Kusamvetsetsana komwe kumachitika nthawi zambiri posankha PAM

Polyacrylamide(PAM), monga chopopera madzi chogwiritsidwa ntchito kwambiri, chimagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana zoyeretsera zinyalala. Komabe, ogwiritsa ntchito ambiri akumana ndi kusamvetsetsana panthawi yosankha ndi kugwiritsa ntchito. Nkhaniyi ikufuna kuulula kusamvetsetsana kumeneku ndikupereka kumvetsetsa kolondola ndi malingaliro.

Kusamvetsetsana 1: Kulemera kwa mamolekyulu kukakhala kwakukulu, mphamvu ya flocculation imakwera kwambiri.

Posankha polyacrylamide, anthu ambiri amaganiza kuti chitsanzo chokhala ndi kulemera kwakukulu kwa mamolekyulu chiyenera kukhala ndi mphamvu yowonjezereka ya flocculation. Koma kwenikweni, pali mazana a mitundu ya polyacrylamide, yomwe ndi yoyenera mikhalidwe yosiyanasiyana yamadzi. Mtundu wa madzi otayidwa opangidwa ndi mafakitale m'mafakitale osiyanasiyana ndi wosiyana. Mtengo wa pH ndi zonyansa zinazake zamitundu yosiyanasiyana yamadzi ndizosiyana kwambiri. Zitha kukhala acidic, alkaline, neutral, kapena zili ndi mafuta, organic matter, mtundu, sediment, ndi zina zotero. Chifukwa chake, zimakhala zovuta kuti mtundu umodzi wa polyacrylamide ukwaniritse zosowa zonse za chithandizo cha madzi otayidwa. Njira yoyenera ndi kusankha kaye chitsanzo kudzera mu zoyeserera, kenako kuchita mayeso amakina kuti mudziwe mlingo woyenera kuti mupeze zotsatira zotsika mtengo kwambiri.

Kusamvetsetsana 2: Kuchuluka kwa kasinthidwe, kumakhala bwino

Pokonzekera mayankho a polyacrylamide, ogwiritsa ntchito ambiri amakhulupirira kuti kuchuluka kwa madzi m'madzi kukakhala kwakukulu, mphamvu ya madzi m'madzi imakula. Komabe, lingaliro ili si lolondola. Ndipotu, kuchuluka kwa madzi m'madzi a PAM kuyenera kutsimikiziridwa malinga ndi momwe madzi amayendera komanso matope amakhalira. Kawirikawiri, mayankho a PAM okhala ndi kuchuluka kwa madzi m'madzi a 0.1%-0.3% ndi oyenera kuchotsedwa madzi m'madzi ndi m'matope, pomwe kuchuluka kwa madzi m'madzi am'matauni ndi m'mafakitale ndi 0.2%-0.5%. Ngati pali zinyalala zambiri m'madzi am'matauni, kuchuluka kwa madzi m'madzi a PAM kungafunike kuwonjezeredwa moyenera. Chifukwa chake, kuchuluka kwa madzi m'madzi kuyenera kutsimikiziridwa kudzera mu zoyeserera musanagwiritse ntchito kuti muwonetsetse kuti kugwiritsa ntchito bwino kudzakhala ndi zotsatira zabwino.

Kusamvetsetsana 3: Nthawi yayitali yosungunuka ndi kusakaniza, zimakhala bwino

Polyacrylamide ndi tinthu tating'onoting'ono toyera tomwe timafunika kusungunuka kwathunthu kuti tipeze zotsatira zabwino kwambiri. Ogwiritsa ntchito ambiri amaganiza kuti nthawi yosungunuka ndi kusakaniza ikatalika, zimakhala bwino, koma kwenikweni sizili choncho. Ngati nthawi yosakaniza ndi yayitali kwambiri, ingayambitse kusweka pang'ono kwa unyolo wa mamolekyu a PAM ndikukhudza magwiridwe antchito a flocculation. Nthawi zambiri, nthawi yosungunuka ndi kusakaniza siyenera kukhala yochepera mphindi 30 ndipo iyenera kuwonjezeredwa moyenera kutentha kuli kochepa m'nyengo yozizira. Ngati nthawi yosungunuka ndi kusakaniza ndi yochepa kwambiri, PAM sidzasungunuka kwathunthu, zomwe zingapangitse kuti munthu asathe kuchita bwino flocculation mwachangu m'madzi otayira. Chifukwa chake, ogwiritsa ntchito ayenera kuonetsetsa kuti nthawi yokwanira yosungunuka ndi kusakaniza ikagwiritsidwa ntchito kuti atsimikizire kuti PAM ikuyenda bwino.

Kusamvetsetsana 4: Ionicity/Ionic digiri ndiyo maziko okhawo osankhidwira

Monga chimodzi mwa zizindikiro zofunika kwambiri za polyacrylamide, ionicity imatanthauza mphamvu ya ionic yoipa komanso yabwino komanso kuchuluka kwake. Anthu ambiri amasamala kwambiri za mphamvu ya ioni akamagula, poganiza kuti kukwera kwake kumakhala bwino. Koma kwenikweni, mphamvu ya ionicity imakhudzana ndi kukula kwa kulemera kwa mamolekyulu. Ionicity ikakwera, kulemera kwa mamolekyulu kumakhala kochepa, komanso mtengo wake umakwera. Posankha, kuwonjezera pa mphamvu ya ionicity, zinthu zina ziyenera kuganiziridwa, monga momwe madzi amakhalira, zofunikira pa flocculation effect, ndi zina zotero. Chifukwa chake, chitsanzocho sichingasankhidwe kutengera kuchuluka kwa mphamvu ya ioni. Kuyesa kwina kumafunika kuti mudziwe chitsanzo chofunikira.

Mongaflocculant, polyacrylamide imagwira ntchito yofunika kwambiri mumakampani oyeretsera madzi. Mukafuna kusankha zofunikira zomwe zikukuyenererani, chonde nditumizireni uthenga.
