The nature and use
of black pulp in the field of chemical production raw materials
1. Introduction

Black pulp as an important chemical production raw materials, widely used in plastics, rubber, coatings, inks, paper and other fields. Due to its unique properties and functions, black pulp has become an indispensable component in many products. This article will detail the properties and uses of black pulp.

2. the properties of black pulp

1. color and tinting strength

the main properties of black pulp is its color and tinting strength. It presents a deep black, with high hiding power and tinting power, can give the product a deep black.

2. Stability

black pulp has good thermal stability and light stability, and can maintain its color under high temperature and light conditions, so it is suitable for various processing conditions.

3. Dispersibility

black pulp has good dispersibility in water and organic solvents, and can be uniformly dispersed in the system to form a stable suspension.

4. Compatibility

black pulp has good compatibility with a variety of resins, rubbers, coatings and other substrates, and can be mixed with these materials to improve product performance.

3. the use of black pulp

1.

of the plastic industry In the plastic industry, black pulp is widely used as a colorant in the production of various black plastic products, such as pipes, profiles, sheets, etc. By adding black pulp, the weather resistance, UV resistance and thermal stability of the plastic can be improved.

2. Rubber industry

In the rubber industry, black pulp is used to produce black rubber products, such as tires, hoses, tapes, etc. The addition of black pulp can improve the wear resistance, aging resistance and color stability of rubber products.

3. Coatings Industry

In the coatings industry, black paste is used as a pigment in the production of black coatings, such as architectural coatings, automotive paints, etc. The addition of black paste can increase the hiding power, weather resistance and color stability of the coating.

4. Ink industry

In the ink industry, black paste is used to produce black inks, such as printing inks, screen printing inks, etc. By adding black paste, the tinting strength and printing effect of the ink can be improved.

5. Paper Industry

In the paper industry, black pulp is used as a pigment to produce black paper or paperboard. By adding black pulp, the blackness of the paper can be increased, and the color stability and weather resistance of the paper can be improved.

4. conclusion

In short, black pulp as an important raw material for chemical production has been widely used in many fields, such as plastics, rubber, coatings, printing ink, paper and so on. Due to its unique properties and functions, black pulp has become an indispensable component in many products. With the continuous development of science and technology, the performance and use of black pulp will continue to be expanded and optimized, which will play a greater role in the production and quality improvement of various industries.
