Abstract
A kind of continuous preparation method's invention of heterogeneous ion-exchange membrane, the adhesives of ion exchange resin adopts LLDPE base alloy in the present invention, with the four-roll calender continuous film forming, presses net arrangement to press net, the continuous rolling finished product of takers-in continuously.The product flatness is good, the thickness deviation of film is less than ± 0.02mm, and raw material availability reaches more than 95%, production efficiency than batch process Senior Two doubly more than, the ion selectivity of film is greater than 90%, the chemical property and the chemical property of film are even.
Description
The invention relates to the continuous preparation method's of heterogeneous ion-exchange membrane invention.
Heterogeneous ion-exchange membrane is the functional separation film of present China output maximum, and it is compared with the homogeneous phase ionic membrane has that ion concentration is big, mechanical strength is high and characteristics such as practicality is good.Along with the expansion of range of application, product yield is brought in constant renewal in, and the international marketing amount was doubled in 5 years, and the home sale amount is turned over two times the same period.Present engineering of water treatment is electrodialysis and corollary equipment for example, quality and quantitative requirement to film are increasing, yet open among the clear 54-5888 present prior art spy, vistanex and powdery cationic ion-exchange resin is mixing with roller or extruder, then form membranoid substance.This method rises significantly for the resistivity that does not make film, and obtain transference number of ions height and mechanical strength heterogeneous ion-exchange membrane preferably, need handle film with the hot water more than 75 ℃, so that film produces the part fine fisssure, and then film being handled with surface-crosslinked polymer with ion-exchange group or the monomer of the fine fisssure of film part and film, whole technology is discontinuous carrying out.
The objective of the invention is for the continuous preparation method of a heterogeneous ion-exchange membrane is provided.Press net, the continuous rolling finished product of takers-in continuously with four-roll calender continuous film forming, pressure net arrangement in the present invention.The present invention has overcome the shortcoming of prior art, has improved flatness, utilization ratio of raw materials and the production efficiency of film by contrast.
The present invention presses net, the continuous rolling finished product of takers-in continuously with LLDPE base alloy (being also referred to as the low pressure low density polyethylene (LDPE)) and the blend of powdery ion exchange resin, four-roll calender continuous film forming, pressure net arrangement.So that provide a continuous preparation method of heterogeneous ion-exchange membrane.
LLDPE base alloy composition comprises 30～50% LLDPEs (LLDPE) in the present invention, 30～50% ethylene-vinyl acetate copolymers (EVA) and 20～40% polyisobutene (PIB).
The present invention's four-roll calender continuous film forming, this four-roll calender is converted by SY4F1120A.
Its roller diameter is 360mm, and roller length is 1120mm rotating speed 3～10m/min, 80～150 ℃ of operating temperature ranges.
The present invention presses net to adopt the instantaneous continuous pressure network process of high temperature, utilizes the pressure between the roller with the molten condition of membrane surface screen cloth to be pressed in the diaphragm, and pressure net temperature range is 130～180 ℃.
The present invention prepares heterogeneous ion-exchange membrane continuously, and package unit is in the synchronous working state, and takers-in, chill roll, screen cloth are led out roller, doubling roller and carrying roller and four-roll calender and pressed net arrangement is operation continuously synchronously.
Adopt heterogeneous ion-exchange membrane, the film flatness of continuity method preparation good, the thickness deviation of film width and length direction is less than ± 0.02mm, raw material availability reaches more than 95%, production efficiency than batch process Senior Two doubly more than, the ion selectivity of film is greater than 90%, and the chemical property and the chemical property of film are even.
Accompanying drawing is the continuous film releasing of different-phase ion symphysis and presses the net schematic flow sheet continuously.
The figure sequence number is 1,2,3,4 for four-roll calender, and 5,6,7,8 be chill roll, and 9,10 be screen cloth, and 11,12 lead out roller for screen cloth, and 13,14 is the pressure net arrangement, and 15,16 is doubling roller, and 17 is takers-in, and 18,19,20,21,22 is carrying roller.
Material running in the accompanying drawings is: constantly add the top of the roller 1 and the roller 2 of four-roll calender through the base-material that is rich in amberlite cosmetics of over-mastication, roll into satisfactory diaphragm through roller 1, roller 2, roller 3 and roller 4.Be used for two layers of screen cloth up and down that ionic membrane strengthens, respectively by screen cloth lead out roller 12 and 11 lead out the back introduce the top of ionic membrane and below.Two layers of screen cloth are pressed into screen cloth in the film through pressing net arrangement 13 and 14 up and down, through chill roll 5,6,7,8 coolings, after trimming device is cut edge continuously, batch product by takers-in 17 then.Product dispatches from the factory by size cutting, the packing of customer requirements after quality examination is qualified.Can better understand advantage of the present invention with reference to following example.
Example 1
With weight ratio is that (it consists of 30～50%LLDPE for 1: 4 to 1: 2 LLDPE base alloy, 30～50%EVA and 20～40%PIB) 5～15 minute makes film base in 120～160 ℃ of following blend with powdery ion exchange resin in the open type dual-roller mixing roll, the transport membrane base rolls into satisfactory diaphragm to the top of the roller 1 and the roller 2 of four-roll calender through roller 1, roller 2, roller 3 and roller 4.Here the operating temperature of four-roll calender is 80～150 ℃, continue allow diaphragm with lead out the upper strata screen cloth that roller 12 leads out and lead out lower floor's screen cloth that roller 11 leads out and send into the pressure net arrangement that roller 13 and roller 14 are formed simultaneously, under 130～180 ℃ of temperature conditions, be pressed into screen cloth in the film body continuously, then through chill roll 5,6,7,8 coolings, after trimming device is cut edge continuously, batch product by takers-in 17, product dispatches from the factory by size cutting, the packing of customer requirements after quality examination is qualified.Product quality sees Table 1.
