Embodiment 1

[0027] Aluminum surface treatment process, the process is as follows:

[0028] (1) Pre-soaking: the three-layer aluminum alloy plate is dried by blower after soaking in sodium hydroxide solution respectively;

[0029] (2) Surface treatment: use a steel brush to polish the lower surface of the upper aluminum alloy sheet 1, the upper and lower surfaces of the middle aluminum alloy sheet 2, and the upper surface of the lower aluminum alloy sheet 3;

[0030] (3) Surface cleaning: Use a brush to clean the polished three-layer aluminum alloy plate, and suck the surface dirt through the suction pipe;

[0031] (4) Apply lubricant: stack the three-layer aluminum alloy plates after surface cleaning into one, and coat a layer of lubricant on the upper surface of the upper aluminum alloy plate and the lower surface of the lower aluminum alloy plate.

[0032] The treatment process of the present invention is realized by a surface treatment device, and the surface treatment device includes...

Abstract

The invention relates to a processing technology for surfaces of an aluminum plate. The technology comprises the following steps of (1), pre-soaking, specially, three layers of aluminum alloy plates are correspondingly soaked by a sodium hydroxide solution and then and blow-dried by an air blower; (2), processing surfaces, specially, the lower surface of the upper layer aluminum alloy plate, the upper and lower surfaces of the middle layer aluminum alloy plate and the upper surface of the lower layer aluminum alloy plate are polished through a steel brush; (3), cleaning the surfaces, specially, the polished three layers of aluminum alloy plates are cleaned through a hairbrush, and smudginess on the surfaces are sucked clearly through a suction pipe; (4), coating a lubricant, specially, the three layers of surface-cleaned aluminum alloy plates after the surfaces of the surface-cleaned aluminum alloy plates are cleaned are stacked into a whole, and a layer of lubricant is coated on the upper surface of the upper layer aluminum alloy plate and the lower surface of the lower layer aluminum alloy plate. By means of the processing technology for the surfaces of the aluminum plate, oil contamination on the surfaces of the plates can be removed effectively, combining surface is increased, and interface combining strength of the composite plate is improved.

Description

technical field [0001] The invention relates to a surface treatment process, in particular to an aluminum plate surface treatment process. Background technique [0002] Brazed heat exchangers include: radiators, water tanks, condensers, evaporators, oil coolers, intercoolers, PTC heaters, etc., and their applications involve automobiles, home / commercial air conditioners, high-speed rail, power station air cooling, ships, aerospace Aviation, transportation, construction engineering, electronic appliances and electric energy, etc. Because aluminum alloy has low density, high specific strength, good electrical and thermal conductivity, excellent plasticity, can be processed into materials of various complex shapes, can be surface treated into various colors, has good corrosion resistance, long service life, and can be recycled. Therefore, it has gradually become a main heat conduction material, especially in the aspect of functional radiators, aluminum materials have become th...
