Problems solved by technology

[0004] At present, the existing aluminum products generally need to be degreased in an alkaline solution. However, the aluminum products treated with an alkaline solution also need to be neutralized with an acidic liquid, which not only increases the production cost of aluminum products. The process steps also increase the process manufacturing cost, and the use is limited

Abstract

The invention discloses a surface treatment process for aluminum products. The surface treatment process comprises the following steps: 1, oil removing procedure, wherein an aluminum product is put into an alkaline solution to remove oil for 20-30 seconds, and then clean water is used for cleaning the aluminum product for one time; and 2, grinding procedure, wherein a plurality of silica particles are poured into the grinding chamber of an industrial vibration grinding machine, a silica particle pile is formed, clear water is poured into the grinding chamber of the industrial vibration grinding machine, the poured clear water submerges the silica particle pile, and the aluminum product after being treated in the oil removing procedure is poured into the grinding chamber of the industrial vibration grinding machine. According to the surface treatment process for the aluminum products, the aluminum product after being treated in the oil removing procedure is poured into the industrial vibration grinding machine with the plurality of silica particles to be subjected to grinding, on one hand, the silica particles can grind burrs on the surface of the aluminum product, on the other hand, silicon dioxides in the silica particles can neutralize the alkaline solution, and therefore, the aluminum product does not need to be added with an acidic solution for neutralization after being subjected to the oil removing procedure in the alkaline solution.

Description

technical field [0001] The invention relates to the technical field of surface treatment of aluminum products, in particular to a surface treatment process of aluminum products. Background technique [0002] Aluminum and aluminum alloys have a series of advantages such as low density, high strength, low cost, good corrosion resistance and formability, and are widely used in automobiles, construction, fire fighting equipment, bridges and other fields. However, the surface of aluminum and aluminum alloys is covered with an oxide film, which is easily corroded by strong acids and alkalis, and is prone to intergranular corrosion, with low surface hardness and no wear resistance; therefore, in order to overcome the above defects, aluminum And aluminum alloy workpiece surface treatment. [0003] With the development of aluminum smelting and processing technology, aluminum products are now widely used in aviation, building materials, vehicles, ships, light industry and other depar...
