Abstract
The invention discloses a cleaning agent for recycling iron powder from a magnetic filtered product in a cold rolling plant. The cleaning agent comprises components including, in weight percent, 0.1-1% of TX-10, 0.1-1% of AEO-9, 0.01-1% of fluorine containing surfactant, 0.5-5% of Na2SiO3, 0.01-1% of EDTA (ethylene diamine tetraacetic acid), 0.01-0.2% of n-butyl alcohol and the balance water. By the aid of the technical scheme, the cleaning agent has the advantages that the cleaning agent is a water-based metal cleaning agent, excessively high cleaning temperature is omitted, greasy dirt on the surface of the iron powder can be rapidly removed, cleaning time is shortened, and the content of iron in the obtained iron powder is high. Therefore, the cleaning agent has the advantages of low cleaning temperature and less consumption.
Description
Technical field
The present invention relates to a kind of cleaning agent, especially a kind of cleaning agent that is used for reclaiming cold rolling mill magnetic filtrate iron powder.
Background technology
Can produce a lot of tiny iron powders and continuous the entering in the emulsion in the flat cold-rolled sheet production process, keep clean, adopt magnetic filter to remove the iron powder in the emulsion for making emulsion.Iron powder size in the cold rolling mill magnetic filtrate has higher economic value at nanoscale after deliberation.Cold rolling mill magnetic filtrate is the mixture of iron powder and ROLLING OIL, and iron powder is wrapped up by greasy dirt, can only carry out burn processing or bury as fuel oil, not only contaminated environment but also waste resource.
Summary of the invention
The technical problem that the present invention will solve provides a kind of cleaning agent that is used for reclaiming cold rolling mill magnetic filtrate iron powder that can remove iron powder surface and oil contaminant in the cold rolling mill magnetic filtrate effectively.
For solving the problems of the technologies described above, the present invention is made up of the component of following weight percent: TX-10 0.1～1%, AEO-9 0.1～1%, fluorine-containing surfactant 0.01～1%, Na
2SiO
30.5～5%, EDTA 0.01～1%, n-butanol 0.01～0.2%, surplus is a water.
Fluorine-containing surfactant of the present invention is FN-6810.
The present invention is contemplated that: the performance that single surfactant does not have can appear in the composite of different surfaces activating agent in system, as producing cooperative effect and synergistic effect.TX-10 (APES in this cleaning agent; Have another name called: NPE), can reduce the total consumption of surfactant greatly behind the AEO-9 (AEO), three kinds of surfactant compounds of fluorine-containing surfactant; Promptly reduced the content of organic substance in the cleaning agent; Alleviate the burden of wastewater treatment, improved the cleaning agent clean effect again.The adding of other auxiliary agents can be played dispersion, and the is anticorrosion effect of Denging.The content of surfactant is difficult for too much in the cleaning agent, if excessive then increase the viscosity of solution, influence the dispersion of iron powder, the reduction cleaning performance; If the content of surfactant is low excessively, the subcritical micellar concentration does not then have cleaning action, can not remove greasy dirt.Composition of the present invention and proportioning thereof are through creative work and test in a large number and obtain.
Adopt the beneficial effect that technique scheme produced to be: this cleaning agent is a water base metal cleaning agent, does not need too high cleaning temperature; This cleaning agent can be peeled off removal to the greasy dirt on iron powder surface fast, shortens scavenging period, and obtains iron content height in the iron powder.Therefore, cleaning agent of the present invention has the advantages that cleaning temperature is low, consumption is few.
The specific embodiment
Below in conjunction with specific embodiment the present invention is done further detailed explanation.
Embodiment 1-9: the cleaning agent that originally is used for reclaiming cold rolling mill magnetic filtrate iron powder is by TX-10, AEO-9, FN-6810 (fluoroalkyl alcohol APEO), Na
2SiO
3, EDTA (ethylenediamine tetra-acetic acid), n-butanol and water, mixing and stirring forms.
Washing methods: raw material is taken from the magnetic filtrate of certain cold rolling mill, after centrifugal, removes most of ROLLING OIL.Each component of cleaning agent is prepared in proportion, stir.Get a certain amount of raw material with the washing of this cleaning agent, ultrasonic and mechanical agitation, supersonic frequency 40KHz, power density 0.44W/cm
2, 40 ℃ of temperature, scavenging period is 20 min, repeats to clean 4 times with this cleaning agent, uses rinsed with deionized water up to clarification of water afterwards again.The each cleaning with rinsing all uses the method for magnet sedimentation that iron powder is separated with liquid (this washing agent, deionized water) later.With the iron powder low temperature drying that obtains, with GB/T 3049-2006 1,10-ferrosin AAS detects the iron content of iron powder at last.
The percentage by weight of each component and the iron powder iron content after washing is seen table 1 among the embodiment.
Claims (2)
1. a cleaning agent that is used for reclaiming cold rolling mill magnetic filtrate iron powder is characterized in that, its component by following weight percent is formed: TX-10 0.1～1%, AEO-9 0.1～1%, fluorine-containing surfactant 0.01～1%, Na
2SiO
30.5～5%, EDTA 0.01～1%, n-butanol 0.01～0.2%, surplus is a water.
2. the cleaning agent that is used for reclaiming cold rolling mill magnetic filtrate iron powder according to claim 1 is characterized in that: described fluorine-containing surfactant is FN-6810.
