How to clean the stains on the surface of the Stainless Steel Wedge Wire Screen
2019-12-25 By zhaozhao
Stainless steel wedge wire screens are made of various materials, generally low carbon steel and stainless steel filter plates. They can also be made of other metal materials and non-metal materials.
The surface of the stainless steel wedge wire screen is dusty and easy to remove. You can use soap, weak detergent or warm water to wash the rust caused by the dirt on the surface of the stainless steel sieve. You can use 10% nitric acid or abrasive detergent to clean it or use special Washing chemicals for washing. The surface of the stainless steel screen panel is attached with bleaching agents and various acids. Rinse immediately with water, dip with ammonium solution or neutral carbonated soda water solution, and wash with neutral detergent or warm water.
Since the relative thickness of the blank of the stainless steel wedge wire screen used for stamping is very small and the resistance to instability under the action of compressive stress is also very poor, it is difficult to be in a free state without the instability resistance device (such as blank holding) Smoothly complete the stamping process. The elongation-type stamping process, which is dominated by tensile stress, is more than the compression-type process, which is dominated by compressive stress. The value of the pressure per unit area perpendicular to the direction of the plate surface is not sufficient enough to plastically deform the plate in the direction of the plate surface.
Because the value of the pressure per unit area in the direction perpendicular to the plate surface is much smaller than the internal stress in the plate surface direction, most of the screen panel stamping deformation can be approximately treated as a plane stress state to analyze its deformation mechanics. And the calculation of process parameters has been greatly simplified.
