The service life of polypropylene fiber anticorrosive tape

Polypropylene fiber anticorrosive tape is composed of three parts: base material, adhesive layer and anti-sticking release film. Its service life is manifested in the following aspects.

Substrate part: It is a plain woven fabric with UV-resistant polypropylene mesh reinforced fiber. The special process and material selection are very resistant to stress damage, can effectively resist external damage due to construction or other reasons, and are not aging in long-term exposure to the sun.

Adhesive layer part: The butyl rubber modified petroleum asphalt is used, and the viscoelasticity of the butyl rubber is mainly used to give the adhesive a strong sealing performance. Petroleum bitumen and auxiliary corrosion inhibitors and rust conversion agents stabilize the surface to be protected against corrosion.

Anti-stick release film part: With special isolation, the thick glue layer adhesive sticks to the back material due to the wet initial tack, which solves the problem of loose roll.

Polypropylene fiber anticorrosive tape has been in the country for 20 years and has been used in oil, natural gas, chemical and urban construction water supply and drainage, oil and gas, gas transportation steel pipelines and steel buried storage tanks in the fields of external anticorrosion and repair projects. It has been widely used in external corrosion protection of steel pipelines. This product has good impact resistance, high tensile strength, excellent bonding performance, good aging resistance, good UV resistance, etc., and is non-toxic and harmless to people. It has become the choice of pipeline anti-corrosion construction adhesive tape.

Polypropylene fiber anticorrosive tape performance test impact resistance 23N·m, UV resistance 600h> 8%, peel strength 36N/cm, water absorption rate 24h 0.20%, no corrosion on the surface after peeling off the anticorrosive layer, estimate the polypropylene fiber anticorrosive tape The anti-corrosion layer has a service life of up to 50 years.
