Abstract
The present invention relates to a cleaning agent, more specifically to a cleaning agent used for cleaning oil stain on the surface of ferrous metal powder. The present invention is prepared from 1 to 10 shares of Na2CO3, 1 to 5 shares of Na2SiO3, 0.3 to 2 shares of cleaning agent TX-10, 0.3 to 2 shares of n-butanol and 90 to 100 shares of water by parts by weight. By using the cleaning agent of the present invention, oil stain on the surface of nanometer powder can be cleaned. The cleaning rate of iron powder reaches 96% by detection, and the cleaning effect is good.
Description
Technical field
The present invention relates to a kind of clean-out system, specifically a kind ofly be used to clean ferrous metal powder surface smeary clean-out system.
Technical background
In cold-rolled steel is produced, produce a large amount of iron powders and be distributed in the emulsion, keep clean, with the iron powder in magnetic filter and filter paper or the filter cloth filtration emulsion in order to make emulsion, the iron powder that filters out has a large amount of ROLLING OIL, so filtration product is the mixture of iron powder and ROLLING OIL.The granularity of iron powder is very little, belongs to superfine iron powder, and very high economic worth is arranged, and wherein part is a nanometer iron powder, and its economic worth is higher.Therefore can not directly utilize because a large amount of oil is contained on the iron powder surface, the treatment process to filtration product is burning or buries, and has not only wasted resource but also contaminate environment.
Summary of the invention
Technical problem to be solved by this invention provides a kind of greasy dirt that can wash the iron powder surface off, obtains the ferrous metal powder clean-out system of clean nanometer iron powder.
The present invention adopts following technical scheme:
The present invention is made up of the component of following ratio of weight and number:

Water 100
Only need each component of the present invention is mixed in proportion, stirring gets final product.
Positively effect of the present invention is as follows: raw material is taken from the product after cold rolled sheet factory magnetic filters, and through the centrifugation pre-treatment, removes most of greasy dirt earlier.Each component of clean-out system of the present invention is prepared in proportion, stir.Through the pretreated raw material of centrifugation, 75 ℃ of washings 3 times, mechanical stirring, each washing time are followed successively by 125,35,35min with the washing of the clean-out system for preparing.Use clear water rinsing 4 times afterwards again, each mechanical stirring 10min.Each washing and rinsing all use the method for centrifugal settling with iron powder and liquid separation later.With the iron powder oven drying at low temperature that obtains, the clean rate that detects iron powder reaches 96% at last.Adopt clean-out system of the present invention can clean the greasy dirt on nanoscale powder surface, and cleaning performance is good.
Annotate: clean rate=(oil-contg of the water-content-iron powder of 1-iron powder)/(water-content of 1-iron powder)
