An anti-corrosion wrapping coating for threaded manual valves

Abstract

The invention discloses an anti-corrosion wrapping coating for a threaded manual valve, which belongs to the field of valve anti-corrosion. An anti-corrosion wrapping coating for a threaded manual valve includes a threaded valve. Layers include primer coating, heavy anti-corrosion layer, lotus leaf self-cleaning coating, inner self-cleaning coating, outer waterproof self-cleaning layer, primer coating, heavy anti-corrosion layer, lotus leaf self-cleaning coating, inner self-cleaning coating, outer waterproofing The self-cleaning layer is applied on the surface of threaded valves from left to right in turn, which can improve the waterproofness and oil resistance of the anti-corrosion coating, making the anti-corrosion coating not easy to peel off, and making the corrosion resistance of the valve reach remarkable At the same time, through the use of self-healing materials, the anti-corrosion coating has the ability of self-healing when cracks or holes are first formed, which greatly prolongs the effective time of the anti-corrosion coating and makes the internal threaded valve extended service life.

Description

technical field [0001] The invention relates to the field of anti-corrosion valves, in particular to an anti-corrosion wrapping coating for threaded manual valves. Background technique [0002] The threaded valve body has internal threaded threaded thread or external threaded threaded threaded thread, which is connected with the threaded threaded thread of the pipeline, which can be used to control air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid flow. The threaded valve body has an internal or external threaded threaded thread, which is connected with the pipeline threaded threaded thread; the main materials of the threaded valve are forged steel, stainless steel, and cast steel; the general maximum working pressure is 1.6-32MPA, and the working temperature is - 20°C-455°C, the valve diameter is from DN10-DN50. [0003] The anti-corrosion coating is a functional coating that is made of various high-performan...

AI Technical Summary

Problems solved by technology

[0004] There are generally many corners on the surface of the valve. Some threaded valves used for water saving are often exposed to water. Long-term contact with water makes the anti-corrosion coating on the surface of the valve, especially the coating at the corners, easily corroded and cracked. Even if there are holes, if the cracks are not repaired in time, the cracks and holes will become larger and larger, which will cause the anti-corrosion coating to peel and fall off, making its anti-corrosion ability worse, and making the use of threaded valves in the coating more difficult.
