1. The feature of the production line: This production line is mainly used for polyethylene and butyl rubber compound with anti-corrosion protection of the production. With the use of self-adhesive butyl rubber, artesian, good electrical insulation, air tightness, as well as high tensile strength polyethylene, to of petrochemicals, city sewage, water, gas and other anti-corrosion protection of steel pipes to ensure the validity period of 50 years. It can be used to substitute asphalt or epoxy anti-corrosion materials, so it can be regarded as the latest environment-friendly anti-corrosion material. The production line of plastic from the cut, pinch smelting, the refining, rolling compound, cooling, curly implementation of the pipeline operation, high degree of automation, low intensity, the production process environmental protection, clean and pollution-free. 2.
