umsebenzi
isetshenziswa emkhakheni wezimayini njenge-inhibitor, umenzeli welapha, ukususa i-ejenti
Isetshenziswa ku-Synthetic Organic Phakathi kanye nokulungiswa kwezithasiselo zedayi se-sulfur.
Isetshenziswa emkhakheni wezindwangu njenge-bleaching, njenge-deselfururing kanye ne-ejenti ye-dechloriniting
isetshenziswe ePulp nephepha embonini yamaphepha.
isetshenziswa ekwelashweni kwamanzi njenge-ejenti ye-scavenger ye-oxygen.
Okunye okusetshenzisiwe
Emboni yezithombe ukuvikela izixazululo zonjiniyela kusuka ku-oxidation.
Isetshenziselwa ukukhiqizwa kwamakhemikhali enjoloba namanye amakhemikhali amakhemikhali.
♦ Isebenzisa kwezinye izinhlelo zokusebenza ifaka ukugcwaliswa kwe-ore, ukuvuselelwa kwamafutha, ukulondolozwa kokudla, ukwenza ukudla, ukwenza amadayi kanye nokuhlanza.
Ukuphatha nokugcina
A.Precautions wokuphatha
I-1.Handing yenziwa endaweni enomoya omuhle.
I-2.wear imishini yokuvikela efanelekile.
Ukuxhumana kwe-3.avoid nesikhumba namehlo.
4.Kuka kude nokushisa / spark / ukuvula amalangabi / izindawo ezishisayo.
5.Thatha izindlela zokuphepha eziphikisana nokukhishwa kwe-tulic.
B.Precaunts for Storage
1.Keep iziqukathi zivaliwe ngokuqinile.
2.Keep Iziqukathi endaweni eyomile, epholile futhi enomoya omuhle.
3.Kepha kude nokushisa / Spark / ovulekile amalangabi / izindawo ezishisayo.
4. Gcina kude nezinto ezingahambisani neziqukathi zokudla.
Izakhiwo zenyama nezamakhemikhali ze-sodium hydrosulphide (nahs)
1. Izakhiwo ezibonakalayo
Ukubukeka: I-Sodium Hydrosulfide imvamisa i-White noma i-Yellow Yellow Crystalline powder. Kungahle kube yi-colorless to ophuzi, e-deliquescent crystal ngephunga le-hydrogen sulfide.
Iphoyinti elincibilikayo: Iphuzu lokuncibilika le-anhydrous sodium hydrosulfide lingu-350 ° C; Iphuzu lokuncibilika le-hydrate liphansi, ngo-52-54 ° C. Kodwa-ke, eminye imininingwane ikhombisa ukuthi iphuzu lokuncibilika le-sodium hydrosulfide lingu-55 ° C.
Ubuningi: Ubukhulu beSodium Hydrosulfide ngu-1.79 g / cm³, noma ngo-1790 kg / m³.
I-Solubinity: I-Sodium Hydrosulfide iyancibilika kalula emanzini notshwala, nesisombululo salo esinamanzi yi-alkali. Ngokusho kweminye imininingwane, i-solubility ye-sodium hydrosulfide emanzini ingu-620g / l ku-20 ° C.
2. Izakhiwo zamakhemikhali
I-Acidity ne-Alkalinity: Isixazululo esinamanzi se-sodium hydrosulfide yi-alkaline.
Ukuphendula nge-acid: I-Sodium Hydrosulfide ikhipha i-hydrogen sulfide gesi lapho ihlangana ne-acid. I-equation yokuphendula yile: nahs + h + → H2S ↑ + na +.
Ukusabela ngesibabule: I-Sodium Hydrosulfide ingasabela ngesibabule ukwenza ama-polysulfides, ukulingana okusabela yile: 2 naws + 4s → 1
Ukuncishiswa: I-Sodium Hydrosulfide iyi-ejenti evame ukusetshenziswa esetshenziselwe ukusabela kabusha ngama-oxidants amaningi.
3. Ezinye izakhiwo
Ukuqina: I-Sodium Hydrosulfide iyingxenye ezinzile, kepha i-hygroscopic. Ngasikhathi sinye, futhi kuqinile okuqinile futhi kungakhanya emoyeni.
Ubuthi: I-Sodium Hydrosulfide inobuthi ngezinga elithile futhi iyingozi emzimbeni womuntu kanye nemvelo. Ngakho-ke, ukunakwa okukhethekile kufanele kukhokhwe kuvikelwe ukuphepha ngesikhathi sokusetshenziswa nokugcina.
Njengamanje, inkampani ikhulisa ngokuqinile izimakethe zakwa-phesheya kanye nokuhlelwa komhlaba wonke.
Eminyakeni emithathu ezayo, sizibophezele ekubeni ngenye yamabhizinisi aphezulu okuthumela kwelinye izwe embonini yamakhemikhali ahamba phambili eChina, asebenzela umhlaba ngemikhiqizo esezingeni eliphakeme futhi athole isimo se-Win-Win namakhasimende amaningi.
Ukufaka ndawonye
Thayipha eyodwa: Izikhwama ezingama-25 kg ze-KG (Gwema imvula, ukuvezwa kwelanga nokulangazelela.)
Thayipha izikhwama ezimbili: 900/1000 kg
ethwebula
Ukuhamba kwesitimela
Isitifiketi senkampani
