Metal Anticorrosive Treatment Methods
We should all understand that iron rust will cause red patches-iron oxide. Most of them appear on iron products that have not been cleaned. For this reason, various stainless steel products have emerged to deal with the problem of iron rust, such as stainless steel kitchenware, stainless steel washbasins, and so on. In fact, this is a measure for anticorrosion.
1. Can stainless steel not rust?
At the same time that more and more stainless steel products are being produced, the question of whether stainless steel is really anticorrosive is also being widely discussed. Finally, after repeated tests, it was found that "no rust for stainless steel " requires specific environments and requirements:
The corrosion resistance of stainless steel depends on how many alloy elements it contains;
Different environments also require different alloys of stainless steel;
It depends on how long the stainless steel environment needs to be stored.
As a member of the metal family, stainless steel, although it already has a certain degree of anti-corrosion ability, will eventually face the "fate" of being corroded. Then the "treatment" facing other members of the metal family can be imagined!
2. How much economic loss will corrosion bring?
Around the 1970s, many developed industrial countries did a systematic survey on the problem of metal corrosion. According to the survey report of industrial developed countries, the losses caused by metal corrosion accounted for 1% to 5% of the national GNP. In the following 30 years, people began to carry out various anticorrosive treatments on metals, did different degrees of protection and conducted a metal corrosion investigation again. The results show that different treatments for metal corrosion cause different losses. Among them, one thing is certain-the loss of metal without anti-corrosion treatment is much higher than that of anti-corrosion metal.
3. What are the metal anticorrosive methods?
In order to effectively solve the problem of metal anticorrosion, many methods have been researched, such as the commonly used structural change method, protective layer method, electrochemical protection method, and the like.
4. Testing of metal anticorrosive coatings
It is also very important to know the measurement of the metal surface coating thickness. If the metal surface coating thickness is too thick or too thin, it will directly affect the metal anticorrosive performance and service life. Generally, the the metal surface coating thickness can be measured by using a coating thickness meter. The accuracy of the three coating thickness meters independently developed by Linshang Technology is consistent with the accuracy of the international coating thickness meter brand Q-nix. It is currently the highest precision coating thickness meter.
