Epoxy Anti-Corrosion Powder Coating for Coal Mine Gas Drainage Pipes

Surface Finish Options Overview

Představení produktu:

This product is formulated using phenolic epoxy resin and incorporates self-developed conductive polymers and conductive materials, combining the advantages of intrinsic and doped conductivity. It is specifically designed for conductive heavy-duty anti-corrosion powder coatings. The surface resistivity of the coating can reach below 10⁵ Ω, effectively eliminating static electricity accumulation in gas drainage pipes and preventing static sparks, thereby enhancing safety. The coating features high reactivity, strong adhesion, high cross-link density, and excellent resistance to chemicals, solvents, cathodic disbondment, as well as superior flexibility and impact resistance.

Opatření:

The steel pipe surface should be free of oil and moisture; the surface treatment quality should reach Sa2 1/2 level (GB/T 8923); the anchor pattern depth should be 40-90 mm; dust and abrasives on the steel pipe surface should be blown clean. Preheating temperature should be controlled between 180-250°C and must not exceed 275°C.

The product should be stored in a well-ventilated, dry indoor environment with a temperature below 30°C, away from heat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure. The stacking height should not exceed four layers. Avoid long-term pressure and ensure the packaging box is sealed to prevent caking and moisture, which can affect fluidization performance.

To ensure thorough curing of the epoxy coating and better anti-corrosion performance, it is recommended to preheat the steel pipe surface to above 200°C to improve the curing completion rate.
