Abstract
The invention provides an aluminum profile oxidization operating method which sequentially comprises the following steps: degreasing, rinsing, alkaline etching, rinsing, neutralizing, rinsing, oxidizing, sealing and drying. The aluminum profile oxidization operating method has the advantages and positive effects of being smooth in surface of the profile, and enabling the prepared compound film to have wear resistance, durability, corrosion resistance and brightness.
Description
Technical field
The invention belongs to the aluminium section bar manufacture field, especially relate to a kind of oxidation operation method of aluminium section bar, is the one procedure before aluminium section bar carries out electrophoresis.
Background technology
Oxidation is meant that in electrolyte solution the section bar that will have conductive surface places anode, under the effect of extrinsic current; Process making surface formation sull is called anodic oxidation; The film that is produced is an anode oxide film, thereby improves the anticorrosive of section bar, oxidation resistant ability.Section bar is nonconducting after the oxidation.According to the size of oxidation section bar and the demand of section oxidation, divide big oxidation and little oxidation.The last folder state of section bar is divided into horizontal type and vertical during according to the section bar oxidation.Big oxidation: section bar is bigger, is generally more than the 3m, no end face requirement; Little oxidation: general section bar is less, and end face also requires oxidation.The oxidation of aluminium section bar is a traditional technology, still, in oxidising process, the section bar surface irregularity can occur, and the composite package of generation has problems such as wear resistance, weather resistance, solidity to corrosion and light property be not up to standard.Therefore, need carry out perfect to technology.
Summary of the invention
The oxidation operation method that the purpose of this invention is to provide a kind of aluminium section bar is the one procedure before aluminium section bar carries out electrophoresis.
The present invention is that technical scheme is following:
A kind of oxidation operation method of aluminium section bar may further comprise the steps successively: degreasing, washing, alkali erosion, washing, neutralization, washing, oxidation, sealing, baking.
Further, when washing, section bar hangs water surface hypsokinesis gradient and stopped about 30-40 seconds, when dripping, does not get into subsequent processing until section bar.
Further, alkali when erosion, with the section bar groove down that tilts slowly, 1-10 minutes time, groove basicity be PH 10, after the time arrives, should sling immediately, and the time of dripping is unsuitable long, be attached on the section bar in order to avoid cause that alkali lye Yin Wendu is too high, bring difficulty to neutralization.
Further, the washing after the alkali erosion need be carried out 3 times.
The pH of the washing bath of further, washing after the neutralization＞3.
Further, baking is carried out under 160-180 ℃, and general storing time is 15-25 minute
Advantage and positively effect that the present invention has are: section bar surfacing, the composite package of generation have wear resistance, weather resistance, solidity to corrosion and light property excellent characteristics.
Embodiment
For example the present invention is further specified below.
Degreasing: purpose: remove the blank surface greasy dirt, normal temperature production.Hang material and go into groove, 2-8 minutes time, should tilt to stop about 30-40 seconds when hanging 10 centimeters high of groove faces, flow out to drop and the continuity phenomenon no longer occurs, can not just cross Rinsing Area by overstand.
Washing: behind the washing process regulation tank; Must treat the section bar two ends no longer just can sling behind the bubbling (can not in water washing process overstand) hang water surface hypsokinesis gradient and stopped about 30-40 seconds, flow out to drop and no longer include the continuity phenomenon and just go into subsequent processing.
Alkali erosion: purpose: remove section bar surface film oxide and residual greasy dirt, smooth section bar surface action, groove basicity is pH < 10.During operation, the groove down that tilts slowly, 1-10 minutes time.After the time arrives, should sling immediately, and the time of dripping is unsuitable long, be attached on the section bar in order to avoid cause that alkali lye Yin Wendu is too high, bring difficulty to neutralization.
Washing: carry out three washings after the alkali erosion, after hanging material and going into tank, section bar two ends liquid level must can be sling behind the no bubble, hangs liquid level rear-inclined stop about 30-40 seconds, the continuity phenomenon no longer occurs to the liquid drip.Washing must be clean, otherwise will cause the inhomogeneous part of sull that tangible stain is arranged, or sull spumescence vestige, and just drip-dry water allows neutralization.
Neutralization: purpose: remove after the alkali erosion and stick to the lip-deep AL of section bar (OH) 3, make the section bar surface reply the cleaning light.Operational requirement: normal temperature production, 1-5 minutes time, the fluid of slinging face tilt stopped about 30-40 seconds, and no longer occurring to drop continuously must the property phenomenon.Neutralization twice washing in back.
Washing: must behind washing, stirring, spray, could get into the oxidation trough oxidation after the neutralization; Before getting into oxidation channelization groove, every section bar must be behind stringing can oxidation; Simultaneously, whether the surface quality of inspection section bar reaches requirement before advancing groove; It is good to accomplish fully to guarantee conducting system.
After hanging material and going into tank, section bar two ends liquid level can not sling after having bubble, hangs the liquid level rear-inclined and stops about 30-40 seconds, flows out to drop continuous phenomenon no longer to occur.Washing bath acidity regulation: pH>3.
Oxidation: purpose: energising makes section bar surface epistasis lead last layer protective membrane, i.e. sull.
Operational requirement: technology is in the oxidation trough of being allowed for access under the steady state, tilts to get into oxidation trough and tilts to get into oxidation trough, avoids down the groove excessive velocities to produce the oxidation bubble.Should in time sling after oxidation has been switched on, leave the liquid level rear-inclined and stop and the continuity phenomenon no longer to occur to drip in about 30-40 seconds.About operation the time should lift by crane low that rising and cause the section bar balance, do not cause dropping liquid to ooze or drip on the other oxidation trough framed bent, and pollute section bar.After the oxidation, must after washing twice, could get into other operations such as painted groove or enclosed slot.Washing bath acidity regulation: pH>3.
Sealing: normal temperature sealing.Operational requirement: electrophoresis material is not carried out drug blockage, and common material medicine is 1um/ minute, about general 12 ± 3 minutes off-periods.Washing must be thorough, but also will avoid the sealing of hole overlong time and the mistake envelope, and sull destroys and a powder.Sealing finishes, and slings, and leaves liquid level and tilts to stop about 30-40 seconds, flows out to drop no longer to show the continuity phenomenon.Baking: purpose: make the composite package of generation have wear resistance, weather resistance, solidity to corrosion and light property.Operational requirement: under 170 ± 10 temperature, toast, general storing time is about 20 ± 5 minutes.Storing time must reach, otherwise influences composite package hardness, and storing time is long will to be toasted the enamelled coating jaundice and cause composite package to destroy.
Utilize the section bar surfacing of method oxidation of the present invention, the composite package of generation has wear resistance, weather resistance, solidity to corrosion and light property excellent characteristics.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
