Abstract
The invention relates to a preparation device of nano composite material, which is composed of a gasification apparatus, a gas phase chamber, a gas passing pipeline, a fan-type nozzle, a nano material transporting apparatus, a finely atomizing spray nozzle, a passing channel, a ball valve, a composite reaction device, a reaction chamber, a receiving and recycling apparatus, a main receiving apparatus and a desublimation generator. The nano material flows from top to bottom through the passing channel. A solid-phase or a liquid-phase desublimatable work medium is evaporated into vapor through the gasification apparatus and then is mixed with the nano material in the reaction chamber. The nano material is subjected to a composite reaction and then is fed into the main receiving apparatus, and then is rapidly frozen under a low temperature to be desublimated into a solid-phase nano composite material. The preparation device can overcome a defect that when the nano composite material is prepared under liquid-phase mixing, a stirring process may cause secondary agglomeration of the nano composite material without addition of a surfactant or a dispersion agent which causes pollution on the nano composite material. The preparation device is simple in device, is low in use and maintenance cost and is safe and reliable.
Description
Technical field
The present invention relates to a kind of preparation facilities of composite, be related specifically to a kind of preparation facilities of nano composite material.
Background technology
Nano composite material is for continuous phase with matrixes such as resin, rubber, pottery and metals, with modifier such as the metal of nano-scale, semiconductor, rigid particles and other inorganic particulates, fiber, CNTs for decentralized photo, by suitable preparation method, modifier uniformity is scattered in matrix material, form the compound system containing nano-sized materials, this system material is referred to as nano composite material.
Nano material is otherwise known as superfines or ultrafine dust usually, and be a kind of physical form being in the transitional region that macro object and atom place have a common boundary, its structure has uniqueness, is namely different from single atom, is different from again body block of material.This special structure makes it have the features such as quantum size effect, bulk effect, skin effect, has a series of new chemistry and physical characteristic, especially in optical, electrical, catalysis etc., has very important using value.
The granularity of nano-powder is trickle, specific area is large, surface energy is high, surface atom number increases and Atomic coordinate is not enough etc., make these surface atoms have very high activity, extremely unstable, be easy to reunite the larger-size aggregate formed with some linkage interfaces.Such agglomeration determined by its surface characteristic.When material particle size reaches Nano grade, its surface atom proportion reduces with particle diameter and increases sharply, and surface atom is very different with the field of force suffered by the atom being in crystals: the stressed symmetry of interior atoms, valence link are saturated; Outside atom is then contrary.The aggregation procedure of these fine particles is exactly the continuous formation of adhesion between particle in fact, the process that system gross energy constantly reduces.While nanometer technology is widely used in every field, the reunion scattering problem of nano particle seriously hinders the extensive use of nano material, becomes a very stubborn problem.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of preparation facilities of nano composite material, this device is made up of gasification installation, phase chamber, gas operation pipeline, fan nozzle, nano material conveying device, finer atomization nozzle, operation passage, ball valve, complex reaction device, reaction chamber, reception retracting device, main receiver and generator of sublimating.
The technical solution used in the present invention is: during use, and nano material is via nano material conveying device under the air-flow that fan nozzle sprays drives, and run from top to bottom along operation passage, fan nozzle is symmetrical, and ejection airflow function is in whole service passage.
Become steam as the solid phase of matrix material or liquid phase working medium of can sublimating through gasification installation, in phase chamber, steam runs pipeline through gas and enters reaction chamber.Gas runs pipeline one end and connects phase chamber, and the other end is furnished with finer atomization nozzle, and is furnished with and controls solid phase or liquid phase and can to sublimate the ball valve of working medium flow and flow velocity.Side and the horizontal plane of gas operation pipeline connection finer atomization nozzle form an angle, symmetrical.In reaction chamber, nano material and solid phase or liquid phase working medium of can sublimating mixes, and enters the main receiver receiving retracting device after recombination reaction.
Main receiver directly contacts with generator of sublimating, and keeps comparatively large contact surface to amass.Make main receiver maintain mixed working fluid by the generator that controls to sublimate to sublimate required temperature range, composite is Quick freezing at low temperatures, sublimates as solid state.By controlling concentration and the transporting velocity of nano material, the object of quantitatively preparation nano composite material can be reached.
The invention has the beneficial effects as follows, overcome liquid phase state when being mixed with nano composite material, whipping process causes the shortcoming of nano material secondary agglomeration, does not need to add the surfactant or dispersant that cause nano material to pollute.Equipment is simple simultaneously, and use and maintenance is with low cost, safe and reliable.
