Question:

What are the processing methods of black masterbatch and what is more prominent than other plastic raw materials?

What are the processing methods of black masterbatch and what is more prominent than other plastic raw materials?

Answer:

In the dyeing of plastic products, black masterbatch only 0.6%-0.8%, it will be extremely black, and no more will not be more dark. According to the experimental data show that the product in Xinjiang area for outdoor use, such as the need to rely on black masterbatch anti aging, as long as the use of high-quality black masterbatch (rather than return material as carrier, oil wetting, dispersion of calcium carbonate and so on it), content of carbon black in the products reached 2-2.5%, namely: every 100 kilograms of raw materials, there is a 5-6 (the weight of 40%) containing carbon black masterbatch, the role played by far more than any anti aging products, product life can reach more than 10 years. That's why drip irrigation products, water delivery products, communications cable products are all black.
Double screw method, using mixing machine materials after mixing by twin screw extruder braces or granulation water, double screw mixing machine itself due to limited capacity, the general concentration of 25-32% in carbon black masterbatch. Mixing method, using mixing machine, mixing the material, adding mixer, kneading, and then feeding machine into the twin-screw extruder, water ring or underwater cut, masterbatch, general carbon black concentration of 40-45%.
In addition, carbon black has a special contribution to the strength of products and the enhancement of conductivity. There are three types of information plates available in the Fu plastics website: single screw, double screw, and dense. Single screw method, using mixing machine materials after mixing by single screw extruder brace granulation, the carbon concentration in the general 18-20%, production process backward, poor environmental conditions, is eliminated by process, do not rule out some fledgling small factories still use the method of processing.
