Kuchapira malasha chomera Polyacrylamide ndi gulu polima. Iwo akhoza bwino kumveketsa bwino malasha kutsuka madzi, kupanga particles zabwino mu malasha kusamba madzi mwamsanga agglomerate ndi kuthetsa, ndi kuonjezera kuchira kuchuluka kwa peat, potero kukwaniritsa zotsatira za kupulumutsa madzi, kupewa kuipitsa, ndi zina kuwongolera dzuwa la kampani.
1. Polyacrylamide mankhwala oyamba:
Polyacrylamide ndi polima yofunikira yosungunuka m'madzi ndipo ili ndi zinthu zofunika monga flocculation, thickening, kukameta ubweya, kuchepetsa kukoka, ndi kubalalitsidwa. Zinthu izi zimasiyana malinga ndi ion yochokera. Choncho, chimagwiritsidwa ntchito m'zigawo mafuta, mchere processing, kuchapa malasha, zitsulo, makampani mankhwala, papermaking, nsalu, kuyenga shuga, mankhwala, kuteteza zachilengedwe, zomangira, ulimi ulimi ndi madipatimenti ena.
awiri. Zizindikiro zakuthupi ndi zamankhwala:
Mawonekedwe: tinthu tating'onoting'ono toyera kapena achikasu, okhutira ≥98%, mamolekyu olemera 800-14 miliyoni.
atatu. Kayendetsedwe kazinthu:
1. Gwiritsani ntchito mankhwalawa kuti mukwaniritse zapadera za flocculation ndi mlingo wochepa kwambiri.
2. Nthawi yochitira pakati pa mankhwalawa ndi madzi a malasha amadzi ndi yaifupi ndipo liwiro la zomwe zimachitika ndi lachangu. compact.
3. Izi zitha kugwiritsidwa ntchito pakukhazikitsa malasha slurry, kukhazikika kwa ma tailings, kulekanitsa kwa centrifugal, etc.
Zinayi. Mlingo:
Mlingo wa mankhwalawa umadalira mtundu wa malasha, mtundu wa madzi ndi kuchuluka kwa kutsuka kwa malasha pamalo okonzekera malasha.
zisanu. Momwe mungagwiritsire ntchito:
1. Sungunulani: Gwiritsani ntchito ziwiya zopanda chitsulo. Gwiritsani ntchito madzi oyera ndi kutentha kwa madzi osapitirira 60 ° C. Pang'onopang'ono ndi wogawana kufalitsa malasha kutsuka flocculant mu chidebe pamene kukhetsa madzi, kuti malasha kutsuka flocculant mokwanira analimbikitsa ndi madzi mu chidebe. Pambuyo kusonkhezera mosalekeza kwa mphindi 50-60, itha kugwiritsidwa ntchito. Limbikitsani mzere wa tsamba Kuthamanga kumatengera chidebe.
2. Kuwonjezera: Sungunulani flocculant yamalasha yosungunuka ndi madzi oyera ndikugwiritsa ntchito ndende pakati pa 0.02-0.2%. Gwiritsani ntchito valavu kuti muwongolere kutuluka kwake ndikuwonjezera mofanana pamadzi amatope a malasha. (Mungathenso kukonzekera mwachindunji flocculant ndi ndende pakati pa 0.02-0.2%.
6. Zolemba:
1. Ngati sichikugwiridwa bwino panthawi ya kusungunuka, chinthu chocheperako chosungunuka chosungunuka chidzawoneka ngati chili m'madzi. Iyenera kusefedwa kapena kudikirira pang'onopang'ono kusungunuka musanagwiritse ntchito, osakhudza momwe mungagwiritsire ntchito.
2. Ndalama zowonjezera ziyenera kukhala zochepa. Mochuluka kapena pang'ono sikungakwaniritse zoonekeratu flocculation kwenikweni. Wogwiritsa ntchitoyo asinthe mlingo molingana ndi mikhalidwe yosiyanasiyana monga mtundu wamadzi a malasha, kuthamanga kwa madzi ndi kuchuluka kwa kutsuka.
3. Ngati mlingo wa flocculant ndi wochepa ndipo zotsatira zake sizili bwino panthawi yogwiritsira ntchito, koma ngati mlingowo wawonjezeka, zingwe ndi zovuta zina zogona zidzachitika. Mukhoza kuchepetsa kapena kuonjezera ndende ya flocculant yankho ndi kuonjezera otaya mlingo kuonjezera mlingo wa flocculant. Kapena kusuntha malo owonjezera a flocculant chammbuyo kuti atalikitse nthawi yosakanikirana yamadzi amatope ndi malasha amathanso kuthana ndi vuto la pogona lomwe latchulidwa pamwambapa.
