NhanganyayaOfThe USePolyacrylamide
Tatonzwisisa mashandiro uye mhedzisiro yemishonga yekurapa mvura zvakadzama. Kune marudzi akasiyana-siyana emhando zvichienderana nemabasa avo nemarudzi avo. Polyacrylamide ndeimwe yemapolymers ane linear polymer, uye cheni yayo yemamorekuru ine huwandu hwakati hwema radicals. Inogona kupinza zvidimbu zvakasimba zvakasungirirwa mumvura, ma bridge ions kana zvikamu zvakaunganidzwa kuita ma flocs makuru kuburikidza ne charge neutralization, kukurumidzisa sedimentation yezvidimbu zvakamiswa, kukurumidzisa kujeka kwemushonga, uye kunatsiridza mhedzisiro yekusefa. Kushandiswa kwayo kwakadzama kuchaunzwa sezviri pazasi kwauri.
1. Kushandiswa pakudiridza tsvina
Kana ikashandiswa pakudiridza tsvina, cationic polyacrylamide inogona kusarudzwa zvichienderana netsvina, iyo inogona kudiridza tsvina isati yapinda mufiriji yekusefa. Kana ichidiridza, inogadzira maflocs makuru, hainamati pajira rekusefa, uye haipararire panguva yekudiridza kwekusefa. Keke rematope rakakora uye kushanda zvakanaka kwemvura mumuviri kwakakwira.
2. Kushandiswa pakurapa mvura yakasviba yeorganic
Kana ikashandiswa pakurapa tsvina yemumba nemvura yakasviba, yakadai semvura yakasviba yechikafu nedoro, mvura yakasviba inobva muzvigayo zvekuchenesa tsvina yemumaguta, mvura yakasviba yedoro, mvura yakasviba yefekitori yeMSG, mvura yakasviba yeshuga, mvura yakasviba yekudya, nezvimwewo, cationic polyacrylamide inobatsira kupfuura anionic, nonionic uye inorganic salts kakawanda kana kagumi, nekuti rudzi urwu rwemvura yakasviba runowanzova nechaji isina kunaka.
3. Kucheneswa kwemvura isina kucheneswa kubva munzizi nemadhamu
Polyacrylamide inogona kushandiswa pakurapa mvura yemupombi nemvura yerwizi senzvimbo inobva mvura. Nekuda kwemuyero wayo mudiki, mhedzisiro yakanaka uye mutengo wayo wakaderera, kunyanya kana ikashandiswa pamwe chete ne inorganic flocculants, saka ichashandiswa mumiti yemvura se flocculant inobva kuRwizi Yangtze, Rwizi Yellow nedzimwe nzvimbo.
Zviri pamusoro apa kushandiswa kwakadzama kwepolyacrylamide. Semushonga wekuchenesa mvura, ine simba guru mukuchenesa tsvina. Zvisinei, pamusoro pekushandiswa kwayo kwakakosha muzvinhu zvitatu zviri pamusoro apa, inogonawo kushandiswa semushonga wekusimbisa uye zvimwe zvinowedzera mukugadzira mapepa kuti iwedzere mwero wekuchengetedza mafillers nemapigments, uye kuwedzera simba repepa; semushonga wemafuta, zvakaita sevhu rinodzivirira kuzvimba. Imushonga wekusimbisa acidity yemafuta; inogona kuita basa guru mukugadzira saizi yemachira, kushanda kwehukuru hwakagadzikana, saizi shoma, mwero wakaderera wekuputika kwemachira, uye pamusoro pejira rakatsetseka.
