He aha ka ʻokoʻa ma waena o ka magnesium oxide a me ka magnesium carbonate?

Magnesium oxideamagnesium carbonateʻokoʻa ko lākou mau waiwai kemika.Magnesium carbonatehe ʻakika nāwaliwali e hoʻoheheʻe ʻia i loko o ka wai a wāwahi i loko o ka magnesium oxide a me ke kalapona kalapona ke hoʻomehana ʻia.ʻO ka Magnesium oxide, ma ka ʻaoʻao ʻē aʻe, he alkaline oxide ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a ʻaʻole hoʻoheheʻe i ka wā i wela ai.

ʻOkoʻa ka ʻoihana noi a me nā ʻano huahana o ka magnesium carbonate a me ka magnesium oxide e like me kēia: ʻOihana noi: Hoʻohana nui ʻia ka magnesium carbonate i nā intermediates pharmaceutical, antacid, desiccant, mea hoʻomalu kala, mea lawe, anti-coagulation agent a pēlā aku;I loko o ka meaʻai ma ke ʻano he mea hoʻohui, ka mea hoʻopaʻi ʻāpana magnesium;I loko o ka ʻoihana kemika maikaʻi no ka hana ʻana i nā reagents kemika;Hoʻohana ʻia e like me ka mea hoʻoikaika a me ka mea hoʻopiha i ka lāʻau;Hiki ke hoʻohana ʻia e like me ka wela wela, ke kiʻekiʻe o ka wela wela i nā mea pale ahi;Uea a me ka uwea manufacturing kaʻina mea nui kemika maka mea, etc. Magnesium oxide ua nui hoʻohana 'ia i loko o ke kila silika, catalyst, pharmaceutical oihana, meaʻai 'oihana, cosmetic maka mea, plastic additives, rubber additives, electrode material, aniani substrate mea a me na kula.Nā hiʻohiʻona huahana: ʻO ka Magnesium carbonate he aniani aniani ʻaʻole waihoʻoluʻu, alkaline, hiki ke hoʻoheheʻe ʻia i ka wai, alkaline iki;ʻO ka Magnesium oxide, ma kekahi ʻaoʻao, he pauka keʻokeʻo, alkaline a hiki ʻole ke hoʻoheheʻe ʻia i ka wai.

Hoʻokaʻawale ʻia ka Magnesium carbonate penei:

Māmā magnesium carbonate: keʻokeʻo a i ʻole ka pauka keʻokeʻo keʻokeʻo, ʻaʻala ʻole, kūpaʻa i ka ea.Ke hoʻomehana ʻia i 700 ° C, decompose ia e hana i ka magnesium oxide, carbon dioxide a me ka wai.Ma ka lumi wela, he paʻakai trihydrate.ʻO ka magnesium carbonate kaumaha: ka pauka keʻokeʻo, ʻono ʻole, hiki ʻole ke hoʻoheheʻe ʻia i ka wai, wela a ʻoi aku ma mua o 150 ℃ decomposition, e hana i ka magnesium oxide a me carbon dioxide.Ma ka lumi wela, he paʻakai hexahydrate.

ʻO ka papa inoa o ka magnesium oxide penei:

ʻO ka magnesium oxide māmā: ʻo ka molecular formula MgO, ke ʻano he keʻokeʻo a i ʻole ka pauka māmā beige, ʻala ʻole a ʻono ʻole.ʻIke ʻia i ka lewa, maʻalahi ke komo i ka wai a me ke kalapona kalapona, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me ka waiʻona, a hiki ke hoʻoheheʻe ʻia i nā waikawa dilute.ʻO ka magnesium oxide ikaika: hoʻohana lohi, hoʻohana ʻia no ka hoʻopiha piha ʻana o ka neoprene, hoʻoikaika a ma ke ʻano he catalyst.ʻO ka magnesium oxide kaumaha: Māmā MgO, ke ʻano o ka pauka keʻokeʻo, ʻaʻala ʻole, hiki ʻole ke hoʻoheheʻe ʻia i ka wai.Ke hoʻomehana ʻia a ʻoi aku ma mua o 1500 ℃, lilo ia i mea make i ka magnesium oxide (magnesia) a i ʻole ka magnesium oxide sintered.
