Description
Technical field
The present invention relates to the devices that a kind of microwave heating prepares oxidization fiber, belong to microwave heating technique technical field.
Background technology
Precursor pre-oxidation process carries out between 180~280 DEG C, presently mainly using traditional heatings such as Muffle furnaces
Mode is realized.Traditional heating mode is from outward appearance to inner essence heated by radiation, convection current and conduction.Preoxidation process is double diffusion
Course, oxygen are from outward appearance to inner essence spread to fibrous inside, and internal non-carbon element micro-molecular gas product is to external diffusion.With pre-oxidation
The progress of reaction, the strand of fiber sheath have been initially formed fine and close trapezium structure, oxygen are hindered to be spread to core, makes fiber shape
Core annellated, the degree of cross linking is relatively low.Pre-oxidation is progressively carried out from fibrous external to core, the cyclisation and friendship of macromolecular chain
Connection effect makes oxidization fiber cortex fibril be initially formed fine and close netted trapezium structure, hinders the further diffusion of oxygen, occurs
The oxidation of oxidization fiber cortex is fully or even excessive, and core pre-oxidizes deficiency, thus forms skin-core structure.Traditional heating pre-oxidizes
When carbon fiber preparation process in take longest step, easily there is " core-skin " structure, and carbonisation can be genetic to so that is difficult
To obtain high performance carbon fiber.
Microwave heating has the advantages that following three:First, homogeneous heating.Electric furnace process heating is to pass to object by heat transfer
Inside, be easy to cause the half-cooked phenomenon of " outer burnt in not yet done ".The characteristics of microwave heating is maximum is that heat is in heating object
What inside generated, heat source comes from interior of articles, homogeneous heating.Mainly since electromagnetic wave has substance very strong penetration,
Penetration depth belongs to the same order of magnitude with electromagnetic wave free space wavelength, and the diameter of fiber is just in the range of this.So
Electromagnetism wave energy snap realizes homogeneous heating in the table of fiber whole cross section.Secondly, speed is fast.General heating means
It is the environment heated around heating object, heats object by the radiation of heat or the convection current of heating air.This heating
Mode efficiency is low, the time is long.Microwave is electromagnetic wave of the frequency range from 300MHz to 300GHz.Electromagnetic field is to the work of dielectric
With being that the polarization of substance causes object to generate heat the hysteresis effect of electric field.Electromagnetic field is electromagnetic induction to the effect of conducting medium,
Under the action of electromagnetic induction, fibrous inside will generate vortex, since fiber has certain resistance, so being led when flowing through
Heat is converted into during body fiber.Their common feature is the capacity of heat transmission that heating effect is not only restricted to substance, is solely dependent upon
The electrical property of substance and the parameter of additional electromagnetic field.Since the path of heat transfer is reduced, compared with conventional heating, microwave heating is
More rapidly with energy saving heating means.Again, Instantaneous Control.General heating means, heating or change furnace temperature are, it is necessary to the time
It is long.Microwave heating can realize the adjustment to microwave power in a few seconds, you can run well, and adjust microwave output work
Rate, material heating state immediately inertialess with change, realize heating immediately and adjust immediately, convenient for automation and serialization
Production.Therefore, PAN fiber preoxidation process can effectively avoid the deficiency of electric furnace process heating using microwave heating.
Since the dielectric constant of precursor is low, and fibre diameter is meticulous, it is difficult to efficient absorption microwave, so microwave energy utilizes
Rate is too low, and fiber radial structure is difficult to Effective Regulation.There are following for precursor pre-oxidation for current microwave heating equipment
Shortcoming:First, energy expenditure is big, can not reuse;2nd, energy can not dilute scattered, cause material uneven heating even;3rd, set
Standby closing can not carry out interrupted transmission heating to material.It is necessary that a kind of new-type add is provided in order to overcome these shortcomings
Thermal, and heating equipment is improved, realize the deposit of thermal energy, the dilution to energy changes heat-supplying mode and control
The mode of heating of precursor.
The content of the invention
For the above-mentioned prior art there are the problem of and deficiency, the present invention dress that a kind of microwave heating prepares oxidization fiber is provided
It puts.The device changes oxidization fiber mode of heating, promotes the efficiency of heating surface and capacity usage ratio, the present invention is by the following technical programs
It realizes.
A kind of microwave heating prepares the device of oxidization fiber, and including micro-wave oven, support tube and microwave absorbing coating, microwave oven internal is set
There is horizontal support tube, carrier pipe internal surface spraying microwave absorbing coating, support tube material is mullite or corundum not absorbing material, is inhaled
Ripple coating is ferrite or silicon carbide absorbing material.
Further include the first protective cover, asbestos, filament mouth, first axis of rolling, second axis of rolling, into silk mouth and second protect
Cover, the carrier tube outer surface are equipped with asbestos, and support tube is prevented with being respectively equipped with the second protective cover and first on micro-wave oven contact surface
Shield, the second protective cover and the first protective cover centre position are respectively equipped with into silk mouth and filament mouth, and precursor into silk mouth by passing through
Support tube comes out from filament mouth, and precursor, which is located at into silk mouth one end, connects second axis of rolling, positioned at the first rolling of filament mouth one end connection
Moving axis.
Thermocouple is further included, the thermocouple is inserted at the top of micro-wave oven inside support tube.
Second axis of rolling and the equal external connection power device of first axis of rolling.
The operation principle that the microwave heating prepares the device of oxidization fiber is:
Precursor be located at into silk mouth one end connect second axis of rolling, positioned at filament mouth one end connect first axis of rolling, precursor by into
Silk mouth comes out through support tube from filament mouth, under the microwave pre-oxidation effect of the present apparatus, constantly has precursor to enter support tube
Middle progress microwave pre-oxidation.
The beneficial effects of the invention are as follows:The method of the present invention is novel, clear in structure.Since absorbing material does not have very microwave
Strong permeability can make the energy that microwave discharges more uniform;Microwave absorbing coating can dilute microwave so that material inhales ripple more
Stablize;Support tube is wrapped up by asbestos, the energy of microwave release can be stored;By above-mentioned processing, oxidization fiber " core-skin " is eliminated
Structure, it is radially more uniform, volume density is improved, is laid the foundation to obtain high-performance carbon fibre.
