Description
Technical field
The invention belongs to magnetic devil liquor recovery process field, the magnetic flow liquid being modified more specifically to a kind of oleic acid
Recovery and treatment method.
Background technology
Magnetic flow liquid is in widespread attention with its distinctive magnetic rheology effect.Magnetic flow liquid is by the ferromagnetic of micron dimension
The suspension that property distribution of particles is formed in non magnetic liquid.Under the action of externally-applied magnetic field, performance (such as rheology of magnetic flow liquid
The performances such as, magnetics, mechanics, calorifics, optics) change rapidly, class solid-state is converted into by original sticky fluidised form, and have
Certain yield shear stress.The response time of magnetic rheology effect is very short, generally millisecond magnitude, and turn asked of mushy stage
Change has invertibity, and after external magnetic field removes, mobility can be recovered.The curing of magnetic flow liquid is strong and weak can be by externally-applied magnetic field
Control, its shear stress increase with the increase of magnetic field intensity, until reaching magnetic saturation state, in addition, magnetic flow liquid is also
Have the characteristics that energy consumption is relatively low, preparation is convenient, temperature applicable range is not wide, easy to pollute, led in automobile, machinery, building, aviation etc.
Domain is applied widely, and is considered most one of intellectual material of future.
Magnetic flow liquid is mainly made of following three parts：(1) the main discrete particles as dispersed phase；(2) it is used as dispersed phase
The basal liquid of carrier, also known as carrier fluid；(3) additive added for improvement rheomagnetic energy.Wherein main discrete particles mainly by
Magnetic-particle forms, and size mainly has micron and nanoscale.Magnetic-particle mainly has Fe3O4、Fe3N, Fe, Co, Ni or Fe, Co,
The particulate of the particulates such as Ni alloys, wherein magnetic saturation maximum is ferrocobalt, while further includes some other namagnetic substance, such as
Polystyrene or silica granule.For carrier fluid, including non magnetic carrier fluid and magnetic carrier fluid, non magnetic carrier fluid mainly has silicon at present
Oil, mineral oil, artificial oil, water and ethylene glycol etc.；Magnetic carrier fluid is mainly the less flowing molten iron body of grain diameter, is mainly used for disperseing
Receive, the particle of micron level.To ensure the suspension stability of particle and increasing the rheologic behavio(u)r of whole magnetic flow liquid, generally need
Additive is used, such as adds various surfactants or stabilizer, prevents particle precipitation and irreversible reunion.Live on surface
Property agent be usually the different structure composition of hydrophilic group and lipophilic group both properties oligomer, hydrophilic group adsorbed in suspended particulate
Surface, and the lipophilic group of one end is then diffused in as " tip of a whip " among nonpolar or polarity carrier fluid.Suspended particle absorbing control
After surfactant, due to " tip of a whip " mutually winding and repel, on the one hand can increase the volume of particle, reduce them and mutually inhale
Draw the chance of collision；On the other hand steric hindrance can be internally formed in carrier fluid, forms the three-dimensional net structure of an interaction,
Settled so as to reduce the particle caused by the density contrast of particle and carrier fluid.In addition, the addition of some additives can also change
" wetting " property of kind base fluid and solid particles surface, makes the bonding between particle few so as to reduce automatic cohesion.Oleic acid is to compare
A kind of common additive.For example, Chinese Patent Application No. is 201510113811.7, data of publication of application is July 15 in 2015
Day patent document disclose a kind of magnetic flow liquid with high conductivity and preparation method thereof, including following mass percent
Component：39.8%~90% carrier fluid, 0.2%~2% surfactant, 8%~60% Silver-coated Carbonyl Iron Powder；The invention prepares plating
Silver-colored carbonyl iron dust, using the method for chemical plating；The method that the invention prepares magnetic flow liquid is, by 39.8%~90% carrier fluid,
After 0.2%~2% surfactant is stirred evenly with mixer, 8%~60% Silver-coated Carbonyl Iron Powder is added, passes through reducing mechanism
When grinding 1~4 is small, magnetic flow liquid is prepared into, wherein surfactant is oleic acid, neopelex, stearic acid, bay
One or more combination in acid.
After long-time uses magnetic flow liquid, the consume of its magnetisable material and the denaturation of carrier fluid and additive, cause it
The index dramatic decrease such as mechanical property, magnetic performance, response time, most common method is replaces magnetic flow liquid at this time, by original
There is the discarding of degradation magnetic flow liquid.Because containing the carrier fluid of substantial amounts of ferromagnetic material, multiple compounds matter composition in magnetic flow liquid,
Complicated component, easily damages environment.So far, on non-to magnetic flow liquid device or method for recycling
Often few, Chinese Patent Application No. 201511025405.1, data of publication of application is that the patent application document on March 23rd, 2016 is public
