Description
Technical field
The present invention relates to a kind of sanitising agent, relate in particular to the agent and preparation method thereof that descales of a kind of high-efficiency environment friendly degreasing and rust removal.
Background technology
In known technology, degreasing and rust removal for metallic substance and metal products surface, traditional method has two kinds substantially at present, a kind of is to utilize manually carry out the cleaning of greasy dirt and scrape or the mode of metal brush wiper eliminates rust with cutter, not only labour intensity is large, and the manpower needing is many, and efficiency is low, and the rust dirt that causes of rust cleaning flies upward everywhere, to environment around.This kind of mode is only suitable for the pre-treatment of greasy dirt and the not too serious metallic surface of rust staining, and is stained with a large amount of greasy dirts and rust staining for metallic surface, is just difficult to remove clean.Another kind method is to utilize highly basic oil removing, and the twice matting of strong acid rust cleaning completes, and the method one is to build Liang Ge operating pool, and the place taking is large; The 2nd, cleaning bothers, speed is slow, efficiency is low; The 3rd, when cleaning, must be careful, because the use of highly basic and strong acid is all harmful, there is unsafe hidden danger.Especially use high-intensity hydrochloric acid to there is the tart flavour of harmful toxins, human body is had to strong impulse sense, and the acid mist severe contamination air producing; The 4th, the discharge severe contamination water resources of waste acid water, affects and has destroyed the Sustainable development of water resources.The 5th, the general stop after 3 minutes in atmosphere of the metallic surface after concentrated hydrochloric acid cleans can produce secondary oxidation corrosion, therefore, can only play temporary corrosion inhibition.
At present, have a variety of electrochemical deoiling rust removers to metallic substance both at home and abroad, they are all that directly to use the biology of mineral acid or ammonia be major ingredient, are equipped with that the interpolation dressing such as tensio-active agent, inhibiter make.As: patent announcement number is the disclosed a kind of oil-removing rust-removing agent of CN86407238A, what it was raw materials used consists of: aluminium powder, sodium hydroxide, hexamethylenetetramine, polyoxyethylene aliphatic alcohol ether, oxyethane, water, phosphoric acid, and be mixed with according to certain ratio, although this oil-removing rust-removing agent efficiency is higher, but because the oxyethane character in raw material is unstable, toxic again, dangerous in production process, more serious to the pollution of environment.And production cost is very high.Notification number is the disclosed a kind of rust-removing passivator of CN1004429A, to be mixed according to a certain percentage by phosphoric acid, primary zinc phosphate, oxalic acid, zinc nitrate, polyoxyethylene glycol octyl group alkyl oxide, water, but because ether material character is unstable, so the shelf time of product is short, easily lost efficacy.Its rust cleaning effect is not very good simultaneously.< < Science and Technology Daily > > has reported " MX-1 " water-base metal rust-removing and-preventing agent of Beijing a company development on August 7th, 2000, this rust remover need to heat use under the condition of 80 ℃, also need under special circumstances with after brush brush, coat again new slushing oil on metallic surface after, just can reach rust cleaning effect, very trouble.
