Since the ion-exchange membrane electrolyzer adopts the liner ultrapure plastics, the erosion resistance to the electrolyte is enhanced, the heat-expansion and cold-contraction resistance of the ion-exchange membrane electrolyzer during the using process is enhanced, the service life is prolonged, and the stability of the process and the running of the equipment are ensured.
Description
Technical field
The utility model relates to a kind of ion-exchange membrane electrolyzer, particularly a kind of ion-exchange membrane electrolyzer that is used to prepare the electronic-grade Tetramethylammonium hydroxide.
Background technology
Tetramethylammonium hydroxide (Tetramethylammonium Hydroxide is called for short TMAH) is a kind of organic alkali with strong penetrating power.Since 20 beginnings of the century came out, TMAH had important purposes at aspects such as organic synthesis, catalyzer, tensio-active agent, clean-out systems.Technical grade TMAH is mainly used in reactions such as catalyzed polymerization, condensation, Ka Nichaluo as basic catalyst, as the polymerizing catalyst of silicon rubber production process, and preparation rubber antioxidant condensation catalyst etc.The TMAH of electronic-grade requires the single metal ion content less than 10ppb, do not retain later characteristics such as micro-electric conductivity impurity because of having strong penetrating power, volatile, use, being widely used in the production process of liquid crystal production and semi-conductor chip as developing solution, also is one of maximum electronic chemical product of consumption.
Ion-exchange membrane electrolyzer is in the widespread use of electrolysis industry.Ion-exchange membrane electrolyzer is because of intercepting by ionic membrane, and electrolysis production has the advantage of the low solution of metals content impurity, occupies main status in the high-purity and ultrapure chemical of electrolytic preparation.It is anode that Japan TAMA company adopts graphite, the titanium electrode that applies the platinum oxide compound and stainless steel and nickel in the U.S. Pat 4572769 of application in 1986, and fluorohydrocarbon is the electrolytic system of electrolytic film, but to electrolyzer without any description.
U.S. Pat 4572769; US 4634509; US 4892944 discloses the synthetic method of the raw material TMAC of electrolytic preparation TMAH; for the electrolyzer part; only mention the employing ion-exchange membrane electrolyzer; do not mention details such as cell construction and material, in the statement of patent protection not to the safeguard clause of electric groove material and structure etc.
In the domestic research report, Zhang Zhongmin etc., " electrolytic process prepares the research of Tetramethylammonium hydroxide ", " Jiangxi chemical industry ", 1996, (2): 11-14 delivers relevant research with ion-exchange membrane prepare Tetramethylammonium hydroxide, electrolyzer is not described and reports.Chinese patent application CN1312400 disclose ion-exchange membrane electrolysis prepare tetramethyl ammonium hydroxide method, electrolyzer do not appeared in the newspapers yet.
The ion-exchange membrane electrolyzer that uses both at home and abroad mainly is made up of anode, negative electrode, ion-exchange membrane, electrolyzer frame etc. at present, and every electrolyzer is made up of several unit grooves.The electrolyzer frame mainly adopts metal or common plastics to make, and therefore the problem that occurs is that electrolytic process generation heat makes the groove frame produce distortion, thereby produces poor sealing performance, production problems such as material from leakage.
Summary of the invention
The utility model discloses a kind of erosion resistance, the ultrapure plastics ion-exchange membrane electrolyzer of the liner of heat-resisting bloated shrinkage performance.
The ion-exchange membrane electrolyzer of the ultrapure plastics of a kind of liner comprises that by the hold-down gear fixed several unit grooves that have the groove frame form, described groove frame be metallic substance, groove frame and electrolytic solution contact part are lined with ultrapure plastic layer.
The utility model ion-exchange membrane electrolyzer is at the ultrapure plastics of groove frame liner, add and man-hour ultrapure plastics are cut into some by shape, the size of groove frame, with glue (as the Ai Laoda glue of Switzerland) that ultrapure plastic sheet and groove frame is bonding, for guaranteeing its bonding strength, can weld at the seam crossing of adjacent ultrapure plastic sheet or ultrapure plastic sheet edge, increase between the ultrapure plastic sheet and ultrapure plastic sheet and intermetallic strength of joint and adhesive power.
Because the groove frame is lined with ultrapure plastic layer, does not directly contact with electrolytic solution, so just reduced material requirement to groove frame metal part, general carbon steel or stainless steel etc. all can use.
Described ultrapure plastic layer is the ultrapure composite panel of plastic material of band glass fibre enhanced, content of glass fiber can adopt the scope of existing current techique, it is additive-free when being processed into sheet material that ultrapure plastics refer to the resin of plastics, thickness 1mm above (general 1～10 millimeter), process the resin of ultrapure composite panel of plastic material and can select polyphenylene ethyl diacid (PTA) for use, polytetrafluoroethylene (PTFE) and modified product thereof, or polypropylene (PP) etc.
General plastics all can add some additives in forming process, as inorganic enhancement component (lime carbonate, barium sulfate etc.), soak at liquid body, when especially corrosive liquid soaks, portions additive can dissolve, dissociate or split away off, cause defective in the plastics microtexture, corrosion resistance nature descends greatly, so the ultrapure plastic layer in the utility model adopts additive-free resin forming to form.
Ion-exchange membrane electrolyzer of the present utility model, the ultrapure plastics of employing liner have improved the erosion resistance to electrolytic solution, have improved heat-resisting bloated shrinkage performance in the ion-exchange membrane electrolyzer use, have prolonged work-ing life, have guaranteed the stability of Processes and apparatus operation.
Description of drawings
Fig. 1 is the groove frame synoptic diagram of ion-exchange membrane electrolyzer of the present utility model.
Embodiment
Referring to Fig. 1, the groove frame of the utility model ion-exchange membrane electrolyzer adopts metal frame 2, metal frame adopts stainless steel 304 materials, at metal frame 2 inwalls and each side, promptly the position that might contact with electrolytic solution is bonded with ultrapure plastic layer 3, and gas liquid outlet 1, liquid-inlet 4 and net sheet 5 all can adopt existing current techique to process among the figure.
Ultrapure plastic layer 3 is band glass fibre enhanced tetrafluoroethylene composition board, the machine-shaping of tetrafluoroethylene composition board do not use additive.Ultrapure plastic layer 3 thickness are 4mm.
Add and man-hour the tetrafluoroethylene composition board is cut into some by shape, the size of groove frame, Ai Laoda glue with Switzerland is bonding with tetrafluoroethylene sheet and groove frame predetermined position, for guaranteeing its bonding strength, seam crossing and tetrafluoroethylene sheet edge at adjacent tetrafluoroethylene sheet weld, and increase adhesive power.
After groove frame liner was carried out, dress upper net plate 5 was successively placed on anode unit and cathode electrode unit on the hold-down gear again in the groove frame, divide several stages slowly several unit grooves to be compressed, pressure-controlling waits about the interior water pressure testing 0.1MPa of electric groove about 10MPa, guarantees not have between each unit groove and leaks.
