Abstract
The invention discloses a metal surface cleaning agent and a using method, and relates to a cleaning agent and a using method thereof for aluminum and aluminum alloy, zinc and zinc alloy, steel and chromium alloy surfaces. The metal surface cleaning agent consists of the following components in percentage by mass: 45% of sodium carbonate, 40% of trisodium phosphate, 10% of sodium gluconate and 5% of a nonionic surfactant NP-6. In use, the metal surface cleaning agent is prepared into a cleaning solution for the cleaning of a metal surface. The cleaning agent disclosed by the invention does not contain silicate, is good in cleaning effect, and does not corrode the aluminum and the aluminum alloy surfaces, and therefore, further processing performance such as bonding performance, welding performance, anodic polarization or sealing performance and the like are not affected.
Description
Technical field
A kind of metal surface cleaning agent and using method, relate to a kind of for Al and Alalloy, zinc and zinc alloy, the clean-out system on iron and steel and Chrome metal powder surface and using method.
Background technology
At present, conventional Al and Alalloy, zinc and zinc alloy, the surface cleaning agent on iron and steel and Chrome metal powder surface, mostly containing silicate, because silicate has corrosion to piece surface, toxicity is large, because clean-out system contains the clean-out system (because the cloud point impact of silicate Surfactant is very large) that silicate is difficult to be made into high density, and liquid is difficult to process after cleaning, cause environmental-protecting performance poor, energy consumption and cost high, its surperficial grease can not be removed completely.
Summary of the invention
Object of the present invention is exactly the deficiency existed for above-mentioned prior art, provide a kind of without silicate, fast, nontoxic, the good environmental protection of cleaning speed, can not the metal surface cleaning agent on resistant alloy surface and using method.
The object of the invention is to be achieved through the following technical solutions.
A kind of metal surface cleaning agent, it is characterized in that the mass percent of its clean-out system consists of: soda ash 45%, tertiary sodium phosphate 40%, Sunmorl N 60S 10%, nonionic surface active agent NP-6 is 5%.
A kind of metal surface cleaning agent of the present invention, each Component Use is as follows: 1. soda ash: the grease on cleaning components surface, ensures that solution maintains certain alkalinity ranges in oil removal process.2. tertiary sodium phosphate: washing assistant, the grease on cleaning components surface, has infiltration and emulsifying effect, can increase the wetting ability of water, have certain emulsifying effect.3. Sunmorl N 60S: washing assistant, the grease on cleaning components surface, makes coating thing and workpiece surface mortise.4. nonionic surface active agent NP-6: the tensio-active agent not producing ion in aqueous, has excellent emulsification, washing function, stronger to each quasi-grease cleansing power.
The using method of a kind of metal surface cleaning agent of the present invention, when it is characterized in that using, is mixed with scavenging solution by metal surface cleaning agent, carries out cleaning metal surface.
Cleaning is stirred: machinery or slight pneumatic blending, cell body material: iron and steel, workpiece lifting capacity 0.8 ~ 2dm
2/ L.
The using method of a kind of metal surface cleaning agent of the present invention, when it is characterized in that using, the detergent concentration of the scavenging solution be mixed with: 20 ~ 50g/L, temperature: 50 ~ 80 DEG C, soaking and washing time 1 ~ 15min.
The using method of a kind of metal surface cleaning agent of the present invention, when it is characterized in that using, the detergent concentration of the scavenging solution be mixed with is 50g/L, and temperature is 60 DEG C.
The using method of a kind of metal surface cleaning agent of the present invention, is characterized in that the step preparing scavenging solution preparation is as follows: 1. in rinse bath, add 1/2 volumes of deionized water; 2. add clean-out system to stir until dissolve completely; 3. adding deionized water to prescribed volume is heated to service temperature.
The using method of a kind of metal surface cleaning agent of the present invention, is characterized in that concentration of lotion detection method is as follows: 1. get 5mL sample, adds several methyl orange indicators; 2. terminal is titrated to 0.5N sulfuric acid; 3. detergent concentration (g/L)=18.52 × sulfuric acid volume (mL).
A kind of metal surface cleaning agent of the present invention, is not only applicable to slough Al and Alalloy surface grease, is also applicable to process zinc, and iron and steel and Chrome metal powder surface grease, also can be used for the precision work compound removing piece surface; Clean-out system can not corrode Al and Alalloy surface, therefore can not affect the further processing characteristics of part, such as, cohere, welding, anodic polarization or sealing, this clean-out system is one not silicate clean-out system, and cleaning performance is good, can not corrode Al and Alalloy surface, therefore further processing characteristics can not be affected, such as cohere, welding, anodic polarization or sealing property.
