Example Embodiment

Specific embodiment one:

[0019] A polishing method for aluminum products, comprising the following steps:

[0020] Step 1, prepare chemical polishing liquid, in parts by weight: including brightener, corrosion inhibitor, phosphoric acid, sulfuric acid, characterized in that: in parts by weight: brightener 6, corrosion inhibitor 11, phosphoric acid 50, sulfuric acid 33 , made into 100 parts, the brightener is composed of 1-4 butynediol and glycerol, and the corrosion inhibitor is composed of phytic acid and polyphosphoric acid. The content of 1-4 butynediol in the brightener is 50% (weight ratio), and the content of glycerin is 50% (weight ratio). The content of phytic acid in the corrosion inhibitor is 50% (weight ratio), and the content of polyphosphoric acid is 50% (weight ratio). The concentration of the phosphoric acid was 85% and the concentration of the sulfuric acid was 98%. The concentration of the phytic acid was 50%, the concentration of the polyphosphoric acid w...

Abstract

The invention discloses an aluminium product polishing method. The method is characterized by comprising the following steps: I, preparing a chemical polishing solution comprising 3-12 parts of brightening agent, 3-12 parts of corrosion inhibitor, 20-65 parts of phosphoric acid and 25-75 parts of sulfuric acid by weight, wherein the total parts by weight is 100; the brightening agent comprises 1-4 butynediol and glycerin; and the corrosion inhibitor comprises phytic acid and polyphosphoric acid; II, heating the polishing solution to 85-120 DEG C; III, soaking a dry and clean aluminium product to be polished in the polishing solution in the step II for 20-240 seconds; IV, taking out the aluminium product in the step III and then washing the aluminium product with deionized water at 60 DEG C twice; and V, taking out and then blow-drying the aluminium product in the step IV.

Description

technical field [0001] The invention relates to the field of polishing methods for metal products, in particular to a polishing method for aluminum products. Background technique [0002] At present, the polishing method of aluminum products used at home and abroad mostly adopts the traditional "three acid" chemical polishing liquid. Due to the use of nitric acid, a large amount of yellow smoke is produced during polishing, which will cause air pollution and seriously endanger the health of workers; The "two-acid" chemical polishing solution without nitric acid used in the technology solves the technical problem of yellow smoke hazards, but the polishing effect is not good, and the surface gloss of aluminum products is not enough and not bright enough. Contents of the invention [0003] The technical problems to be solved by the invention are: eliminating the harm of yellow smoke caused by nitric acid; the technical problems that the surface polishing effect of aluminum pr...
