Thick plastic polyethylene anticorrosive adhesive tape
Instructions for Thick Plastic Polyethylene Pipe Anticorrosive Adhesive Tape
1. Purpose and characteristics:
The special thick rubber anticorrosive tape for oil transportation is a new type of anticorrosive cold-wrapped tape masterpiece developed on the basis of the traditional thin polyethylene anticorrosive tape. The base material is a high- and low-density synthetic polyethylene film, and the adhesive layer is a high-viscosity thermoplastic modified butyl self-adhesive anticorrosive adhesive, supplemented by a layer of anti-stick isolation film. It can be widely used in oil, natural gas, chemical, urban construction, water supply and drainage, oil and gas, gas transportation steel pipelines and external anti-corrosion and repair projects of steel buried storage tanks. It is a newest pollution-free and harmless environmentally friendly anti-corrosion material. Compared with traditional anti-corrosion adhesive tape, it has the following advantages: 1. It has strong viscosity and can realize self-fusion, waterproof, air permeability and good sealing. 2. High electrical insulation, excellent anti-aging stability, strong anti-ultraviolet radiation ability. 3. It has the ability to resist soil stress damage and strong impact resistance. 4. Single-layer winding of the tape can achieve the normal or reinforced anti-corrosion required by the SY/T0414-2017 standard. The traditional tape needs to be wound in multiple layers, which reduces the impact of human factors on the quality of anti-corrosion during the anti-corrosion operation, and reduces the construction cost. 5. The construction is simple, fast, no curing time, manual or mechanical operation is possible, shortening the construction period. 6. Low cost, no pollution and three wastes. The thick rubber polyethylene anticorrosive tape has been certified by the national professional inspection, and its indicators are much higher than the requirements of the SY/T0414-2017 standard. It fully meets the American ANSI/AWWAC209-00 and NACEMR0274-95 indicators. It is currently the most economical and The most environmentally friendly products have high promotion and application value.
