Abstract
The present invention discloses Ultrasonic wave bright clean-out system before the anodic oxidation of a kind of high ferro vehicle special die casting aluminium workpiece, be made up of the component of following mass percent: potassium pyrophosphate 1 ~ 3%, borax 1 ~ 3%, tripoly phosphate sodium STPP 0.5 ~ 2.5%, metasilicate pentahydrate sodium 0.5 ~ 2.5%, trolamine 1 ~ 5%, promoting agent (QYL-20) 0.1 ~ 1.0%, AEO-9? 1 ~ 2%, alizarin assistant 1 ~ 2%, pull open powder 0.1 ~ 1.0%, JFC? 0.1 ~ 1.0%, defoamer 0.1 ~ 0.6% and deionized water surplus.Deionized water first joins in stainless steel cauldron by preparation method, starts agitator, and rotating speed is 60 revs/min, is slowly joined in reactor by solid part raw material, often adds a kind of raw material and all stirs at least 15 minutes; Slowly joined successively in reactor by liquid part raw material, often add a kind of raw material and all stir at least 10 minutes, being continuously stirring to solution is light brown clear liquid.
Description
Technical field
The present invention relates to a kind of aluminium matter workpiece ultrasonic cleaning agent, especially a kind of dirt can thoroughly removed on workpiece, ensure cleanliness factor and the luminance brightness of workpiece surface, Ultrasonic wave bright clean-out system and preparation method before the anodic oxidation of long-lived high ferro vehicle special die casting aluminium workpiece.
Background technology
Metal cleans, adopt corresponding processing unit and processing condition exactly, with specific solution, the dirt removal on metal products workpiece surface is fallen, product is made to reach the technical requirements of design, as ultrasonic cleaning, steam purge, high pressure cleaning, ozone-ultraviolet cleaning, ion beam cleaning and plasma clean etc., just need to carry out ultrasonic cleaning to it before die casting aluminium workpiece as special in high ferro vehicle anodic oxidation.There are two technical problems in existing high ferro vehicle special die casting aluminium workpiece anodic oxidation fore shell ultrasonic cleaning agent: one is that after cleaning, workpiece surface luminance brightness is not up to standard always; Two is that the cleaning liquid life-span is short, and every day is changed once, and cleaning cost is high.
Summary of the invention
The present invention is the above-mentioned technical problem in order to solve existing for prior art, a kind of dirt can thoroughly removed on workpiece is provided, ensures the cleanliness factor of workpiece surface and luminance brightness and Ultrasonic wave bright clean-out system and preparation method before the anodic oxidation of long-lived high ferro vehicle special die casting aluminium workpiece.
Technical solution of the present invention is: Ultrasonic wave bright clean-out system before the anodic oxidation of a kind of high ferro vehicle special die casting aluminium workpiece, is made up of the component of following mass percent: potassium pyrophosphate 1 ~ 3%, borax 1 ~ 3%, tripoly phosphate sodium STPP 0.5 ~ 2.5%, metasilicate pentahydrate sodium 0.5 ~ 2.5%, trolamine 1 ~ 5%, promoting agent (QYL-20) 0.1 ~ 1.0%, AEO-91 ~ 2%, alizarin assistant 1 ~ 2%, pull open powder 0.1 ~ 1.0%, JFC0.1 ~ 1.0%, defoamer 0.1 ~ 0.6% and deionized water surplus.
The preparation method of Ultrasonic wave bright clean-out system before a kind of above-mentioned high ferro vehicle special die casting aluminium workpiece anodic oxidation, it is characterized in that carrying out as follows: first join in stainless steel cauldron by calculating the deionized water weighed, start agitator, rotating speed is 60 revs/min, by calculate weigh solid part raw material potassium pyrophosphate, borax, tripoly phosphate sodium STPP, trisodium phosphate, metasilicate pentahydrate sodium, pull open powder and slowly join successively in reactor, often add a kind of raw material and all stir at least 15 minutes; Liquid part raw material trolamine calculating weighed again, promoting agent (QYL-20), AEO-9, alizarin assistant, JFC, defoamer join in reactor successively slowly, often add a kind of raw material and all stir at least 10 minutes, being continuously stirring to solution is light brown clear liquid.
The present invention is the acidic cleaner being applicable to ultrasonic cleaning, effectively can remove the dirt of the special die casting aluminium workpiece surface of high ferro vehicle, ensure that cleanliness factor and the luminance brightness of workpiece surface, reaches the specification of quality before anodic oxidation.And the usage period long (three days), reduce the production cost of the special die casting aluminium workpiece of high ferro vehicle, and No oxidation discoloration phenomenon in six months after cleaning.
