Can brown fused alumina be used to produce cookware?
Brown fused alumina is kind of artificial abrasive,main chemical:Al2O3, which takes about 95%.
Brown fused alumina can not be used to produce cookware directly,but it is used as blasting material to do surfact treatment of cookware.
Why brown fused alumina can be used to blasting cookware?
First, brown fused alumina has high hardness and high wear resistance. Its hardness reaches level 9, second only to diamond, which enables it to effectively remove stains and oxide layers on the surface of kitchenware during sandblasting, while maintaining its sharp edges to ensure the sandblasting effect . In addition, brown fused alumina has good toughness, is not easy to break, and can maintain stable cutting ability during sandblasting, further ensuring the sandblasting effect .
Secondly, brown fused alumina produces less dust during sandblasting. Due to its high specific gravity and large bulk density, brown fused alumina produces less dust during blasting, which helps protect the health and safety of operators and also reduces environmental pollution . This is very important for kitchenware sandblasting, because the reduction of dust can avoid affecting the health of operators.
Finally, brown fused alumina has good chemical stability. It has good stability to most chemicals at room temperature, is not easily corroded by corrosive agents such as acids and alkalis, and can maintain its appearance and physical properties unchanged for a long time . This enables brown corundum to maintain its stable performance in cookware sandblasting without causing damage to the surface of cookware.
