Manufacturing Method of Matte Powder
Matte powder is an important raw material widely used in the production of chemicals, especially in the plastics, coatings and ink industries. The main function of matte powder is to give the product surface a soft, non-reflective matte effect. The following is the manufacturing method of matte powder:
I. Preparation of raw materials
The main raw materials for the manufacture of matte powder include polymer resins, fillers and pigments. Among them, polymer resin mainly plays the role of bonding and wrapping pigment, filler can increase the specific gravity and hardness of matte powder, and pigment determines the color of matte powder.
Two, pigment dispersion
Pigment will be added to the high-speed disperser according to a certain proportion, add the appropriate amount of dispersant and water, and carry out high-speed dispersion. In the process of dispersion, it is necessary to pay attention to the control of dispersion speed and time to ensure that the pigment is fully dispersed, and to avoid over-dispersion resulting in too fine pigment particles. Third, mixing slurry
Mix the dispersed pigment slurry with polymer resin, filler and other raw materials according to a certain proportion, add appropriate amount of water to make slurry with a certain viscosity. The mixing process needs to be fully stirred to ensure the uniform mixing of raw materials. Fourth, spray drying
will be mixed slurry through the spray dryer for drying, made of matte powder finished products. Spray drying process needs to pay attention to control the drying temperature and air volume to ensure the quality and yield of matte powder. V. Sieving and Packaging
The dried matte powder needs to be sieved to remove oversized particles and impurities, and then packaged to get the final matte powder product.
The above is the basic manufacturing method of matte powder, the specific production process also needs to be adjusted and optimized according to the requirements of the product process. At the same time, in order to ensure the quality and stability of matte powder, it is also necessary to carry out strict quality control of raw materials to ensure that the purity of raw materials and particle size distribution and other indicators meet the requirements.
In short, the manufacturing method of matte powder is not complicated, but it requires in-depth understanding and mastery of the process and raw materials in order to manufacture high-quality, stable matte powder products.
