Re se re utloisisa ka botlalo mesebetsi le litlamorao tsa li-agents tsa ho hloekisa metsi. Ho na le lihlopha tse ngata tse fapaneng ho latela mesebetsi le mefuta ea tsona. Polyacrylamide ke e 'ngoe ea li-polymer tse melang,' me ketane ea eona ea molek'hule e na le palo e itseng ea radicals. E ka monya likaroloana tse tiileng tse emisitsoeng ka metsing, li-ion tsa borokho kapa likaroloana tse kopaneng ho li-flocs tse kholo ka ho se nke lehlakore, ho potlakisa sedimentation ea likaroloana tse emisitsoeng, ho potlakisa ho hlakisoa ha tharollo, le ho ntlafatsa phello ea ho sefa. Tšebeliso e qaqileng ea eona e tla hlahisoa ka tlase ho uena.
1. Sebelisa ho tlosa metsi a litšila
Ha e sebelisoa bakeng sa ho ntša metsi a litšila, cationic polyacrylamide e ka khethoa ho ea ka sludge, e ka khonang ho ntša metsi a litšila pele seretse se kena ka mochine oa khatiso. Ha e nosetsa, e hlahisa li-flocs tse kholo, ha e khomarele lesela la filthara, 'me ha e qhalane nakong ea mochine oa khatiso. Kaka ea seretse e teteaneng 'me katleho ea ho ntša metsi e phahame.
2. Sebelisa ho phekola metsi a litšila a manyolo
Ha e sebelisoa ho phekola likhoerekhoere tsa ka tlung le metsi a litšila a manyolo, joalo ka metsi a litšila a lijo le joala, metsi a litšila a tsoang litsing tsa likhoerekhoere tsa litoropo, metsi a litšila a biri, metsi a litšila a fektheri ea MSG, metsi a litšila a tsoekere, metsi a litšila, joalo-joalo, phello ea cationic Polyacrylamide e molemo ho feta. anionic, nonionic le inorganic salts makhetlo a 'maloa kapa makhetlo a mashome holimo, hobane mofuta ona oa metsi a litšila hangata o na le tefiso e mpe.
3. Tlhoekiso ea metsi a tala linokeng le matšeng
Polyacrylamide e ka sebelisoa bakeng sa kalafo ea metsi a pompo ka metsi a noka e le mohloli oa metsi. Ka lebaka la tekanyo ea eona e tlaase, phello e ntle le litšenyehelo tse tlaase, haholo-holo ha e sebelisoa hammoho le li-flocculants tse sa tloaelehang, kahoo e tla sebelisoa limela tsa metsi e le flocculant ho tloha Nōkeng ea Yangtze, Yellow River le likotlolo tse ling.
Ka holimo ke tšebeliso e qaqileng ea polyacrylamide. Joaloka moemeli oa ho hloekisa metsi, e na le ts'ebetso e eketsehileng ea ho hloekisa likhoerekhoere. Leha ho le joalo, ntle le tšebeliso ea eona ea bohlokoa likarolong tse tharo tse ka holimo, e ka boela ea sebelisoa e le moemeli oa ho matlafatsa le lisebelisoa tse ling ho etsa pampiri ho eketsa lebelo la ho boloka li-fillers le li-pigments, le ho eketsa matla a pampiri; e le li-additives tsa oli, tse kang letsopa le khahlanong le ho ruruha Ke moemeli o teteaneng bakeng sa acidification ea oli; e ka bapala karolo e kholo molemong oa ho etsa boholo ba masela, ts'ebetso e tsitsitseng ea boholo, boholo bo fokolang, sekhahla se tlase sa ho robeha, le bokaholimo ba masela a boreleli.
