Of course, the application of the sentry box is outside, but outside, there will inevitably be various kinds of scratches or stains, for this kind of stain, how should we deal with it? First, the scratch integrated booth manufacturers say that the booth in order to prevent the process lubricant or product, dirt accumulation, mechanical cleaning of stainless steel booth scratches and other rough surfaces is required. TREATMENT: We can add grinding or manual grinding leveling technology to solve Oh. Rust spots are sometimes seen on the products or equipment of the Shanghai stainless steel box before or during the production process, which indicates that the surface is seriously contaminated. TREATMENT: The rust must be removed before the equipment is put into use. Thoroughly cleaned surfaces should be tested by iron or water tests. 3. Oil and grease organic substances such as oil, grease, and even fingerprints can be sources of localized corrosion. As these substances can act as barriers, they can affect the chemical and electrochemical cleaning effect, so must be completely removed. When the adhesive tape and protective paper are removed, a part of the adhesive will remain on the surface of the stainless steel. Treatment: 1, when the whole adhesive has not hardened, we can use organic flux to remove. 2. When the whole adhesive is used for a long time, it will form a hardened adhesive and form a corrosion source of crevice corrosion. In this case, we need to use fine abrasives for mechanical cleaning, which may require a lot of manpower and material resources. Fifth, the location of the dust booth will usually have dust, often with a lot of dust in the air, they constantly fall on the surface of the booth. Like the Public Security Post, traffic post, community post, police post, such often in a high flow of places post, it is easy to be contaminated by dust. TREATMENT: We can use water or alkaline solution to remove the dust falling on the surface of the booth.
