Brushed black masterbatches
Preparation method of brushed black masterbatches
The general preparation of black masterbatch includes two methods: physical coloring and chemical coloring.
Physical coloring
Physical color mixing is mainly the black pigment and polymer mixed together, and at high temperature melt mixing, and then through the stretching, shearing and other processes, the mixture will be pressed into black masterbatch. This method is easy to control the color and density changes, but it requires the use of high-temperature melting equipment and is easily affected by temperature and machine equipment.
Chemical color mixing
Chemical color mixing uses a chemical reaction to create black pigments that are blended with a polymer to form a brushed black masterbatch. This method produces a more stable masterbatch with a lower concentration of iron ions and a more uniform color. Moreover, this method does not need high temperature equipment, but the control requirements for reaction conditions are higher, and its process complexity is larger.
Third, the application of drawing black color masterbatches
Electronic and electrical appliances
Brushed black masterbatch is widely used in electrical products such as wires and cables, plugs and sockets, televisions, power tools, etc. It can make the products have better tensile strength and wear resistance.
Construction field
Brushed black masterbatch is suitable for the manufacture of water pipelines, sanitary facilities, garden facilities and other various construction materials, which can improve the durability and aesthetics of the material.
Chemical products
Brushed black masterbatches are suitable for manufacturing various acid and alkali tanks, chemical containers, etc. Its excellent chemical resistance and high temperature stability make chemical products more safe and reliable.
Automobile parts
Brushed black masterbatches are ideal for manufacturing automotive parts, such as automotive pipelines, door and window seals, hoods, doors, etc. They can enhance the durability, strength, and high temperature resistance of the products.
