PVC plastic is currently a very common material, in life many products are made of PVC plastic, pvc plastic seen in life is colorful, which is added in the production process with a certain colorant, and at the same time can have more products according to the performance of PVC plastic. Today, Hengtong Chemical Pigment Xiaobian will introduce in detail "PVC plastic common colorants, what are the properties?" ”
First, PVC plastic common colorants
The colorants used in PVC plastics are mainly organic pigments and inorganic pigments. PVC plastics have higher requirements for pigments, such as high temperature resistance during processing, not affected by HCL, no migration during processing, light resistance, etc. Commonly used are:
1. Red is mainly soluble azo pigments, cadmium red inorganic pigments, iron oxide red pigments, phthalocyanine red, etc.;
2, yellow mainly chrome yellow, cadmium yellow and fluorescent yellow;
3, blue color is mainly phthalocyanine blue
4, green is mainly phthalocyanine green;
5, white mainly with titanium dioxide;
6, purple is mainly plastic purple RL;
7, black is mainly carbon black. In addition, fluorescent brighteners are used for whitening, gold powder and silver powder are used for color printing, and pearlescent powder makes plastics have pearl-like astigmatism.
Second, what are the properties of PVC plastics
PVC is widely used in the building materials industry because PVC has very unique performance characteristics. PVC has the characteristics of rainproof, fireproof, antistatic, easy to form, it also has high light resistance and fire resistance. It has the characteristics of flame retardant and is widely used in fire prevention.
PVC has a variety of appearances, it not only has a simple process and excellent performance, it can also show natural colors and people want colors, can show the richness of color.
PVC is completely non-toxic and tasteless, has no harm to the human body, and is an environmentally friendly material. It can protect the ecological environment, so it is the trend of the development of social civilization. PVC materials meet the needs of the building materials industry and have become the perfect home products for environmental protection and practicality.
In addition, the price of PVC flooring is relatively low, so it is very popular in the material market, and at present, China's improvement technology in PVC has reached the international advanced level.
