PAM bakeng sa kalafo ea metsi
Selelekela
PAM (Polyacrylamide) ke mofuta oa polymer o sebelisoang lits'ebetsong tse fapaneng, ho kenyeletsoa le kalafo ea metsi. Polyacrylamide e sebelisoa hangata e le setlolo sa ho phaphamala lits'ebetsong tsa kalafo ea metsi ho ntlafatsa ho lula ha likaroloana tse emisitsoeng, ho etsa hore ho be bonolo ho arola lintho tse tiileng ho metsi.
Polyacrylamide (PAM) ke motsoako oa polymer o sebelisoang haholo lefapheng la kalafo ea metsi. E tla ka mefuta e mengata e fapaneng, ho kenyeletsoa le e seng ea ionic, ea cationic, le ea anionic.

Likopo
Setlolo sa Floculant:Hangata Polyacrylamide e sebelisoa e le sesebelisoa sa ho thiba metsi ha ho phekoloa metsi ho tlosa lintho tse tiileng tse emisitsoeng, lintho tse nyenyane le li-colloid le ho li kopanya hore e be li-floc tse kholoanyane ho nolofatsa ho senngoa ha metsi kapa ho sefshoa. Ho thiba metsi hona ho thusa ho ntlafatsa ho hlaka ha metsi le ho pepeneneng.
Sesebelisoa sa ho ntlafatsa matla a ho ntsha metsi:Polyacrylamide e ka etsa metsoako e nang le li-ion tsa tšepe ho ntlafatsa phello ea precipitant. Ha ho phekoloa li-ion tsa tšepe tse nang le metsi a litšila, tšebeliso ea polyacrylamide e ka ntlafatsa phello ea pula le ho fokotsa litaba tsa li-ion tsa tšepe metsing a litšila.
Se thibelang ho ruruha:Mokhoeng oa ho phekola metsi, polyacrylamide e ka boela ea sebelisoa e le thibelo ea sekala ho thibela ho hola holim'a liphaephe le lisebelisoa. E ntlafatsa ho leka-lekana ha li-ion tsa metsi, e thibela ho beoa ha lintho tse qhibilihisitsoeng ka metsing, 'me e fokotsa ho thehoa ha sekala.
Ntlafatso ea boleng ba metsi:Polyacrylamide e ka boela ea sebelisoa ho ntlafatsa boleng ba metsi maemong a mang, joalo ka ho eketsa sekhahla sa ho senngoa ha lintho tse tiileng tse emisitsoeng ka metsing, ho fokotsa ho thehoa ha seretse, jj.
Ho tiea ha mobu:Ho tiiseng le ntlafatsong ea mobu, polyacrylamide e ka sebelisoa ho ntlafatsa botsitso le ho hanyetsa mafome mobung, ka hona ho ntlafatsa thepa ea 'mele ea mobu.
Ho lokela ho hlokomeloa hore tekanyo ea polyacrylamide e lokela ho laoloa ka hloko nakong ea tšebeliso ho qoba litlamorao tse mpe tikolohong. Ho feta moo, tšebeliso e itseng e itšetlehile ka litlhoko tse itseng tsa kalafo ea metsi le litšobotsi tsa boleng ba metsi.
Nka khetha lik'hemik'hale tse nepahetseng joang bakeng sa ts'ebeliso ea ka?
O ka re bolella boemo ba kopo ea hau, joalo ka mofuta oa letamo la ho sesa, litšobotsi tsa metsi a litšila a indasteri, kapa mokhoa oa hona joale oa kalafo.
Kapa, ka kopo fana ka letshwao kapa mohlala wa sehlahiswa seo o se sebedisang hajwale. Sehlopha sa rona sa botekgeniki se tla kgothaletsa sehlahiswa se loketseng ka ho fetisisa bakeng sa hao.
Hape o ka re romella disampole bakeng sa tlhahlobo ya laboratori, mme re tla etsa dihlahiswa tse lekanang kapa tse ntlafetseng ho latela ditlhoko tsa hao.
Na o fana ka lits'ebeletso tsa OEM kapa tsa mabitso a poraefete?
E, re tšehetsa ho iketsetsa mabitso, ho paka, ho etsa lintho ka mokhoa o ikhethileng, jj.
Na lihlahisoa tsa hau li na le setifikeiti?
E. Lihlahisoa tsa rona li netefalitsoe ke NSF, REACH, BPR, ISO9001, ISO14001 le ISO45001. Re boetse re na le litokelo tsa molao tsa naha tsa boqapi 'me re sebetsa le lifeme tse kopanetsoeng bakeng sa liteko tsa SGS le tlhahlobo ea carbon footprint.
Na o ka re thusa ho ntshetsa pele dihlahiswa tse ntjha?
E, sehlopha sa rona sa botekgeniki se ka thusa ho ntshetsa pele diforomo tse ntjha kapa ho ntlafatsa dihlahiswa tse seng di ntse di le teng.
Ho nka nako e kae hore o arabe lipotso?
Araba nakong ea lihora tse 12 matsatsing a tloaelehileng a mosebetsi, 'me u ikopanye le uena ka WhatsApp/WeChat bakeng sa lintho tse potlakileng.
Na o ka fana ka tlhahisoleseding e felletseng ya ho romela thepa kantle ho naha?
E ka fana ka sete e felletseng ea tlhahisoleseling joalo ka invoice, lethathamo la ho paka, bili ea thepa, setifikeiti sa tšimoloho, MSDS, COA, jj.
Tšebeletso ea kamora thekiso e kenyelletsa eng?
Fana ka tšehetso ea botekgeniki kamora thekiso, ho sebetsana le litletlebo, ho latela thepa, ho ntša hape kapa ho fumana puseletso bakeng sa mathata a boleng, jj.
Na o fana ka tataiso ea tšebeliso ea sehlahisoa?
E, ho kenyeletsoa le litaelo tsa tšebeliso, tataiso ea tekanyo, lisebelisoa tsa koetliso ea botekgeniki, jj.
