Foreword

GB/T 18838 "Technical Requirements for Metal Abrasives for Blast Cleaning of Steel Surface Treatment before Coating" is divided into the following parts. ---Part 1.Guidelines and Classification; ---Part 2.Chilled iron sand; ---Part 3.High carbon cast steel shot and sand; ---Part 4.Low-carbon cast steel shot; ---Part 5.Steel wire section. This part is Part 4 of GB/T 18838. This part is equivalent to ISO 11124-4..1993 "Technical requirements for metal abrasives for blast cleaning of steel surface treatment before coating Part 4.Low Carbon Cast Steel Shot" (English version). This part is equivalent to translation ISO 11124-4..1993. For ease of use, this section has made the following editorial changes. --- "This International Standard" is changed to "This Part"; --- Use a decimal point "." to replace the comma "," as a decimal point; ---Use a comma "," instead of a comma ","; ---Added the title of Table 2; ---The foreword of the international standard is deleted. Appendix A and Appendix B of this section are informative appendices. This part was proposed by China State Shipbuilding Corporation. This part is under the jurisdiction of the National Coatings and Pigments Standardization Technical Committee before painting metal surface treatment and painting process technical subcommittee.

GB/T 18838.4-2008/ISO 11124-4..1993 Steel surface treatment before coating Technical requirements for metal abrasives for blast cleaning Part 4.Low carbon cast steel shot Warning. The abrasives, materials and equipment used for surface treatment may be dangerous if used carelessly. Many countries are using During or after use (waste management), materials and abrasives considered hazardous, such as free silicon, carcinogens or toxic substances, are regulated. Therefore, these regulations should be followed. It is important to ensure that proper guidance is given and all required precautions are implemented.

1 scope

This part of GB/T 18838 specifies the technical requirements for 12 grades of low carbon cast steel shot abrasives for blast cleaning, including hardness, Density, defects and structural requirements, chemical composition, etc. The requirements specified in this part of GB/T 18838 only apply to unused abrasives, not to used abrasives. For the test methods of metal abrasives for blast cleaning, see the various parts of GB/T 1981. Low-carbon cast steel shots are recyclable and reusable abrasives, which can be used for both fixed and on-site injection equipment. Note 1.Refer to Appendix A and Appendix B for the world standards of metal abrasives commonly referred to and their relationship with this section. Note 2.Although this part of GB/T 18838 is specially formulated to meet the surface treatment requirements of steel structures, the specified characteristics are generally applicable to Surfaces or parts of other materials treated with blast cleaning technology. These requirements have been in ISO 8504-2.2001) "The surface of steel before coating Surface treatment methods Part 2.Abrasive Blast Cleaning is given in.
