2Be stabilizing agent, it makes film possess lubrication in the thermoforming process, again anion exchange resin is played stabilization.
Antioxidant among the present invention is four pentaerythritol resins.It is the antiaging agent of olefin material, plays anti-oxidant price reduction effect.
Amberlite cosmetics among the present invention is that the strongly acidic styrene is a sample cationic ion-exchange resin powder 001 * 7, this resin-oatmeal is used to prepare cation-exchange membrane, or strong-basicity styrene series sample anion exchange resin powder 201 * 7, this resin is used to prepare anion-exchange membrane.The fineness of above-mentioned resin-oatmeal is 200～250 orders, helps improving the exchange capacity of film.
The preparation method of the polyethylene heterogeneous ion exchange membrane that packed-bed electrodialysis desalination device of the present invention is used, its step comprises:
A, with chlorosulfonated polyethylene, polyisobutene trivial refining in two roller machine earlier adds polyethylene from high pressure process, linear low density polyethylene then, the s-B-S copolymer, antioxidant is mixing in two roller machine, and melting temperature is 110～130 ℃, and mixing time is 8～10 minutes;
B, calcium stearate is added in the mixed material, mixing evenly after, add amberlite cosmetics, treat to mix fully the back discharging;
C, mixed material is put into two-roll calendar calendering pull out diaphragm, diaphragm thickness is 0.40 ± 0.03mm, and rolling temperature is 70～90 ℃;
D, above-mentioned diaphragm is embedded between the two-layer enhancing terylene screen cloth, being mixed with coincides originally enters hydraulic press hot pressing, and hot pressing temperature is 120～160 ℃, and hot pressing pressure is 0.4～0.6Mpa, and hot pressing time is 40～50 minutes.
Packed-bed electrodialysis desalination device is a filling ion-exchange resin between the anion-exchange membrane of electrodialysis fresh water compartment and cation-exchange membrane, under polarized state, makes hydrolytic dissociation, produces OH

+Near the enrichment OH ion, anion-exchange membrane
-Near the enrichment H ion, cation-exchange membrane
+Ion, OH
-Ion and H
+Ion is with cation in the exchanger resin such as Na
+With anion such as Cl
-Cement out, make ion exchange resin regeneration, protect the Shiqi ion-exchange capacity.Raw water is that (resistance of water is 10 to reverse osmosis water
6Ω), this raw water is removed Na through the ion exchange resin between the amberplex
+And Cl
-Plasma, the Na on the ion exchange resin
+And Cl
-By H
+And OH
-Ion exchange is come out to shift to the outer dense pool of amberplex and is discharged.Na in the raw water
+And Cl
-By after the ion exchange resin absorption, (resistance of water is 12～15 * 10 to generate ultra-pure water in the yin, yang ion
6Ω) discharge from the fresh water district.Ultra-pure water is widely used in electronics industry, power generation industries, medicine, biotechnology and laboratory water.
Compare with common electrodialysis membrane for water treatment, polyethylene heterogeneous ion exchange membrane of the present invention has the following advantages: one, the linear low density polyethylene of the present invention's adding, and the degree of cross linking of film is increased, compactness improves.Two, the chlorosulfonated polyethylene among the present invention makes film have acid resistance and non-oxidizability.Three, the s-B-S copolymer among the present invention not only increases the crosslinked of film
Degree, also part substitutes polyisobutene, has reduced production cost.
Packed-bed electrodialysis desalination device organically is combined into one electrodialysis and amberplex, make its function that possesses inner ion exchange resin automatic regeneration, thereby water quality is more stable.
When the packed-bed electrodialysis water inlet meets the requirements (reverse osmosis water is as water inlet), inner ion exchange resin can keep stable state, does not therefore need to carry out resin regeneration by the soda acid chemical reagent.
