In the above, the above explanation of the constant temperature and humidity experimental box compressor valve is very important for the compressor, once the corrosion occurs, it will hinder the normal operation of the machine, and the heavy will cause the valve to rust and scrap. Therefore, anti-corrosion treatment measures for compressor valves are very necessary. Before we explained the addition of corrosion inhibitors and the use of non-metallic materials to inhibit corrosion, then what other methods are not mentioned?
3. Control the corrosive environment
The so-called environment, there are two broad and narrow senses, the generalized environment refers to the environment around the valve installation and its internal circulation medium; the narrow environment refers to the conditions around the valve installation. Most environments are uncontrollable and production processes are not subject to change. Only when there is no damage to the product or process, the method of controlling the environment, such as boiler water deoxidation and the pH of the alkali in the refining process, can be used. From this point of view, the above-mentioned addition of corrosion inhibitors, electrochemical protection, etc. are also controlled corrosion environments.
4, metal surface treatment
Metal surface treatment processes include sleeping plating, surface penetration, surface oxidation passivation, and the like. Its purpose is to improve the corrosion resistance of metals and improve the mechanical capabilities of metals.
5, spray coating method
Coating is the most widely used anti-corrosion method, and it is an indispensable anti-corrosion material and identification mark on compressor valve products. Coatings are also non-metallic materials. They are usually made of synthetic resin, rubber slurry, vegetable oil, solvent, etc., covering the metal surface, insulating the medium and the atmosphere to achieve anti-corrosion purposes.
Rug artificial grass is amongst the safest and most durable outdoor synthetic lawn surfaces available. Artificial turf is ideal for artificial playground grass. With children`s safety and product durability as our main goals, we select artificial turf for its soft and forgiving feel and resilience under the stress of heavy-duty-all-weather use, protecting your children from impact injuries. Artificial rug grass flooring material is safer than sod, wood chips, sand and even urethane surfaces. If child safety is important to you, then the rug artificial grass flooring is the obvious choice for your turf playground application.
