Waste PE cable pelletizer recycling modified method
Time:2022-03-01
Why do we need to recycling PE cable pelletizer?
High-density polyethylene cable is very difficult due to chemical cross-linking, upgrade production and processing, today high-density polyethylene is mostly used to heat dissolved refinery, but the environmental pollution is more serious, so refinery is banned, high-density polyethylene by my country Recycling into a big difficult point in China’s plastic recycling.
Chemical cross-linking PE is due to chemical crosslinked molecular formula measuring mesh tissue, cannot be pulverized and melted, and the recovery of pulverized chemical crosslinking PE is less forming production and processing due to low fluidity. The method maintained in the paper, the chemical cross-linking PE cable pelletizer recycling modification production pipe fittings have a special type of liquidity in the basic HDPE tube raw material, and the tensile strength is high by HDPE pipe, and the tensile strength is also in line with the requirements, and the overall advantages Even a new material. So PE cable pelletizer recycling is very important.
Waste chemical cross-linking PE wire cable recycled modified production of pipe fittings, involved in the upgrade of plastic, made by the following active ingredients: recovered chemical cross-linking PE cable broken sheet, PE hollow blow molded article crushed sheet 30-50 Net weight, LDPE blown film regeneration particulate matter 5-20 net weight, POE3-10 parts by weight, calcium stearate 0.1-0.3 Net weight, and its PE wax 0.2-1 Net weight.
Waste chemical cross-linking PE cable pelletizer recycled and modified materials,
1. the recovered chemical cross-linking PE cable crushed sheet and the PE hollow blow molded sheet (broken fragment size is 4-7mm) clean-up;
2. Take other raw materials and chemical cross-linking PE cable broken sheets, and the PE hollow blow molded sheet is placed together in the high mixing machine, and the time is 3-5 min.
3. the mixed material is made according to the single screw wire and PE cable pelletizer, the server’s speed ratio is 30, and the squeezing temperature of the rod is 165-200 ° C.
4. dry the particulate.
Chemical cross-linking PE cable waste plastics, due to chemical cross-linking, molecular network, melting production and processing is very difficult, at this stage, many large-scale medium-sized PE pipelines in the sales market will be low, and everyone will increase low fluid chemical crosslinking PE and The fluidity is not bad, the hollow blow molded PE material mixing and production, improved the fluidity of high-density polyethylene, reducing the fluidity of the hollow blow molded product PE, the two types of fused modified plastic fluidity just achieve large and medium-sized The pipe member PE produces processing fluidity, taking into account the comparative and comprehensive energy, everyone will increase 2 two-component phase solubility, improve the ductility, and the PE improvement, and use Stealate covered in Shanghai, foreign country, and is a good actual effect.
