Sodium Hydrosulfite 90%, Mākaukau no ka hoʻouna ʻana~

Nā noi:
1. He ākea loa ka hoʻohana ʻana o ka sodium hydrosulfite, ʻo ia hoʻi ka hoʻemi ʻana i ka hoʻoluʻu ʻana, ka hoʻomaʻemaʻe ʻana, ka paʻi ʻana a me ka wehe ʻana i ke kala i ka ʻoihana lole, a me ka hoʻokeʻokeʻo ʻana i ka silika, ka hulu hipa, ka nylon a me nā lole ʻē aʻe. ʻOiai ʻaʻohe metala kaumaha o ka sodium hydrosulfite, ʻālohilohi loa ke kala o ka lole i hoʻokeʻokeʻo ʻia a ʻaʻole maʻalahi e mae.

2. Hiki ke hoʻohana ʻia ka sodium hydrosulfite no ka hoʻokeʻokeʻo ʻana i ka meaʻai, e like me ka gelatin, sucrose, nā hua ʻono, a pēlā aku, a me ke kopa, ka ʻaila holoholona (mea kanu), ka ʻohe, ka hoʻokeʻokeʻo ʻana i ka lepo porcelain.

3. Ma ke kahua o ka synthesis organik, hoʻohana ʻia ka sodium hydrosulfite ma ke ʻano he mea hoʻemi a mea hoʻokeʻokeʻo paha i ka hana ʻana i nā dyes a me nā lāʻau lapaʻau, ʻoi aku hoʻi ma ke ʻano he mea hoʻokeʻokeʻo no ka hana pepa pulp lāʻau.

4. Hiki i ka sodium hydrosulfite ke hoʻemi i nā ion metala kaumaha he nui e like me Pb2+, Bi3+, a pēlā aku i nā metala i ka mālama ʻana i ka wai a me ka kaohi ʻana i ka haumia, a hiki ke hoʻohana ʻia no ka mālama ʻana i ka meaʻai a me nā huaʻai.

Hiki ke lapalapa:He mea lapalapa papa mua ka Sodium dithionite ke pulu e like me nā kūlana aupuni. E pane ikaika ia ke pili me ka wai, e hana ana i nā kinoea lapalapa e like me ka hydrogen sulfide a me ka sulfur dioxide, a e hoʻokuʻu ana i ka nui o ka wela. ʻO ke ʻano o ka hopena: 2Na2S2O4 + 2H2O + O2 = 4NaHSO3, a pane hou nā huahana e hana i ka hydrogen sulfide a me ka sulfur dioxide. Loaʻa iā Sodium dithionite kahi kūlana valence waena o ka sulfur, a he paʻa ʻole kona mau waiwai kemika. Hōʻike ia i nā waiwai hōʻemi ikaika. Ke hālāwai me nā waikawa oxidizing ikaika, e like me ka waikawa sulfuric, ka waikawa perchloric, ka waikawa nitric, ka waikawa phosphoric a me nā waikawa ikaika ʻē aʻe, e hana nā mea ʻelua i kahi hopena redox, a he huhū ka hopena, e hoʻokuʻu ana i ka nui o ka wela a me nā mea ʻawahia. ʻO kāna ʻano hopena: 2Na2S2O4 + 4HCl = 2H2S2O4 + 4NaCl

Ke kuni koke ʻana:ʻO 250℃ ka wela o ke kinoea sodium dithionite. Ma muli o kona wahi hoʻā haʻahaʻa, he mea paʻa lapalapa papa mua ia (ʻo ka wela maʻamau ma lalo o 300℃, a ʻo ka wela o ka wahi hoʻoheheʻe haʻahaʻa ma lalo o 100℃). He maʻalahi loa ke puhi ʻana i ka wā e hōʻike ʻia ai i ka wela, ke ahi, ka hakakā a me ka hopena. He wikiwiki ka wikiwiki o ke ahi a he kiʻekiʻe ka pilikia ahi. ʻO ke kinoea hydrogen sulfide i hana ʻia i ka wā o ke kaʻina hana puhi hiki ke hoʻonui i kahi wahi puhi, e hoʻonui ana i kona pilikia ahi.

Pahū:He mea pauka melemele māmā ka sodium dithionite. He maʻalahi ka hana ʻana i kahi hui pahū i ka lewa. Pahū ka lepo ke hālāwai me kahi kumu ahi. He mea pahū ka hui ʻana o ka sodium dithionite a me ka hapa nui o nā oxidants, e like me chlorates, nitrates, perchlorates, a i ʻole permanganates. ʻOiai i ke alo o ka wai, pahū ia ma hope o ka friction a i ʻole ka hopena iki, ʻoi aku hoʻi ma hope o ka decomposition thermal, hiki i ke kinoea lapalapa i hana ʻia ma hope o ka hopena i ka palena pahū, a laila ʻoi aku ka nui o kona pilikia pahū.
