Polyacrylamide(Pam), ngati madzi ofunika amadzi othandizira, amagwiritsidwa ntchito kwambiri m'minda yosiyanasiyana ya mafakitale. Komabe, kusungunuka Pam kumakhala kovuta kwa ogwiritsa ntchito ambiri. Pam masamba omwe amagwiritsidwa ntchito mu madzi osungira mafakitale amabwera mitundu iwiri: ufa wowuma ndi emulsion. Nkhaniyi idzetsa njira yophweka yamitundu iwiri ya Pam mwatsatanetsatane kuti awonetsetse kuti ogwiritsa ntchito amapeza zotsatira zabwino kwambiri.
Njira yokhumudwitsa yachindunji ndi njira yosavuta kwambiri komanso yosavuta kwambiri. Njirayi ndiyoyenera pakudya ufa ndi kulemera kwam'munsi ndipo ndikosavuta kusungunula. Nayi masitepe apadera:
Konzani chidebe: Sankhani zodetsa zoyera, zowuma, zowuma, zokulirapo mokwanira kuti zigwiritsidwe ntchito ufa ndi madzi. Osagwiritsa ntchito zotengera zachitsulo kapena zotengera ndi madontho achitsulo.
Onjezani zosungunulira: Onjezani madzi oyenera.
Kusunthidwa: Yambitsani chosokoneza. Mukamayambitsa, onetsetsani kuti wotsogolera wamizidwa kwathunthu mu yankho popewa thovu. Liwiro losangalatsa siliyenera kukhala lalitali kwambiri popewa kuwonongeka kwa pamtole.
Onjezani Pam ufa: Pang'onopang'ono onjezani Pampu yofunikira mu chidebe pomwe mukusunthika modekha kuti mupewe fumbi lowuluka. Pitilizani kuyambitsa yankho loti pakhale poyera lomwe limabalalika kwambiri.
Yembekezerani kusungunuka: Sungani zolimbikitsa ndikuwona kusungunuka kwa Pam ufa. Nthawi zambiri, pamafunika kusunthidwa kwa maola 1 mpaka awiri mpaka pams yomwe imasungunuka kwathunthu.
Chongani kusungunuka: Mukamaliza kusungunuka, pezani ngati zasungunuka kwathunthu poyang'ana kuwonekera kapena njira yotsimikizika ya yankho. Ngati tinthu tating'onoting'ono kapena timiyala tating'onoting'ono tikuwoneka, pitilizani kusangalatsa mpaka kusungunuka kwathunthu. Ngati zolemera za Pam ndizokwera kwambiri ndipo kuwonongeka ndikosachedwa kwambiri, zitha kuphikanso moyenera, koma siziyenera kupitirira 60 ° C.
Konzani chidebe ndi zida: sankhani chidebe chachikulu kuti chitsimikizire kuti pali malo okwanira osakanikirana. Khalani ndi chosokoneza kapena ndodo yokonzekera kuonetsetsa kuti yankho limasakaniza bwino.
Konzani yankho: Onjezani madzi ndi pamlomo nthawi imodzi, ndipo yambitsani nthawi imodzi kuti muwonetsetse kuti emulsion ndi madzi ndi osakanikirana.
Sinthani nkhawa zomaliza: Kukhazikika kotsiriza kwa Pam emulsion kuyenera kuwongoleredwa pa 1-5% kuti atsimikizire momwe mwakhalira pokonza zokhala. Ngati mukufuna kusintha ndendeyo, pitilizani kuwonjezera madzi kapena kuwonjezera pamtunda.
Pitilizani Kusangalatsa: Mukatha kuwonjezera Pam emulsion, pitilizani kusangalatsa yankho kwa mphindi 15-25. Izi zimathandiza Pam ma mamolekyulu ofalikira kwathunthu ndikusungunuka, ndikuwonetsetsa kufalitsa kwawo m'madzi.
Pewani Kusangalatsa Kwambiri: Ngakhale kuti kusandulika koyenera kumathandiza kusungunuka pamphu, kwambiri kungayambitse kuwonongeka kwa ma mamolekyulu, kuchepetsa zotsatira zake. Chifukwa chake, sinthani liwiro losangalatsa ndi nthawi.
Kusunga ndi kugwiritsa ntchito: Sungani Pampu yosungunuka mumdima, yowuma, kuonetsetsa kuti kutentha ndikoyenera. Pewani dzuwa mwachindunji kuti mulepheretse Pam. Mukamagwiritsa ntchito, onetsetsani kuti kufanana ndi yankho lopewa kukhudzidwa chifukwa chobwezera chifukwa chogawa.
