Processing method of corrosion-resistant aluminum plate

Abstract

The invention discloses a processing method of a corrosion-resistant aluminum plate. The processing method comprises the following steps that (1) raw materials including 10 parts of magnesium, 10 parts of chromium, 5 parts of titanium and 70 parts of aluminum are put into a smelting furnace to be calcined at the temperature of 700 DEG C for 15 min and then cooled to 350 DEG C at the cooling speed of 10 DEG C / s, 9 parts of carbon is added into the smelting furnace, and 50 min later, a metal mixed solution is obtained; (2) after pouring the metal mixed solution for casting an aluminum plate blank , rolling is performed to prepare a primary aluminum plate; (3) the primary aluminum plate is subjected to an oil removal process, the primary aluminum plate is fished out 15 minutes later and subjected to ultrasonic cleaning, and the surface of the primary aluminum plate is polished; (4) the polished primary aluminum plate is washed clean with deionized water and dried at the temperature of 35 DEG C; and 5) finish paint is sprayed on the dried primary aluminum plate to obtain the aluminum plate. Chromium is a representative ferrite forming element and an element for improving corrosion resistance, alloy elements are dissolved with ferrite, alloy ferrite can be formed, and the strength, hardness and corrosion resistance of the aluminum plate can be improved.

Description

technical field [0001] The invention relates to the technical field of aluminum plate processing, in particular to a processing method for a corrosion-resistant aluminum plate. Background technique [0002] Aluminum plate refers to the aluminum material with a thickness of more than 0.2mm to less than 500mm, a width of more than 200mm, and a length of less than 16m. With the advancement of large equipment, there are more aluminum plates that can be as wide as 600mm). Aluminum plates refer to rectangular plates processed by rolling aluminum ingots, which are divided into pure aluminum plates, alloy aluminum plates, thin aluminum plates, and medium-thick aluminum plates. Patterned aluminum plate; [0003] With the improvement of people's living standards and the progress of society, daily necessities such as air conditioners, refrigerators, and automobiles have gradually entered thousands of households.

Problems solved by technology

[0003] With the improvement of people's living standards and the progress of society, daily necessities such as air conditioners, refrigerators, and automobiles have gradually entered thousands of households. Plates such as air conditioner condensing plates, refrigerator shells, and automobile chassis are often in humid environments. Therefore, for these There are certain requirements for the anti-rust performance of the board. The existing materials generally use plastic board or aluminum board. The disadvantage of the plastic board is that its strength and hardness are low. Due to environmental pollution, rainwater will have a corrosive effect. Long-term exposure to the sun and rain It will cause corrosion to the aluminum plate, but the existing aluminum plate has weak anti-corrosion effect
