Description
Technical field
The invention belongs to cleaning agent fields, and in particular to a kind of metal greasy dirt cleaning agent and preparation method thereof.
Background technology
Metal cleaner is mainly used for the cleaning in parts production, and in the surface treatments such as application, plating, degreasing is weight
The technical process wanted, the degreasing degree on metallic article surface will directly influence the subsequent processing quality of workpiece.
In modern production life, metal is widely used in building, machinery, metallurgy, electronics, packaging, automobile and high-tech
Etc. each important department, they not only make functional material while also making structural material, penetrate into every field.
In the industrial production, metal parts is even without the processing of the postorders such as plating painting and other surface treatments, in production
Some stage will also remove degreasing.In oil and gas pipeline, fuel nozzle, oil refining apparatus etc. after the operation of some cycles,
Often accumulate a certain amount of residual oil dirt.It is easy to lead to equipment breakdown and safety accident, this just gives production and site operation
Safety hides some dangers for, and it is very necessary regularly to carry out device cleaning.
In the metal cleaning process of early stage, the organic solvent types chemical reagent such as gasoline, kerosene, diesel oil are mostly used as cleaning
Agent degreases.Such metal cleaner is to serious waste of resources, while safety in utilization is low.It is fallen in cleaning technique
Afterwards, shortage of resources and the transformation of Traditional Thinking difficulty etc. be under the influence of many factors, industrial enterprise to metal equipment and pipeline into
The method of row decontamination cleaning, still rest on mostly mechanical cleaning, high-pressure washing, organic solvent cleaning and chemical pickling etc. some
Traditional stage generally uses the organic solvents such as gasoline, diesel oil, kerosene and acetone, trichloro ethylene, carbon tetrachloride, or uses
Pickling.Although there is certain effect of deoiling, the metal cleaner being commonly used can usually add some phosphorous assistants
With APEO class surfactants, these substances have prodigious harm to environment, and existing cleaning agent generally only cleans work(
Can, without antirust function, need to do antirust treatment at once after the washing, time-consuming and laborious, cost is higher.Therefore, it is necessary to open
Send out the strong metal cleaner of the decontamination antirust function of some environmental protection.
Invention content
The technical problems to be solved by the invention：It phosphorous is helped for can usually add some in current metal greasy dirt cleaning agent
Agent and APEO class surfactants, these substances have prodigious harm, existing cleaning agent generally only to clean work(environment
Can, it without antirust function, needs to do antirust treatment at once after the washing, time-consuming and laborious, the higher problem of cost provides one
