Embodiment 1

[0032] A production process of Yiji electrophoresis, the preparation process mainly includes blank putting on the shelf, degreasing, first water washing, alkali etching, second water washing, stain removal and ash removal, third water washing, pure water washing, hot pure water washing, Pure water washing, electrophoresis in the main tank, the fourth water washing, the fifth water washing, drip drying, oven curing, and the finished product is removed from the shelf. The specific steps are as follows:

[0033] (1) Blank put on the shelf

[0034] Put the blank on the shelf, the blank is preferably an aluminum alloy profile blank.

[0035] (2) Degreasing

[0036] Carry out degreasing treatment on the blank, the degreasing agent is sulfuric acid 140-180g / L, the treatment time is 6-12min, the degreasing temperature is 25-35°C, and then the first water washing is carried out.

[0037] (3) Alkali corrosion

[0038] Put the billet after step 2) into the alkali etching tank, the con...

Embodiment 2

[0056] On the basis of Example 1, the present invention proposes a production process for easy pole electrophoresis. The preparation process mainly includes putting the blank on the shelf, degreasing, washing for the first time, alkali etching, washing for the second time, removing stains and dust, and washing for the second time. Three washings, pure water washing, hot pure water washing, pure water washing, main tank electrophoresis, fourth water washing, fifth water washing, drip drying, oven curing, finished product removal, the specific steps are as follows:

[0057] (1) Blank put on the shelf

[0058] Extrude the billet and put it on the shelf.

[0059] (2) Degreasing

[0060] Carry out degreasing treatment on the billet extrusion billet. The purpose of degreasing is to remove the oil stain on the surface of the billet and loosen the natural oxide film on the surface of the aluminum material. The degreasing agent is sulfuric acid 150g / L, and the treatment time is 10min....

Embodiment 3

[0074] On the basis of Example 1, the present invention proposes a production process for easy pole electrophoresis. The preparation process mainly includes putting the blank on the shelf, degreasing, washing for the first time, alkali etching, washing for the second time, removing stains and dust, and washing for the second time. Three washings, pure water washing, hot pure water washing, pure water washing, main tank electrophoresis, fourth water washing, fifth water washing, drip drying, oven curing, finished product removal, the specific steps are as follows:

[0075] (1) Blank put on the shelf

Abstract

The invention discloses an extremely-easy electrophoresis production process and aluminum sections produced by using same. The production process comprises the following steps: placing blank on a rack, carrying out oil removal treatment on the blank, washing for the first time, carrying out alkali etching, washing for the second time, removing stain and duct, washing for the third time, washing with pure water, washing with hot pure water, washing with pure water, carrying out electrophoresis in a main channel, washing for the fourth time, washing for the fifth time, dripping to dryness, baking for curing, and taking finished products away from the rack. Compared with the prior art, the extremely-easy electrophoresis production process provided by the invention can be applied to all aluminum alloy section manufacturers, and can omit two processes, i.e., anodizing and coloring which are high in energy consumption, thus being not only energy-saving and environmentally-friendly, but alsogreatly shortening the production time and being stable in quality; the produced aluminum sections are high in corrosion resistance of surface film layers, long in time of weather resistance, multiplein surface colors and high in selectivity of home decoration materials.

Description

technical field [0001] The invention relates to the technical field of surface treatment of aluminum profiles, in particular to a production process of Yiji electrophoresis and the produced aluminum profiles. Background technique [0002] With the vigorous development of the national economy, at present, my country is a big country of aluminum consumption. Electrophoretic coating is to immerse the coated metal product in the electrophoretic coating after degreasing, cleaning, surface adjustment, phosphating, pure water cleaning and other pre-treatments. Uniform water-insoluble coating film, after the coating film is dried, has strong corrosion resistance, thereby prolonging the service life of the product. The preparation process of ordinary aluminum alloy profiles coated with electrophoretic paint generally includes the steps of pretreatment-anodizing-coloring-electrophoresis-curing, and as people's awareness of environmental protection and energy saving continues to stren...
