Warning. For the surface treatment used equipment, materials and abrasive, if not careful, may be hazardous. Many countries in the use of
During or after use (waste management) that the presence of hazardous materials and abrasives such as. free silicon, carcinogenic or toxic substances, provisions are made.
Therefore, compliance with these requirements. It is important to ensure that appropriate guidance be given and all precautions required to be implemented.
1 Scope
GB/T 17850 provisions of this part of the special steel slag sand blast - cleaning abrasive particle size range, the apparent density, Mohs hard
