Helu CAS 7446-9-5 Mea Hana Sulfur Dioxide. Kumukuai o Sulfur Dioxide

ʻO ka Sulfur dioxide (SO₂) he kinoea ʻawaʻawa me ka ʻala ʻoi loa. He huahana ia o nā kaʻina hana ʻenehana like ʻole a hana maoli ʻia ma o ka hana lua pele. Eia kekahi mau hiʻohiʻona nui o ka sulfur dioxide:

Nā waiwai kemika:
Ke Kumu Molekala: SO₂
Kaumaha Molekala: Ma kahi o 64.06 g/mol
Helu CAS: 7446-09-5
Nā waiwai kino:
Ma ka lumi wela a me ke kaomi, ʻike ʻia ia he kinoea kala ʻole.
ʻOi aku ke kaumaha ma mua o ka ea, me ka mānoanoa ma kahi o 2.9 kg/m³ ma nā kūlana maʻamau.
ʻO ka Sulfur dioxide he wahi paila o -10.0°C (14°F) a me kahi helu hehee o -72.7°C (-98.9°F).
ʻona:
ʻO ka sulfur dioxide he mea hoʻonāukiuki hanu a hiki ke hōʻeha i nā pilikia olakino koʻikoʻi ke inhaled.
Hiki ke alakaʻi i nā ʻano kiʻekiʻe i ka pōʻino o ka māmā, bronchitis, a i ʻole ka make.
Hiki iā ia ke hoʻonāukiuki i nā maka a me nā mucous membranes.
Ka hopena o ke kaiapuni:
Hāʻawi ia i ka hoʻokumu ʻana i ka ua ʻakika ke hana ʻia me ka mahu wai i ka lewa.
Hiki i ka sulfur dioxide ke alakaʻi i ka hoʻokumu ʻana i nā mea ʻāpana i hiki ke loaʻa nā hopena maikaʻi ʻole i ke olakino kanaka a me ka ʻike.
Hoʻohana:
I ka ʻoihana meaʻai, hoʻohana ʻia ka sulfur dioxide ma ke ʻano he preservative e pale i ka oxidation a me ka ulu microbial.
Hoʻohana ʻia ia i ka hana ʻana o ka sulfuric acid.
He kuleana ko ia i ka pulp a me ka ʻoihana pepa no ka hoʻomaʻemaʻe ʻana i ka pulp lāʻau.
Hoʻohana ʻia ka sulfur dioxide i ke kaʻina hana waina e pale ai i ka pala.
E pili ana i nā mea hoʻolako, lawe pinepine nā mea hoʻolaha kemika nui i ka sulfur dioxide, a hiki ke loaʻa i nā ʻano like ʻole e like me nā pahu kinoea paʻa a i ʻole nā ​​ipu wai. SDS) i hāʻawi ʻia e ka mea hoʻolako. He mea koʻikoʻi ka mālama ʻana a me ka mālama ʻana ma muli o kona ʻano pōʻino. Inā makemake ʻoe i ka ʻike kikoʻī a i ʻole nā ​​kikoʻī pili o kahi mea hoʻolako, pono wau e ʻike i kou wahi a me ka nui o kāu mau koi. E ʻoluʻolu e haʻi mai iaʻu inā makemake ʻoe i ke kōkua hou aku.
