i-sodium formaldehyde sulfoxylate/formaldehyde hydrosulfiteI-sodium bisulfoxylate
Amagama afanayo ngesiNgisi
ukudaya mhlophe
impahla yamakhemikhali
Ifomula yamakhemikhali: CH2(OH)SO2Na Isisindo sama-molecule: 118.10 CAS: 149-44-0EinECs: 205-739-4 Iphuzu lokuncibilika: 64 kuya ku-68 ℃ Iphuzu lokubila: 446.4 ℃ Iphuzu lokuphazima: 223.8 ℃
Isingeniso somkhiqizo kanye nezici
I-Condole block, eyaziwa nangokuthi i-diao white powder, i-formalin ehlanganiswe ne-sodium bisulfite rereduction, igama lekhemikhali le-formaldehyde sodium bisulfite, ifomula yekhemikhali ye-CH2(OH)SO2Na, i-white block noma i-crystalline powder, ayinaphunga noma iphunga elincane le-leek; Incibilika emanzini, incibilika kancane otshwaleni. Izinzile ekushiseni kwegumbi, futhi inomphumela wokunciphisa amandla kanye nokufiphala ekushiseni okuphezulu. Endabeni yokubola kwe-asidi, i-hydrogen sulfide iyakhishwa, izinzile lapho i-PH > 3, izinzile kuya ku-alkali. Ivame ukusetshenziswa embonini yokunyathelisa nokudaya njenge-ejenti yokukhipha kanye ne-ejenti yokunciphisa ukukhiqiza udayi we-indigo, udayi wokunciphisa nokunye. Kodwa akufanele isetshenziswe njengesithasiselo sokufiphala kokudla, okuvinjelwe ngokuphelele ukungena.
sebenzisa
Kuyi-agent yokufiphaza esetshenziswa ezimbonini ngenxa yokuthi iyakwazi ukufiphaza kakhulu ekushiseni okuphezulu. Embonini yokunyathelisa nokudaya, kusetshenziswa njenge-agent yokukhipha kanye ne-agent yokunciphisa, ukukhiqizwa kwedayi ye-indigo; Kusetshenziswa futhi njenge-activator yerabha i-styrene butadiene rubber polymerization activator; Izinto ezithatha izithombe ezithambile; I-agent yokufiphaza esetshenziswa nsuku zonke kanye nemboni yezemithi.
iphakheji kanye nokuthuthwa
B. Lo mkhiqizo ungasetshenziswa, 25KG, emiphongolweni.
C. Gcina kuvaliwe endaweni epholile, eyomile futhi enomoya opholile ngaphakathi. Izitsha kufanele zivalwe kahle ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthuthwa ukuze kuvinjelwe umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
