He pauka kristal keʻokeʻo a melemele paha ka sodium metabisulfite a he kristal liʻiliʻi paha me kahi ʻala SO2 ikaika. He waikawa kona hopena wai a hoʻokuʻu i ka SO2 ke hoʻopili ʻia me nā waikawa ikaika, e hana ana i nā paʻakai like. Inā waiho ʻia i ka lewa no ka manawa lōʻihi, e oxidize ia i Na2S2O6, no laila ʻaʻole hiki ke mālama ʻia kēia huahana no ka manawa lōʻihi.
Hoʻohana
Hoʻohana ʻia ma ke ʻano he mau mea mālama, nā mea hoʻokeʻokeʻo, a me nā mea hoʻokuʻu i ka hana ʻana i ka meaʻai. Hoʻohana ʻia ka sodium metabisulfite i nā ʻoihana e like me ka paʻi ʻana a me ka hoʻoluʻu ʻana, ka synthesis organik, ka paʻi ʻana, ka hana ʻili, nā lāʻau lapaʻau, a pēlā aku; Hoʻohana ʻia ka sodium metabisulfite i nā ʻoihana kemika a me nā lāʻau lapaʻau no ka hana ʻana i ka pauka ʻinikua, sulfamethoxazole metamaterial, caprolactam, a no ka hoʻomaʻemaʻe ʻana o ka chloroform, phenylpropanoid sulfone, a me benzaldehyde. Hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa i ka ʻoihana kiʻi. Hoʻohana ʻia ka ʻoihana mea ʻala e hana i ka vanillin. Hoʻohana ʻia ma ke ʻano he mea mālama i ka ʻoihana hana pia, kahi coagulant rubber, a me kahi mea dechlorination no nā lole pulupulu i hoʻokeʻokeʻo ʻia. Nā mea waena organik, nā dyes, ka ʻili i hoʻohana ʻia ma ke ʻano he mau mea hoʻemi, hoʻohana ʻia i ka ʻoihana electroplating, ka mālama ʻana i ka wai hoʻoneoneo i nā kahua aila, a hoʻohana ʻia ma ke ʻano he mau mea hana mineral i nā mines.
ʻŌpala a me ka Hoʻouna ʻana
25KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
No nā waiwai maʻamau a hiki ke hāʻawi ma ke kai a me ka lewa
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
