This section GB/T 17850 Part 7.
This section drafted in accordance with GB/T 1.1-2009 given rules.
This section uses the translation method identical with ISO 11126-7.1995 "before coating the steel surface treatment jet cleaning non-metallic grinding
Technical requirements for the material Part 7. Fused alumina. "
The documents of our country that are consistent with the corresponding international documents that are normative references in this section are as follows.
GB/T 17849-1999 steel coating before coating the surface treatment of jet cleaning non-metallic abrasive test method (eqv
ISO 11127.1993).

Surface coating of steel before coating
Technical requirements for non-metallic abrasive blasting
Part 7. Fused alumina
Warning --- Equipment, materials and abrasives used for surface treatment may be dangerous if used carelessly. Many countries are right
Materials and abrasives that are considered hazardous during, after use, or after use (waste management), such as free silicon, carcinogens or toxic substances, are regulated
set. Therefore, these rules should be observed. It is important to ensure that appropriate guidance and all required precautions are implemented.
1 Scope
GB/T 17850 provisions of this part of jet-cleaning fused alumina abrasive particle size range, apparent density, Mohs hardness,
Water content, electrical conductivity of water leachate and water-soluble chloride content.
The requirements specified in this section applies only to unused abrasive, does not apply to used abrasive.
Test methods for jet cleaning non-metallic abrasives are given in the various sections of ISO 11127.
Note 1. The commonly referenced standards for non-metallic abrasives in the world are given in Appendix A.
Note 2. Although this part of GB/T 17850 is developed to meet the requirements of steel surface treatment, but also applies to the use of jet cleaning technology to deal with other
The surface or part of the material. These rules are given in ISO 8504-2.20001) "Coating of steel surface treatment before the second part of the surface treatment methods
Minutes. Abrasive jet cleaning "is given.
