Epoxy coal pitch cold-wound tape is an updated product of the epoxy coal pitch glass cloth anti-corrosion layer. It is a patented product independently developed by Tiejia Brand. Patent number: ZL 93 2 21420.7. This product consists of two parts: a base tape and a styling glue. The base tape is a polypropylene non-woven fabric soaked in epoxy base material glue, replacing the alkali- and wax-containing glass fiber cloth. The styling glue is a solvent-free epoxy coal tar paint, which replaces the solvent. Type epoxy coal pitch coating.
Epoxy coal pitch cold-wound tape is a type of anti-corrosion cold-wrap tape. It has been used in domestic anti-corrosion projects since the mid-1990s. The entire anti-corrosion protection system is composed of base tape and styling glue. . Because it is mostly used for the anti-corrosion of the outer walls of steel pipes in oil, gas, water supply, drainage and heating industries such as petroleum, natural gas, chemical industry, electric power, urban construction and other industries, it does not require heating when used, so it is also called: epoxy coal pitch pipeline anti-corrosion cold-wrapped tape . In recent years, it has also been well used in waterproofing and anti-penetration treatment of concrete sewage pools, roofs, and floors in industry and civil construction. The base material of the epoxy coal pitch cold-wound tape (base tape) we produce is made of reinforced synthetic fiber polypropylene non-woven fabric (felt), which is impregnated with epoxy coal pitch base material glue and then deoiled; the styling glue is made of quick-drying non-woven fabrics. Solvent epoxy coating is mixed by A and B before use. In order to better adapt to the ambient temperature conditions during construction, two types of setting glue, normal temperature type and low temperature type, are specially formulated. Product features: Anti-corrosion cold-wound tape has uniform base material thickness, no needle holes, high mechanical strength and good corrosion resistance; complete specifications, suitable for all types of projects. The styling glue is non-volatile, fast to film, has good flexibility, adhesion and anti-corrosion capabilities, does not absorb water, and resists water vapor penetration. The anti-corrosion layer formed by the effective combination of base tape and styling glue has strong bonding, smooth surface, high hardness, impact resistance, no delamination, no peeling, no leakage points, voltage resistance, wide temperature range, no shrinkage, no cracking, Acid and alkali resistant, excellent anti-corrosion protection.
