Lefatše - Premier Sodium Sulfite: Khemik'hale ea Bohlokoa bakeng sa Litšebeliso tse Fapaneng tsa Liindasteri
Masimo a Maholo a Kopo
Indastering ea pampiri, sodium sulfite e phetha karolo ea bohlokoa. E sebelisoa ts'ebetsong ea pulping ho qhaqha lignin, polymer e rarahaneng e tlamang likhoele tsa cellulose ka lehong. Ka ho sebetsana le lignin, sodium sulfite e thusa ho e qhala, e arola likhoele tsa cellulose le ho li etsa hore li fumanehe bakeng sa ho etsa pampiri. Sena se fella ka pulp ea boleng bo holimo e nang le matla le khanya e ntlafetseng. Bahlahisi ba pampiri ba itšetleha ka sodium sulfite ea rona ho hlahisa lihlahisoa tse fapaneng tsa pampiri, ho tloha khatisong ea litaba ho ea lipampiring tsa khatiso tse phahameng, ka ts'ebetso le ponahalo e ntlafalitsoeng.
Indasteri ea masela e boetse e rua molemo o moholo ho tsoa ho Global - Premier Sodium Sulfite ea rona. E sebelisoa e le moemeli oa ho fokotsa ho daea le ho qeta masela. Ha ho dauoa, sodium sulfite e thusa ho fetola lidae tse itseng hore e be libopeho tsa tsona tse qhibilihang, e leng se li lumellang ho kenella ka har'a likhoele tsa masela ka katleho e kholo. Sena se lebisa mebala e khanyang le e tšoarellang nako e telele. Ho feta moo, e ka sebelisoa ho tlosa dae e feteletseng le lintho tse eketsang oksijene leselang, ho ntlafatsa boleng ba sehlahisoa se felileng. Lifeme tsa masela li sebelisa sodium sulfite ea rona ho etsa masela a boleng bo holimo a fihlelang litlhoko tsa mebaraka ea feshene le mekhabiso ea lehae.
Indastering ea lijo, sodium sulfite e sebetsa e le sesebelisoa sa ho boloka le ho thibela ho bola ha lintho tse phelang. E thusa ho thibela ho bola ha likarolo tsa lijo, tse kang mafura le oli, tse ka lebisang ho rancidence le ho senyeha. E boetse e thibela kholo ea likokoana-hloko, e eketsa nako ea ho phela ha lihlahisoa tsa lijo. Mohlala, litholoana le meroho e omisitsoeng, sodium sulfite e thusa ho boloka 'mala oa tsona, tatso le boleng ba phepo. Bahlahisi ba lijo ba itšetleha ka sodium sulfite ea rona ho netefatsa polokeho le boleng ba lihlahisoa tsa bona, ha ba ntse ba fihlela melao e thata ea polokeho ea lijo.
Indastering ea kalafo ea metsi, sodium sulfite e sebelisoa e le sesebelisoa sa ho tlosa oksijene. Oksijene e qhibilihisitsoeng ka metsing e ka baka mafome liphaepheng, liboiler le lisebelisoa tse ling tsa indasteri. Sodium sulfite e arabela le oksijene ho etsa sodium sulfate, e tlosa oksijene le ho thibela mafome. Litsi tsa kalafo ea metsi le libaka tsa indasteri li sebelisa sodium sulfite ea rona ho sireletsa lisebelisoa tsa tsona, ho fokotsa litšenyehelo tsa tlhokomelo, le ho netefatsa ts'ebetso e sebetsang ea litsamaiso tsa tsona.
