Technical field
This utility model belongs to water process membrance separation field.It particularly relates to a kind of use for laboratory membrane for water treatment interface polymerization reaction device.
Background technology
The most most widely used, also be the maximally effective method preparing membrane for water treatment be Preparation of Thin Film Composite Membrane by Interfacial Polymerization Method.The method is to be combined one layer of superthin layer with nanoscale aperture on basement membrane, and superthin layer, as stratum disjunctum, plays the effect retaining separation.First basement membrane is immersed in the aqueous solution containing active monomer or prepolymer, abundant moistening surface, then this film is taken out and get rid of excess solution, be subsequently dipped in the organic phase solution containing another kind of active monomer.Owing to both solvents are immiscible, therefore its reaction can only be carried out on the interface of two kinds of solution phases, and the speed of monomer reactivity height reaction quickly, the most just can form the composite bed of densification on porous supporting body.Thus cause the rejection of composite membrane and selectivity all to greatly improve.
But there is no at present the interface polymerization reaction device of molding on the market, major part is all that laboratory passes through simple and crude device (such as plastic bottle, rubber ring etc.) self-control and forms, and device is simple, and the easy seepage of reaction liquid exists the biggest potential safety hazard.And Preparation of Thin Film Composite Membrane by Interfacial Polymerization Method is it is generally required to the membrane material of good hydrophilic property, the membrane material poor according to hydrophilic carries out interfacial polymerization, and the composite bed formed will be insecure with basement membrane laminating, less stable；Even if using hydrophilic membrane material to carry out interfacial polymerization, composite bed obscission can be there is in major part, this is because the active monomer in aqueous solution is difficult to enter inside membrane surface space in impregnation process, and membrane surface hole exists the gas of residual, the composite bed obtained after causing interface polymerization reaction is combined insecure with basement membrane.
Summary of the invention
Technical problem to be solved in the utility model is: for the deficiencies in the prior art, it is provided that a kind of good airproof performance, can realize gas pressurized and can be hydrophobic film a kind of use for laboratory membrane for water treatment interface polymerization reaction device of carrying out interfacial polymerization.
The technical scheme that the above-mentioned technical problem of this utility model solution is used is: described a kind of use for laboratory membrane for water treatment interface polymerization reaction device is at the bottom of by cup, upper circular gasket, membrane for water treatment, lower circular gasket, circular ferrum clip, cup is constituted, inlet and gas pressurized mouth are arranged at described cup top, described gas pressurized mouth connection high-pressure air feed device, it is with circular arc projection outside top periphery at the bottom of described cup and described bottom of cup, waled by described circular ferrum clip with described cup at the bottom of described cup, screwing screw is had on described circular ferrum clip, described upper circular gasket and lower circular gasket is placed between at the bottom of described cup and described cup, described membrane for water treatment is placed between circular gasket and lower circular gasket.
Compared with prior art, the utility model has the advantage of: a kind of use for laboratory membrane for water treatment interface polymerization reaction device volume is small and exquisite, and dismounting is simple, good airproof performance；Gas pressurized mouth can connect high-pressure air feed device aqueous solution in reaction unit and impose physics high pressure, get rid of the gas of residual in membrane surface hole, active monomer in aqueous solution is easier to enter in the middle of the tiny hole of membrane surface, make that composite bed that interfacial polymerization obtains and basement membrane fit more firmly, more complete；Hydrophobic film can be embodied as by external physical high pressure and carry out interfacial polymerization；Gas pressurized mouth can connect the high-pressure air feed device of gas with various (such as carbon dioxide, nitrogen etc.), can probe into the impact of the composite membrane that interfacial polymerization is formed again after different types of gas-pressurized basement membrane on infiltrating in aqueous pressurizes；The solution pressurized treatments in different pressures downhill reaction device can be realized, the gas-pressurized of different pressures can be probed on the impact of the composite membrane that interfacial polymerization is formed again after infiltration basement membrane pressurization in aqueous.
