Abstract
The invention discloses a ferrite stainless steel surface conditioning agent, which is composed of the following raw materials in percentage by weight: 5 to 35% of organic acid, 3.0 to 25% of nitrides, 15 to 35% of alkaline salts, 0.5 to 8.0% of surfactant, 0.5 to 8.0% of corrosion inhibitor, and the balance being water. The production method comprises the following steps: under a normal pressure, adding water into a container at a room temperature, then adding a surfactant, a corrosion inhibitor, and an organic acid, stirring to completely dissolve the components, then adding nitrides and alkaline salts, stirring to completely dissolve the components, stopping stirring, and packaging.
Description
Technical field
The present invention relates to field of fine chemical, especially a kind of with low cost, for the ferritic stainless steel surface treatment agent that processes ferritic stainless steel metallic surface and production method.
Background technology
In ship's gear production, need to process ferritic stainless steel fastener surface, the tawny zone of oxidation of appearance is removed, and ensure not corrode, do not change virgin metal true qualities, existing ferritic stainless steel surface treatment agent cost is higher, urgently to be resolved hurrily.
Summary of the invention
The present invention is to solve above-mentioned technical problem existing for prior art, provide a kind of cheap, for the ferritic stainless steel surface treatment agent that processes ferritic stainless steel metallic surface and production method.
Technical solution of the present invention is: a kind of ferritic stainless steel surface treatment agent, it is characterized in that raw materials used and weight percent is as follows:
Organic acid 5 ~ 35%
Nitride 3.0 ~ 25%
Basic salt 15 ~ 35 %
Tensio-active agent 0.5 ~ 8.0 %
Inhibiter 0.5 ~ 8.0 %
Water surplus.
A kind of production method of above-mentioned ferritic stainless steel surface treatment agent, it is characterized in that carrying out in accordance with the following steps: under normal temperature and pressure, add water in container after, add tensio-active agent, inhibiter, organic acid again, stir after all dissolving each other, add nitride and basic salt, stir complete molten rear stopping and stirring, enter packet assembler.
The present invention is the ferritic stainless steel surface treatment agent prepared by the formula of science, retrofit, ferritic stainless steel surface tawny oxide compound can not only be removed rapidly, but also passivation layer can be formed at stainless steel surface, burn into does not change stainless steel true qualities, and key is with low cost.
Embodiment
