Metal supplies (stainless steel tableware, guardrails, doors and windows, etc.) are processed by sandblasting abrasives to appear bright, Henan Sicheng Xiaobian for everyone to analyze: sandblasting white corundum abrasive on stainless steel material processing requirements.
Stainless steel surface and abrasive processing requirements:
1. Stainless steel surface processing requirements
1. Surface cleanliness grade P1 and surface cleanliness class Sa2.5;
2. Ensure that the workpiece is smooth, dense, neat, and free of cold lines and pores;
3. The relative humidity is ≤ 60%, and the surface temperature of the stainless steel plate is at least 5 °C higher than the dew point temperature;
4. The roughness is between 40~75μm, and the soluble salt ≤ 30mgm2&40; equivalent to sodium chloride&41;;
5. Check whether the workpiece itself has defects, such as gaps, bubbles, pores, cracks and other defects. The quality of the casting itself is unqualified, and white corundum abrasives cannot be used for polishing
Requirements for stainless steel sandblasted abrasives:
1. The abrasive is clean, hard and angular;
2. Test the pH value of the abrasive with pH test strip;
3. Abrasive quality should be recognized.
