Abstract
The invention relates to a cleaning agent special for a rare-earth grinding fluid. The cleaning agent is mainly prepared from, by weight, a complexing agent 1%-5%, a surfactant 10%-30%, a buffering agent 0.1%-2 % and the balance water. The cleaning agent special for the rare-earth grinding fluid produced by adopting the technical scheme is simple in production process, has high dispersity and adsorbability and is remarkable in cleaning effect, and no obvious grinding fluid residue exists on the surface of a workpiece after cleaning is completed. In addition, the oil cleaning rate is improved by compounding the surfactant, the treatment speed is high, and the roughness of the workpiece is not obviously affected. The buffering agent can make PH of the cleaning agent in a weakly alkaline state while effect initiating, formation of cleaning agent micelles is promoted, the critical micelle concentration is lowered, and the service life of the cleaning agent is prolonged.
Description
Technical field
The present invention relates to field of surface treatment, specifically rare earth lapping liquid scavenger specially.
Background technology
The mankind are very close with the relation of chemical industry, in the modern life, the most all be unable to do without chemical products, from material lifes such as clothing, food, shelter, row to the cultural life such as culture and arts, amusement, are required for chemical products and service for it.Some chemical products, in human development history, plays epoch-making important function.Their production and application, even represent certain historical stage of human civilization.
Ultra-precision Turning is the production technology that modern sophisticated industry is important, and it does not require nothing more than high accuracy, high-quality, and requires low cost and high repeatability.And ultraprecision grinding polishing is owing to having the process principle of uniqueness and to features such as process equipment, environmental factor are less demanding, the nanoscale even processing of atom level can be realized, become a pith in Ultraprecision Machining, it is achieved the critical material of ultraprecision grinding polishing is precise finiss goods.At present, the removal unit removing material with abrasive particle has reached the even sub-nanometer scale of nanometer, reach the highest surface smoothness, the lapping liquid containing abrasive material can be used, or use the polished film that abrasive material is fixed on film, point corase grind, middle mill, refine, several steps such as polishing are carried out, it is also possible to lapping liquid and polished film are combined cross-reference.
Polishing refers to utilize machinery, chemistry or the effect of electrochemistry, makes workpiece surface roughness reduce, to obtain light, the processing method of flat surface.It is the modification processing utilizing flexible polishing instrument and abrasive grain or other polishing mediums that surface of the work is carried out.Loading steel ball and fur fragment when essence is thrown in wooden barrel, rotation a few hours can get the surface of dazzling light continuously.Finished surface is immersed in polishing fluid and carries out by the polishing of precision scale, and polishing fluid is mixed by the chromium oxide micro mist that granularity is W5～W0.5 and emulsion.In addition with methods such as electrobrightenings.Tradition polishing powder complex manufacturing, easily impacts environment, and the production cycle is long.
There is presently no a kind of production technology simple, environment will not be impacted can mass production be specifically designed to the rare earth lapping liquid scavenger specially that rare earth lapping liquid cleans.
Summary of the invention
The present invention is just for above technical problem, it is provided that a kind of production technology is simple, environment will not be impacted can mass production be specifically designed to the rare earth lapping liquid scavenger specially that rare earth lapping liquid cleans.
The present invention is achieved through the following technical solutions.
Rare earth lapping liquid scavenger specially, is mainly made up of complexing agent, surfactant, buffer, and each Ingredients Weight percentage composition is: complexing agent 1%～5%；Surfactant 10%～30%；Buffer 0.1%～2%, surplus is water.Complexing agent is NTA or EDTA.Surfactant is the mixture of the two or more in APES, high-carbon fatty alcohol polyoxyethylene ether, polyoxyethylene carboxylate, fatty acid methyl ester ethyl oxide, sorbitan ester.Buffer is that sodium carbonate forms by weight the proportions of 1:1 with sodium acid carbonate.
The rare earth lapping liquid Special cleaning agent producing process using technical scheme of the present invention to produce is simple, there is higher dispersiveness and adsorptivity, cleaning performance is notable, after cleaning, surface of the work remains without obvious lapping liquid, simultaneously, the present invention improves the cleaning rate to grease by the compounding of surfactant, and processing speed is fast and will not significantly affect workpiece roughness.Buffer can make cleaning agent keep PH in alkalescent state onset when, promotes the formation of cleaning agent micella, reduces critical micelle concentration, extends cleaning fluid service life.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1:
First sorbitan ester 60g, fatty acid methyl ester ethyl oxide 60g being added in 500g water, be sufficiently stirred for and be heated to 80 DEG C, add EDTA15g, be sufficiently stirred for, add sodium carbonate and each 5g of sodium acid carbonate, be sufficiently stirred for, the polishing that then adds water is to 1L.
Embodiment 2:
First APES 30g, polyoxyethylene carboxylate 30g being added in 500g water, be sufficiently stirred for and be heated to 80 DEG C, add EDTA15g, be sufficiently stirred for, add sodium carbonate and each 5g of sodium acid carbonate, be sufficiently stirred for, the polishing that then adds water is to 1L.
The rare earth lapping liquid Special cleaning agent producing process using technical scheme of the present invention to produce is simple, there is higher dispersiveness and adsorptivity, cleaning performance is notable, after cleaning, surface of the work remains without obvious lapping liquid, simultaneously, the present invention improves the cleaning rate to grease by the compounding of surfactant, and processing speed is fast and will not significantly affect workpiece roughness.Buffer can make cleaning agent keep PH in alkalescent state onset when, promotes the formation of cleaning agent micella, reduces critical micelle concentration, extends cleaning fluid service life.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes made according to spirit of the invention or modification, all should contain within protection scope of the present invention.
