Description
Technical field
The present invention relates to a kind of environmentally-friendly water-based metal cleaner, be used for mechanical workout manufacturing metal parts inter process and clean with antirust.
Background technology
In automobile product and the component manufacturing, use and maintenance process; Often need to clean attached to the various dirts on product and the component surface (like the scrap metal in the course of processing, cutting fluid, abrasive material and various grease, ionogen and hand perspirations such as dust and acid, alkali, salt, frictional wear product and corrosion product or the like); And reach certain surface clearness; To ensure carrying out smoothly of manufacturing procedure, eliminate the hidden danger that metal is embroidered erosion and frictional wear, prevent to embroider the continuation development of erosion and wearing and tearing; Guarantee product inherence and surface quality, increase the service life.
Metal cleaner has broad variety, and the water fluid metal cleaner is being represented modern technique and development trend.
The water fluid metal cleaner is made up of kinds of surface promoting agent, washing assistant, rust-preventive agent, skimmer, mould inhibitor and water etc.Such clean-out system does not have smell or smell less, can not burn, and is safe in utilization, operator endangered little; The use preparation is convenient, cost is low; Cleaning performance is good, has good rust-preventing characteristic, non-corrosibility.The aqueous cleaning agent that contains nitrite has fabulous rust-preventing characteristic, but nitrite has severe toxicity, and the indirect carcinogenesis effect is arranged when using jointly with trolamine.And its rust-preventing characteristic of aqueous cleaning agent that does not contain nitrite is undesirable often, and cost is high again, and the user is reluctant to accept.Therefore, develop a kind of non-toxic, environmental friendly aqueous liquid cleansing, and rust-proof effect can with contain the nitrite product and comb mutually that U.S.A, cost slightly increase or the moderate inevitable choice that just becomes.
Summary of the invention
The purpose of this invention is to provide a kind of environmentally-friendly water-based metal cleaner; It forms by tensio-active agent, washing assistant, rust-preventive agent, solubilizing agent, skimmer, mould inhibitor and water are composite, is homogeneous transparent, no layering, nothing deposition liquid, is applicable to that cast iron, steel part mechanical workout inter process clean and the preceding cleaning of rust-proof seal; Be applicable to that also non-ferrous metal mechanical workout inter processes such as aluminium, copper clean; Can clean simultaneously, have antirust, the corrosion-resisting function of inter process and short-term multiple metal material part, combined assembly, can be with electrodeposit, spray paint, process matchings such as baking vanish, mopping; But normal temperature cleans, the heated wash better effects if.
