By using a stainless steel wire mesh, we know that the stainless steel wire mesh itself contains the composition of stainless steel. Moreover, stainless steel is the advantage of corrosion resistance and durability. Therefore, stainless steel wire mesh has been widely favored by people, and it is also widely used in the petroleum industry as a mud net, chemical chemical fiber industry, as a sieve screen and electroplating. However, there are more people to use, and there are various problems due to lack of in-depth understanding. Here we will teach you how to solve it.
1, dust
Production is often done in dusty areas, often with a lot of dust in the air, which constantly land on the surface of the equipment. They can be removed with water or an alkaline solution. However, adhering dust requires high pressure water or steam for cleaning.
2, rust spots
In the process of using stainless steel wire mesh, stainless steel products or equipment are sometimes rusted before or during the production process, which indicates that the surface is seriously polluted. The rust must be removed before the equipment is put into use. The thoroughly cleaned surface should be inspected by iron test and/or water test.
3, flux
The welding process using flux is manual welding, flux core arc welding and submerged arc welding. These welding processes leave fine flux particles on the surface, which cannot be removed by ordinary cleaning methods. This particle will be the source of corrosion for crevice corrosion and must be removed by mechanical cleaning.
4, welding splash
Welding spatter has a lot to do with the welding process. For example: GTAM (gas shielded tungsten arc welding) or TIG (inert gas shielded tungsten soldering) does not splash. However, the use of GMAW (gas-shielded metal arc welding) and FCAW (arc welding with flux core) welding process can cause a lot of splash if the welding parameters are used improperly. When this happens, the parameters must be adjusted. If you want to solve the problem of welding spatter, apply anti-splash agent on each side of the joint before welding, which can eliminate the adhesion of spatter. This anti-splash agent and various spatters can be easily removed after soldering without damaging the surface or causing minor damage.
5, residual adhesive
During the use of the stainless steel wire mesh, when the tape and the protective paper are torn off, a part of the adhesive remains on the stainless steel surface. If the adhesive is not yet hard, it can be removed with an organic flux. However, when exposed to light and air, the binder becomes hard and forms a source of corrosion for crevice corrosion. Mechanical cleaning is then required with fine abrasives.
