Sodium Thiocyanate: He Kemika ʻOihana Multi-Purpose
Nā Kahua Noi Nui
1. Hana ʻana i ka Fiber Acrylic
He mea nui ka sodium thiocyanate i ka hana ʻana i nā olonā acrylic. I ka wā o ka polymerization o ka acrylonitrile, hana ka sodium thiocyanate ma ke ʻano he solvent, e hāʻawi ana i kahi kūlana paʻa no ka hopena polymerization. Hoʻoheheʻe ia i nā monomers acrylonitrile e hana i kahi ʻōnaehana polymerization like, e hopena ana i nā olonā acrylic kiʻekiʻe. Ua kaulana nā olonā acrylic no ko lākou kūpaʻa kemika maikaʻi loa, ke kūpaʻa ʻana i ka ʻaʻahu, a me ka insulation thermal, e hoʻohana nui ʻia ai i nā lole, nā lole home, a me nā lole ʻoihana.
2. Mea Hoʻohui Kemika Loiloi
He mea nui ka sodium thiocyanate i ka loiloi kemika. Hiki iā ia ke hana i nā hui me nā ion metala e like me nā ion hao, e ʻae ana i ka ʻike a me ka loiloi quantitative o kēia mau ion ma o nā ʻano colorimetric a i ʻole titration. No ka laʻana, i ka loiloi ʻana i nā ion hao i loko o nā laʻana wai, hana ka sodium thiocyanate me nā ion hao e hana i kahi hui koko-ʻulaʻula. Hiki i nā ʻano colorimetric ke hoʻoholo koke a pololei i ka nui o nā ion hao. He ʻano maʻalahi loa kēia ʻano hana a maʻalahi hoʻi e hana, e hoʻohana nui ʻia ana i ka loiloi ʻana i ka maikaʻi o ka wai, ka nānā ʻana i ke kaiapuni, a me ka kaohi ʻana i ka maikaʻi i ka hana ʻoihana.
3. ʻOihana Electroplating
I loko o ka ʻoihana electroplating, hoʻohana pinepine ʻia ka sodium thiocyanate ma ke ʻano he mea hoʻohui i nā hopena electroplating. Hoʻomaikaʻi ia i ka hana o ka papa electroplating, hoʻonui i ke ʻano like a me ka hoʻopili ʻana o ka plating, a hoʻonui i ke kūpaʻa i ka pala a me ke ʻano o nā huahana electroplated. No ka laʻana, i ka electroplating keleawe, ʻo ka hoʻohui ʻana i kahi nui kūpono o ka sodium thiocyanate e pale ai i ka hydrolysis o nā ion keleawe, e hopena ana i kahi papa plating ʻoi aku ka maʻalahi a ʻoi aku ka like me nā pinholes liʻiliʻi a me nā hemahema pitting. Eia kekahi, hiki ke hoʻohana ʻia ka sodium thiocyanate i ka electroplating o nā metala makamae e like me ke gula a me ke kālā, e hoʻomaikaʻi ana i ka luster a me ke kūpaʻa o ka plating.
4. Hana ʻOkanika
Hoʻohana nui ʻia ka sodium thiocyanate i ka synthesis organik. Hiki iā ia ke hana ma ke ʻano he reagent cyanation no ka synthesis o nā hui organik like ʻole. No ka laʻana, i ka synthesis o nā nitriles, hiki i ka sodium thiocyanate ke hana me nā aldehydes a i ʻole ketones e hana i nā nitriles like. Eia kekahi, hiki ke hoʻohana ʻia ka sodium thiocyanate e synthesize i nā hui thiourea, he mea nui ia i nā kahua o nā lāʻau lapaʻau, nā pesticides, a me nā dyes. ʻO ka reactivity a me ke koho ʻana o ka sodium thiocyanate e lilo ia i reagent i hoʻohana pinepine ʻia i ka synthesis organik.
5. Nā noi ʻē aʻe
Hiki ke hoʻohana ʻia ka sodium thiocyanate ma nā ʻano ʻē aʻe. No ka laʻana, ma ka ʻoihana hoʻoluʻu a me ka paʻi ʻana, hiki ke hoʻohana ʻia ma ke ʻano he mea kōkua hoʻoluʻu e hoʻomaikaʻi i ka lawe ʻana a me ka paʻa ʻana o nā mea hoʻoluʻu. Ma ka ʻoihana hana pepa, hiki ke hoʻohana ʻia i nā kaʻina hana hoʻokeʻokeʻo a me ka wehe ʻana i ka inika e hoʻomaikaʻi i ka maikaʻi a me ka hana o ka pepa.
