ISOForeword
IS(International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The formulation of international standards is usually carried out by ISO technical committees. Each member body has the right to participate in the committee if it is interested in the subject of a technical committee. Official or unofficial international organizations associated with ISO may also participate in this work. ISO and the International Electrotechnical Commission (TEC) work closely in all aspects of electrotechnical standardization. The draft international standards adopted by the technical committees are sent to the member groups for voting. At least 75% of the member groups participating in the voting must vote in favor before they can be published as international standards. ISO) 11126-3 was formulated by ISO/TC35/SC12 Paints and Varnishes Technical Committee, Subcommittee on Surface Treatment of Steel before Coating.

This standard adopts the following definitions
Copper refining slag copper relincry slag is a synthetic mineral-
non-metallic abrasive for blast cleaning, made from slag obtained from copper smelting, granulated in water, dried, screened, with or without mechanical crushing. Its main component is iron silicate. 4 Marking

1) According to the agreement between the supply and demand parties, abrasives of different sizes can be combined, and the cumulative proportion of large and small abrasives in normal sizes should be specified in detail. The maximum particle size should not exceed 3.15mm and the percentage of particles less than 0.2mm should not exceed 5% (by weight). The marking example of the refining slag is:
The initial particle shape is sand particles, and the particle size range is 0.5mm~~1.0mm. The marking of copper refining slag is: N/Cu/G 0.5--1.0.
5 Requirements
5.1 General requirements
5.1.1 Copper refining slag should be a glassy amorphous material that does not absorb water and can only be wetted on the surface. 5.1.2 The silicon in the copper refining slag should exist in the form of bonded magnetic salts. The content of free silicon (such as quartz, quartz, and quartz) determined by X-ray diffraction method should not exceed 1% (by weight). 5.1.3 The material should be free of corrosive components or contaminants that are harmful to adhesion. Note: 1. The liquid abrasives are supplied predominantly in an angular state. More rounded particles are also not excluded, as their effect on surface sugar content is similar to that of cleaning with angular particles. The equipment, materials and solutions used for surface treatment may cause harm to personnel and environment if not used carefully (such as partial separation of vinegar). The toxic substances that cause the toxic substances are>. In the implementation of this standard, the relevant national pollution and environmental protection policies and regulations shall be observed, and the quality of the products shall be properly protected.
