Sintered epoxy powder, also known as thermosetting epoxy resin heavy anti-corrosion powder, is a solid material that uses air as a carrier to be transported and dispersed. It is applied to the surface of preheated steel products for melting, leveling and solidification. Form a uniform coating Anti-corrosion is a heavy anti-corrosion coating formed at high temperatures. The coating has the advantages of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance. Classification of sintered epoxy powder) according to the usage method can be divided into: powder for spraying inside the pipeline, powder for spraying outside the pipeline, and powder for general use inside and outside the pipeline. Powder for external spraying of pipelines is divided into: single-layer powder, double-layer powder, and three-layer structure anti-corrosion powder). According to the use, it can be divided into: powder for oil and gas pipelines, powder for drinking water pipelines, powder for fire protection pipelines, and anti-static powder for coal mines. Powder for ventilation pipes, chemical pipes, oil drill pipes, pipe fittings, ship pipes, high salt water heavy anti-corrosion pipes, etc. ) can be divided into two types according to curing conditions: rapid curing and ordinary curing. The curing conditions of fast-curing powders are generally ℃/.~ Mainly used for external spraying of pipelines or three-layer anti-corrosion structures. Due to the short curing time and high production efficiency, they are suitable for assembly line operations. The curing conditions of ordinary curing powders are generally ℃/above due to the long curing time. Good leveling and suitable for spraying in pipelines. The anti-corrosion methods of sintered epoxy powder mainly include: electrostatic spraying method, thermal spraying method, suction method, fluidized bed method, roller coating method, etc. In-pipe coating generally uses friction electrostatic spraying, suction method or thermal spraying. These spraying methods all have a common feature, that is, the workpiece needs to be preheated to a certain temperature before spraying so that the powder will melt as soon as it comes into contact. The residual heat should be able to The coating film continues to flow and is further leveled to cover the entire steel pipe surface, especially in the depressions on the steel pipe surface and on both sides of the weld. The molten coating flows in and fills the surface, making the coating closely combined with the steel pipe to minimize pores and solidifies within a specified time. Finally, it is cooled with water. Terminate the curing process. Welcome new and old customers to call us to discuss business
