SPECIFICATION

kev siv

siv hauv kev lag luam mining ua inhibitor, curing agent, tshem tus neeg sawv cev

siv nyob rau hauv hluavtaws organic intermediate thiab kev npaj ntawm sulfur dye additives.

Siv hauv kev lag luam textile ua tshuaj dawb, ua desulfurizing thiab ua tus neeg sawv cev dechlorinating

siv hauv kev lag luam pulp thiab ntawv.

siv hauv kev kho dej raws li tus neeg saib xyuas oxygen scavenger.

Lwm yam siv

♦ Hauv kev lag luam yees duab los tiv thaiv cov kev daws teeb meem los ntawm oxidation.
♦ Nws yog siv rau hauv kev tsim cov tshuaj roj hmab thiab lwm cov tshuaj sib txuas.
♦ Nws yog siv nyob rau hauv lwm yam kev siv xws li ore flotation, roj rov qab, zaub mov preservative, ua dyes, thiab detergent.

Sodium hydrosulfide yog cov tshuaj sib xyaw nrog cov mis NaHS. Cov tshuaj no yog cov khoom ntawm ib nrab-neutralization ntawm hydrogen sulfide (H2S) nrog sodium hydroxide. NaHS thiab sodium sulfide yog siv hauv kev lag luam, feem ntau rau cov hom phiaj zoo sib xws. Khoom NaHS tsis muaj xim. Cov khoom muaj ntxhiab H2S vim hydrolysis los ntawm atmospheric noo noo. Nyob rau hauv sib piv nrog sodium sulfide (Na2S), uas yog insoluble nyob rau hauv cov organic solvents, NaHS, yog ib tug 1: 1 electrolyte, yog ntau soluble.

HAIV NEEG THIAB KEV RUAJ NTSEG

Daim Ntawv Ceeb Toom Txog Kev Siv: Hnav cov cuab yeej tiv thaiv kom raug (Saib Tshooj 8). Tsis txhob nqus cov khoom vapors. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag. Siv tsuas yog nyob rau hauv ib qho chaw zoo ventilated. Dilute cov khoom tsuas yog nyob rau hauv lub thawv ntim. Ntxuav kom huv si tom qab tuav.
Daim Ntawv Ceeb Toom Txog Kev Cia: Khaws rau hauv qhov chaw muaj cua zoo. Tsis txhob khaws cov combustibles hauv cheeb tsam ntawm cov hlab ntsha. Cia kom deb ntawm tej qhov chaw uas muaj cua sov los yog nplaim taws. Khaws cov tote thiab cov thawv me me tawm ntawm tshav ntuj ncaj qha ntawm qhov kub nruab nrab [<80 F (27 C)].
