Description
Technical field
The present invention relates to a kind of sulfur-bearing ether polyamine and its preparation method and application and the anti-oxidant Sulfide-containing Hindereds of a kind of chlorine-resistant point
From film and preparation method thereof, belong to polymeric material field.
Background technique
UF membrane science is the separation new science research to emerge rapidly after the 1960s.UF membrane is due to simultaneous
Have the function of separation, concentration, purifying and purification, but have efficiently, energy-saving and environmental protection and filter process is simple, the features such as easily controllable,
The fields such as food, medicine, biology, the energy, water process, bionical are widely used at present, production, the life of the mankind are produced
Tremendous influence, it has also become one of most important means in current separation science.Seperation film is the core in membrane separating process, and
Membrane material is then the development foundation of seperation film.Due to its good separating effect, energy conservation and environmental protection wide using pH range the advantages that, fragrance
Polyamide composite film (TFC membrane) is since by invention in fields such as sea water desalination, municipal wastewater processing and pure water preparations
It is used widely, also becomes one of the research hotspot of material supply section scholar.
Biological pollution is the main reason for causing film properties to reduce, and according to statistics, at least 28% film failure is the life by film
Caused by object pollution.In order to reduce fouling membrane, it usually needs a certain amount of bacteria remover, such as hypochlorous acid are added in pending water
Sodium, chloramines, phosgene etc. are because its is cheap, significant effect is used widely.However, aromatic polyamides composite membrane once and this
The chlorination that amido bond will occur for the contact of class bacteria remover replaces, and irreversible phenyl ring chlorination and hydrolysis then occurs, causes compound
Membrane flux reduces, rejection reduces, and then loses separating property.In general, composite membrane is about 200- to the tolerance of Active Chlorine
Therefore 1000ppm*h in practical operation, needs the water inlet to composite membrane to carry out dechlorination processing, chlorine element contains in guarantee water inlet
Amount is lower than 1ppm, after separation, then carries out chlorination processing to treated water and is contaminated again in running water system to avoid it.
On the one hand continuous dechlorination, chlorination lead to complex process, on the other hand also increase cost.Therefore, a kind of fenestra knot is prepared
Structure is easy to control, separating property is excellent and the oxidation resistant seperation film film of chlorine-resistant will be it is very necessary, have it is very important basis reason
By and practical application value.
According to the oxidation mechanism of aromatic polyamides, membrane science men propose the chlorine-resistant that following scheme improves aromatic polyamides
Performance.(1) using the secondary amine in tertiary amine substituted amide group, the surface grafting (2) of such as N-H key based on amido bond is in amido bond
N-H between introduce aliphatic bridge, (3) are to introduce strong electron-withdrawing group group on the connected phenyl ring of N-H, (4) introduce in polymerization process or
Surface coating inorganic sheath keeps apart aramid layer and Active Chlorine.Although these method of modifying more or less improve multiple
Close the chlorine-resistant property of film, but generally also along with the flux decline of film, rejection decline, complex process and cost is raised asks
Topic.
So far, few as the anti-oxidant Sulfide-containing Hindered separation membrane material of chlorine-resistant and its in high activity chlorine seperation film field
Application report.
