Embodiment Construction

[0022] Taking the treatment of 1.5 tons of aluminum plate as an example, the surface treatment method of the aluminum plate includes the following steps: (1) Cleaning the surface of the aluminum plate: Use two non-woven brush rollers on the upper and lower sides to brush the two sides of the aluminum plate respectively. The purpose is to brush the surface of the aluminum plate and degrease it. That is to increase the specific surface area of ​​the aluminum plate and remove the grease on the surface of the aluminum plate; (2) roughening the surface of the aluminum plate: the aluminum plate undergoes a chemical reaction in a strong alkali solution to further roughen the surface of the aluminum plate and ensure the adhesion between the aluminum plate and the insulating medium layer The temperature of the lye is 50-80°C, and the soaking time is 2-4min. The lye includes the following raw materials in parts by weight: sodium hydroxide: 20kg; sodium phosphate: 12kg; sodium nitrate: 2kg...

Abstract

The invention provides a surface treatment method for an aluminum board. The surface treatment method comprises the following steps: (1) cleaning the aluminum board surface to remove impurities and grease on the aluminum board surface; (2) soaking the aluminum board in alkali liquor for 2-4 minutes, wherein the temperature of the alkali liquor is 50-80 DEG C; (3) soaking the aluminum board in a weak-acid solution for 3-5 minutes at 30-45 DEG C, wherein the weak-acid solution comprises the following raw materials in parts by weight: 50-60 parts of phosphoric acid, 20-30 parts of butanoic anhydride, 3-5 parts of ammonium hydrofen difluoride, 1-3 parts of boric acid and 2-3 parts of diammonium hydrogen phosphate; (4) performing water cleaning on the aluminum board; (5) drying the aluminum board. The surface treatment method disclosed by the invention has the beneficial effect that chemical oxidization is adopted, power is not used and the water is circulated, so that the energy consumption is greatly lowered; and the occurrence of safety accidents caused by strong acid and strong base is avoided.

Description

technical field [0001] The invention relates to a surface treatment method of an aluminum plate. Background technique [0002] The existing aluminum plate surface treatment process includes the following steps: [0003] (1) Coarsening: At this stage, the aluminum plate is put into a strong alkali (sodium hydroxide) solution for chemical reaction, the reaction temperature is controlled at 50-80°C, and the reaction time is 3-5min. The purpose is to degrease the surface of the aluminum plate and form a certain roughness, then take out the roughened aluminum plate, clean it manually and prepare for oxidation treatment; [0004] (2) Oxidation stage: In this stage, the aluminum plate is used as the anode, the lead or aluminum plate is used as the cathode, and the strong acid (sulfuric acid) solution is used as the electrolyte. The process of forming a 2-5um aluminum oxide insulating protective layer on the surface of the aluminum plate under the action of an electric field. The...
