ʻO ka Sodium Sulphate vs Sodium Sulfite: He aha ka ʻokoʻa?

Ma ka ʻāpana kemika ʻoihana, ʻo ka pololei o ka nomenclature ka mea nui loa. ʻO kahi ʻokoʻa o hoʻokahi leka a i ʻole hoʻokahi ʻātoma oxygen hiki ke hoʻololi loa i ke ʻano molekala o kahi hui, ka ʻikepili pōpilikia, a me ka noi ʻoihana. ʻO kekahi o nā mea maʻamau o ka huikau no nā luna kūʻai, nā mea hoʻonohonoho logistics, a me nā ʻenekinia kaʻina hana ʻōpio e pili ana i ʻelua mau hui inorganic sodium i hoʻohana nui ʻia: Sodium Sulphate (Na₂SO₄)a me Sodium Sulfite (Na₂SO₃).

ʻOiai ke kani like nei ko lākou mau inoa, ʻo ka hoʻouna ʻana iā lākou me ke ʻano like ʻole a i ʻole ka hoʻohana ʻana i ka ʻano hewa i loko o kahi ʻano hana hiki ke hōʻino i nā ʻāpana hana holoʻokoʻa. Hōʻike kēia alakaʻi loea i nā ʻokoʻa kumu o ke ʻano, kemika, a me ka hana ma waena o kēia mau kemika hana ʻelua.

1. ʻAno Kemika a me nā Mokuʻāina Oxidation

ʻO ke kumu o ka ʻokoʻa e waiho wale ana i loko o kā lākou mau ʻano kemika a me ke kūlana oxidation o ka ʻātoma sulfur waena.

ʻO ka sodium sulfate (ʻO ia₂NO laila₄):Ua kākau ʻia hoʻi ʻo Sodium Sulfate, hōʻike kēia hui i kahi ʻātoma sulfur i hoʻopaʻa ʻia i ʻehā mau ʻātoma oxygen. Maanei, aia ka sulfur i kona kūlana oxidation paʻa kiʻekiʻe loa (+6). Ma muli o ka oxidized piha ʻana, paʻa ke kemika o Sodium Sulphate, inert, a ʻaʻole maʻalahi ke komo i nā hopena redox (reduction-oxidation) ma lalo o nā kūlana hana maʻamau.

Sodium Sulfite (ʻO ia₂NO laila₄):Loaʻa i kēia hui hoʻokahi ʻātoma oxygen emi iho, me kahi ʻātoma sulfur i hoʻopaʻa ʻia i ʻekolu mau ʻātoma oxygen. Ma kēia hoʻonohonoho ʻana, noho ka sulfur ma kahi kūlana oxidation haʻahaʻa (+4). No ka mea, ʻaʻole i oxidized piha ʻia, hana ʻo Sodium Sulfite ma ke ʻano he mea ikaika mea hoʻemiHe pilina kūlohelohe ikaika kona no ka oxygen, e loli koke ana i ka sodium sulphate ke hōʻike ʻia i nā wahi oxidizing.

2. Nā Noi ʻOihana: Inert Filler vs. Active Reducer

Ma muli o ke ʻano kū'ē o kā lākou hana kemika, ua ʻokoʻa loa ko lākou kūlana ma nā ʻoihana hana like ʻole.

Nā hoʻohana nui o ka Sodium Sulphate (Na)₂NO laila₄)

Ma muli o kona inertness kemika, ka ikaika ionic kiʻekiʻe, a me ke kūpaʻa wela, hoʻohana nui ʻia ʻo Sodium Sulphate ma ke ʻano he mea kino a mea kūkulu paha ma mua o kahi kemika reactive:

• Nā mea holoi pauka: He mea hoʻopihapiha kūpono loa ia, he mea hoʻopihapiha manuahi a he mea anti-caking, e hoʻoponopono ana i ka viscosity a me ka nui o ka pauka holoi me ka ʻole o ke keakea ʻana i nā surfactants hana.
• Hana ʻana i ke Aniani: Hana ia ma ke ʻano he mea hoʻoheheʻe i loko o ke aniani hoʻoheheʻe ʻia, e kōkua ana i ka wehe ʻana i nā pehu ea microscopic a pale i ka hoʻokumu ʻia ʻana o ka scum i ka wā o ka hoʻoheheʻe ʻana i ka mahana kiʻekiʻe.
• Ka hoʻoluʻu lole: Hoʻohana ʻia ma ke ʻano he mea hoʻohālikelike, hoʻemi ia i nā uku maikaʻi ʻole ma nā lole, e ʻae ana i nā kala e komo like i loko o ka pulupulu a me nā olonā synthetic.

Nā Hoʻohana Nui o ka Sodium Sulfite (Na)₂NO laila₄)

Mahalo i kona hiki ke hoʻokaʻawale a hōʻemi i ka oxygen, hoʻohana ʻia ʻo Sodium Sulfite ma nā wahi e pono ai ke komo ʻana o ka kemika:

• Ka Hoʻōla Wai: Hoʻokomo nui ʻia ia i loko o nā ʻōnaehana wai hānai paila ʻoihana ma ke ʻano he mea hoʻoheheʻe oxygen e pale ai i ka pala kūloko a me ka lua ʻana o nā paipu metala.
• ʻOihana Pulp a me ka Pepa: Hoʻohana ʻia ia i ke kaʻina sulfonation o ka chemimechanical pulping e uhaʻi i nā pilina lignin, e hua mai ana i nā olonā pepa ikaika a ʻoi aku ka mālamalama.
• Mālama ʻana i ka Meaʻai a me ka Waina: Hana ia ma ke ʻano he mea antimicrobial a me antioxidant, e pale ana i ka browning enzymatic a me ka palaho bacteria i nā hua maloʻo a me nā mea inu.

3. Nā Waiwai Kino a me nā ʻOkoʻa o ka Lawelawe ʻana

ʻIke pinepine ʻia nā kemika ʻelua ma ke ʻano he pauka kristal keʻokeʻo a i ʻole nā ​​granules, e hōʻole ai i ka ʻike maka. Eia nō naʻe, ʻokoʻa ko lākou ʻano kino i ka hala ʻana o ka manawa:

• Sodium Sulphate he paʻa loa ia i ka lewa ākea. Loaʻa ia ma ke ʻano anhydrous a i ʻole he decahydrate (paʻakai Glauber).
• Sodium Sulfite he mea maʻalahi ke palaho mālie i ka wā e mālama ai inā pili i ka ea a me ka makū, ʻoiai e omo mālie ana i ka oxygen lewa e hana i ka sodium sulphate. Pono e mālama ʻia i loko o nā pahu ea paʻa me nā kaohi haʻahaʻa haʻahaʻa e mālama ai i kona ikaika kemika.
