Description
Technical field
The present invention relates to a kind of physics--the conventional method of chemistry, particularly relates to a kind of fixed reactor with inner moving meter.
Background technology
Mechanical force and chemical is as an emerging frontier branch of science, and it is multidisciplinary, multi-field that its theory relates to Solid-state Chemistry, powder science, mechanical engineering etc.Mechanical force causes lattice relaxation and structure cracking, inspires high energy electron and plasma.Mechanical force and chemical likely carries out the reaction that heat chemistry under normal circumstances can not be carried out, and the thermal chemical reaction speed of solid matter is reduced, and reaction speed is accelerated.Two is mineral grains because producing lattice defect, crystal transfer and decrystallized in superfine grinding process, and produce the reasons such as unsaturated bond, free ion and electronics because of surface chemistry bond fission, cause increasing in mineral crystal, and the crackle that material inside develops rapidly makes its tip temperature and pressure increase, and finally causes the equilibrium constant of substance reaction and rate constant to enlarge markedly.
Mechanical force and chemical, the heterogeneous chemical reaction process of being participated in by solid phase, is reach atom level between reactant to combine, overcome reaction barrier and the process of chemical reaction occurs, is characterized in having interface to exist between reactant.The factor affecting reaction speed responds the Gibbs free of process, temperature, interfacial characteristics, diffusion velocity and thickness of diffusion layer etc.Powder particle is in Process During High Energy Ball Milling, and Mechanosensitive channels makes lattice dot matrix aligning part lose periodically, forms lattice defect, distortion of lattice occurs.Powder particle, by intense plastic strain, produces stress and strain, and produce a large amount of defects in particle, particle is decrystallized.This significantly reduces the diffusion activation energy of element, make at room temperature significantly to carry out atom or ion diffuse between constituent element; The continuous cold welding of particle, fracture, structure refinement, define countless diffusion/reaction even, and diffusion length also shortens greatly simultaneously.Stress, strain, defect and a large amount of nanometer crystal boundary, phase boundary produce, and make system stored energy very high (reaching tens kJ/mol), powder activity improves greatly, even brings out heterogeneous chemical reaction.Achieve cryochemistry reaction at present in many systems, successfully synthesize novel substance, by powder particle and abrading-ball acute impact, collide and make powder particle cold welding, fracture repeatedly, the method of the mechanical force and chemical operation principle causing powder granule Atom to spread has had commercial prod, and dispersion aluminium alloy is exactly wherein a kind of.
The kinetics mechanism of mechanical force and chemical is that in process of lapping, mechanical force is to material with actings such as compression, impact, friction, extruding, shearing and extensions, and changes mechanical energy is chemical energy and changes mechanical energy is heat energy, and changes mechanical energy is that heat energy can form high temperature.Have document to record, the people such as Urakaec adopt nonlinear elastic theory (Hertz is theoretical) to calculate, and may produce instantaneous (10 in the mechanical force and chemical process in planetary ball mill
-9~ 10
-8s) high temperature (1000k), and high pressure (1 ~ 10GPa).The people such as Heinick find by controlling the experiment of high pressure vibration wave, when pressure is 13GPa, 20GPa, can produce 4 × 10 respectively
-3, 8 × 10
-3lattice deformability amount.In mechanical milling process, particle surface stressed particle temperature is more much higher than measured macro-temperature.The people such as Ermakov think, in mechanical milling process, the stressed particle of particle surface produces violent plastic deformation, even may produce melting effect.Changes mechanical energy be heat energy formed high temperature, High Pressure is in chemical process.
Due to mechanical force and chemical be compress, impact, rub, extrude, shear, the mechanical energy such as extension realizes cold welding, fracture, structure refinement, formation diffusion/reaction is even, high temperature, high pressure reach mechanical force and chemical process object, and mechanical milling process just must have high energy to ensure enough impulsive forces, compression stress and frictional force.
Existing ball mill is adopted at existing machinery power Practical in Chemistry great majority, existing ball mill operation principle is the pulverizing that ball-milling medium collision energy causes material, collision is caused by the gyration of cylindrical shell, energy transferring is given by the material of grinding by the collision of repeatedly varying strength and frequency by the ball-milling medium of ball mill, but, and the collision of not all can cause the pulverizing of material, the collision that part energy intensity is large, only this part energy is used for pulverizing, and the collision that energy intensity is little is not enough to the pulverizing causing material.
