sodium formaldehyde sulfoxylate / Formaldehyde hydrosulfiterium bisulfoxylate
Izimpawu zesiNgisi
udayi mhlophe
impahla yamakhemikhali
Ifomula yamakhemikhali: Isisindo se-CH2 (OH2 (OH2 (OH2 (OH2 (AH2.10 CAS: 149-44-0einec: 205-739-4 Iphuzu elibiyelwe: I-646.4 ℃ Iphuzu le-Flash: 223.8 ℃
Ukwethulwa komkhiqizo nezici
I-COLCOLE BLOCK, eyaziwa nangokuthi i-diao white powder, ku-formalin ihlanganiswe nokuvuselelwa kwe-sodium bisulfite, igama lamakhemikhali le-CH2 (oh) Soo2na, i-white block noma iphunga eliphansi; Incibilika emanzini, incibilika kancane ngotshwala. Kuzinzile emazingeni okushisa asekamelweni, futhi kunokunciphisa okuqinile kanye nomphumela wokufafaza okushisa okuphezulu. Endabeni yokuwohloka kwe-acid, kukhishwa i-hydrogen sulfide, zizinze lapho i-pH> 3, ezinzile ziye ku-alkali. Imvamisa isetshenziswa embonini yokuphrinta nokudaya njenge-ejenti yokukhipha kanye nokunciphisa i-ejenti ukukhiqiza udayi we-indigo, ukunciphisa udayi nokunye. Kepha ngeke isetshenziswe njengokudla okuthe xaxa kokudla, okuvunyelwe ngokuqinile nokungena.
umsebenzi
Kuyi-ejenti yokufaka okuthe xaxa yokusetshenziswa kwezimboni ngenxa yokuncishiswa kwayo okuqinile ekushiseni okuphezulu. Embonini yokuphrinta nokudaya kusetshenziswa njenge-ejenti yokukhishwa kanye nokunciphisa i-ejenti, ukukhiqizwa udayi we-indigo; Futhi esetshenziswa njengemboni yerabha i-styrere burrene burnee rubber polymerization; Izithombe zezithombe zezithombe zezithombe ze-auxiliar; I-ejenti yokufaka e-bleaching yokusetshenziswa kwansuku zonke kanye nemboni yemithi.
iphakheji nokuhamba
B. Lo mkhiqizo ungasetshenziswa, 25kg, emiphongolweni.
C. Isitolo esivalwe ngendawo epholile, eyomile futhi enomoya ongena ngaphakathi. Iziqukathi kufanele zivalwe ngokuqinile ngemuva kokusetshenziswa ngakunye ngaphambi kokusebenzisa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuhamba ukuvikela umswakama, i-alkali ne-acid, imvula nokunye ukungcola okukuxubana.
