Aluminum plate surface treatment technology

Abstract

The invention provides an aluminum plate surface treatment technology. The aluminum plate surface treatment technology solves the technical problems that in an existing treatment technology, strong acid and strong base need to be used, safety accidents are likely to happen, and the treating dangerousness is high. The aluminum plate surface treatment technology comprises the following steps that a, the surface of an aluminum plate is leveled; b, the aluminum plate is placed in water in which a degreased oil removal agent is added, the water temperature ranges from 40 DEG C to 60 DEG C, vibration cleaning is conducted, and the number of cleaning times ranges from 2 to 3; c, the aluminum plate is immersed in alkaline liquor, the temperature of the alkaline liquor ranges from 60 DEG C to 70 DEG C, and the immersing time ranges from 1 min to 3 min; d, the aluminum plate is washed; e, the aluminum plate is immersed in a weak acid solution at the temperature ranging from 40 DEG C to 55 DEG C for 2-4 min, wherein the weak acid solution comprises following raw materials including, by weight, 30-40 parts of diluted hydrochloric acid, 15-30 parts of butanoic anhydride, 4-8 parts of ammonium bifluoride, 2-4 parts of boric acid and 2-3 parts of diammonium hydrogen phosphate; f, the aluminum plate is subjected to spraying and washing, and the weak acid solution on the surface of the aluminum plate is removed; and g, the aluminum plate is dried through a drying system, the drying temperature ranges from 80 DEG C to 120 DEG C, and the drying time ranges from 8 min to 12 min. The aluminum plate surface treatment technology has the beneficial effect of being safe in treatment.

Description

technical field [0001] The invention relates to a treatment process for the surface of an aluminum plate. Background technique [0002] Aluminum has a series of advantages such as low density, high specific strength, good corrosion resistance and formability, and low cost. application. There are many methods to treat the surface of aluminum plate, and the widely used methods are physical method, chemical method, physical chemical method and comprehensive method. [0003] After searching, for example, Chinese patent literature discloses a surface treatment process for aluminum plates [application number: 201610331630.6; publication number: CN 105951150A]. This aluminum plate surface treatment process is characterized in that it includes the following steps: (1) Put the surface of the aluminum plate into a soaking tank and soak it in a soaking agent at 32°C for 2 minutes, rinse it with clean water, and then wipe it with a clean soft cloth. Gently wipe the surface of the alu...

Problems solved by technology

[0004] Although the treatment process disclosed in this patent can realize its surface treatment, it needs to use strong acid and strong alkali in this treatment process, which is prone to safety accidents and high risk of treatment. Therefore, it is very important to design a treatment process for the surface of aluminum plates. necessary
