Abstract
This invention relates to heterophase ions exchange film with water process function and bacterial inhibition function, which can be used in electrodialysis assembly and ion tree resin matching and for sea water and salt water desalt and to process boiler water, distilled water and purified water with bacterial inhibition function.
Description
Technical field
The present invention relates to a kind of material for water treatment preparation field, specifically a kind of have treatment function and have antibiotic heterogeneous ion-exchange membrane of bacteria resistance function and preparation method thereof again.
Background technology
Water is a kind of important natural resource, for satisfying an adult's physiological requirements, approximately need 2 liters water every day, for keeping cleaning, cooking food, family's heating and air conditioning etc., to consume 2850 premium on currency for each person every day, and the big statistics that is difficult to especially of industrial water consumption, moreover also have a large amount of farmlands to need to irrigate.
Though enough water is arranged in the ocean, can cover the whole earth, and its degree of depth can reach 2 miles.But the needed most of water of people, majority can only be satisfied by fresh water, and tellurian pure water is reducing year by year, many areas, the world all exist the serious problems of fresh water deficiency.For this reason, developed country all regards the ocean as water supply potential in the source.Method for desalting seawater has multiple, and wherein a kind of is to adopt heterogeneous ion-exchange membrane to carry out desalination, makes seawater and bitter, obtains desalination and handle in the device (claiming electrodialysis plant again) that heterogeneous ion-exchange membrane is formed.
The different-phase ion film has been widely used in seawater, brackish water desalination at present, preparation boiler feed water, distilled water, pure water etc., even can processing section harmful ion and radioactive element.But the different-phase ion film is in water treatment procedure, and long period of soaking can be made the surface form one deck mucous membrane, thereby greatly reduce the ability of its desalination by germ contamination in the water in water, and whole water treatment facilities disposal ability is constantly descended.Therefore, in the composition of heterogeneous ion-exchange membrane, add a kind of having no side effect, have the inorganic antiseptic of long-acting, broad-spectrum bacteria resistance function again, just can make face can not grow bacterium.
Summary of the invention
Purpose of the present invention, seek a kind of inorganic bacteriostatic agent that has no side effect exactly, when preparing, heterogeneous ion-exchange membrane adds then, make the heterogeneous ion-exchange membrane of generation have bacteria resistance function, make face one deck mucous membrane no longer occur, thereby improve the salt rejection rate of film and select transmitance, prolong the service life of film.
The specific embodiment
The present invention implements by following method
Amberplex divides styrene sulfonic acid type cation-exchange membrane to claim cation-exchange membrane again, and styrene quaternary amine type anion-exchange membrane claims anion-exchange membrane again.The two pairing is used during use, is assembled into electric dialyzator, carries out desalination and ion and purify under two electrode current effects.The manufacturing process of these two kinds of films is the same, the ion exchange resin difference that only is to use.Cation-exchange membrane uses styrene sulfonic acid type cationic ion-exchange resin, and anion-exchange membrane adopts styrene quaternary amine type anion exchange resin.For improving its water treatment capacity, the ion exchange resin that must use the making ionic membrane is earlier pulverized before use, and its fineness is generally about 200 orders.In order to make its film forming must add other component, wherein have as the polyethylene of binding agent and the calcium stearate of polyisobutene and lubricate, reached the Nano Silver inorganic antiseptic of bacteriostasis.
Its part (weight ratio):
The polyvinyl resin high-pressure process, melt index 1.4-1.6 16-22
Polyisobutene molecular weight 200,000 above 4-6
Ion exchange resin (about powder 200 orders) 65-73
The concavo-convex excellent Nano Silver of bacteriostatic agent is less than 1000 order 3-5
Calcium stearate technical grade 1-2
The preparation method
At first the ion exchange resin that film is used is dried down at 60-80 ℃, the ion exchange resin of drying is crushed to about 200 orders packed for standby use.
Implement formula examples (weight ratio):
Polyvinyl resin described in the prescription is the hp-ldpe that high-pressure process is polymerized, and melt index is 1.4-1.6.
Polyisobutene described in the prescription, energy and polyvinyl resin play the effect of glue connection, require its molecular weight more than 200,000, to improve the ion-exchange film strength.
Ion exchange resin powder in the prescription is meant styrene sulfonic acid type cationic ion-exchange resin, or styrene quaternary amine type anion exchange resin, they at the powder fineness after the pulverizing about 200 orders.
Nano Silver described in the prescription is concavo-convex excellent Nano Silver, or concavo-convex excellent Nano Silver, zinc, and fineness is less than 1000 orders, and purpose makes film have bacteria resistance function.
Calcium stearate described in the prescription is a technical grade, first class product.
Implementing process:
The first step, elder generation 60-80 ℃ of oven dry down, are crushed to the film spent ion exchange resin about 200 orders then, and it is stand-by that same again bacteriostatic agent (Nano Silver) mixes in proportion the back.
Second step, refining glue are adjusted the roll spacing of rubber mixing machine roller earlier, make roll gap at 1-2mm, and the roller temperature rise is to 110-130 ℃, and rubber mixing machine roller temperature height is decided on the polyvinyl resin melt index.Add earlier polyvinyl resin in proportion, add the polyisobutene resin after the plasticizing evenly again and carry out mechanical grafting enhancing.
The 3rd goes on foot, first step ion-exchange resin powder and bacteriostatic agent powder mixture adding roller is moulded, and until even dispersion, along with mixed powder adds, the rubber mixing machine roll spacing is progressively amplified, and last roll spacing is amplified to 4-6m/m.
The 4th step, pulling-on piece, pulling-on piece machine roller temperature is 70-100 ℃, pulls out tablet from rubber mixing machine, enters pulling-on piece machine roll-in 1-2 road, is pressed into the 2-3m/m slice, thin piece, and then carries out pulling-on piece, last slice, thin piece is controlled at about 0.4-0.45m/m.The pulling-on piece machine can be two roller machines, preferably adopts three-roller, because three-roller makes material thickness even easily.
The 5th step, hot pressing strengthen, and for improving film strength, must strengthen reinforcing with screen cloth, and reinforcing is to carry out in hot press, and high yield preferably adopts multidaylight press.Preparation technology is: will pull out slice, thin piece earlier and be embedded between two nylon net cloths or the terylene screen cloth, and be placed among two corrosion resistant plates again, and put into hot press hot pressing, hot pressing temperature is 140-160 ℃, and pressure is 40-80kg/cm
2, the press time is 40-60 minute, is cooled to 40 ℃ with bottom discharge, promptly gets the antibacterial heterogeneous ion-exchange membrane that strengthens after the reinforcing.The salt rejection rate of this antibacterial heterogeneous ion-exchange membrane, select index such as transmitance and common heterogeneous ion-exchange membrane roughly the same, because the long bacterium in film surface can make the life-span that is to use of film improve more than 50% than common heterogeneous ion-exchange membrane.
