Fiber (Polypropylene/Polyester) Master Batch compounding pelletizing line
Equipment configuration description for black Polypropylene/Polyester Master Batch
Polyester Master Batch and Polypropylene Master Batch mainly are black master batch, mainly used in textile filaments and short fibers. The optimal choice of equipment is GWH high performance 4-flight reciprocating kneader to ensure the uniformity of dispersion and distribution of carbon black. In particular, the extrusion temperature of the polyester masterbatch in production can be effectively controlled to avoid the brittleness of the finished product after overheating. The large groove deep structure of the reciprocating kneader screw effectively ensures the accurate feeding of the carbon black powder. The special mixing principle fully ensures the uniform distribution of carbon black in the resin. The flexible low-temperature mixing principle effectively controls the extrusion temperature of the material, so that the material reaches a certain tensile strength, and to produce medium and high-end polyester masterbatch and polypropylene masterbatch.

Equipment configuration description for Color Polypropylene/Polyester Master Batch
The optimal choice of equipment for Color Polyester and Polypropylene Master Batch is GWH high performance 4-flight reciprocating kneader. Due to the variety of colors for color fiber masterbatch, and the output per batch is low, so the GWH series reciprocating kneader should use GWH-58 and GWH-85 reciprocating kneader. During the production process, the equipment needs to be cleaned when changing batches. The most difficult thing to clean is the cleaning of the feeder. Some pigments are attached to the surface of the feeder and cannot be erased. Only can use alcohol etc the medium to clean. The newly developed feeder that can be quickly disassembled and cleaned on site , the feeder that all in contact with the materials are made of stainless steel, and the time for disassembly and reassembly is less than 10 minutes.
