Chii chinonzi polymer?
Polymersmakomboni akagadzirwa nemamorekuru akabatanidzwa pamwechete mumaketani.Aya maketani anowanzo kureba uye anogona kudzokororwa kuti awedzere hukuru hwechimiro chemolecular.Mamorekuru ega ega muketani anonzi monomers, uye iyo ketani chimiro chinogona kugadzirwa nemaoko kana kugadziridzwa kuti uwane chaiwo zvivakwa uye zvivakwa.
Kusikwa kwevhu rekuita-mazhinji-chinangwa iko kushandiswa kwemamodified polymer molecular structures.Muchinyorwa chino, zvisinei, isu tichatarisa pamapolymers muindasitiri,kunyanya polima mvura kurapwa.
Mapolymers angashandiswa sei mukurapa kwemvura?
Mapolymers anobatsira zvakanyanya mukuchenesa mvura.Mupfungwa huru, basa remacheni aya nderekuparadzanisa chikamu chakasimba chemvura yetsvina kubva muchikamu chayo chemvura.Kana zvikamu zviviri zvemvura yakasviba zvaparadzaniswa, zviri nyore kupedzisa hurongwa nekuparadzanisa yakasimba uye kuchenesa mvura, ichisiya mvura yakachena kuitira kuti igone kuraswa zvakachengeteka kana kune mamwe mashandisirwo emabhizimisi.
Mupfungwa iyi, polima is a flocculant - chinhu chinopindirana nemarara akaturikwa mumvura kuita masumbu anonzi floc.Izvi zvinobatsira zvakanyanya mumararamiro ekuchenesa mvura, saka mapolymers anowanzo shandiswa ega kugonesa flocculation, iyo inogona kubvisa zviri nyore nyore.Nekudaro, kuti uwane mibairo yakanakisa kubva mukuita uku, mapolymer flocculants anowanzoshandiswa ne coagulants.
Coagulants inotora iyo flocculation process kuenda kune inotevera nhanho, ichiunganidza flocs pamwechete kuti igadzire gobvu remarara iro rinogona kuzobviswa kana kurapwa mberi.Polymer flocculation inogona kuitika isati yawedzerwa coagulants kana inogona kushandiswa kumhanyisa iyo electrocoagulation maitiro.Nekuti electrocoagulation ine zvese zvakanakira uye zvazvakaipira, kushandiswa kwepolymer flocculants kukwenenzvera maitiro izano rinokwezva kune maneja enzvimbo.
Mhando dzakasiyana dzemvura yekurapa ma polymers
Kugadziriswa kwemvura yepolymer kunogona kushanda nenzira dzakasiyana zvichienderana nerudzi rwemonomer inoshandiswa kugadzira iyo polymer cheni.Polymers kazhinji anowira muzvikamu zviviri zvakafara.Iwo ari cationic uye anionic, zvichireva kune hukama mhosva dzemacheni emamorekuru.
Anionic polymers mukurapa kwemvura
Anionic polymers inopomerwa zvakaipa.Izvi zvinovaita kuti vanyanyokodzera kutenderedza inorganic solids, senge ivhu, silt kana mamwe marudzi evhu, kubva mumarara.Mvura yakasviba kubva kumapurojekiti emigodhi kana indasitiri inorema inogona kunge yakapfuma mune iyi yakasimba yemukati, saka anionic mapolima anogona kunyanya kubatsira mumashandisirwo akadai.
Cationic polymers mukurapa kwemvura
Panyaya yekuchaja kwayo, cationic polymer inonyanya kupesana neanionic polymer nekuti ine chaji yakanaka.Iko kubhadharisa kwakanaka kwe cationic polymers kunoita kuti ive yakanaka yekubvisa organic solids kubva kune tsvina mhinduro kana musanganiswa.Nekuda kwekuti pombi dzesuweji dzevagari vemo dzinowanzove dzine huwandu hukuru hwezvinhu zvakasikwa, cationic mapolymers anowanzo shandiswa mumaguta ekuchenesa tsvina, kunyangwe nzvimbo dzekurima uye dzekugadzira chikafu dzinoshandisawo mapolima aya.
Yakajairika cationic polymers inosanganisira:
Polydimethyl diallyl ammonium chloride, polyamine, polyacrylic asidhi/sodium polyacrylate, cationic polyacrylamide, nezvimwe.