Analysis shows, the ball-milling medium collision energy of ball mill is relevant with ball mill ball-milling medium kinetic characteristic.The basis of ball mill ball-milling medium motion analysis is the separation angle calculating ball-milling medium and rotary barrel inwall:
In formula, θ * is ball-milling medium moved apart angle in ball grinding cylinder, and R is inner wall of rotary drum radius, and n is drum rotation speed (rev/min).
It is larger that above formula gives angle of departure θ *, and the coefficient of friction that the relative motion of ball-milling medium and ball grinding cylinder produces is larger, and grinding efficiency will be higher, and this have ignored the gliding motility of ball-milling medium on the circular arc inwall of ball grinding cylinder in fact.The gliding motility of ball-milling medium on the circular arc inwall of ball grinding cylinder is almost inoperative to the pulverizing of material.This is that existing ball mill exists the low main cause of energy efficiency coefficient.
Due to the gliding motility of ball-milling medium on the circular arc inwall of ball grinding cylinder, result in the target increasing ball-milling medium moved apart angle θ * in ball grinding cylinder and be difficult to realize in engineering.Existing ball mill energy efficiency coefficient is low causes the preparation of many employing ball-milling technology materials to need the at substantial time.Document is recorded, the people such as Nikaido, crystal structure in order to modified kaolin and alumag reaches mechanical property to mullite sintered body and hot property, through the ball milling of 192 hours, crystal structure is unformed shape by crystalline transformation, and the formation temperature of the mullite phase after ball milling have dropped 400K.Although the crystal structure experiment of ball milling modification kaolin and alumag consumes 192 hours very long time costs, but, ball-milling technology is adopted to be applied in many new materials with mechanical force and chemical, how to improve the grinding efficiency of existing ball mill, the needs making it satisfied more mechanical force and chemical technique have very important realistic meaning, and multiple field adopts the research of mechanical force and chemical to make some progress.
As document is recorded, S.Franger etc., utilize physics and chemistry means to existing several method preparing LiFePO4, as high temperature solid-state method, coprecipitation, hydrothermal synthesis method and mechanochemical method, compare.Result shows, mechanochemical method can make the temperature of reactant and product, granularity, crystalline structure and uniform composition, thus make when synthesizing target product that required heating-up temperature reduces greatly, the heat time greatly reduces.Shi Zhicong etc. report and prepare LiFePO4 by carbon coated in conjunction with Mechanochemical Activation pretreatment, this method can make carbon matrix precursor more uniformly mix with reactant, and the reunion of product grain can also be stoped in sintering process, the granularity of product can be controlled better and improve the electrical conductivity of material, thus improving the performance of battery.
The metatitanic acid that Li Jing first etc. adopts ball milling sulfuric acid process ordinary-temp hydrolysis to obtain, owing to directly frequently applying shearing force, the adsorption water of the hydrated titanium dioxide particle after hydrolysis and ionization and hydroxyl is made to be subject to shear stress effect, dehydration and dehydroxylation can be realized sooner, more directly than heat energy utilization, prepare the nano titanium oxide that particle size is about 6.5nm.ViginieNivox utilizes mechanical force and chemical principle by Fe2O3 and V2O3 in planetary mills after grinding 12h, through 500 DEG C, sinter under 10-2.5Pa condition, can obtain the Fe2VO4 nanocrystal of high reaction activity, its crystallite dimension is less than its performance of 100nm close to the standby Fe2VO4 nanocrystal of chemical legal system.Jiang Jisen etc. are with Fe2O3 and ZnO powder for raw material, and under the effect of high-energy ball milling, room temperature (about 25 DEG C) synthesis zinc ferrite (ZnFe2O4) is nanocrystalline, and the nanocrystalline spinel structure with the distribution of non-eurymeric of gained is superparamagnetism.GaoZhe etc. utilize mechanical attrition method successfully to prepare the boron nano particle of dopamine modification, and its particle diameter is only 40nm.This nano particle can present fluorescence under specific condition, thus can be used for the particle that is positioned in cell medium.Meanwhile, the boron nano particle of dopamine modification does not show toxicity to mouse macrophage.
