GH400 coal tar epoxy anticorrosive wrapping cold | cold wrapping tape 
 Product technology and use: 
 This product is finalized by the base-band and glue the two parts. Enhanced baseband use synthetic - polypropylene nonwoven substrate impregnated with coal tar epoxy glue made by the de-oiling; stereotypes solvent-free epoxy adhesive used coal tar from the A, B and paired double-mixing 
 Our products are widely used in petroleum, chemical, power, urban water utilities and other industries, gas, natural gas, heating and other steel pipes and steel pipe corrosion or the appearance of tank rehabilitation works. Is a province of work, effort against the cold without heating process heating energy-saving environmental protection products, anti-corrosion system, it is the best economic choice.

 Third, use: 
 (1) Surface treatment: rust, except welds, burrs, oil, dirt and dry. Hand and the rust should be up to St3 level, mechanical descaling should be consistent with the Sa2 SYJ4007 -86 level. 
 (2) plastic coated stereotypes: the A and B were finalized 1:1 mixture of rubber, mixing evenly, brushing, coating uniformity requirements, full, can not leak Tu 
 (3) wound baseband: shape plastic coated wound immediately after the baseband, you must maintain the shape of plastic adhesive state, if it takes too long been stereotyped gum brushing hard work, you must then be wrapped with brushing again, after a good base-band wrapped around then cover it again that stereotypes stereotypes plastic plastic plastic stereotypes → → baseband. 
 (4) construction must achieve a well-ventilated conditions, away from open flame. 
 Fourth, during the transportation: 
 (1) transport should be light light disposal to prevent rain, avoid sun exposure. 
 (2) Store in a cool, dry, ventilated and not near the fire source, the biggest barrier placed 4th floor, storage period of six months
