Description
Technical field：
The present invention relates to a kind of preparation method of carbon molecular sieve membrance, more particularly to a kind of waste and old aromatic polyamide reverse osmosis membrane
The method for preparing carbon molecular sieve membrance, belongs to new material technology field.
Background technology：
In recent years, osmosis filtration technology because its have normal temperature, without phase transformation, energy consumption is low, floor space is small, non-environmental-pollution, suitable
With water quality it is wide the advantages that, since the advent of the world just enjoys industry to favor, and quick development has been obtained, particularly in recent years in water resource
Famine, water pollution, environmental pollution are serious, sewage disposal, purification of water quality etc. there is an urgent need to and government policy support situation
Under, reverse osmosis technology has obtained high speed development, is widely used in boiler feedwater, industrial pure water, desalinization, municipal water supply
With sewage treatment area, also obtained in multiple industrial trades such as oil, electric power, metallurgy, chemical industry, electronics, pharmacy, food fully
Development, turns into important energy-efficient Engineering operation unit, realizes the important component of the strategy of sustainable development.
The reverse-osmosis membrane element that the whole world produces every year has several hundred million, and the Chinese reverse osmosis membrane market demand is wide, rough estimates, disappears
The amount of receiving accounts for the whole world 10%, and is rising year by year, according to the insiders analysis prediction, and China's film market demand will be with annual 20% or so
Speed increase.But reverse osmosis membrane, in separation process, easily contaminated or mechanical damage, causes its clearance and aquifer yield
Significantly decline, lead to not efficiency of bringing into normal play, its service life is usually 2-3 or so, belongs to easily-consumed products.Therefore,
The country there are about millions of membrane components and gone out of use because of hydraulic performance decline every year, and going from strength to strength with counter-infiltration market, this
Data are constantly being refreshed.These discarded reverse osmosis membranes are because its material can hardly be degraded under field conditions (factors), if place
It is improper to put, and not only pollutes environment and wastes resource.How to dispose the waste and old reverse osmosis membrane of this substantial amounts turns into industry
A great problem.
At present, there are two kinds for discarding the common processing mode of reverse osmosis membrane, first, as solid waste refuse disposal, this side
Method not only increases environmental pressure, adds offal treatment cost, while waste resource；Second, fraction is made profits again
With also having many unit or individuals for receiving and selling second-hand film on the market at present, it is notable that regeneration membrane industry often goes out
New, shoddy dirty pool now is rushed with old, and the reverse osmosis membrane service life after regeneration is short, must finally be used as solid
Useless refuse disposal, the shortcomings that both processing methods are all present clearly.Waste and old aromatic polyamide reverse osmosis membrane, due to residual
Charcoal amount is high, is the excellent presoma for preparing carbon molecular sieve, realizes the resource reutilization system of waste and old aromatic polyamide reverse osmosis membrane
Standby carbon molecular sieve, not only reduces the quantity of waste and old reverse osmosis membrane, reduces the processing cost of waste and old reverse osmosis membrane, be that one kind has
The processing mode of effect, while policy requirements of the country on changing rejected material to useful resource are also complied with, therefore, discard the outlet of reverse osmosis membrane
Key is in resource reutilization.
At present, the production of carbon molecular sieve membrance mostly prepares precursor film using solvent method, and this method is required for the solvent of costliness
Raw material is done, polymeric membrane is prepared come evaporation solvent by pyroprocess, this method all right and wrong in terms of resource or the energy
Often waste.Inventor is prepared for receiving the carbon molecular sieve of microchannel using waste and old aromatic polyamide reverse osmosis membrane first
Film.
The content of the invention：
A kind of low cost, simple production process are provided, are easy to it is an object of the invention to overcome the shortcomings of above-mentioned prior art
The industrialized method for preparing carbon molecular sieve membrance with waste and old aromatic polyamide reverse osmosis membrane, its carbon molecular sieve membrance prepared machinery
Intensity is high, pore structure is flourishing, separating property is good.
The purpose of the present invention can be reached by following measure：
(1) cleaning and preservation of waste and old aromatic polyamide reverse osmosis membrane：By waste and old aromatic polyamide reverse osmosis membrane using super
Method for acoustic cleans, and washes away impurity such as incrustation scale, microorganism etc. of its surface adhesion, then that washed waste and old aromatic polyamide is anti-
Permeable membrane dries in the shade at normal temperatures, is placed in preserving at least 24 hours between two pieces of graphite cakes, flattens.
(2) pore size control agent is put into blender with adhesive under normal temperature to be well mixed, adhesive then requires stronger
Cohesive force and a certain degree of plasticity, the preferably macromolecule such as epoxide-resin glue, polyester resin glue, polysilane base resin glue
For polymer as adhesive, the addition of adhesive is preferably the 85%~99% of mixture gross mass, and pore size control agent is preferably
Zeolite, nano silicon, nano titanium oxide, one or more kinds of mixtures of magnetic iron oxide, by adhesive and
The mixture uniform ground of pore size control agent is coated in from a piece of waste and old aromatic polyamide reverse osmosis membrane taken out between graphite cake
Surface, it is viscous in the above from another waste and old aromatic polyamide reverse osmosis membrane is taken out between graphite cake；Again by two panels bonding
Waste and old aromatic polyamide reverse osmosis membrane is put into seamless molding machine, and control briquetting pressure makes between 0.5~1.0 Mpa
The waste and old aromatic polyamide reverse osmosis membrane of two panels holds tightly together, and it is small to allow it to dry 10 at 60 DEG C in vacuum drying chamber
When.
（3）Bonding, dried waste and old aromatic polyamide reverse osmosis membrane are put into retort, in inert gas shielding
Under charing process is carried out with certain heating rate after just prepare required carbon molecular sieve membrance.Preferably, wherein inert gas
From the one of which of nitrogen, argon gas, heating rate general control in 1~5 DEG C/min, charing final temperature is ordinarily selected to 400~
900 DEG C, and 60~240min of constant temperature at this temperature.
The present invention can produce following good effect compared with the prior art：Applicant is by largely investigating and experiment is ground
Study carefully, the carbon molecular sieve membrance with high value is prepared using waste and old aromatic polyamide reverse osmosis membrane, it has the following advantages that：
(1) carbon molecular sieve membrance that waste and old aromatic polyamide reverse osmosis membrane prepared for persursor material not only production cost is used
It is low, waste and old aromatic polyamide reverse osmosis membrane can be effectively utilized, but also there is higher porosity and flux, pore structure is equal
Even, high mechanical strength.
(2) average pore size of carbon molecular sieve membrance and pore-size distribution are easily controllable.The present invention by change pore size control agent and
Species, addition and the carbonization condition of adhesive can prepare the carbon molecular sieve membrance for different separation requirements.
(3) the carbon molecular sieve membrane porosity prepared is high, and mechanical strength is big, and the smooth zero defect in surface.
