Abstract
The invention discloses a kind of process of surface treatment of aluminium alloy extrusions, belong to aluminium alloy section surface processing technology field.Specifically include following steps：(1) clean：Aluminium alloy extrusions is put into the mixed solution of the 30g/l of natrium carbonicum calcinatum 13, the 16g/l of anhydrous sodium phosphate 10, the 25g/l of AEO 15, the 8g/l of triethanolamine 4, the 4g/l of nonionic surfactant 2 compositions and cleaned after trichloroethylene steam oil removing is embathed；(2) ultrasonication：Degreasing agent is put into ultrasonic equipment, to the aluminium alloy extrusions pre- degreasing of progress and main degreasing, the operating time of pre- degreasing and main degreasing is 6 8min；(3) anodic oxidation：Aluminium alloy extrusions after degreasing is put into acid storage and carries out anodic oxidation, ph values are 8 9.5.The present invention can eliminate aluminium alloy extrusions in process of production caused surface scratch, scratch, peeling the defects of, can reduce the requirement to mould, and after anodic oxidation film layer outward appearance than more uniform, smooth, fine and close, so as to reach bright and clean smooth effect.
Description
Technical field
The present invention relates to a kind of process of surface treatment of aluminium alloy extrusions, belong to technical field of metal surface processing.
Background technology
The features such as aluminium alloy extrusions has light weight, than powerful, in beautiful color, and machinability is strong, therefore use range is got over
Come more extensive, China also suddenly becomes in the world maximum aluminium section bar production base and consumption market.Aluminium section bar is mainly used in making
Make military aircraft.After the war, because war industry is die-offed to the demand of aluminium section bar, aluminum i ndustry circle just starts to develop civilian aluminium profiles
Material, its application is set to expand to construction industry, container package industry, transportation, electric power and electronics industry, machine by aircraft industry
The each department of national economy such as tool manufacturing industry and petrochemical industry, is applied among daily life.Aluminium alloy extrusions is by aluminium
Alloy pig is at high temperature by mould extrusion forming, because die working length is often by contained high temperature impurity damage in alloy pig,
Therefore Surface of profile moulding mark is caused, poor surface smoothness, drastically influence Surface Quality of Aluminum Alloy Profiles, it is impossible to it is attached to improve product
It is value added.
The content of the invention
The present invention is to solve the above problems, the invention provides a kind of process of surface treatment of aluminium alloy extrusions.
The present invention realize technical scheme that its purpose uses for：Specifically include following steps：
(1) clean：Aluminium alloy extrusions is put into natrium carbonicum calcinatum 13-30g/l, nothing after trichloroethylene steam oil removing is embathed
Water sodium phosphate 10-16g/l, AEO 15-25g/l, triethanolamine 4-8g/l, nonionic surfactant 2-
Cleaned in the mixed solution of 4g/l compositions；
(2) ultrasonication：Degreasing agent is put into ultrasonic equipment, pre- degreasing is carried out to aluminium alloy extrusions and master is de-
The operating time of fat, pre- degreasing and main degreasing is 6-8min；
(3) anodic oxidation：Aluminium alloy extrusions after degreasing is put into acid storage and carries out anodic oxidation, ph values are 8-9.5.
The beneficial effects of the invention are as follows：The present invention can eliminate aluminium alloy extrusions in process of production caused surface scratch,
The defects of scratch, peeling, the requirement to mould can be reduced, and after anodic oxidation film layer outward appearance than it is more uniform, smooth, cause
It is close, so as to reach bright and clean smooth effect.
