Description
Technical field
The present invention relates to a kind of preparation field of particle, be specifically related to a kind of nano particle preparation system and preparation method thereof.
Background technology
Nano particle has huge market prospects because it has huge specific area, especially in industries such as automobile making, pharmacy, but nano particle due to its particularity, production cost is compared higher with conventional particles.
The method of manufacturing nano particle particle mainly can be divided into upwards method (bottom up) and to laxative remedy (top down).Most typical is grinding method to laxative remedy, as the term suggests exactly bulky grain is milled in solution to nano particle.The method power consumption is very high, and is milled into the non-constant of granule stability of Nano grade, need to add corresponding stabilizing agent, and the nano particle purity of simultaneously producing by the method is very low, conventionally contains milling container and the composition of the ball of milling.Conventionally the method is only applicable to the industry that some do not contact and particle purity is not required with human body.
Upwards method can be divided into liquid phase method and vapor phase method, and the two method is to manufacture nano particle by single atom or molecule.The method of liquid phase method generation nano particle is generally fairly simple, and the relative concentration that produces nano particle is higher, but the nano particle of producing by liquid phase method needs a lot of subsequent processes, such as Separation of Solid and Liquid, cleans, and is dried calcining etc.Its shortcoming is that production process is uncontrollable, once reaction starts, its manufacturing parameter just cannot change, and the nano particle size of manufacturing by the method is in addition uncontrollable.In addition, the nano particle of manufacturing by liquid phase method, its purity is not high, is mainly the restriction that is subject to its mode of production.The particle obtaining by liquid phase method more or less contains the not material of complete reaction.In addition, the nano particle of manufacturing by the method mostly is polymer, and it has limited further processing and use to nano particle, and liquid phase method is discrete method, so the method has limited production output.
Nano particle can also be manufactured by vapor phase method.The nano particle producing by vapor phase method does not need to carry out follow-up processing, and by particle collector, collecting just can be stand-by, and the concentrations of nanoparticles of producing by the method is very high, almost can reach 100%.The feature of another one vapor phase method is exactly that production process can be controlled, and can change as required response parameter, thereby obtains the particle properties of expectation, such as manufacturing nanometer spherical particle etc.The method can directly be attached to certain carrier surface the nano particle of producing and form a nano-deposit.Meanwhile, vapor phase method is a continuous method, can continual production nano particle, and vapor phase method can expand equipment as requested easily, improves output.Vapor phase method can be divided into gas and transform particle method, and liquid transition particle method and solid convert particle method to.Vapor phase method is produced the process of nano particle for for by raw material gasification, then by physics or chemistry route, manufactures nano particle.Detailed process is, first forms a granular core, then according to reaction condition, by continue condensation or surface chemistry side should or collision and the polymerization of particle form nano particle.But at present, the vapor phase method adopting on existing market is produced the comparison in equipment complexity of nano particle, and cost is relatively high, and the cost of collecting nano particle is higher.
