Problems solved by technology

However, the dripping time is too short, and there is still a lot of bath liquid on the surface of the aluminum material. After the bath liquid is brought into the washing tank, the bath liquid in the two-acid main tank will gradually decrease, and the acidity of the water in the washing tank will continue to increase. Affecting the washing effect of aluminum in the washing tank
Therefore, in continuous production, it is necessary to continuously replenish the acid solution to the two acid main tanks, and the water washing tank needs to constantly replace the fresh water in the tank, thereby increasing the production cost of the tank solution and wasting more fresh water resources

Abstract

The invention discloses a polishing bath of an aluminium material. The polishing bath of the aluminium material comprises a two-acid main bath and a rinsing bath, and further comprises a two-acid sub bath, wherein the two-acid sub bath accommodates a bath solution, and is equipped with a cooling device used for dissipating heat of the bath solution. The invention further discloses an aluminium material polishing production technology utilizing the polishing bath of the aluminium material. During aluminium material polishing production, after polishing of the two-acid main bath, the two-acid sub bath is newly added for temperature decreasing treatment, the temperature of the bath solution is controlled between 10 DEG C and 40 DEG C through temperature decreasing of the cooling device, the high-temperature aluminium material is quickly cooled, and the bath solution is enabled to drip for a long time till the bath solution is empty, so that the bath solution in the two-acid main bath is recycled during aluminium material polishing, and the unnecessary waste of raw materials such as phosphoric acid and sulfuric acid, and the fresh water resource is avoided.

Description

Technical field [0001] The invention relates to the field of metal surface treatment, in particular to an aluminum polishing groove and a production process thereof. Background technique [0002] In the existing two-acid smokeless polishing technology for aluminum materials, the polishing tank includes a two-acid main tank and a water washing tank. The two-acid main tank contains a bath liquid with phosphoric acid and sulfuric acid as main components. When the aluminum material is polished, the workpiece to be polished is moved into the continuously heated two-acid main tank, and its surface undergoes a strong acid etching reaction with sulfuric acid, and a thin aluminum layer on the surface of the aluminum material is dissolved and removed to achieve the polishing effect. After the aluminum material is polished, a short tank drop flow is performed on the two acid main tank, and then moved into the water washing tank for subsequent treatment. [0003] The aluminum material undergo...
