Utumenyetso dusanzwe duhura na two mu gihe cyo guhitamo PAM

Polyacrylamide(PAM), nk'icyuma gikoreshwa cyane mu gutunganya imyanda ya polymer, gikoreshwa cyane mu buryo butandukanye bwo gutunganya imyanda. Ariko, abakoresha benshi bagiye bagira ubwumvikane buke mu gihe cyo guhitamo no gukoresha imyanda. Iyi nkuru igamije kugaragaza ubwo bwumvikane buke no gutanga ibisobanuro n'ibitekerezo bikwiye.

Kutumvikana nabi kwa 1: Uko uburemere bwa molekile burushaho kuba bwinshi, niko ubushobozi bwo gukora flocculation burushaho kwiyongera.

Mu guhitamo polyacrylamide, abantu benshi batekereza ko icyitegererezo gifite uburemere bunini bwa molekile kigomba kuba gifite ubushobozi bwo gukurura amazi. Ariko mu by'ukuri, hari amagana y'ibyitegererezo bya polyacrylamide, bikwiriye imiterere itandukanye y'amazi. Imiterere y'amazi yanduye akorwa n'inganda zitandukanye iratandukanye. Agaciro ka pH n'imyanda yihariye y'amazi atandukanye biratandukanye cyane. Bishobora kuba bifite aside, alkaline, neutral, cyangwa birimo amavuta, ibintu by'umwimerere, ibara, ibisigazwa, nibindi. Kubwibyo, biragoye ko ubwoko bumwe bwa polyacrylamide buhura n'ibikenewe byose mu gutunganya amazi yanduye. Uburyo bukwiye ni ukubanza guhitamo icyitegererezo binyuze mu igerageza, hanyuma ugakora ibizamini by'imashini kugira ngo umenye ingano nziza kugira ngo ugere ku ngaruka nziza kandi ihendutse.

Kutumvikana nabi kwa 2: Uko imiterere y'ibintu irushaho kuba myinshi, niko birushaho kuba byiza

Mu gutegura imiti ya polyacrylamide, abakoresha benshi bizera ko uko ingano yayo irushaho kuba nyinshi, ari na ko imiterere yayo irushaho kuba myiza. Ariko, iyi myumvire ntabwo ari yo. Mu by'ukuri, ingano ya PAM igomba kugenwa hakurikijwe imiterere yihariye y'imyanda n'imyanda. Muri rusange, imiti ya PAM ifite ingano ya 0.1%-0.3% ikwiriye gukoreshwa mu gusukura no gusya imyanda, mu gihe ingano yo gusukura imyanda mu mujyi no mu nganda ari 0.2%-0.5%. Iyo imyanda myinshi mu myanda, ingano ya PAM ishobora gukenera kongerwa uko bikwiye. Kubwibyo, ingano ikwiye igomba kugenwa binyuze mu igerageza mbere yo kuyikoresha kugira ngo hamenyekane ingaruka nziza zo kuyikoresha.

Kutumvikana nabi kwa 3: Uko igihe cyo gushonga no gukurura kirushaho kuba kirekire, niko bigenda neza

Polyacrylamide ni agace k'umweru gafite ishusho y'ubururu gakwiye gushonga neza kugira ngo gakore neza. Abakoresha benshi batekereza ko uko igihe cyo gushonga no gushonga ari kirekire, ari ko biba byiza, ariko mu by'ukuri si ko bimeze. Iyo igihe cyo gushonga ari kirekire cyane, bizatera gucika igice cy'uruhererekane rwa molekile rwa PAM kandi bigira ingaruka ku mikorere ya flocculation. Muri rusange, igihe cyo gushonga no gushonga ntikigomba kuba munsi y'iminota 30 kandi kigomba kongerwa uko bikwiye iyo ubushyuhe buri hasi mu gihe cy'itumba. Iyo igihe cyo gushonga no gushonga ari gito cyane, PAM ntizashonga neza, bizatuma idashobora gukora flocculation yihuta mu myanda. Kubwibyo, abakoresha bagomba kwemeza ko igihe gihagije cyo gushonga no gushonga iyo bayikoresheje kugira ngo barebe ko PAM ikora flocculation.

Kutumvikana nabi 4: Ionicity/Ionic degree niyo shingiro ryonyine ryo guhitamo

Kimwe mu bimenyetso by'ingenzi bya polyacrylamide, ionicity yerekeza ku ionic charge mbi na nziza hamwe n'ubucucike bwayo. Abantu benshi bita cyane ku ionicity iyo bagura, bibwira ko uko izamuka ari ko irushaho kuba nziza. Ariko mu by'ukuri, urwego rwa ionicity rufitanye isano n'ingano y'uburemere bwa molekile. Uko ionicity irushaho kuba nyinshi, niko uburemere bwa molekile buba buto, kandi igiciro kikaba kinini. Mu guhitamo, uretse ionicity, hari ibindi bintu bigomba kwitabwaho, nko imiterere yihariye y'amazi, ibisabwa kugira ngo flocculation effect, nibindi. Kubwibyo, moderi ntishobora gutoranywa hashingiwe gusa ku rugero rwa ionization. Hakenewe ibizamini byinshi kugira ngo hamenyekane moderi ikenewe.

Nk'umuntuumuti wo mu mazi, polyacrylamide igira uruhare runini mu nganda zitunganya amazi. Iyo ukeneye guhitamo ibikenewe bikubereye, nyamuneka ndumva.
