Sandblasting white corundum abrasives play a key role in our lives, just like the metal products around us (stainless steel tableware, guardrails, doors and windows, etc.) are processed brightly by sandblasting
Stainless steel surface and abrasive processing requirements:
1. Stainless steel surface processing requirements
1. Surface cleanliness grade P1 and surface cleanliness grade Sa2.5;
2. Ensure that the workpiece is smooth, dense, neat, without 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 concentration is between 40~75μm, 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 the white corundum abrasive cannot be used for polishing
Stainless steel sandblasting abrasive requirements:
1. The abrasive is clean, hard, and angular;
2. Use pH test paper to test the pH value of the abrasive;
3. The quality of abrasives should be recognized.
