result is that the product only gets the deviated color. During the melting process, the ability to correctly select carbon black with high coloring power to cover the existing color is called coverage power.

 

Six, color brightness: there are various types of carbon black on the market can be used for color masterbatch coloring, but all kinds of color and price are also very different. Large particle carbon black has lower coloration and different background color than small particle carbon black.
