Cryolite Synthetic no ka hoolei ana | 15096-52-3
Hōʻike huahana:
Hoʻohana ʻia ka cryolite i ka hoʻolei ʻana i kēia manawa. Hoʻohana nui ʻia ka cryolite i ka hana ʻana i ka hao ductile. ʻO nā kuhikuhi nui e like me kēia:
1. E kāpīpī i ka hao i hoʻoheheʻe ʻia, ʻo ka nui he 0.1% -0.3%, a ʻo kāna kuleana e wehe i ka slag a uhi i nā mea āpau.
Hiki i ka Cryolite ke hoʻoheheʻe i ka slag i hiki ke hōʻiliʻili a wehe ʻia.
Hoʻoheheʻe ʻia ka cryolite i ka wā i wela ai (ʻoi aku ma mua o 1011 ℃) e hana i ke kinoea fluoride alumini (AlF3), hiki ke pale i ka ʻili o ka hao i hoʻoheheʻe ʻia a pale i ka oxidation, akā he mea pōʻino kēia kinoea i ke kino o ke kanaka.
2. Ua uhi ʻia ka ʻili o ka lua wai me ka pauka cryolite, kahi e pale pono ai i ka hiki ʻana o nā pores subcutaneous.
Ma hope o ka ninini ʻana, aia kahi papa hoʻoheheʻe cryolite ma luna o ka mea hoʻoheheʻe metala, hiki iā ia ke hoʻoheheʻe i ka hoʻohaʻahaʻa ʻana o ka mahu wai ma ke kikowaena, kahi e hoʻemi ai i ke kumu i koi ʻia no ka hydrogen evolution i loko o ka pā hao i hoʻoheheʻe ʻia e hana i ke kumu o ka ʻōpū;
ʻO ke kinoea fluoride aluminika i hana ʻia e ka decomposition o ka cryolite haʻahaʻa hiki ke pale i ka papa ferroelectric interfacial mai nā hopena kemika like ʻole ma ka papa interfacial, e pale ana i ka papa ferromagnetic interfacial mai ka hoʻomoʻa ʻana i ka hydrogen.
Cryolite physical waiwai: sodium hexafluoroaluminate, molecular formula Na3AlF6, molecular kaumaha he 209.94, no ka paʻakikī, he mea hiki ole ke paʻakai pālua, Na + ion a me [AlF6] 3- ion ma hope o ka hemo ana.
ʻAʻole ʻona, keʻokeʻo, keʻokeʻo, ʻeleʻele melemele a i ʻole nā mea ʻeleʻele ma muli o nā haumia, ʻo kona helu hoʻoheheʻe ʻana he 1025 ℃, nui ka nui o ka 0.6 ~ 1.0g / L, ʻoiaʻiʻo ʻo 2.95 ~ 3.05g / cm3, ʻo ka hana wela he 225KJ ,
ʻO ka umekaumaha kikoʻī ʻo 2.75 ~ 3.00g / cm3, ʻo ka wela o ka hui ʻana he 107KJ, nā kala kala monoclinic kala ʻole, ʻaneʻane cubic ka helehelena, a ʻaʻohe kala o ka huahana maʻemaʻe. He keʻokeʻo keʻokeʻo, melemele māmā, ʻulaʻula māmā, a ʻeleʻele hoʻi ma muli o nā haumia.
He poloka paʻa pinepine ʻaʻole kūpono ia no ka mahele. Alohilohi a pulu kona ʻōlinolino, keʻokeʻo kona mau kaha, a he aniani aniani kona.
E hoʻomohu maʻalahi i ka wai a me ka makū, hiki ke hoʻoheheʻe iki ʻia i ka wai, he ʻawaka ka hoʻonā wai, a hoʻokuʻu ia i ke kinoea HF ʻawaʻawa i ka wā e hui ai i ka sulfuric acid.
Hoʻohana maʻamau e like me ka flux no ka hoʻoheheʻe aluminika, nā pesticides no nā mea kanu, ma ke ʻano he flux no nā aniani seramika, a ma ke ʻano he opalescent agent; Hoʻohana ʻia ia e hana i ke aniani opalescent, a hiki ke hoʻohana ʻia ma ke ʻano he electrolyte no ka hana ʻana i nā alumini alumini, nā hao hao, a me nā kila paila, a no ka wili ʻana i nā huila, nā mea hana etc.
Pākē: 25KG / BAG a i ʻole e like me kāu noi.
E mālama: E kūʻai ma kahi wahi maloʻo.
Mana Hoʻokō: International Standard.
