Abstract

The invention discloses an aluminum substrate surface biological treatment oxidation process. The process comprises the following steps that, S1, an aluminum substrate is pretreated, oil removal treatment is carried out on the surface of the aluminum substrate, and washing is carried out; S2, oxidation treatment is carried out on the aluminum substrate, biological bacteria treatment oxidation is carried out on the pretreated aluminum substrate, an alumina dense film is generated, wherein oxidation treatment comprises the step of immersing the aluminum substrate in aqueous liquid containing acidophilic bacteria, the adding amount of the acidophilic bacteria is 50-500 g/L, the pH of the aqueous liquid is 2-6, and the immersion time is 5-10 h; S3, air is introduced into immersion liquid in the oxidation treatment process, and the introduction amount of the air is 1-5 L/h; and S4, the aluminum substrate is cleaned and dried. According to the process, the oxidized aluminum substrate is cleaned and dried through a cleaning and drying device, the process efficiency is improved, the production speed is increased, manual participation is not needed, the labor cost is greatly reduced, and the corrosion resistance of the aluminum substrate oxide film can be improved.

Description

technical field [0001] The invention relates to the technical field of aluminum substrate oxidation, in particular to a biological treatment oxidation process for the surface of an aluminum substrate. Background technique [0002] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided panel is composed of three layers, which are circuit layer, insulating layer and metal base layer. Commonly found in LED lighting products. There are two sides, the white side is for soldering the LED pins, and the other side shows the natural color of aluminum, which is usually coated with heat-conducting gel and then in contact with the heat-conducting part. At present, there are ceramic substrates and so on; in the production process of aluminum substrates, it is necessary to oxidize the aluminum surface to form an aluminum oxide layer. Aluminum alloy surface treatment usually adopts anodic oxidation, chemical conversion trea...
