Description
Technical field
The present invention relates to CNT field of dispersions, a kind of CNT with electrostatic precipitator point is related specifically to
It is casually arranged with standby.
Background technology
CNT, is nano level tube-like materials that graphite flake is crimped according to certain helical angle, a diameter of.It has
Very big draw ratio, heat exchange performance alongst is very high, and the heat exchange performance of its relative vertical direction compared with
Low, by being suitably orientated, CNT can synthesize the heat conducting material of high anisotropy.Because CNT itself is stronger
Van der Waals force and very big draw ratio, cause it easily to reunite in process of production.And when in use, often
Into single CNT or removal preferable using effect is can be only achieved by the aggregate of CNT is fully dispersed.At present
The dispersing apparatus of CNT mainly realizes the scattered of CNT using sonic oscillation, ball mill etc..Set by using above-mentioned
Standby dispersing Nano carbon tubes have scattered not thorough, longevity of service, have certain destructive and dispersion efficiency low to CNT
Shortcoming.
Chinese invention patent CN201310434933 provides a kind of CNT dispersal device based on draft flowing deformation, leads to
Cyclically-varying cavity volume volume is crossed, the mixture of CNT and epoxy resin is constantly compressed and is loosened, obtains scattered
CNT.Though this kind of device can prepare the CNT of good dispersion, due to CNT and epoxy in the course of work
Mixed with resin, is unfavorable for application of the CNT in other materials.
The content of the invention
For the scattered not thorough, longevity of service of prior art, there is certain destructive and dispersion efficiency low to CNT
Deng deficiency, the invention provides a kind of CNT dispersing apparatus with electrostatic precipitator, the equipment is by CNT gas
Phase dispersal device, electrostatic precipitator, reception device and ventilation unit etc. are constituted, wherein the main composition portion of electrostatic precipitator
Dividing includes negative ion generating device, positive plate, negative plate etc..
To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is：
The mixing of single-root carbon nano-tube, CNT aggregate and phase change material that CNT gas phase dispersion device is produced
Component, electrostatic precipitator is led into via air-flow.CNT aggregate in air-flow and it is scattered after single carbon nanometer
Pipe can carry negative electrical charge in the presence of negative ion generating device, in the uniform electric field that they are formed by battery lead plate, carry
The aggregate of a large amount of negative electrical charges can be gathered in positive plate in the presence of electric field force, at the same time, carry relatively small amount negative electrical charge
CNT in the presence of small electric field force can by uniform electric field, and be collected device seizure, so as to reach separation of carbon
The purpose of nanotube agglomeration body.
The beneficial effects of the invention are as follows the CNT dispersing apparatus of the present invention with electrostatic precipitator can
With the CNT aggregate in separating carbon nano-tube blending ingredients, equipment is simple, and safe and reliable, effect is good.
