Description

A kind of the recovery processing agent and its application method of the magnetorheological fluid that oleic acid is modified
Technical field
The invention belongs to be machined devil liquor recovery technical field, more specifically to a kind of modified magnetic current of oleic acid Become the recovery processing agent and its application method of liquid.
Background technique
Magnetorheological fluid (Magnetorheological Fluid, abbreviation MR fluid) belongs to controlled fluid, is in intellectual material Study more active one.Magnetorheological fluid is by high magnetic permeability, low hysteresis small soft magnetic particles and non-magnetic liquid The suspended substance that body mixes.Magnetorheological fluid is in widespread attention with its distinctive magnetic rheology effect.Magnetorheological fluid is by micro- The ferromagnetic particle of rice magnitude is distributed in the suspension formed in non magnetic liquid.Under the action of externally-applied magnetic field, magnetorheological fluid Performance (such as rheology, magnetics, mechanics, calorifics, optics performance) change rapidly, be converted by original sticky fluidised form Class solid-state, and there is certain yield shear stress.The response time of magnetic rheology effect is very short, generally millisecond magnitude, and The conversion of mushy stage asked has invertibity, and after external magnetic field removes, mobility can be restored.The solidification of magnetorheological fluid is strong and weak It can be increased by the control of externally-applied magnetic field, shear stress with the increase of magnetic field strength, until reach magnetic saturation state, except this it Outside, magnetorheological fluid also has the characteristics that energy consumption is lower, preparation is convenient, temperature applicable range is not wide, easy to pollute, automobile, machinery, The fields such as building, aviation are applied widely, and are considered one of the intellectual material of most future.Magnetorheological fluid is mainly by following Three parts composition: (1) as the main discrete particles of dispersed phase；(2) basal liquid as dispersed phase carrier, also known as carrier fluid；(3) it is The additive for improving rheomagnetic energy and being added.Wherein main discrete particles are mainly made of magnetic-particle, and size mainly has micron And nanoscale.Magnetic-particle mainly has Fe3O4、Fe3N, the particles such as Fe, Co, Ni or Fe, Co, Ni alloy, wherein magnetic saturation is most Big particle is ferrocobalt, while further including some other namagnetic substance, such as polystyrene or silica granule.For carrying Liquid, including non magnetic carrier fluid and magnetic carrier fluid, non magnetic carrier fluid mainly has silicone oil, mineral oil, synthetic oil, water and ethylene glycol at present Deng；Magnetic carrier fluid is mainly the lesser flowing molten iron body of grain diameter, be mainly used for dispersion receive, the particle of micron level.
To ensure the suspension stability of particle and increasing the rheologic behavio(u)r of entire magnetorheological fluid, generally require using addition Various surfactants or stabilizer is such as added in agent, prevents particle precipitating and irreversible reunion.Surfactant is usually The oligomer of the different structure composition of both properties of hydrophilic group and lipophilic group, hydrophilic group are adsorbed on the surface of suspended particulate, and The lipophilic group of one end is then diffused in nonpolarity or polar carrier fluid as " tip of a whip ".Suspended particle absorbing control surfactant After, due to " tip of a whip " mutually winding and repel, on the one hand will increase the volume of particle, reduces them and attract each other the machine of collision Meeting；On the other hand steric hindrance can be formed inside carrier fluid, formed one interaction three-dimensional net structure, thus reduce by The sedimentation of the particle caused by the density contrast of particle and carrier fluid.In addition, the addition of some additives can also improve base fluid and consolidate " wetting " property of body particle surface keeps the bonding between particle few to reduce automatic cohesion.Oleic acid is more commonly used one kind Additive.For example, Chinese Patent Application No. is 201510113811.7, data of publication of application is the patent text on July 15th, 2015 Part discloses a kind of magnetorheological fluid and preparation method thereof with high conductivity, includes the following components'mass percentage: 39.8%~90% carrier fluid, 0.2%~2% surfactant, 8%~60% Silver-coated Carbonyl Iron Powder；The invention prepares silver-plated carbonyl Base iron powder, using the method for chemical plating；The method that the invention prepares magnetorheological fluid is, by 39.8%~90% carrier fluid, 0.2%~ 2% surfactant with mixing machine after mixing evenly, be added 8%~60% Silver-coated Carbonyl Iron Powder, by grinding device grinding 1~ 4 hours, it is prepared into magnetorheological fluid, wherein surfactant is oleic acid, in neopelex, stearic acid, lauric acid One or more combination.
After long-time uses magnetorheological fluid, the consume of magnetisable material and the denaturation of carrier fluid and additive lead to it The indexs dramatic decrease such as mechanical property, magnetic performance, response time, the most common method is replacement magnetorheological fluid at this time, will be former There is the discarding of degradation magnetorheological fluid.Because containing the carrier fluid of a large amount of ferromagnetic material, multiple compounds matter composition in magnetorheological fluid, Complicated component is easy to cause damages to environment.So far, non-about the device or method being recycled to magnetorheological fluid 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 Opened a kind of magnetorheological fluid recyclable device and its control method and component manufacturing method, it include inlet stop valve, upper housing, under Shell, electro static filtering plate, upper adsorption tube, lower adsorption tube, ribbed pipe, coil, heater, blender, pump, return pipe, outlet cut-off Valve；The upper housing and lower case is bolted, and sealing ring, the inlet stop valve setting is arranged in joint place On upper housing；The invention simultaneously additionally provides the manufacturing method of its control method and critical component, which passes through electrostatic mistake The preliminary treatment to mixed liquor is completed in the filtering of filter plate, suction-operated, in recycling adsorption tube, lower adsorption tube and ribbed pipe adsorb into One step completes the processing to mixed liquor, and adds heater, blender and the circulatory system, reaches magnetisable material and solvent is thorough Isolated purpose.But the recyclable device of the invention can only carry out preliminary magnetisable material separation to magnetorheological fluid, cannot reach Really recovery processing and utilization are still very big to the pollution of environment.
Therefore it is badly in need of developing corresponding recovery and treatment method, discarded magnetorheological fluid is handled, can not only be reduced Pollution to environment, and related substances therein can be recycled, save the energy.
