Problems solved by technology

Using mechanical polishing, on the one hand, it will generate dust that will cause physical injury to the staff, and sometimes cause explosion accidents
On the other hand, due to the softness of the aluminum material, there will be traces of the polishing wheel, and it is not easy to produce a mirror effect
If electrochemical polishing is used, the polishing solution contains high concentration of sulfuric acid, which is highly corrosive, and chromic acid is carcinogenic to the human body, and the whole workshop is also full of sour smell, which has adverse effects on the human body
In addition, the electrochemical polishing takes a long time and the efficiency is low

Abstract

The invention discloses a liquid-phase plasma polishing liquid and a polishing process of an aluminum product. The polishing liquid comprises the following components calculated by weight percentage: 3-4 percent of ferric trichloride, 1-2 percent of ammonium chloride and the balance of purified water. The polishing process comprises the following steps of: mounting the aluminum product to be polished on a hanger and then soaking and showering in the purified water; pouring the liquid-phase plasma polishing liquid into a polishing groove; heating the liquid-phase plasma polishing liquid to be 70-90DEG C; soaking the aluminum product to be polished on the hanger into the liquid-phase plasma polishing liquid; connecting an anode of a liquid-phase plasma polishing machine with the aluminum product to be polished; connecting a cathode of the liquid-phase plasma polishing machine with a plurality of cathode plates in parallel; controlling an output polishing power supply to be 270-330V; taking the aluminum product out after polishing and soaking and showering; and drying the aluminum product. The liquid-phase plasma polishing liquid disclosed by the invention does no harm to an operator; and the polishing process disclosed by the invention has the advantages of short polishing time, high efficiency, greatly-improved glossiness of the aluminum product and the like.

Description

technical field [0001] The invention discloses a liquid plasma plasma polishing solution for aluminum materials, and also discloses a liquid plasma plasma polishing process for aluminum materials. Background technique [0002] Surface treatment of metals is becoming more and more widely used. Aluminum is a material that is widely used for its light weight and environmental friendliness, but polishing of aluminum is a relatively difficult technology. The use of mechanical polishing, on the one hand, will generate dust that will cause physical injury to the staff, and sometimes cause explosion accidents. On the other hand, because the aluminum material is relatively soft, it will leave traces of the polishing wheel, and it is not easy to produce a mirror effect. If electrochemical polishing is used, the polishing solution contains high concentration of sulfuric acid, which is highly corrosive, and chromic acid is carcinogenic to the human body, and the whole workshop is also...
