Description
Technical field
The present invention relates to a kind of washing composition, relate in particular to a kind of neutral rust cleaning washing composition.
Background technology
Metal gets rusty, as, it is a kind of very natural phenomenon that iron gets rusty, and still, is with becoming a serious problem to us.Because take a lot of the effort and works that money is built or moulder etc., waste.Simultaneously, corrosion of metal also can cause serious security incident.So preventing metallic corrosion is with making the equally very important thing of pure metal.
Usually the metallic corrosion of saying, we are appreciated that the process into metal return to the nature state.That is, corrode the process that is meant burning, when metal exposed was in air, the surface can form sull, and protection inside also keeps gloss.But moist when existing, negatively charged ion during the gas cyaniding thing, is easy to corrode, the MOX that formation throws into question to intensity and hardness aspect.Corrosion be and its contacted other metal between the electron migration process of being produced.Metal after the corrosion will lose original structure or characteristic, and the spontaneous corrosion process will cause financial loss, and annual invar iron rot causes the loss of more than 8,000 hundred million Renminbi, and about 20% is used for replacing the material that has got rusty in iron and steel of being produced and the metal.Usually in order in the environment that oxygen or moisture are arranged, to protect metal, lay a coat of paint from the teeth outwards or form the metal-plated rete.The material that metal can contact with the surface in different environment reacts, and makes it oneself become stable compound, and the oxide compound or the oxyhydroxide that are formed on the metallic surface because of this reason are called rust, because of this metal rust causes that the metallic surface consumes gradually.
Especially, can form sull on the surface of iron, make it become stable status.The structure of sull is that outside Fe → FeO → Fe3O4 → γ-Fe2O3 → α-Fe2O3 direction forms the higher structure of degree of oxidation from the lining.The red rust of iron is as 2Fe+O2=2FeO, 2Fe2O+2H2O=2Fe (OH) 2, and 4Fe (OH) 2+ can not adopt.
If the interfacial activity agent content is less than 0.2 weight %, the emulsification dispersion effect will be small, and when its content surpassed 8.0 weight %, because bubble-related issues will reduce marketability, the divergent function of emulsification simultaneously effect also can play retroaction.
Preferably: the preferred 3.0-10.0% of described macromolecular material, the preferred 0.5-5.0% of described interfacial agent.
Preferably: described interfacial agent is the emulsifying agent or the dispersion agent of negatively charged ion and nonionic system, at least a for verivates such as polyoxyethylene, sorbitanic class, amides and amines.
Preferably: described interfacial agent is at least a of verivates such as sorbitanic monoleate, sorbitanic list dodecyl RATE, dimethyl dodecyl amine oxide, Oleum Cocois alkyl dimethyl amine oxide, coco-nut oil fatty acid diethylolamine and coco-nut oil fatty acid monoethanolamine.
Preferably: described macromolecular material is at least a of semi-synthetic fibre cellulosic material, wetting ability synthesized polymer material or natural macromolecular material;
2H2O+O2=4Fe (OH) 3 through the existence of oxygen and moisture, forms oxide compound, because the structure of these rust is a porous matter, has the certain moisture performance, and sorptive power corrodes the salt or the gas of the amount of money easily, thereby can spread iron rust.After iron forms corrosion, with the Strength Changes that causes iron, for example, when in the thickness of iron 1% get rusty change after, intensity will reduce 5-10%.If this rust occurs in two sides 5% simultaneously, with causing the state that can't use fully.Get rusty in the comb in factory or building or form the minimizing that dirt causes the comb life-span, will become the major cause that increases energy expenditure and worsen water quality.
