Polyvinyl chloride (PVC) anti-corrosion tape 
 Product technology and use: 
 Polyvinyl chloride (PVC) tape with PVC anti-corrosion resin, plasticizer, stabilizer and other additives, with the extrusion method of forming rolling pipe obtained film to the substrate, the thermal compound with the first high-pressure process that small based rubber compound in the above, the polyvinyl chloride (PVC) has good mechanical properties and corrosion resistance and low prices make polyvinyl chloride (PVC) has a good anti-corrosion tape prospect! 
 Polyvinyl chloride (PVC) tape is mainly used for the corrosion products are mainly used for corrosion of buried steel pipe insulation and protection layer, or for cable winding corrosion and other different uses. 
 Second, the main features: 
 1. Good physical and mechanical properties. 
 2. Tightness, electrical insulation. 
 3. Acid, alkali, salt, oil, chemical media performance. 
 4. Good flame retardant, mildew performance and good weather resistance.

 Usage: 
 (1) rust, except welds, burrs, oil, dirt and dry. Hand and the rust should be up to St3 level, mechanical descaling should be consistent with SYJ 4 0 0 7-8 6 of Sa2 level. 
 (2) primer (manual or mechanical) 
 (3) when the primer is dry to wrapping, wrapping should meet the requirements of the coating level and structure. 
 (4) spark can pass the inspection under the ditch fill. 

 Fourth, during the transportation: 
 (1) tape in the transport process of anti-exposure, anti-rain, to prevent crush deformation. 
 (3) should be negative 凉, temperature 5 ~ 30 ℃, temperature <75 ℃ warehouse storage, for 6 months, and away from heat and flame.
