Description
Technical field
The present invention relates to the technical field of surface of aluminum and aluminium alloy, relate generally to a kind of whiten liquid and surface protectant without the aluminum of harmful components and the light of aluminium alloy.
Background technology
Aluminum and aluminium alloy are widely used in the industry, especially at automobile, and machine-building, the industry such as chemical engineering industry is widely applied.Wherein, keep aluminum and the original metallic luster of aluminium alloy the brightest.Favored by a large amount of clients and consumer.Up to the present on market light about aluminum and aluminium alloy to whiten liquid few, and major part uses strong acid or highly basic or uses containing ammonia nitrogen, fluorion.There is the problems such as contaminated air, murder by poisoning operator, waste water difficult treatment.Industrial application aluminum and aluminium alloy, at air, soil, the medium such as sea water uses, corrosion in various degree can be produced.Modern industry is done great damage by corrosion, the most only direct economic loss, and causes shut-down, the indirect loss of stopping production.Therefore effective safeguard procedures must be taked.Preventing metal erosion from can set about in terms of two, one is to control environment；Two is to control metal itself.Therefore corrosion control technology should include following number of ways: changes corrosive environment；Development of new resistant material；Anodic oxidation is protected；Metal is implemented the protection of various coatings.In various protection approaches, most widely used general with coating protection.Up to the present, the most not only keep aluminum and the original metallic luster of aluminium alloy but also protect aluminum and aluminum alloy surface to exempt from the protective agent of corrosion. present invention achieves aluminum and aluminium alloy whiten after its surface is protected, make aluminum and aluminium alloy keep white bright state for a long time.Aluminum and aluminium alloy after surface protectant processes can be used safely under conditions of outside is severe.Along with expanding economy, the consumption of energy resource, the deterioration of the ecological environment has become the biggest obstacle of economic development, environmental protection, and energy-conservation, reduction of discharging has become requisite link.Therefore, along with the raising of environmental requirement, the free of contamination substitute products of development of new in the urgent need to, succeeding in developing of this reaction, will be greatly improved plant efficiency and economic benefit for enterprise.The environmental protection of epoch imparting enterprise can be met simultaneously, energy-conservation, the responsibility of reduction of discharging.
Summary of the invention
In view of the above circumstances, it is an object of the invention to replace the formula of existing pollution with a kind of environmental protection liquid thus change operating environment, it is achieved be tasteless, nontoxic, harmless.And without waste liquid non-exhaust emission, therefore environmentally safe.
What the present invention mainly used whitens liquid is environmental protection, can be with low cost, expeditiously cleaning aluminum and aluminium alloy.Method involved in the present invention, aluminum and aluminium alloy environment-protection brightening whiten and its feature of protective agent is as follows:
Aluminum and aluminium alloy being soaked under conditions of 0 DEG C-80 DEG C whitens in liquid, soaks 0.5-15 minute, takes out workpiece washing, then soak at room temperature 3 minutes, washing in protection liquid, dries, get product.
According to technique described in claim, it is characterised in that whiten and liquid adds the mass fraction of solute be respectively host 7%, additive 1%-2%, brightening agent 2%-4%, add lustre to guarantor's photo etching 6%, complies with agent 2%-2.5%, energy producing agent 3%-5%, regulator 1.5%-3%, remaining is water.
According to the technique described in claim, it is characterised in that the temperature whitening liquid is 0 DEG C-80 DEG C, and liquid soak time is 0.5-15 minute.
The addition of energy producing agent, makes solution produce reaction with aluminium, increases and keep the speed that whitens of temperature of liquid, quickening aluminum and aluminium alloy, energy-conservation.
The addition of regulator adjusts the persistency whitening reaction effectively, increases the service life of liquid, energy-conservation.
The interpolation complying with agent makes liquid dramatically speed up along with the raising of temperature with the reaction of aluminum and aluminium alloy, shortens the time whitened, so that product is suitable for the speed of production line, it is achieved volume production.
Replacement pickle, with after a period of time, precipitates in liquid and gradually increases, and effect is deteriorated, and now can add stock solution by filtering, make liquid be continuing with, and without waste liquid and the discharge of waste gas in operating process, thus environmental protection.
In view of the above circumstances, it is an object of the invention to after aluminum and aluminium alloy light whiten, its surface to be protected, make aluminum and the permanent holding of aluminium alloy the brightest.Aluminum and aluminium alloy after surface protectant processes can be used safely under conditions of outside is severe.Because of three-waste free discharge, therefore environmentally safe.
The surface protectant that the present invention mainly uses can be with low cost, expeditiously solution aluminum and aluminum alloy surface anti-macula lutea phenomenon, it is achieved aluminum and aluminium alloy keep original metallic luster for a long time.Method involved in the present invention, aluminum and aluminum alloy surface protective agent, its feature is as follows:
Aluminum and aluminium alloy are after whitening liquid and processing, then soak at room temperature 3 minutes in surface protectant, washing, dry, get product.
According to technique described in claim, it is characterised in that the mass fraction antirust agent 10% of each solute, organic additive 1%-2% in surface protectant; inorganic additive 2%-3%, film former 1%-2.5%, homogenizing agent 3%-5% sustained release drug 0.5%-1%; blender 1%-3%, remaining is water.
According to the technique described in claim, it is characterised in that surface protectant uses at normal temperatures, soak time is 3 minutes.
The addition of film former, makes solution produce reaction with aluminium, makes the surface of aluminum and aluminium alloy form protective layer.
The addition of blender adjusts aluminum and alloy surface film reaction effectively, increases the service life of liquid, energy-conservation.
The interpolation of sustained release drug makes liquid permanently effective with the reaction of aluminum and aluminium alloy, makes liquid permanency matter, energy-conservation.
The addition of homogenizing agent, the protecting film uniformity making aluminum and aluminum alloy surface be formed is good.
After aluminum and aluminum alloy surface protective agent use a period of time, such as poor effect, stock solution can be added, make liquid be continuing with.As there is adding the best situation of stock solution effect, now liquid is due in neutral and do not contain any material forbidding discharge, therefore can directly discharge, and has saved the air pollution of great number and expense that waste water processes, environmental protection.
