How to remove the residue and dirt on the surface of 304 stainless steel plate
Leave a message
Residues and dirt adhere to the surface of 304 stainless steel plate, which seems difficult to solve. In fact, everyone wants to make a mistake. Here are different solutions for different residues in 304 stainless steel plate.
1. There is dust residue on the surface of 304 stainless steel plate
The manufacturing site is often covered with dust, and there is often a lot of dust in the air. They will fall on the surface of machinery and equipment again. They can be removed with tap water or alkaline solution. As everyone knows, adhesive stains can only be removed with high-pressure water or steam.
2. There are residues floating on the surface of 304 stainless steel plate
If it is impossible to completely remove the experimental saturated solution of antirust treatment, it is not recommended to apply this experimental method on the processing process surface of machinery and equipment, that is, the direct contact surface used to produce and manufacture people's daily necessities. A very simple experiment is to expose to water for 12-24 hours to check whether there is rust. This test is both sensitive and time-consuming. This is detection, not cleaning. If iron is found, the following organic chemical and photocatalytic methods must be used for removal.
3. There are paint, pencil, oily marker and other residues on the surface of 304 stainless steel plate
The interference of this pollutant is similar to that of vegetable oil. It is proposed to clean with neat soft bristle brush and neat water or acid cleaning solution, or high-pressure water or steam.
4. The surface of 304 stainless steel plate has residue and welding paste
Welding methods using flux include manual welding, flux cored arc welding and arc welding. This kind of electric welding will leave fine flux particles on the surface, which cannot be removed according to the general cleaning method. This kind of particulate matter will be the source of crevice corrosion. It is necessary to carry out mechanical equipment cleaning to eliminate residual flux.
