What is a composite PE tape?
Application prospect and measures: composite polyethylene anticorrosive tape is a kind of important anti-corrosion materials, steel pipe anticorrosion is widely used in petroleum, chemical, natural gas, water supply, city gas, power and other industries. How do you use anticorrosive tape? Earlier, some key domestic projects, large diameter pipelines and long-distance pipelines have been using imported products. Now polyethylene tape can be replaced completely, the application prospect is very wide, and the social and economic benefits are considerable.
Main technical specifications of adhesive tape1. Tensile strength >20MPa; patch >15MPa2, elongation at break is >200%, >300%3, peel strength >20N/cm; to coating primer steel plate >5~10N/cm; to back material >5~10N/cm4. Electrical strength >3MV/m5, water absorption rate <0. 03%Main technical specifications of primer1, table dry time 1~5min2, viscosity 10~15s
The successful development of composite polyethylene anticorrosive adhesive tape, bubble phenomenon reform coating tape degumming and anti-corrosion layer, avoids the phenomenon of environmental pollution in the production process, ensure product durability and coating service life, greatly improve the impact performance of the product of the peel strength, mechanical strength and anticorrosion layer the product not only has excellent anti-corrosion, insulation performance, convenient construction and operation, safety and sanitation, the comprehensive economic cost is low. The product fills the gap of domestic polyethylene anticorrosive tape production, product quality has reached the international advanced level.
