DESCRIPTION
I-Sodium Metabisulfite iyi- powder emhlophe ecwebezelayo esetshenziswa kabanzi njengesilondolozi , i-antioxidant, isibulala-magciwane, kanye ne-ejenti yokunciphisa . Ivamise ukusetshenziswa ekucubunguleni ukudla neziphuzo, ekwelapheni amanzi, kwezemithi, kwezendwangu, ezimayini, nasezimbonini ze-pulp & paper..
Ngenxa yezakhiwo zayo eziqinile zokunciphisa kanye nokukhululwa kwesulfure dioxide (SO₂) ezixazululweni ezinamanzi , i-sodium metabisulfite iyikhemikhali ebalulekile yokulawula i-oxidation, inhibition microbial, kanye ne-dechlorination..

I-Sodium Metabisulfite ikhiqizwa ngokumuncwa okulawulwayo kwesulfure dioxide ku-sodium carbonate noma i-sodium hydroxide solutions , kulandelwe icrystallization nokomisa..
Ukulawulwa kwekhwalithi kuhlanganisa:
I-Assay kanye nokuhlaziywa kokuqukethwe kwe-SO₂
Ukuhlolwa komswakama nokungcola
Ukulandeleka kwenqwaba nokuqinisekiswa kokuvumelana
Amabanga atholakalayo:
Ibanga Lokudla (E223)
Ibanga lezimboni
IBanga Lezemithi
I-Preservative kanye ne-antioxidant (E223)
Ivimbela ukunsundu kwe-enzymatic ezithelweni nasemifino
Isetshenziselwa iwayini, ubhiya, ijusi, kanye nokucubungula ukudla okomisiwe
I-ejenti ye-Dechlorination
Ukususwa kwe-chlorine esele ne-chloramine
I-oxygen scavenger ezinhlelweni zamanzi zezimboni
I-Antioxidant kanye ne-stabilizer ekwakhiweni
Imaphakathi ekukhiqizeni i-API
I-Depressant kuzinqubo ze-flotation
Igolide ne-copper ore processing
I-ejenti yokuhlanza kanye ne-ejenti yokunciphisa
Ukulungiswa kombala nokucutshungulwa kwe-pulp
Izinketho zokupakisha:
Isikhwama esilukiwe esingu-25 kg esine-PE liner
1,000 kg jumbo bag (FIBC)
Ukupakisha okwenziwe ngezifiso kuyatholakala
Imibandela Yesitoreji:
Gcina ezindaweni ezipholile, ezomile nezinomoya omuhle
Vikela emanzini, ekushiseni, nasekukhanyeni kwelanga
Gwema ukuthintana nama-acids (ikhipha i-SO₂ gas)
Impilo Yeshelufu: Izinyanga eziyi-12 ngaphansi kwezimo ezifanele zokugcina
Ikhipha i-sulphur dioxide lapho ithinta ama-asidi noma umswakama
Gwema ukuhogela uthuli
Sebenzisa amagilavu okuvikela, imaski, nokuvikela amehlo
Bheka ku- SDS/MSDS ukuze uthole imiyalelo enemininingwane yokuphepha
Amadokhumenti atholakala uma ecelwa:
I-COA (Isitifiketi Sokuhlaziya)
I-SDS / MSDS
Ukuthobela izinga lokudla (E223)
REACH, ISO, kanye nemibhalo yokuthekelisa
✔ Okuqukethwe okuphezulu kwe-SO₂ nekhwalithi ezinzile
✔ Itholakala ekudleni, ekhemisi, nakumamaki ezimboni
✔ Ukulawulwa kwekhwalithi okuqinile nokuvumelana kwenqwaba
✔ Amanani ancintisanayo kanye nokunikezwa komhlaba okuthembekile
✔ Ukusekelwa kochwepheshe kwezobuchwepheshe nokulawula
Q1: Isetshenziselwani i-Sodium Metabisulfite?
Isetshenziswa njenge-preservative, i-antioxidant, i-ejenti yokunciphisa, kanye namakhemikhali e-dechlorination kuzo zonke izimboni eziningi.
Q2: Ingabe ukudla kwe-Sodium Metabisulfite kuphephile?
I-sodium metabisulfite yezinga lokudla (E223) ivunyelwe ukusetshenziswa ngaphakathi kwemikhawulo elawulwayo.
Q3: Ingabe ikhulula i-sulphur dioxide?
Yebo, ikhipha i-SO₂ lapho incibilika emanzini noma ivezwe kuma-asidi.
Q4: Kufanele igcinwe kanjani?
Gcina ezitsheni ezingangeni moya ngaphansi kwezimo ezomile nezipholile ukuze ugweme ukubola.
