Standard aluminum bearing polishing solution formula

Abstract

The invention relates to a standard aluminum bearing polishing solution formula which is characterized by comprising the following ingredients in parts by weight: 100-200 parts of zirconia polishing powder, 100-200 parts of zirconium carbonate powder, 0.5-2 parts of monopotassium phosphate, 3-5 parts of a dispersant, 0.5-2 parts of glycerin, 0.05-0.5 part of a water-based defoamer, 5-20 parts of propylene glycol, 2-5 parts of methyl silicone oil, 10-30 parts of oleyl hydroxyethyl imidazoline, 800-1200 parts of deionized water, 102-136 parts of phosphoric acid, 36.7-73.4 parts of sulfuric acid,0.3-3 parts of aluminium ions, 0.5-4 parts of sodium dodecyl benzene sulfonate, 0.5-4 parts of sodium alcohol ether sulphate and 0.1-4 parts of sodium molybdate. In the formula, through the synergy of the phosphoric acid, the sulfuric acid, the aluminium ions, sodium dodecyl benzene sulfonate, sodium alcohol ether sulphate and sodium molybdate, the problem of aluminium material overetching can beeffectively avoided, and better polishing effect and higher polishing efficiency can be ensured. Meanwhile, the standard aluminum bearing polishing solution formula is smaller in harm to human body and environment.

Description

technical field [0001] The invention relates to the field of polishing liquid, in particular to a standard aluminum bearing polishing liquid formula. Background technique [0002] At present, aluminum alloy products, as one of the most important alloys in alloy materials, are more and more widely used in various industries. For example, 7 series aluminum alloys mainly include Al-Zn-Mg-Cu aluminum alloys. Different from ordinary aluminum, zinc is the main alloying element of 7-series aluminum. Adding a little copper and magnesium can make the material heat-treated and achieve very high-strength properties. Its hardness is close to that of steel and has good wear resistance. , Strong corrosion resistance. Due to the excellent properties of 7-series aluminum, it is mainly used in aerospace fixtures, trucks, tower buildings, ships, pipelines and other architectural applications that require strength. Such as: aircraft parts, gears and shafts, fuse parts, instrument shafts and ...

AI Technical Summary

Problems solved by technology

[0004] First of all, when the traditional three-acid chemical polishing solution containing nitric acid or the two-acid chemical polishing solution without nitric acid is used for chemical polishing operation on 7 series aluminum materials, it is difficult to obtain a bright and smooth surface, and over-corrosion often occurs. Problem, the overall polishing effect is poor

[0005] Secondly, although the mechanical polishing method can be used to obtain a brighter surface, there are still defects in the existing mechanical polishing technology, and the metal aluminum powder dust generated in the mechanical polishing process seriously endangers the health of workers; the production of mechanical polishing Low efficiency, high labor cost, high input cost of production equipment
