Description

Technical Field

[0001] This utility model belongs to the field of granulation equipment technology, and more specifically, it relates to a bimodal flame-retardant polyethylene plastic granulator. Background Technology

[0002] The manufacturing method of polyethylene granulators mentions that polyethylene processing generally employs a low-temperature, high-activity initiator polymerization system, using high-purity ethylene as the main raw material and propylene / propane as density modifiers. The polymerization reaction is carried out at approximately 200℃–330℃ and 150–300 MPa to produce molten polyethylene. After water cooling, the molten polyethylene is fed into a granulator for pelletizing. However, existing polyethylene granulators have some problems. For example, after water cooling, a layer of water droplets covers the surface of the molten polyethylene and enters the granulator with it. When the cutter cuts the polyethylene, these water droplets remain on the cutter surface, creating adhesion and causing the cut polyethylene pellets to stick to the cutter. The technical background of bimodal flame-retardant polyethylene plastic granulators involves the processing principle of polyethylene materials, the characteristics of bimodal flame-retardant polyethylene, and how to overcome the problems of existing granulators. These factors collectively determine the design and manufacturing requirements of the granulator to ensure efficient and stable production of high-quality flame-retardant polyethylene pellets.

[0003] Based on the above, existing equipment is a single-line device. Due to the stickiness of its materials, it is easy for the machinery to be damaged. This means that once the equipment malfunctions, production must be stopped. Therefore, a multi-line production device is particularly important. Utility Model Content
