The production process of color masterbatch mainly includes the following steps:

Preparation of raw materials. Select appropriate pigment particles according to the production color requirements, which can be natural or synthetic materials, and choose appropriate diluents to dilute the pigment particles to the appropriate concentration. one

Pigment treatment. Process the selected pigment particles, including crushing, grinding, and screening, to crush pigment particles, mix pigments and diluents, remove unqualified pigment particles, and ensure pigment quality.

Dilute the pigment. Mix the processed pigment particles with the diluent, stir and mix them to make the pigment particles evenly dispersed in the diluent, and adjust the concentration of the pigment to meet the product requirements.

Granulation. Mix the diluted pigment particles with the carrier resin, and extrude or spray them through an extruder or injection molding machine to form a molten granular material, which is the color masterbatch. twenty-three thousand four hundred and fifty-six

Cooling and screening. The color masterbatch particles need to be cooled to room temperature to prevent further melting. The cooled color masterbatch also needs to be screened through screening equipment to separate particles of different sizes, ensuring product quality and uniformity. twenty-six

Packaging. According to customer needs, the graded color masterbatch is packaged using plastic bags, woven bags, or cardboard boxes. During the packaging process, attention should be paid to sealing and protection to prevent the color masterbatch from getting damp or being contaminated by external factors. four hundred and seventy-eight

Quality inspection. Conduct quality inspections on the produced masterbatch products, including testing of color stability, pigment concentration, particle size, and other indicators, to ensure that the products meet quality requirements.

The entire production process requires strict control of parameters such as temperature, stirring speed, and mixing ratio at each stage to ensure stable quality of the color masterbatch. The production process flow of masterbatch
