Abstract
The invention relates to the technical field of aluminum material processing and specifically relates to an anodizing technique for an aluminum evaporator. The anodizing technique comprises the processes of removing oil; washing with water 1; washing with water 2; neutralizing; washing with water 3; washing with water 4; anodizing; washing with water 5; washing with water 6; blanking. The anodizing technique for the aluminum evaporator provided by the invention has the advantages of simple production process, convenience in control, high production efficiency, low cost, and the like.
Description
Technical field
The present invention relates to aluminum profile extrusion technical field, particularly belong to a kind of aluminum evaporator anode oxidation process.
Background technology
Aluminum evaporator such as evaporator fin, plate pipe evaporator etc. is widely used in refrigerator refrigeration system, in order to overcome
The defect of the aspects such as aluminum evaporator case hardness, mar proof, corrosion, expands range of application, increases the service life, anodic oxygen
Change technology becomes an indispensable ring during aluminium alloy uses.
Content of the invention
It is an object of the invention to provide it is being easy to enterprise implement and a kind of aluminum of aluminum evaporator batch oxidation is steamed
Send out device anode oxidation process.
The technical solution used in the present invention is as follows:
A kind of aluminum evaporator anode oxidation process, washes 4 sun including in oil removing washing 1 washing 2 with washing 3
Pole oxidation washing 5 washing 6 lower part, described anodic oxidation:
(1) configure tank liquor: add pure water and sulphuric acid in oxidation trough, sulfate ion concentration reaches 150～250g/l, temperature:
18～22 DEG C；
(2) adjust oxidation current: oxidation voltage is adjusted to 16～20v, then opens time switch timing；
(3) enter groove and go out groove: aluminum evaporator is placed on suspender and enters groove, after 15～25min, aluminum evaporator goes out groove.
Described oil removing uses and imports in water by aluminium alkaline defatting agent, and after stirring, total alkali point reaches 15～
30 points.
Described neutralization uses and adds water to the 3/4 of cell body volume in neutralization chamber, is subsequently adding concentrated sulphuric acid, is stirred for
Rod stirs, and tank liquor total acid point reaches 25～50, and neutral temperature is room temperature, and the neutralization time is 2～3min.
Compared with the prior art, beneficial effects of the present invention are as follows:
A kind of present invention aluminum evaporator anode oxidation process, simple production process, be easy to control, production efficiency is high, low cost.
