Polyaluminum chloride e sebediswa haholo bakeng sa phepelo ya metsi a ditoropong le tlhoekiso ya drainage: metsi a noka, metsi a polokelo, metsi a ka tlasa lefatshe; tlhoekiso ya phepelo ya metsi a diindastering, kalafo ya dikgwerekgwere tsa ditoropong, ho fumanwa ha dintho tse thusang metsing a ditshila a diindasteri le masalla a ditshila, ho kgothaletsa ho qhibidiha ha mashala a silafaditsweng metsing a ditshila a hlatswang mashala, tlhahiso ya starch Ho sebediswa hape ha starch; polyaluminum chloride e ka hlwekisa metsi a ditshila a diindasteri a fapaneng, a kang: ho hatisa le ho daya metsi a ditshila, metsi a ditshila a letlalo, metsi a ditshila a nang le fluorine, metsi a ditshila a tshepe e boima, metsi a ditshila a nang le oli, metsi a ditshila a etsang pampiri, metsi a ditshila a hlatswang mashala, ho tjheka metsi a ditshila, ho etsa metsi a ditshila a metallurgical, ho sebetsana le nama, jj.; Polyaluminum chloride bakeng sa kalafo ya dikgwerekgwere: boholo ba ho etsa pampiri, ho hlwekisa tsoekere, ho lahla, ho thibela matheba a masela, catalyst carrier, ho lokisa meriana ka potlako, ho lokisa samente, thepa e tala ya botle.
Letšoao la boleng ba PAC (polyaluminum chloride)
Ke matšoao afe a mararo a bohlokoa ka ho fetisisa a boleng ba PAC (polyaluminum chloride)? Letswai, boleng ba PH, le bokahare ba alumina tse etsang qeto ea boleng ba polyaluminum chloride ke matšoao a mararo a bohlokoa ka ho fetisisa a boleng ba polyaluminum chloride.
1. Letswai.
Tekanyo ea hydroxylation kapa alkalization ea mofuta o itseng ho PAC (polyaluminum chloride) e bitsoa tekanyo ea basicity kapa alkalinity. Ka kakaretso e bontšoa ke karolelano ea molar ea aluminium hydroxide B=[OH]/[Al] percentage. Letsoai ke e 'ngoe ea litšupiso tsa bohlokoa ka ho fetisisa tsa polyaluminum chloride, e amanang haufi-ufi le phello ea flocculation. Ha mahloriso a metsi a tala a phahame 'me letsoai le phahame, phello ea flocculation e ba betere. Ha re akaretsa, ka har'a turbidity ea metsi a tala ea 86~10000mg/L, letsoai le letle ka ho fetisisa la polyaluminum chloride ke 409~853, 'me litšobotsi tse ling tse ngata tsa polyaluminum chloride li amana le letsoai.
2. Boleng ba pH.
PH ea tharollo ea PAC (polyaluminum chloride) le eona ke sesupo sa bohlokoa. E emela bongata ba OH- boemong bo lokolohileng tharollong. Boleng ba pH ba polyaluminum chloride hangata boa eketseha ka keketseho ea basicity, empa bakeng sa lino tse nang le metsoako e fapaneng, ha ho na kamano e tsamaellanang pakeng tsa boleng ba pH le basicity. Metsi a nang le letsoai le tšoanang a na le boleng bo fapaneng ba pH ha mahloriso a fapane.
3. Bokahare ba alumina.
Boleng ba alumina ho PAC (polyaluminum chloride) ke tekanyo ea likarolo tse sebetsang tsa sehlahisoa, tse nang le kamano e itseng le bongata bo lekanyelitsoeng ba tharollo. Ka kakaretso, ha bongata bo lekanyelitsoeng bo le boholo, boleng ba alumina bo ba holimo. Boleng ba polyaluminum chloride bo amana le bongata ba alumina, 'me boea boa eketseha ka keketseho ea bongata ba alumina. Tlas'a maemo a tšoanang le mahloriso a tšoanang a alumina, boea ba polyaluminum chloride bo tlase ho feta ba aluminium sulfate, e leng se thusang ho tsamaisoa le ho sebelisoa haholoanyane.
