2. The base material of the cold-rolled strip is polypropylene non-woven felt, which is a new type of synthetic fiber with high mechanical strength, good corrosion resistance and no wax on the surface, so the surface of the anti-corrosion layer is flat, closely combined, with few pinholes, and has excellent electrical and anti-corrosion properties.
3. The cured adhesive is solvent-free, quick-drying and fast-curing coating. According to the season, it can be divided into three types: normal temperature type, low temperature type and ultra-low temperature type, so it can be constructed normally all year round, alleviating the construction problems in winter.
4. The construction is convenient and quick, and it can reach the thickness and electric spark leakage detection voltage required by China's national standard GB50268-97 "Code for Construction and Acceptance of Water Supply and Drainage Pipeline Engineering", China petrochemical industry standard SH3022-99 "Technical Specification for Corrosion Protection of Petrochemical Equipment and Pipelines" and China petroleum and natural gas industry standard SY/T0447-96 "Technical Standard for Epoxy Coal Tar Anticorrosive Coatings for Buried Steel Pipelines" at one time.
