Embodiment 1
[0047] (1) Preparation
[0048] Select and use natural antigorite minerals (excluding olivine and chrysotile, and the composition of the atomic number ratio conforms to Si 5.8-6.2 [Mg 3.8-4.2 o 9.8-10.2 ](OH) 7.8-8.2 ) as a raw material, after it is roughly crushed by a jaw crusher, it is processed by a ball mill wet grinding method under stirring to obtain a fine powder.
[0049] Stir and mix 20kg of the obtained fine powder with 180kg of water and 10g of oleylamine in a vertical mixer for 120min to obtain an aqueous suspension. Then, utilize the GSDF50 cyclone (working pressure is 0.3MPa) to carry out cyclone classification treatment to this aqueous suspension and measure powder size on-line (BT-9300ST type laser particle size distribution analyzer), and collect the diameter in 3-18μm The overflow liquid of flake powder within the range of 20-24 and the flake diameter / thickness ratio in the range of 20-24. The obtained overflow liquid was dried (HB881-8 drying oven, 105...
Embodiment 2
[0057] (1) Preparation
[0058] Except that polyvinylpyrrolidone was used instead of oleylamine, metal fine polished antigorite powder was prepared by the same process as in Example 1, and the same detection and analysis as in Example 1 were carried out.
[0059] As a result, the resulting metal finely polished antigorite powder has the atomic ratio composition formula of Si 5.95 [Mg 4.05 o 10.05 ](OH) 7.95, the Mohs hardness is 4.0; and the morphology of the powder in the obtained metal finely polished antigorite powder is in the shape of a roughly cuboid sheet with a sheet diameter in the range of 3 to 15 μm and a sheet diameter / thickness ratio of 20 ~24 range.
[0060] (2) Application
[0061] Except using the 45# steel plate sample with the same size and its initial surface roughness is 90nm, the solid content of the metal fine polishing antigorite powder of the obtained metal fine polishing antigorite powder prepared by the same procedure as Example 1 is a polishing ...
Embodiment 3
[0063] (1) Preparation
[0064] Except that sodium dodecylbenzenesulfonate was used instead of oleylamine, metal fine polished antigorite powder was prepared by the same process as in Example 1, and the same detection and analysis as in Example 1 were carried out.
[0065] As a result, the resulting metal finely polished antigorite powder has the atomic ratio composition formula of Si 5.85 [Mg 4.15 o 10.15 ](OH) 7.92 , the Mohs hardness is 4.2; and the morphology of the powder in the obtained metal finely polished antigorite powder is in the shape of a roughly cuboid sheet with a sheet diameter in the range of 3 to 18 μm and a sheet diameter / thickness ratio of 22 -24 range.
[0066] (2) Application
[0067] Except using the GH1015 nickel alloy plate sample with the same size and its initial surface roughness as 42.3nm, the resulting metal finely polished antigorite powder had a solid content of 8.5% by mass prepared by the same procedure as in Example 1. liquid and perfo...
