Description

technical field [0001] The invention belongs to the technical field of chemical production, in particular to a polyethylene cracking device. Background technique [0002] Polyethylene wax is a polyolefin synthetic wax. Its appearance is white or light yellow block, flake or powder solid. The relative molecular mass is 1000-4000. It has low toxicity, non-corrosiveness, high hardness and high softening point. , low melt viscosity, wear resistance, heat resistance, good lubricity, dispersion and fluidity, etc., can effectively improve the processing efficiency of PVC pipes, profiled materials, films, cables and other plastics and rubbers, and have broad prospects for development and utilization. At present, the production of polyethylene wax is mainly obtained through three methods: ethylene monomer oligomerization, polymer degradation (polyethylene cracking) and by-products in the polyethylene synthesis process. It is an industry with great market potential to prepare polyeth...

Problems solved by technology

However, on the one hand, the device does not stir the material uniformly, and on the other hand, the heating effect on the material is not good. In addition, the air is not removed when the material reacts to form polyethylene wax, which affects the reaction product.
