Sodium metabisulfite ndi ufa woyera kapena wachikasu wa kristalo kapena kristalo kakang'ono kamene kali ndi fungo lamphamvu la SO2. Madzi ake ndi acidic ndipo amatulutsa SO2 ikakhudzana ndi ma acid amphamvu, zomwe zimapangitsa mchere wofanana. Ngati yasiyidwa mumlengalenga kwa nthawi yayitali, imasungunuka kukhala Na2S2O6, kotero mankhwalawa sangasungidwe kwa nthawi yayitali.
Kagwiritsidwe Ntchito
Amagwiritsidwa ntchito ngati zosungira, zoyeretsera, ndi zotsukira mu kukonza chakudya. Sodium metabisulfite imagwiritsidwa ntchito m'mafakitale monga kusindikiza ndi kupukuta, kupanga zinthu zachilengedwe, kusindikiza, kupanga zikopa, mankhwala, ndi zina zotero; Sodium metabisulfite imagwiritsidwa ntchito m'mafakitale a mankhwala ndi mankhwala popanga ufa wa inshuwaransi, sulfamethoxazole metamaterial, caprolactam, komanso kuyeretsa chloroform, phenylpropanoid sulfone, ndi benzaldehyde. Amagwiritsidwa ntchito ngati chosakaniza chowonjezera mumakampani ojambula zithunzi. Makampani opanga zonunkhira amagwiritsidwa ntchito popanga vanillin. Amagwiritsidwa ntchito ngati chosungira mumakampani opanga mowa, chokometsera rabara, komanso chochotsera chlorination pa nsalu za thonje losweka. Zosakaniza zachilengedwe, utoto, zikopa zomwe zimagwiritsidwa ntchito ngati zochepetsera, zomwe zimagwiritsidwa ntchito mumakampani opanga ma electroplating, kukonza madzi otayira m'minda yamafuta, komanso kugwiritsidwa ntchito ngati zotsukira mchere m'migodi.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
