Describe

Fused epoxy powder outer coating is a new type of anti-corrosion layer developed in the past 30 years. It adopts electrostatic spraying technology to apply epoxy powder coating. It is suitable for oil pipelines, natural gas pipelines, heating pipelines and water supply pipelines. The working temperature is -30 ℃—100℃, one film formation.

The coating has the characteristics of simple coating operation, no pollution, good impact resistance and bending resistance of the coating, and high temperature resistance, and is widely used at home and abroad. With the economic development and the improvement of the quality of life requirements, people have stricter requirements on water quality, and they have paid more and more attention to sewage treatment and water recycling.

Salts and some chemicals in the water will corrode steel and concrete lining and PCCP concrete pipes. When CO32-, SO42- plasma and dissolved oxygen penetrate the steel surface, the steel is oxidized, and the volume expansion of the corrosion products causes the concrete to rupture, resulting in steel pipes, The cast pipe corroded, the concrete pipe cracked, and the water quality was contaminated.

In order to prevent corrosion, anti-corrosion coatings can be applied to the inner walls of steel pipes and concrete pipes. At present, the commonly used internal anti-corrosion materials at home and abroad mainly include epoxy resin and polyurethane resin coatings. The epoxy resin coating has particularly good salt and alkali resistance, can be attached to the alkaline surface of the concrete layer for a long time, and is the preferred coating for the anticorrosion and anti-seepage of the surface of the concrete layer. Donghua Company once applied epoxy paint to concrete test blocks and soaked it in saturated salt water for 23 years. It still has a bright appearance, strong adhesion and toughness.
