Lefatše - Sodium Sulfide ea Pele: K'hemik'hale ea Bohlokoa Bakeng sa Libaka tse Fapaneng tsa Liindasteri
Masimo a Maholo a Kopo
Indastering ea pampiri, sodium sulfide ea rona e bapala karolo ea bohlokoa ts'ebetsong ea kraft pulping. E thusa ho qhaqha lignin, polymer e rarahaneng ea tlhaho e tlamang likhoele tsa cellulose ka lehong. Ka ho qhibilihisa lignin, sodium sulfide e nolofalletsa karohano ea cellulose, e leng karolo e ka sehloohong e sebelisoang ho etsa pampiri. Sena se fella ka pulp ea boleng bo holimo e nang le matla le khanya e ntlafetseng. Bahlahisi ba pampiri ba ka hlahisa mefuta e mengata ea lihlahisoa tsa pampiri, ho tloha khatisong ea litaba ho ea lipampiring tsa khatiso tse phahameng, ba sebelisa sodium sulfide ea rona ho ntlafatsa katleho ea tlhahiso ea bona le boleng ba sehlahisoa.
Indasteri ea masela le eona e rua molemo o moholo ho tsoa ho Global - Premier Sodium Sulfide ea rona. E sebelisoa ts'ebetsong ea ho tlosa sulfurization ea ulu. Hangata ulu e na le metsoako e nang le sebabole e ka amang boleng ba eona le ts'ebetso ea eona. Sodium sulfide e arabela le metsoako ena, e tlosa sebabole le ho ntlafatsa bonolo, 'mala le boleng ka kakaretso ba ulu. Ho feta moo, e sebelisoa lits'ebetsong tse ling tsa ho daea ho lokisa tikoloho ea lik'hemik'hale, ho nolofalletsa ho monngoa ha dae ke lesela hamolemo, e leng se lebisang mebala e khanyang le e tšoarellang nako e telele.
Indastering ea merafo, sodium sulfide ke reagent ea bohlokoa. E sebelisoa ts'ebetsong ea ho phaphamala ha li-ore tse itseng tsa tšepe, haholo-holo tse nang le koporo, loto le zinki. Sodium sulfide e ka kenya tšebetsong bokaholimo ba li-ore tsena, e leng se etsang hore li amohelehe haholoanyane ho li-agent tse bokellang tse sebelisoang ho phaphamala. Sena se ntlafatsa haholo bokhoni ba ho arola liminerale tsa bohlokoa ho gangue (lefika la litšila), ho eketsa sekhahla sa ho hlaphoheloa ha li-ore tsa bohlokoa. Likhamphani tsa merafo li itšetleha ka sodium sulfide ea rona ho ntlafatsa ts'ebetso ea tsona ea ho sebetsana le li-ore le ho eketsa phaello ea tsona.
Indastering ea letlalo, sodium sulfide ea rona e sebelisoa ts'ebetsong ea ho tlosa moriri. E thusa ho qhala liprotheine tse moriring le letlalong la liphoofolo, e leng se etsang hore ho be bonolo ho tlosa moriri. Ena ke mohato oa bohlokoa tlhahisong ea letlalo kaha e lokisa letlalo bakeng sa ts'ebetso e tsoelang pele. Ka ho sebelisa sodium sulfide ea rona ea boleng bo holimo, bahlahisi ba letlalo ba ka hlahisa letlalo le nang le bokaholimo bo boreleli le sebopeho se betere, le fihlelang maemo a holimo a 'maraka oa letlalo oa lefats'e.
