Kev taw qhia txog khoom thiab nta
Condole block, tseem hu ua diao hmoov dawb, rau formalin ua ke nrog sodium bisulfite rereduction, lub npe tshuaj rau formaldehyde sodium bisulfite, cov mis tshuaj rau CH2 (OH) SO2Na, thaiv dawb lossis hmoov crystalline, tsis muaj ntxhiab tsw lossis me ntsis leek tsw; Yaj hauv dej, yaj me ntsis hauv cawv. Nws ruaj khov ntawm chav tsev kub, thiab muaj zog txo qis thiab ua kom dawb ntawm qhov kub siab. Hauv qhov xwm txheej ntawm acid decomposition, hydrogen sulfide raug tso tawm, ruaj khov thaum PH > 3, ruaj khov rau alkali. Nws feem ntau siv hauv kev luam ntawv thiab dyeing ua tus neeg sawv cev rho tawm thiab txo tus neeg sawv cev los tsim cov xim indigo, txo cov xim thiab lwm yam. Tab sis yuav tsum tsis txhob siv ua cov khoom noj khoom haus bleaching, txwv tsis pub nkag.
siv
Nws yog ib tug neeg sawv cev bleaching rau kev siv hauv kev lag luam vim nws muaj zog reducibility ntawm qhov kub siab. Hauv kev lag luam luam ntawv thiab dyeing siv ua tus neeg sawv cev extraction thiab txo tus neeg sawv cev, kev tsim cov xim indigo; Kuj siv ua kev lag luam roj hmab styrene butadiene roj hmab polymerization activator; Photosensitive photographic cov ntaub ntawv theem auxiliaries; Bleaching tus neeg sawv cev rau kev siv txhua hnub thiab kev lag luam tshuaj.
pob khoom thiab kev thauj mus los
B. Cov khoom no siv tau, 25KG, hauv cov thoob.
C. Khaws cia rau hauv qhov chaw txias, qhuav thiab muaj cua nkag hauv tsev. Yuav tsum kaw cov thawv kom nruj tom qab siv txhua zaus ua ntej siv.
D. Cov khoom no yuav tsum tau kaw zoo thaum lub sijhawm thauj mus los kom tiv thaiv cov dej noo, alkali thiab acid muaj zog, nag thiab lwm yam tsis huv los ntawm kev sib tov.
