HG / T 2879.4—1997
This standard is a test method standard. It is equivalent to the international standard ISO5795-1:1988 "Rubber Compounds-Clay" Part 1, Appendix F (Calculation of ratio). bZxz.net
Differences between this standard and Appendix F of ISO5795-1: This standard adds Chapter 1 Scope, Chapter 2 Reference Standards, and Chapter 5 Test Report.
This standard is proposed by the Technical Supervision Department of the Ministry of Chemical Industry of the People's Republic of China. This standard is under the jurisdiction of the Carbon Black Industry Research and Design Institute of the Ministry of Chemical Industry; this standard is drafted by the Carbon Black Industry Research and Design Institute of the Ministry of Chemical Industry; the main drafters of this standard are: Yu Lian, Hu Kaibi, Xue Lei, HG / T 2879. 4 -- 1997
Former ISO
ISO (International Organization for Standardization) is a worldwide joint organization of national standard bodies (ISO member bodies). The work of formulating international standards is usually carried out by ISO technical committees. Any member group interested in a profession for which a technical committee has been established has the right to participate in the committee. International organizations, governmental or non-governmental, that have ties with ISO may also participate in this work. In all electrical technical standards, ISO works closely with the International Electrotechnical Commission (IEC). Before an international standard is adopted by the ISO Council, the technical committee sends the draft international standard to each member group for voting. According to ISO requirements, it can only be formally passed if at least 75% of the member groups vote in favor. The international standard ISO5795-1 was developed by the ISO/TC45 Technical Committee for Standardization of Rubber and Rubber Products. The general standard ISO795 is titled Rubber Compounds - Rubber, which includes the following three parts. -Part 1: Test methods (non-rubber tests) -Part 2: Rubber tests
Part 3: Technical requirements
Appendices A to F are part of ISO 5795

1 Scope
1.1 This standard specifies the calculation method of natural clay
1.2 This standard is applicable to the calculation of natural clay for rubber compounding. It can also use the
ratio method, the calculation of
-ratio, and other industrial natural clays Sio
1.3 This standard is applicable to the calculation of natural clay Sio,
ratio that has been chemically treated with neutralizing acidic substances (such as amines) during the production process.
1.4 This standard does not apply to natural clay that has been surface modified (such as silane treatment). 1.5 This standard does not apply to natural clay that has been fired. 2 Referenced standards

The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standards will be revised. Parties using this standard should explore the possibility of using the latest versions of the following standards. HG/T2879.2—1997 Determination of aluminum content of rubber compound ceramics (cqVIS05795-~-1:1988) HG/T2879.3—1997 Determination of silicon content of rubber compound ceramics (eqvISO5795—1:1988) 3 Overview
The ratio is used to characterize the chemical composition of clay (hydrated silicon-aluminum compound). 3.1 Silicon (calculated as SiO2) is calculated according to the results of silicon (SiO2) in Chapter 8 of HG/T2879.3-1997, as the percentage of SiO2.
3.2 Aluminum (calculated as Ai0) is calculated according to the results of aluminum (Al2O) in Chapter 7 of HG/T2879.2-1997, as the percentage of A1O.
Approved by the Ministry of Chemical Industry of the People's Republic of China on April 21, 1997 and implemented on October 1, 1997
