The manufacturing method
of matte powder
matte powder is an important raw material widely used in chemical production, especially in plastics, coatings, inks and other industries. The main function of matte powder is to give the surface of the product a soft, non-reflective matte effect. The following is the matte powder manufacturing method:

1. raw material preparation

manufacture matte powder main raw materials including polymer resin, filler and pigment. Among them, the polymer resin mainly plays the role of bonding and wrapping the pigment, the filler can increase the proportion and hardness of the matte powder, and the pigment determines the color of the matte powder.

2. pigment dispersion

add the pigment to a high-speed dispersing machine according to a certain proportion, add an appropriate amount of dispersant and water, and carry out high-speed dispersion. During the dispersion process, attention should be paid to controlling the dispersion speed and time to ensure that the pigment is fully dispersed and to avoid excessive dispersion leading to too fine pigment particles.

3. mixing pulping

mix the dispersed pigment slurry with polymer resin, filler and other raw materials according to a certain proportion, and add an appropriate amount of water to make a slurry with a certain viscosity. The mixing process needs to be fully stirred to ensure the uniform mixing of the raw materials.

4. spray drying

The mixed slurry is dried by a spray dryer to make a matte powder product. In the process of spray drying, it is necessary to control the drying temperature and air volume to ensure the quality and output of matte powder.

5. Sieving Packaging

The dried matte powder needs to be sieved to remove excessive particles and impurities, and then packaged to obtain the final matte powder product.

The above is the basic manufacturing method of matte powder, and the specific production process needs to be adjusted and optimized according to the requirements of the product. At the same time, in order to ensure the quality and stability of the matte powder, it is also necessary to strictly control the quality of the raw materials to ensure that the purity and particle size distribution of the raw materials meet the requirements.

In short, the manufacturing method of matte powder is not complicated, but it requires an in-depth understanding and mastery of the process and raw materials to produce high-quality and stable matte powder products.
