Problems solved by technology

The traditional "three-acid" chemical polishing solution contains a large amount of nitric acid, so a large amount of toxic NOx yellow smoke will be produced during the polishing process, which will seriously damage the health of workers, corrode equipment, pollute the atmosphere and reduce the life of the tank

Embodiment Construction

[0034] Now in conjunction with embodiment the present invention is described in further detail:

[0035] The smokeless polishing treatment solution for high-gloss aluminum profiles of the present invention is achieved by comprising H at a concentration of 85%. 3 PO 4 , with a concentration of 98% H 2 SO 4 , 30% concentration of hydrogen peroxide or potassium permanganate or perchloric acid or sodium molybdate or ammonium persulfate or sodium vanadate, cerium nitrate or sodium silicate, imidazoline or benzotriazole or phytic acid or thiourea , sodium dodecylbenzenesulfonate or sodium benzenesulfonate or sodium toluenesulfonate or sodium xylenesulfonate, nickel chloride or nickel sulfate or lead acetate, when the solution of the present invention is prepared, it needs to be fully stirred so that the solution is mixed evenly. The content of components is as shown in the table:

Abstract

The invention provides a smoke-free polishing treatment solution for a high-gloss aluminum sectional material and a use method thereof. The smoke-free polishing treatment solution is characterized by comprising 85% H3PO4, 98% H2SO4, 30% hydrogen peroxide or potassium permanganate or perchloric acid or sodium molybdate or ammonium persulfate or sodium vanadate, cerium nitrate or sodium silicate, imidazoline or benzotriazole or phytic acid or thiourea, sodium dodecyl benzene sulfonate or sodium benzene sulfonate or sodium toluene sulfonate or sodium xylene sulfonate, and nickel chloride or nickel sulfate or lead acetate. Compared with the prior art, the smoke-free polishing treatment solution provided by the invention has advantage of no generation of high-pollution NOx yellow smoke, and enables the surface of the aluminum sectional material to have excellent gloss and no pitting microscopic defects.

Description

technical field [0001] The invention relates to a polishing liquid and a using method thereof, in particular to a polishing liquid for aluminum profiles and a using method thereof. Background technique [0002] Due to its advantages of low density, high specific strength, easy processing and forming, castable, strengthenable, strong thermal and electrical conductivity, no low-temperature brittleness, non-magnetic, strong light and heat reflection, and nuclear radiation resistance, aluminum profiles are used in Automobiles, aerospace, architectural decoration, home appliances, instruments, computers, mobile phones, daily hardware and many other fields have become the second largest metal structural materials after steel. Since aluminum alloys are susceptible to mechanical damage during processing and forming, resulting in surface defects such as scratches and wear, in order to eliminate these surface defects during processing, mechanical polishing, chemical polishing or elec...
