Litaba

Sebakeng sa ho hloekisa likhoerekhoere le ho hloekisa metsi, Polyaluminium Chloride ke flocculant e sebelisoang haholo ebile e sebetsa haholo. Har'a matšoao a fapaneng a ho lekola boleng le ts'ebetso ea polyaluminium chloride, ha ho pelaelo hore litaba tsa aluminium oxide ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa. E susumetsa haholo katleho, boholo ba ts'ebeliso, le katleho ea litšenyehelo tsa polyaluminium chloride.

E le coagulant ea bohlokoa tšimong ea phekolo ea metsi, ho fumanoa ha polyaluminium chloride (Pac) boleng bo lokela ho etsoa ho potoloha lits'oants'o tsa mantlha, ho kenyeletsoa litaba tsa alumina, letsoai, boleng ba pH le litaba tse sa keneng metsi, jj.

Tšusumetso ea naetrojene e feteletseng tsamaisong ea likhoerekhoere e bonahala haholo ts'ebetsong ea ts'ebetso, ts'ebetso ea likokoana-hloko, le botsitso ba metsi a litšila, joalo ka ha ho hlalositsoe tlhahlobo le likhothaletso tse latelang:

Metal aluminium mokhoa: lebelo la ho arabela le batla le potlakile, 'me palo e itseng ea polyaluminium chloride e ka fumanoa ka nako e khutšoanyane. Ho feta moo, tšepe ea aluminium e fumaneha ka bongata, e fanang ka tiiso e itseng bakeng sa tlhahiso e kholo.

Aluminium chloride (PAC) le polyaluminium ferric chloride (PAFC) ke li-flocculants tse peli tse sebelisoang ka tloaelo, liphapang tse kholo ke tse latelang:

White polyaluminium chloride (eo hape e tsejoang e le spray drying polyaluminum chloride) e sebelisoa haholo libakeng tse ngata ka lebaka la bohloeki bo phahameng le litšobotsi tse tlaase tsa litšila. Tse latelang ke maemo a eona a mantlha a ts'ebeliso le melemo ea tekheniki:

Phapang e kholo lipakeng tsa ferrous sulfate le polymeric ferric sulfate e bonts'oa ka thepa ea lik'hemik'hale, litlamorao tsa kalafo, maemo a ts'ebeliso le ho ikamahanya le maemo tikolohong ka tsela e latelang:

Karolelano ea theko ea 'maraka ea polyaluminium chloride ea boemo ba indasteri ka 2023 e fokotsehile ho tloha ho 2033.75 yuan/ton qalong ea selemo ho ea ho 1777.50 yuan/ton qetellong ea selemo, ka ho theoha ha selemo ka 12.6% le amplitude e phahameng ka ho fetisisa ea 16.41% nakong ea selemo. Ka 2024, ho tla tsoela pele ho ba le mokhoa oa ho theoha, ka theko e kholo ea matla (litaba ≥ 28%) e theohela ho 1781.25 yuan / tonne ka May, ho fokotseha ha 0.70% ho tloha qalong ea selemo. Ka Mmesa 2025, theko ea khale ea feme ea boemo ba indasteri (30% spray) Profinseng ea Henan e tla ba li-yuan tse ka bang 1660/ton, 18.4% e tlase ho feta tlhoro ea 2023.

Ho fumanoa ha litaba tsa polyferric sulfate hangata ho bolela ho lekanya litaba tsa karolo ea eona e kholo - ion ea tšepe. Kaha polyferric sulfate ke motsoako o rarahaneng oa polymer oa inorganic, mekhoa ea eona ea ho lemoha e fapane, e koahelang tlhahlobo ea lik'hemik'hale le tlhahlobo ea lisebelisoa.
