聚乙烯防腐胶粘带的防腐体系是由防腐带、保护带、补口带、底漆组合而成。胶粘带是由聚乙烯基膜，热复合上一层以丁基胶为主体的胶粘层，共挤压成的带状防腐材料。它具有绝缘性好、防腐效果优良、机械强度高、耐碰撞、耐老化、吸水率小、施工方便、安全卫生、应用范围广、使用寿命长等特点。广泛应用于石油、天然气、石油化工、电力、冶金、城市燃气管网、供水等各种管道工程与设施中金属管道的外防腐高效，长寿命. 广泛应用于石油化工、天然气煤炭等工程中埋地架空金属管道的外防腐。

Polyethylene anticorrosion adhesive tape is composed of inner wrap tape, outer wrap tape, joint wrap tape and primer. Adhesive tape is a kind of tape anticorrosion material formed by extruding polyethylene base membrane and one butyl rubber adhesive layer that is covered thermally on the former. So it possesses good insulation, excellent anticorrosive effect, high mechanical strength, collision resistance, aging resistance, small water absorption, convenient construction, safety& health, wide application and long lifetime etc. Polyethylene anticorrosion adhesive tape can be used extensively in metal pipes of all pipelines and facilities in petroleum, natural gas, petrochemical industry, electric power, metallurgy, urban gas pipeline network and water supply etc. for efficient and long lasting outer anticorrosion. Beside, it is also used in buried or overhead metal pipes of petrochemical industry, natural gas and coal etc. for outer anticorrosion.