He mea nui ka sodium thiocyanate i ka hana ʻana i nā olonā acrylic. I ka wā o ka polymerization o ka acrylonitrile, hana ka sodium thiocyanate ma ke ʻano he solvent, e hāʻawi ana i kahi kūlana paʻa no ka hopena polymerization. Hoʻoheheʻe ia i nā monomers acrylonitrile e hana i kahi ʻōnaehana polymerization like, e hopena ana i nā olonā acrylic kiʻekiʻe. Ua kaulana nā olonā acrylic no ko lākou kūpaʻa kemika maikaʻi loa, ke kūpaʻa ʻana i ka ʻaʻahu, a me ka insulation thermal, e hoʻohana nui ʻia ai i nā lole, nā lole home, a me nā lole ʻoihana.
2. Mea Hoʻohui Kemika Loiloi
He mea nui ka sodium thiocyanate i ka loiloi kemika. Hiki iā ia ke hana i nā hui me nā ion metala e like me nā ion hao, e ʻae ana i ka ʻike a me ka loiloi quantitative o kēia mau ion ma o nā ʻano colorimetric a i ʻole titration. No ka laʻana, i ka loiloi ʻana i nā ion hao i loko o nā laʻana wai, hana ka sodium thiocyanate me nā ion hao e hana i kahi hui koko-ʻulaʻula. Hiki i nā ʻano colorimetric ke hoʻoholo koke a pololei i ka nui o nā ion hao. He ʻano maʻalahi loa kēia ʻano hana a maʻalahi hoʻi e hana, e hoʻohana nui ʻia ana i ka loiloi ʻana i ka maikaʻi o ka wai, ka nānā ʻana i ke kaiapuni, a me ka kaohi ʻana i ka maikaʻi i ka hana ʻoihana.
3. ʻOihana Electroplating
I loko o ka ʻoihana electroplating, hoʻohana pinepine ʻia ka sodium thiocyanate ma ke ʻano he mea hoʻohui i nā hopena electroplating. Hoʻomaikaʻi ia i ka hana o ka papa electroplating, hoʻonui i ke ʻano like a me ka hoʻopili ʻana o ka plating, a hoʻonui i ke kūpaʻa i ka pala a me ke ʻano o nā huahana electroplated. No ka laʻana, i ka electroplating keleawe, ʻo ka hoʻohui ʻana i kahi nui kūpono o ka sodium thiocyanate e pale ai i ka hydrolysis o nā ion keleawe, e hopena ana i kahi papa plating ʻoi aku ka maʻalahi a ʻoi aku ka like me nā pinholes liʻiliʻi a me nā hemahema pitting. Eia kekahi, hiki ke hoʻohana ʻia ka sodium thiocyanate i ka electroplating o nā metala makamae e like me ke gula a me ke kālā, e hoʻomaikaʻi ana i ka luster a me ke kūpaʻa o ka plating.
4. Hana ʻOkanika
Hoʻohana nui ʻia ka sodium thiocyanate i ka synthesis organik. Hiki iā ia ke hana ma ke ʻano he reagent cyanation no ka synthesis o nā hui organik like ʻole. No ka laʻana, i ka synthesis o nā nitriles, hiki i ka sodium thiocyanate ke hana me nā aldehydes a i ʻole ketones e hana i nā nitriles like. Eia kekahi, hiki ke hoʻohana ʻia ka sodium thiocyanate e synthesize i nā hui thiourea, he mea nui ia i nā kahua o nā lāʻau lapaʻau, nā pesticides, a me nā dyes. ʻO ka reactivity a me ke koho ʻana o ka sodium thiocyanate e lilo ia i reagent i hoʻohana pinepine ʻia i ka synthesis organik.
5. Nā noi ʻē aʻe
Hiki ke hoʻohana ʻia ka sodium thiocyanate ma nā ʻano ʻē aʻe. No ka laʻana, ma ka ʻoihana hoʻoluʻu a me ka paʻi ʻana, hiki ke hoʻohana ʻia ma ke ʻano he mea kōkua hoʻoluʻu e hoʻomaikaʻi i ka lawe ʻana a me ka paʻa ʻana o nā mea hoʻoluʻu. Ma ka ʻoihana hana pepa, hiki ke hoʻohana ʻia i nā kaʻina hana hoʻokeʻokeʻo a me ka wehe ʻana i ka inika e hoʻomaikaʻi i ka maikaʻi a me ka hana o ka pepa.
