Abstract
The invention provides chromium-containing treating fluid for stabilization of a bare steel rust layer. The chromium-containing treating fluid is composed of, by weight, 0.5%-5% of sodium bichromate, 0.1%-3% of NaHSO3, 0.1%-2% of FeSO4, 0.1%-2% of FeCl3, 0.1%-1% of acetic acid, 0.1%-0.5% of triethanolamine, and the balance water. The chromium-containing treating fluid has good performance of preventing sagging of rust fluid; after the chromium-containing treating fluid is sprayed on the surface of a weathering resistant steel plain sample with oxide scale being removed, formation of a stable rust layer is promoted, and the rust layer has good corrosion resistance and is suitable for coating of bare steel.
Description
Technical field
The invention belongs to metal protection technical field, specifically refer to a kind of for naked steel rusty scale stable containing chromium treatment solution.
Background technology
Metallic corrosion is a kind of failure procedure of metal under the effect of environmental corrosion medium, and being a kind of completely spontaneous inevitable spontaneous phenomenon of carrying out, is the inverse process of metallurgical production.Atomospheric corrosion causes the major reason of the early failures such as product, unit, structural part and destruction.The financial loss caused because of atomospheric corrosion is every year very surprising.Under air physical environment, it is a step-by-step procedure that naked steel forms stable protection rusty scale, needs considerable time, more than at least 3 years, and the naked steel surface had forms the time of form compact and stable rusty scale more than more than 10 years.Stablize in the process of rusty scale in formation, usually occur early stage rust liquid sagging and disperse polluting the phenomenon of surrounding environment.And the process of the rusty scale surface of stability carries out chemical treatment to naked steel surface exactly, directly generate stable fine and close rusty scale, form self-protection.After coating rusty scale surface of stability treatment agent, naked steel both can be avoided to use the phenomenon of initial stage yellow rust liquid sagging, preventing pollution, and stable protective rust can have been formed rapidly on its surface again, the corrosion speed of naked steel is tended towards stability.
Summary of the invention
The object of the present invention is to provide a kind of for naked steel rusty scale stable containing chromium treatment solution, effectively can solve naked steel rusty scale stabilization and rust liquid flowing down problems.
For achieving the above object, designed by the present invention for naked steel rusty scale stable containing chromium treatment solution, its special special character is, should be containing weight percent of each component in chromium treatment solution: sodium dichromate 99 is 0.5 ~ 5%, NaHSO
3be 0.1 ~ 3%, FeSO
4be 0.1 ~ 2%, FeCl
3be 0.1 ~ 2%, acetic acid is 0.1 ~ 1%, trolamine is 0.1 ~ 0.5%, all the other are water.
Further preferably, should be containing weight percent of each component in chromium treatment solution: sodium dichromate 99 is 2.1 ~ 2.9%, NaHSO
3be 1.1 ~ 2.2%, FeSO
4be 0.8 ~ 1.4%, FeCl
3be 0.7 ~ 1.5%, acetic acid is 0.3 ~ 0.8%, trolamine is 0.2 ~ 0.3%, all the other are water.
Again further, should be containing weight percent of each component in chromium treatment solution: sodium dichromate 99 is 2.6%, NaHSO
3be 1.4%, FeSO
4be 1.0%, FeCl
3be 0.9%, acetic acid be 0.5%, trolamine is 0.3%, water 93.3%.
The contain chromium treatment solution mechanism of action stable for naked steel rusty scale of the present invention is:
Containing in chromium treatment solution, the generation adding alpha-feooh in promotion rusty scale of sodium dichromate 99, Cr can generate stable α-(Fe by aliquot replacement alpha-feooh
