Polyacrylamide (PAM) ndi polima liniya ndi flocculation, adhesion, kuchepetsa kukoka, ndi zina. Monga aPolymer Organic Flocculant, amagwiritsidwa ntchito kwambiri pokonza madzi. Mukamagwiritsa ntchito PAM, njira zoyenera zogwirira ntchito ziyenera kutsatiridwa kuti mupewe kuwonongeka kwa mankhwala.
Njira Yowonjezera PAM
ZaPAM yolimba, imafunika kuwonjezeredwa kumadzi ikasungunuka. Pamakhalidwe osiyanasiyana amadzi, mitundu yosiyanasiyana ya PAM iyenera kusankhidwa, ndi mayankho amagawidwa mosiyanasiyana. Powonjezera polyacrylamide, chidwi chiyenera kuperekedwa ku mfundo zotsatirazi:
Mayeso a Jar:Dziwani zomwe zili bwino komanso mulingo wake kudzera mu mayeso a mtsuko. Mu mayeso mtsuko, pang`onopang`ono kuonjezera mlingo wa polyacrylamide, kuona flocculation zotsatira, ndi kudziwa mulingo woyenera kwambiri mlingo.
Kukonzekera PAM Aqueous Solution:Popeza anionic PAM (APAM) ndi nonionic PAM (NPAM) ali ndi kulemera kwakukulu kwa maselo ndi mphamvu zamphamvu, anionic polyacrylamide nthawi zambiri amapangidwa mu njira yamadzimadzi yokhala ndi 0.1% (kutanthauza zolimba) ndi madzi opanda mchere, osalowerera ndale. Sankhani zitsulo zokhala ndi enameled, malata, kapena zidebe zapulasitiki m'malo mwa zotengera zachitsulo monga ma ayoni achitsulo amayambitsa kuwonongeka kwa mankhwala a PAM onse. Pokonzekera, polyacrylamide imafunika kuwaza mofanana m'madzi osonkhezera ndikutenthetsa moyenerera (<60°C) kuti ifulumire kusungunuka. Mukasungunuka, tcheru chiyenera kuperekedwa kuti muwonjezere mankhwala mofanana komanso pang'onopang'ono mu dissolve ndi njira zokondoweza komanso zotenthetsera kuti mupewe kulimba. Njira yothetsera vutoli iyenera kukonzedwa pa kutentha koyenera, ndipo kumeta ubweya wautali komanso woopsa kuyenera kupewedwa. Ndikofunikira kuti chosakaniza chizizungulira pa 60-200 rpm; apo ayi, zidzayambitsa kuwonongeka kwa polima ndikukhudza momwe mungagwiritsire ntchito. Dziwani kuti yankho lamadzi la PAM liyenera kukonzedwa nthawi yomweyo musanagwiritse ntchito. Kusungirako kwa nthawi yaitali kudzatsogolera kuchepa kwapang'onopang'ono kwa ntchito. Pambuyo powonjezera flocculant amadzimadzi yothetsera kuyimitsidwa, kusonkhezera mwamphamvu kwa nthawi yaitali kudzawononga flocs yomwe yapangidwa.
Dosing Zofunika:Gwiritsani ntchito chipangizo cha dosing kuti muwonjezere PAM. Kumayambiriro kwa zomwe zimachitika powonjezera PAM, ndikofunikira kuonjezera mwayi wolumikizana pakati pa mankhwala ndi madzi kuti athandizidwe momwe angathere, kuwonjezera kusonkhezera, kapena kuonjezera kuthamanga.
Zomwe Muyenera Kuzidziwa Powonjezera PAM
Nthawi Yoyimitsa:Mitundu yosiyanasiyana ya PAM ili ndi nthawi zosiyanasiyana zotayika. Cationic PAM ili ndi nthawi yaifupi yotayika, pomwe PAM ya anionic ndi nonionic ili ndi nthawi yayitali yosungunuka. Kusankha nthawi yoyenera kusungunuka kungathandize kusintha flocculation effect.
Mlingo ndi Kuyikira Kwambiri:Mlingo woyenera ndiye chinsinsi chothandizira kukwaniritsa bwino kwambiri kwa flocculation. Mlingo wochulukirawu ungapangitse kuti ma colloid achuluke kwambiri komanso tinthu tating'onoting'ono tating'onoting'ono, kupanga matope akuluakulu m'malo mwa flocs, zomwe zimakhudza mtundu wa utsi.
Zosakaniza Zosakaniza:Kuonetsetsa kusakaniza kokwanira kwa PAM ndi madzi otayira, zipangizo zoyenera zosakaniza ndi njira ziyenera kusankhidwa. Kusakanikirana kosagwirizana kungayambitse kuwonongeka kosakwanira kwa PAM, potero kumakhudza zotsatira zake za flocculation.
Mkhalidwe Wachilengedwe wa Madzi:Zinthu zachilengedwe monga pH mtengo, kutentha, kupanikizika, etc., zidzakhudzanso zotsatira za flocculation za PAM. Kutengera momwe madzi akutayira alili abwino, magawowa angafunike kusintha kuti apeze zotsatira zabwino.
Dosing motsatizana:M'dongosolo la madontho ambiri, ndikofunikira kuti mumvetsetse momwe madontho amayendera a othandizira osiyanasiyana. Mayendedwe olakwika a dosing angakhudze kuyanjana pakati pa PAM ndi ma colloids ndi tinthu tating'onoting'ono tomwe timayimitsidwa, potero zimakhudza momwe flocculation imayendera.
Polyacrylamide(PAM) ndi polima yosunthika yokhala ndi ntchito zosiyanasiyana, makamaka pochiza madzi. Kuti muwonjezere mphamvu zake ndikupewa kuwononga, ndikofunikira kutsatira njira zoyenera zogwirira ntchito. Poganizira mozama zinthu monga nthawi ya kusungunuka, mlingo, kusakaniza mikhalidwe, chilengedwe cha madzi, ndi ndondomeko ya dosing, mutha kugwiritsa ntchito bwino PAM kuti mukwaniritse zotsatira zomwe mukufuna ndikuwongolera madzi.
