Abstract

The present invention belongs to metal surface treatment, particularly to cleaning and degreasing treatment of the surface of stainless steel. A degreasing agent for cleaning stainless steel contains 4 to 12 shares of phosphoric acid, 0.2 to 1.5 shares of sodium alkyl benzene sulfonate, 0.2 to 1.5 shares of sodium dodecylbenzene sulfonate, 0.1 to 1 share of OP-10 emulsifier and water as the rest. The present invention is especially suitable for cleaning and degreasing significant chemical industry equipment of stainless steel materials, pipelines, containers, etc., the cleaned and degreased surface of the stainless steel is glossy without erosion. The present invention has the advantages of small influence of acid and alkali, soft water, hard water and seawater, strong degreasing capability, favourable cleaning effect, no toxicity and difficult combustion, and thus, the present invention has the extensive prospect of application.

Description

Degreasing agent for cleaning stainless steel
Technical field:
The invention belongs to metal finishing, particularly the cleaning and degreasing of stainless steel surface is handled.
Background technology:
Metal and goods thereof are in the course of processing or after using for some time; regular meeting is at various dirts of surface contamination and impurity; so cleaning is an extremely important content in the metal finishing; especially stainless material, pipeline, container all are important chemical equipment, and clean becomes very necessary operation for this reason.Cleaning generally needs first degreasing, pickling then, passivation.The purpose of degreasing is to remove the metallic surface at the grease of rolling, producing in the making, installation process, and pickle solution can slap-uply be contacted with the metallic surface, thus the quality of assurance pickling and passivation.
With the degreasing is the cleaning and degreasing agent commonly used of main purpose, and it is cleaning and degreasing agent that oil is generally arranged, chloro hydrocarbon system cleaning and degreasing agent, alkaline cleaning and degreasing agent and the cleaning and degreasing agent that contains tensio-active agent.What metal finishing mostly adopted is alkaline cleaning and degreasing agent.This cleaning and degreasing agent mainly is melted in the water by sodium hydroxide, yellow soda ash, water glass, sodium phosphate etc., becomes alkaline cleaning and degreasing agent.Their principle be with greasy dirt in fatty acid glycerine fat generation saponification form nascent soap, make greasy dirt become water-soluble and dissolved removal.Because low, the nontoxicity of its price, nonflammable use are comparatively extensive.But for stainless steel, because stainless surface itself has layer protecting film, sodium hydroxide has erosion action to protective membrane, degreasing Hou surface dulling, and degreasing is not thorough, and effect is not ideal enough, makes the quality of subsequent handling can not get guaranteeing.The more important thing is that stainless steel after the sodium hydroxide degreasing using one section Hou, the embrittlement phenomenon takes place easily, cause the inefficacy of stainless steel equipment.
Summary of the invention:
The objective of the invention is to avoid the deficiencies in the prior art part and a kind of degreasing agent for cleaning stainless steel is provided.
Purpose of the present invention can be by realizing by the following technical solutions: a kind of degreasing agent for cleaning stainless steel, contain phosphatase 24-12 part, and sodium alkyl benzene sulfonate 0.2-1.5 part, Sodium dodecylbenzene sulfonate 0.2-1.5 part, OP-10 emulsifying agent 0.1-1 part, all the other are water.(all each component content sums are 100% in the composition.)
It is technical pure that the present invention adopts phosphoric acid, under acidic conditions and the fatty acid glycerine fat generation saponification in the greasy dirt form nascent soap, make greasy dirt become water-soluble and dissolved removal, simultaneously there is phosphorization on stainless surface, can suppress corrosion, make it surface is glossy and do not send out crow.Adopt tensio-active agent Sodium dodecylbenzene sulfonate, the wettable stainless steel surface of sodium alkyl benzene sulfonate, enter the interface that stainless steel is connected with dirt, dirt is opened, perhaps make the lipid dirt with conglobulation on stainless steel surface, come off from stainless steel surface gradually then, disperse or suspend into fine particle, this fine particle is dissolved as solution or is adsorbed on capsule surface in the capsule of clean-out system, form emulsion or dispersion liquid with water, and be unlikely to aggegation or be adsorbed on stainless steel surface, influence cleaning performance.
Described degreasing agent for cleaning stainless steel also contains JFC detergent 0.1-1 part.
The present invention also contains inhibiter 1-5 part.
The invention has the beneficial effects as follows:
1. the present invention is specially adapted to the cleaning and degreasing of important chemical equipment such as stainless material, pipeline, container, and the cleaning and degreasing rear surface is glossy does not send out crow, to the no erosion action in stainless surface.
2. it is less that the present invention is subjected to the influence of soda acid, soft or hard water, seawater, and the degrease ability is strong, and cleaning performance is good.Nontoxic, nonflammable, thereby wide application prospect is arranged.
3. easy to use.
4. recyclable recycling reduces and pollutes, and reduces and cleans cost.
