GB/T 2085.2-2019Aluminium powder—Part 2: Inflammable fine aluminium powder (English PDF)

Foreword

GB/T 2085 "aluminum powder" is divided into four parts.

---Part 1. Air atomized aluminum powder;

---Part 2. Ball milled aluminum powder;

--- Part 3. pulverizing aluminum powder;

--- Part 4. Nitrogen atomized aluminum powder.

This part is the second part of GB/T 2085.

This part is drafted in accordance with the rules given in GB/T 1.1-2009.

This part replaces GB/T 2085.2-2007 "Aluminum powder Part 2: Ball milled aluminum powder". This part is related to GB/T 2085.2-2007 In addition to the editorial changes, the main technical changes are as follows.

--- Added normative reference document YS/T 617.7 (see 2 and 4.1);

--- Added normative reference document SN/T 0370.3 (see 2 and 6.1.2);

---Added two products of FLQ1600 and FLQ850 (see 3.1.1, 3.1.1 of 2007 edition);

--- Revised Table 1, the grades and specific requirements are listed as Tables 1 and 2 (see Table 1, Table 2, Table 1 of the 2007 edition);

--- Modified the particle size distribution unit "particle size/µm" to "screen aperture/µm" (see 3.1.1, 3.1.1 of the 2007 edition);

--- Modified FLQ355B's oil content "1.0" to "0.7" (see 3.3, 2007 version 3.3);

--- Modified FLQ80A, FLQ56, FLQ45 grease content "3.8" to "3.55" (see 3.3, 2007 version of 3.3);

--- Increased chemical composition of Al2O3 requirements (see Table 3, Table 2 of the 2007 edition);

--- Increase the formula for the calculation of Al2O3 content (see 4.2.4);

--- Increase the relevant requirements for the export of dangerous goods packaging (see 6.1);

--- Added a comparison table between the brand name and the brand used (see Appendix A).
