Amagama afanayo kwisiNgesi
ukudaya mhlophe
ipropati yeekhemikhali
Ifomyula yekhemikhali: CH2(OH)SO2Na Ubunzima bemolekyuli: 118.10 CAS: 149-44-0EinECs: 205-739-4 Iqondo lokunyibilika: 64 ukuya kwi-68 ℃ Iqondo lokubila: 446.4 ℃ Iqondo lokutsha: 223.8 ℃
Intshayelelo yemveliso kunye neempawu zayo
I-Condole block, eyaziwa ngokuba yi-diao white powder, ukuya kwi-formalin edityaniswe ne-sodium bisulfite rereduction, igama lekhemikhali le-formaldehyde sodium bisulfite, ifomula yekhemikhali ye-CH2(OH)SO2Na, ibhloko emhlophe okanye i-crystalline powder, ayinavumba okanye ivumba elincinci le-leek; Inyibilika emanzini, inyibilika kancinci kwi-alcohol. Izinzile kubushushu begumbi, kwaye ine-reducibility enamandla kunye ne-bleaching effect kubushushu obuphezulu. Kwimeko yokubola kwe-asidi, i-hydrogen sulfide iyakhutshwa, izinzile xa i-PH > 3, izinzile ukuya kwi-alkali. Ihlala isetyenziswa kushishino lokuprinta nokudaya njenge-ejenti yokukhupha kunye ne-ejenti yokunciphisa ukuvelisa idayi ye-indigo, idayi yokunciphisa njl. Kodwa ayifanele isetyenziswe njengesongezelelo se-bleaching yokutya, akuvumelekanga ukungena.
sebenzisa
Yiarhente yokufunxa isetyenziselwa imboni ngenxa yokuba iyakwazi ukuncitshiswa kakhulu xa kushushu kakhulu. Kwishishini lokuprinta nokudaya, isetyenziswa njengearhente yokukhupha kunye nearhente yokunciphisa, ukuvelisa idayi ye-indigo; Ikwasetyenziswa njengeshishini lerabha i-styrene butadiene rubber polymerization activator; Izixhobo zokuthatha iifoto ezithambileyo; Iarhente yokufunxa isetyenziselwa imihla ngemihla kunye neshishini lamayeza.
iphakheji kunye nothutho
B. Le mveliso ingasetyenziswa, 25KG, kwiibhareli.
C. Gcina ivalwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi. Izikhongozeli mazivalwe kakuhle emva kokusetyenziswa ngakunye ngaphambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthuthwa ukuze kuthintelwe ukufuma, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ukuba zingaxubeki.
