Abstract
The invention discloses carbon nanotube dispersion equipment and belongs to the field of novel material dispersion. A process comprises the steps: (1) opening a charging plug and adding a carbon nanotube, and then adding a liquid state phase-changing medium through a working medium charging opening; (2) turning on a heating rod power supply switch and an ultrasonic vibrator switch for pre-treatment; and (3) when the temperature and pressure reach proper values, controlling a valve and a nozzle by controlling a valve control rod so as to achieve the purpose of dispersing the carbon nanotube by virtue of phase change of the medium. According to the process, external heating on a mixture in a pressure container in the original carbon nanotube dispersion equipment by using a heating belt is converted into internal heating by using a heating pipe and is assisted by ultrasonic vibration so as to quickly and uniformly heat a mixed solution of the carbon nanotube and the phase-changing medium, so that the energy is saved and the time is shortened.
Description
Art
The invention belongs to carbon nanotube dispersed field, particularly relate to a kind of carbon nanotube dispersed equipment.
Background technology
CNT is that graphite flake is curling according to certain helical angle, diameter is nano level tube-like materials.It has very large draw ratio, and heat exchange performance is alongst better, and the heat exchange performance of its vertical direction is lower, utilizes its anisotropy by suitable orientation, can obtain the composite with superior heat conductivility.But owing to having stronger Van der Waals force between CNT, add its very large draw ratio, cause it very easily to occur reunite thus reduce its performance in production and application process.And in use, often the aggregate of CNT fully will be disperseed just can reach desirable result of use.The dispersing apparatus of current CNT mainly uses sonic oscillation, ball mill etc. to realize the dispersion of CNT.By use the said equipment dispersing Nano carbon tubes have dispersion not thoroughly, longevity of service, have the shortcomings such as certain destructive and dispersion efficiency is low to CNT.
Chinese invention patent CN201310434933 provides a kind of carbon nanotube dispersed device based on draft flowing deformation, by cyclically-varying cavity volume volume, makes the mixture of CNT and epoxy resin constantly be compressed and loosen, and obtains the CNT disperseed.Though this kind of device can prepare the CNT of good dispersion, due to CNT in the course of work and epoxy resin mixing, be unfavorable for the application of CNT in other materials.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of CNT and phase change medium can effectively avoided and cause due to heat loss heating in heating process slowly and heat uneven equipment, advantageously in the dispersion of CNT.
To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is:
In pressure vessel inside, pressure jacket is installed, the heating rod of suitable dimension and power is set in pressure jacket, the heat that heating rod produces first is delivered to pressure jacket, CNT and phase change medium mixture inside is delivered to again by pressure jacket, be aided with ultrasonic oscillation, make mixture Fast Heating even.Then open valve, the mixture reaching proper temperature and pressure is sprayed by nozzle, utilize medium phase transformation to reach the object of dispersion.
The invention has the beneficial effects as follows, achieve CNT and the thermal loss less in heating process of phase change medium, save energy and time.
