Surface treatment process of aluminum product workpiece

Abstract

The invention discloses a surface treatment process of an aluminum product workpiece. The surface treatment process is easy to implement, low in cost, low in noise and small in dust pollution. The surface treatment process includes the following steps that firstly, multiple stainless steel balls are poured into a grinding chamber of a vibration grinding machine to form a stainless steel ball heap, clean water is poured into the grinding chamber of the vibration grinding machine, the level of the poured clean water is higher than the stainless steel ball heap, and aluminum to be treated and an aluminum alloy workpiece to be treated are poured into the grinding chamber of the vibration grinding machine; secondly, an aluminum alloy cleaning agent is added to the grinding chamber of the vibration grinding machine to be ground, vibrated and cleaned, and the grinding, vibration and cleaning time ranges from 3 min to 5 min; thirdly, an aluminum alloy brightening agent is added to the grinding chamber of the vibration grinding machine to be subjected to grinding brightening treatment, and the grinding brightening time ranges from 8 min to 12 min; fourthly, the aluminum and the aluminum alloy workpiece treated in the third step are taken out and cleaned; fifthly, the aluminum and the aluminum alloy workpiece treated in the fourth step are put into a drying box to be dried, the drying temperature ranges from 130 DEG C to 150 DEG C, and the drying time ranges from 5 min to 8 min.

Description

[0001] This application is a divisional application of "a surface treatment process for aluminum and aluminum alloy workpieces". The application number of the original application is 2013106369513, and the application date is November 27, 2013. technical field [0002] The invention relates to a surface treatment process for aluminum workpieces. Background technique [0003] 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.

Problems solved by technology

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

[0004] At present, the surface treatment of aluminum and aluminum alloy workpieces mostly adopts anodic oxidation, electrostatic powder spraying or electroplating process. Among them, anodic oxidation treatment is not suitable for the surface of fire-fighting interface and its accessories made of die-casting aluminum. The surface of the fire-fighting interface and its accessories made of aluminum is protected, and the surface of the fire-fighting interface and its accessories will be oxidized and darkened, or even blackened; although electrostatic powder spraying or electroplating process can be used for fire-fighting made of die-cast aluminum The surface of the interface and accessories is treated, but the electrostatic powder spraying process has many pre-treatment processes, the deburring noise of sand blasting is large, the dust pollution is large, and the cost is high. At the same time, problems such as missing spray and unevenness will occur for workpieces with complex structures. ; The electroplating process has defects such as high cost and complicated process, and at the same time, the electroplating will not be in place for workpieces with complex structures
