The cleaner does not contain phosphates, does not cause the problems such as water contamination or eutrophication, and has energy saving and environment protecting effects while having great cleaning effect to ferrous and non-ferrous metals. Compared with the prior art, the alkaline cleaner not only can wash off impurities such as metallic oxide, but also can wash away oil sediments on the surface of metal workpieces through synergistic effects of multiple components, thus achieving good cleaning effects, and effectively improving permeability of surface films, facilitating subsequent machining procedures. The invention also discloses a preparation method and a using method of the environment-friendly alkaline cleaner.
Description
Technical field
The present invention relates to a kind of green alkaline scavenging solution and preparation method, belong to smelting and processing of metals technical field.
Background technology
Since 20th century, along with the development of modern industry and the breakthrough of constantly bringing forth new ideas of science and technology, as cleaning the requisite clean-out system of link in industrial production, the kind scale of its research and development and corresponding range of application are also in continuous expansion.Meanwhile people are also changing gradually for the understanding of clean-out system and its utilization in daily life.Before eighties of last century fifties, the view that people clean for industrial equipments also rests on: carrying out cleaning to industrial equipments, to produce certain harm to equipment be the emergency schedule of doing something against one's will.But only pass by more than 10 year, namely after the sixties in 20th century, the idea of people just thoroughly changes into: utilizing matting to carry out cleaning to industrial equipments is that one can effectively maintain industrial equipments and normally produces running, improve the quality of production of product, the safe operation of guarantee equipment, in the work-ing life of extension device, reduce the important means to starting material and the consumption of the energy and the pollutent of removing production process generation.Along with the development of world economy and scientific and technical making rapid progress in more than 10 year of having pass by, clean industry worldwide all obtains significant progress.Special in the developed country of some America and Europes, the effective utilization for cleaning product and technology thereof has become the important means that these developed countries improve constantly the quality of the life of the people.This also for cleaning technique development and cleaning agent formula continue to optimize the condition providing necessity, the cleaning industry of taking this as an opportunity concerned countries is also constantly opened up the larger market space.Generally speaking, cleanly till now to have developed in order to the important integral part closely bound up with people's material and cultural life.
Metal processing and storage process in, especially in machining process, easily by oil pollution.Some workpiece gets rusty in storage process for preventing, and needs to smear slushing oil or rust preventing grease is protected.The existence of greasy dirt affects the wetting and bonding force of coating on metallic matrix, therefore metallic substance is needed to need to clean before processing, and the consumption of the precision components used in the ordinary mechanical part adopting metal material processing to prepare and other field is quite large, the workload of therefore cleaning this kind of metal parts is also corresponding very large, and the usage quantity of the clean-out system needed in cleaning process is also sizable certainly.Along with the severization of environmental protection requirement standard, also more and more stricter to the emission control of trade effluent, the discharge of therefore a large amount of sub-standard clean-out systems becomes the important topic needing research.In addition, existing metallic copper material detergent mostly is solvent-borne type, phosphorous aqueous cleaning agent etc., the shortcoming that these clean-out systems exist is, cleaning performance is not bery desirable, easily there is the top layer of black in the metallic element after cleaning, makes troubles to following process, causes puzzlement especially to the processing of precision components; Comparatively strong to equipment corrosion, increase equipment cost; Scavenging period is longer.
Alkali lye degreasing is the greasy dirt utilizing the saponification of alkali, the emulsifying effect of tensio-active agent etc. to remove workpiece surface.Alkaline cleaner be applicable to iron and steel etc. not with the metal of alkali lye generation chemical reaction.Conventional alkaline cleaner has NaOH, Na2CO3, silicate, phosphoric acid salt etc., but each defectiveness of these alkali lye, such as NaOH is epistasis alkali lye, can react with acid dirt, but can only ferrous metal be used for, corrosive nature is had to non-ferrous metal, Na2CO3 belongs to medium tenacity alkali lye, ramollescence is had to hard water, but saponifying ability is weak, washing property is poor, although silicate widely uses non-ferrous metal and ferrous metal, but the H4SiO4 colloid produced easily is deposited on metallic surface, affect follow-up phosphatization quality, the phosphorus-containing wastewater of phosphate production is difficult to process, Water Eutrophication can be caused, also be subject to using restriction.The tensio-active agent that alkali lye degreasing is commonly used has anion active agent and tween, the de-oil mechanism of anion surfactant utilizes its absorption in metallic surface to form electrostatic double layer, increase the electromotive force of metal interface, be conducive to greasy dirt and depart from metallic surface, and not easily again polluted by greasy dirt.Nonionogenic tenside is that polar group is contained in molecular chain one end, and the other end contains a compounds of apolar chain, because its hydrophilic radical dissociation does not occur in aqueous, in neutral molecule, want stability high, be not subject to the impact of strong dielectric, potential of hydrogen.
Usually single anion surfactant is more, and its CMC concentration is high, and soil removability is strong, but stability is subject to solution medium and water quality impact comparatively large, and such as, in acidic medium, negatively charged ion will be converted into neutral molecule, and in water, solvability reduces; When water hardness is higher, easily generates insoluble material, its surfactivity is reduced.Therefore be necessary the alkaline cleaner developing a kind of environment-friendly type, use polynary complexed surfactant to realize the cleaning performance of more excellent more environmental protection, the corrodibility to equipment can be reduced.
Because clean-out system in the face of different cleaning objects or will will meet different cleaning objects in actual application, therefore, the using method of its correspondence is also not quite similar.To select according to concrete cleaning demand in actual cleaning process.
Summary of the invention
The object of the present invention is to provide a kind of alkaline cleaning fluid and preparation method of environment-friendly type.
The raw material composition of described alkaline cleaning fluid and each component dosage are: sodium hydroxide 5-15g/L, potassium hydroxide 5-10g/L, water glass 2.5-5g/L, Sunmorl N 60S 2-5g/L, phosphate amine salt 1-4g/L, trolamine 4-8g/L, polyoxyethylene oleate 4-10g/L, dodecyl hydroxypropyl phosphorate trimethyl-glycine 2-4g/L, dodecyl sodium lauroyl sareosine 5-12g/L, coconut diethanolamide 2-5g/L, poly-epoxy succinic acid 1-1.5g/L, benzotriazole 1.5-3g/L, all the other are deionized water.
