Aluminium sulfate bakeng sa matamo
Kenyelletso
Aluminium sulfate, e tsejoang ka kakaretso ea Alum, ke k'hemiti ea kalafo e sebelisoang hohle molemong oa ho lokisa le letamong la letamo la ho ntlafatsa boleng ba metsi le ho hlaka. Sulfate ea rona ea Aluminium ke sehlahisoa sa sehlopha se hlophiselitsoeng ka botlalo ho sebetsana le litaba tse fapaneng tse amanang le metsi, li netefatsa tikoloho ea ho sesa.

LINTHO TSE HLAHANG
Tlhaloso ea metsi:
Aluminium sulfate e tsebahala ka thepa ea eona e makatsang e hlakisang metsi. Ha e kenyelletsoa ho metsi a letamo, e etsa hore alunium e be aluninum hydroxide e tlamang likaroloana le litšila tsa bona tse bonolo ka ho isoa ha lintho tse bonolo ka ho itlotsoa habonolo. Sena se fella ka metsi a hlakileng a letshepehi a matlafatsang aesthetics a kaholio a felletseng a letamo.
Puisano ea PH:
Sulfate ea rona ea aluminium e sebetsa e le molaoli oa ph, o thusa ho tsitsisa le ho boloka boemo bo nepahetseng metsing a letamong. PH e nepahetseng e leka-lekanya bakeng sa ho thibela lisebelisoa tsa lebokose, ho netefatsa katleho ea li-shinizers le ho fana ka boiphihlelo bo bonolo ba ho sesa.
Phetoho ea Alkalinity:
Sesebelisoa sena sa sehlahisoa sa ho laola maemo a Alkalinight metsing a letangoeng. Ka ho itekanela Alulinity, Aluminium sulfate e thusa ho thibela maemo a ho feto-fetoha le maemo a PH, tikoloho e tsitsitseng le e leka-lekaneng bakeng sa ba sesa le lisebelisoa tsa letamo.
Lipalesa:
Aluminium sulfate ke moemeli ea ntseng a eketseha haholo, e tsamaisana le kakaretso ea likaroloana tse nyane ho fihlela likhahla tse kholo. Likotsi tsena tse kholo li na le litšila, ho ntlafatsa mahlako a sistimi ea mohala le ho fokotsa mojaro ho pompo ea letangoana.
Likopo
Ho sebelisa aluminium sulfate, latela mehato ena e bonolo:
Qhala ka metsing:
Hlakola palo e khothalletsoang ea aluminium sulfate ka nkhong ea metsi. Tsosa tharollo ea ho netefatsa khefu e felletseng.
Esita le ho tsamaisa:
Tšela ka tharollo e qhibiliha ka mokhoa o qhibilihileng ka ho pholletsa le letamong le le leng, e le ka mokhoa o tšoanang ka moo ho ka khonehang.
Fittara:
Matha sistimi ea litebele bakeng sa nako e lekaneng ea ho lumella aluminium sulfate e hokahaneng le litlolo le ho li fihlela.
Ho lekola khafetsa:
Kamehla o hlokomela boemo ba Alkalinity ho netefatsa hore ba lula ba le har'a mofuta o khothalletsoang. Fetolela ha ho hlokahala.
Tlhokomeliso:
Ho bohlokoa ho latela litekanyetso tse khothalelitsoeng le litaelo tsa kopo tse fanoeng ho label ea sehlahisoa. Ho feta tekano ho ka lebisa litlamorao tse sa rateheng, 'me ho phalla ho ka fella ka kalafo ea metsi a sa sebetseng hantle.
Sulfate ea rona ea aluminium ke tharollo e tšepahalang ea ho boloka metsi a letangoeng a letangoeng. Ka melemo ea eona e mengata, ho kenyelletsa le ho hlakisoa ke metsi, ho hlophisoa ha Masphalinight, ho phatloha ha phosphate, le bona ka pono li bolotsana. Tšepa aluminium ea rona ea alumium-sehlopha sa sulfate ea ho boloka metsi a hao a letamo le ho mema.
