Stainless steel is the material of many products, and some will be exposed to the outside, but after wind and sun, stainless steel products will still maintain the original quality. We have given us the following explanation about the atmospheric corrosion resistance of stainless steel.
Experience has shown that the degree of atmospheric corrosion varies from region to region. For ease of explanation, it is recommended to divide the area into four categories, namely rural, urban, industrial and coastal areas.
The countryside is basically a pollution-free area. The population density in this area is low, with only pollution-free industries.
The city is a typical residential area, commercial area, and light industrial area with light traffic pollution.
Industrial zones have caused serious air pollution in heavy industry. Stainless steel filter manufacturers claim that the pollution may be caused by fuel gases, such as sulfur and nitrogen oxides, or other gases released by chemical plants or processing plants. Particles suspended in the air, such as dust or iron oxide deposited during steel production, can also increase corrosion.
Coastal areas usually refer to areas within one mile of the coast. However, the ocean atmosphere can go deep inland, especially on islands. The prevailing wind comes from the ocean and the weather is bad. For example, the climatic conditions in the UK are such that the entire country belongs to the coastal area. If wind and sea fog mix together, especially the salt accumulation caused by evaporation, the stainless steel filter manufacturer claims that there is little rain and it is not often washed by rain, and the conditions in coastal areas will be even more unfavorable. If there is industrial pollution, it will be more corrosive.
Studies in the United States, Britain, France, Italy, Sweden and Australia have confirmed the influence of these areas on the corrosion resistance of various stainless steels. These contents are briefly introduced in NiIDI's "Architect's Reading", which can help designers choose the best cost-effective stainless steel for various fields.
When choosing, it is important to determine whether there are local factors that affect site usage. For example, stainless steel is used under factory chimneys and near air-conditioning exhaust baffles or waste yards.
But how to clean the surface of the oil?
Oil pollution, if the main component of oil pollution is oil and other oil pollution, stainless steel filter manufacturers claim that gasoline and diesel can be removed, but pay attention to safety, because gasoline is flammable.
If it is other oil pollution, you want to know what kind of oil it is, but the general principle of cleaning oil pollution is to use a similar molecular structure, or to be mutually soluble. In fact, cleaning is to remove the oil in the cleaning fluid that can be removed. As long as we know this, this is a good choice. It can also be cleaned with gasoline cleaning agent or cleaning agent
