Mokhoa oa ho khetholla mofuta oa ion oa polyacrylamide

Ho ea ka mofuta oa ione, polyacrylamide e ka aroloa ka: li-anionic polyacrylamide ,cationic polyacrylamide e le non-ionic polyacrylamide.

Moetsi oa polyacrylamide o tseba mofuta oa polyacrylamide ion:

Bahlahisi ba Polyacrylamide ba na le lilaboratori tsa litsebi. Ntle le ho leka lits'oants'o tsa mahlale tsa lihlahisoa tsa letsatsi le letsatsi, mosebetsi oa laboratori le ona o hloka ho leka liteko tsa kantle. Ka tloaelo, ha o fumana sampole e kantle, mofuta oa sehlahisoa oa ione o tlameha ho fumanoa pele. Joale o ka khetholla mofuta oa ion joang? Karabo ke hore: lits'oants'o tsa tekheniki ea ho fumana mehlala ea kantle ho naha. Anionic polyacrylamide le non-ionic polyacrylamide li khetholloa ka ho lemoha tekanyo ea hydrolysis. Tekanyo ea hydrolysis ea anionic polyacrylamide e ka ba 25, 'me degree ea hydrolysis ea non-ionic polyacrylamide e haufi le 5. Cationic polyacrylamide e khetholloa ka ho fumana degree ea ion, mme degree ea ion ea lihlahisoa tsa phofo e omileng hangata e fetoha lipakeng tsa 10-60.

Mokhoa oa ho khetholla mofuta oa ion ea polyacrylamide ka teko e bonolo:

Mokhoa oa ho khetholla mofuta oa ion oa polyacrylamide ha basebetsi ba le sebakeng sa kamora ho rekisa kapa ba se na lisebelisoa tsa liteko? Pele, re hloka ho ba le mehlala ea anionic polyacrylamide le cationic polyacrylamide, ebe re qhala lihlahisoa tsena tse peli ka thoko bakeng sa ts'ebeliso. Ebe o qhala sehlahisoa se hlokang ho lemoha mofuta oa ion, ebe o se khetholla ka karabelo ea yin le yang. Tšela tharollo ea anionic polyacrylamide tharollo ea sehlahisoa se tla hlahlojoa. Haeba palo e kholo ea li-flocs tse tšoeu e hlaha, ho bolela hore sampole e lekiloeng ke cationic polyacrylamide. Haeba ho se na karabelo, ho bolela hore ha e na ionic kapa anionic. Ebe o khetholla ka tharollo ea cationic polyacrylamide, palo e nyane ea li-flocs e bonts'a hore sehlahisoa se lekiloeng ha se ionic polyacrylamide, mme boholo ba li-flocs bo supa hore sampole e lekiloeng ke anionic polyacrylamide.

Bohlokoa ba ho tseba mofuta oa polyacrylamide ion:

Ha o sa tsebe hore na ho sebelisoa sehlahisoa sefe sa phallo sebakeng, ho khetholla mofuta oa polyacrylamide ion ho ka thusa basebelisi ho lekola mefuta le ho fumana lihlahisoa tse lumellanang le metsi a litšila a sebakeng seo kapele.

Ithute ho khetholla mofuta oa polyacrylamide ion, molemong oa hore basebelisi ba utloisise sehlahisoa hantle, ba sebelise sehlahisoa se nang le thepa e ntle, ba e hlokomele, 'me ba ele hloko barekisi ba babe ba thetsang bareki
