Polyacrylamide ikoreshwa mu gutunganya amazi?

Polyacrylamide(PAM) ni polymer ifite uburemere bwinshi bwa molekile ikoreshwa cyane mu gutunganya amazi mu nzego zitandukanye. Ifite uburemere butandukanye bwa molekile, ionicities, n'imiterere ijyanye n'ikoreshwa ritandukanye, ndetse ishobora no guhindurwa kugira ngo ikoreshwe mu bihe bitandukanye. Binyuze mu gutiza ingufu z'amashanyarazi no gushyiramo polymer no guhuza, PAM ishobora guteza imbere ukwiyongera kw'ibice bihagaze by'amazi, ikarushaho kunoza ubwiza bw'amazi. Iyi nkuru izasuzuma uburyo PAM ikoreshwa n'ingaruka zayo mu gutunganya amazi mu nzego zitandukanye.

Mu gutunganya imyanda yo mu ngo, PAM ikoreshwa cyane cyane mu gutunganya imyanda no gukuraho amazi mu myanda. Mu kugabanya imiterere y'amashanyarazi no gukoresha uburyo bwo guhuza amazi, PAM ishobora kwihutisha kwegerana kw'ibintu bikomeye biri mu mazi kugira ngo bikore uduce duto tw'ibice binini. Utwo duce tworoshye guhagarara no kuyungurura, bityo bikavanaho imyanda mu mazi neza kandi bigagera ku ntego yo gusukura ubwiza bw'amazi. Gukoresha PAM bishobora kunoza imikorere yo gutunganya imyanda no kugabanya ikiguzi cyo kuyitunganya.

Mu bijyanye no gukora impapuro, PAM ikoreshwa cyane cyane nk'igikoresho cyo kubika impapuro, ubufasha mu kuyungurura, gukwirakwiza impapuro, nibindi. Iyo wongeyeho PAM, igipimo cyo kubika impapuro n'imigozi myiza mu mpapuro gishobora kunozwa, bikagabanya ikoreshwa ry'ibikoresho fatizo, kandi bikongera ubushobozi bwo kuyungurura no kubura amazi mu mpapuro. Byongeye kandi, PAM ishobora gukora nk'igikoresho kidakoresha silicon polymer stabilizer mu buryo bwo gusiba impapuro, bigatuma umweru n'urumuri by'impapuro birushaho kuba byiza.

Mu gutunganya amazi yanduye y’ibimera birimo inzoga,PAMikoreshwa cyane cyane mu gikorwa cyo gukura amazi mu myanda. Ku bijyanye no gukora inzoga hakoreshejwe ibikoresho fatizo bitandukanye no gutunganya amazi yanduye, ni ngombwa guhitamo polyacrylamide ya cationic ifite ionicity ikwiye n'uburemere bwa molekile. Gupima guhitamo hakoreshejwe igerageza rya beaker ni bumwe mu buryo bukunze gukoreshwa.

Amazi yanduye y’ibiryo, afite ibintu byinshi by’umwimerere n’ibintu bikomeye bivamo, akeneye uburyo bukwiye bwo kuyatunganya. Uburyo gakondo burimo gusya ibintu mu buryo bw’umubiri no kuyahindura mu buryo bwa biochemical. Ariko, mu bikorwa bifatika, polymer flocculants ikunze kuba ikenewe mu kubura amazi mu myanda no mu bindi bikorwa byo kuyatunganya. Inyinshi mu mashini zikoreshwa muri ubu buryo ni cationic polyacrylamide series products. Guhitamo poliacrylamide ikwiye bisaba gusuzuma ingaruka z’imihindagurikire y’ikirere (ubushyuhe) ku guhitamo flocculant, guhitamo uburemere bukwiye bwa molekile n’agaciro k’ingufu hashingiwe ku bunini bwa floc busabwa n’uburyo bwo kuyatunganya, n’ibindi bintu. Byongeye kandi, hakwiye kwitabwaho ibibazo nk’ibisabwa mu buryo n’ibikoresho ndetse n’ikoreshwa rya flocculants.

Mu mazi yanduye akoresha ikoranabuhanga n'amashanyarazi, PAM ikoreshwa cyane cyane nk'amaziFlocculantn'umuvuduko. Mu kugabanya imiterere y'amashanyarazi no gukoresha ingaruka zo guhuza amazi, PAM ishobora kwiyunga vuba no gushyira iyoni z'icyuma gikomeye mu mazi yanduye. Muri ubu buryo, muri rusange ni ngombwa kongeramo aside sulfurike mu mazi yanduye kugira ngo uhindure pH igere kuri 2-3 hanyuma wongereho ikintu kigabanya ubukana. Mu mashini ikurikiraho, koresha NaOH cyangwa Ca(OH)2 kugira ngo uhindure pH igere kuri 7-8 kugira ngo utange Cr(OH)3 precipitation. Hanyuma ongeramo coagulant kugira ngo uhindure hanyuma ukureho Cr(OH)3. Binyuze muri ubu buryo bwo gutunganya, PAM ifasha kunoza imikorere yo gutunganya amazi yanduye hakoreshejwe ikoranabuhanga no gushyiramo amashanyarazi no kugabanya ingaruka za iyoni z'icyuma gikomeye ku bidukikije.
