Abstract
The invention discloses aqueous cleaning anti-rust agent, it is characterized in that: include abluent, nitrite, for regulating the additive of solution pH value, G & W, putting in water by described abluent, nitrite, glycerol, additive, stirring is mixed to form uniform solution.Present invention metal surface after cleaning ferrous metal forms one layer of complex, therefore completes the antirust treatment to ferrous metal after having cleaned simultaneously, eliminates the operation that oils, effectively reduce cost.
Description
Technical field
The present invention relates to a kind of cleaning rust-proof liquid.
Background technology
Ferrous metal after cleaning, for preventing surface corrosion, it is necessary to carry out without application antirust treatment, such as, applies antirust agent on surface.Prior art metal surface is antirust, has the preferable antirust oil of rust-proof effect compared with early using, and forms protective oil film by antirust oil in metal surface, and in isolation air, steam is to corrosion of metal, thus it is antirust to reach the long period.But use antirust oil, not only need to consume substantial amounts of oil plant raw material, exacerbate energy resource consumption, and in following process (such as weld, paint, electroplate, assemble) and unpacking, it is required to clean oil removing, not only produces a large amount of oily waste liquor that cleans and discharge, cause the pollution to environment, and it is time-consuming to clean oil removing, also can increase cost.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of aqueous cleaning rust-proof liquid so that traditional need ferrous metal is cleaned after oil two procedures become cleaning after the most antirust, therefore eliminate the operation that oils, decrease the input of the equipment of oiling.
The present invention is achieved through the following technical solutions: aqueous cleaning anti-rust agent, it is characterized in that: include abluent, nitrite, for regulating the additive of solution pH value, G & W, putting in water by described abluent, nitrite, glycerol, additive, stirring is mixed to form uniform solution.
Described additive is any one or a combination thereof in disodium hydrogen phosphate, sodium carbonate, sodium bicarbonate.
In described aqueous cleaning anti-rust agent, each component has a following mass ratio: abluent: 1%～5%, nitrite: 3%～7%, glycerol: 1%～5%, additive: 3%～7%, water: 76%～92%.
There is advantages that metal surface forms one layer of complex after cleaning ferrous metal, therefore completes the antirust treatment to ferrous metal after having cleaned simultaneously, eliminates the operation that oils, effectively reduce cost.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail: embodiment 1: aqueous cleaning anti-rust agent, including abluent, nitrite, for regulating the additive of solution pH value, G & W, described abluent, nitrite, glycerol, additive are put in water, stirring is mixed to form uniform solution, and described additive is disodium hydrogen phosphate.
In described aqueous cleaning anti-rust agent, each component has a following mass ratio: abluent 1%, nitrite 3%, glycerol 1%, additive 3%, water 92%.
This aqueous cleaning anti-rust agent, the mass ratio of various components (in addition to water) is little, and therefore production cost is low, and has preferable cleaning rust-proof effect.
Embodiment 2: aqueous cleaning anti-rust agent, including abluent, nitrite, for regulating the additive of solution pH value, G & W, described abluent, nitrite, glycerol, additive are put in water, stirring be mixed to form uniform solution.
Described additive is any one or a combination thereof in disodium hydrogen phosphate, sodium carbonate, sodium bicarbonate.
Described composition has a following mass ratio: abluent 5%, nitrite 7%, glycerol 5%, additive 7%, water 76%.
This aqueous cleaning anti-rust agent, implementation cost is higher, and cleaning rust-proof effect is general.
Embodiment 3: aqueous cleaning anti-rust agent, including abluent, nitrite, for regulating the additive of solution pH value, G & W, described abluent, nitrite, glycerol, additive are put in water, stirring be mixed to form uniform solution.
Described additive is any one or a combination thereof in disodium hydrogen phosphate, sodium carbonate, sodium bicarbonate.
Described composition has a following mass ratio: abluent 3%, nitrite 5%, glycerol 3%, additive 5%, water 84%.
Each component reasonable mixture ratio in embodiment 3, need not too high implementation cost while ensureing cleaning rust-proof effect.
Glycerol in the present invention: can be the most miscible with water, is mainly used in reducing the freezing point of water, prevents cleanout fluid from easily freezing when using in the case of temperature is relatively low.
Additive, is mainly used as the pH value regulation of solution, typically uses disodium hydrogen phosphate, it is ensured that solution can be in alkalescence, and disodium hydrogen phosphate is colourless monoclinic system crystal or white powder, is dissolved in water, and its aqueous solution is alkalescence, and the pH value of 1% aqueous solution is 8.8～9.2；Can be as the stabilizer of solution in this agent, it is ensured that solution pH value is between 8-10.
Abluent, is configured to by surfactant (such as sodium alkyl benzene sulfonate, sodium alkyl sulfate) and various auxiliary agent (such as sodium tripolyphosphate), adjuvant, has well infiltration, moistening, dispersion, emulsifiability, the advantages such as soil release performance is strong, price is low.
Nitrite, mainly uses sodium nitrite, sodium nitrite to generate the film (oxide-film) of protected effect with metal, and anode region is protected in the oxide covering generating indissoluble on the metal surface, causes the increase of anode polarization, thus suppresses the anodic process of metal.
