Wehewehena a me nā hiʻohiʻona

Wehewehe: Hoʻohana ʻo WNX i ka ʻenehana hana hana automated holomua a hoʻohana i nā mea maka kiʻekiʻe e hana i nā mea kiʻekiʻeLanthanum Sulfate Hydrare.

Nā Hiʻohiʻona Koʻikoʻi:

Maʻemaʻe Kiʻekiʻe:Lanthanum Sulfate Hydrare ʻaʻohe mea haumia mai nā mea honua laha ʻole (e like me ka hao, calcium, sodium), a haʻahaʻa ka nui o ka haumia.

Ka hoʻoheheʻe maikaʻi:Lanthanum Sulfate Hydrare hiki ke hoʻoheheʻe koke i ka wai a me nā waikawa ikaika.

Kūlike: ʻO ka hoʻokele puʻupuʻu koʻikoʻi i ka hana ʻana oLanthanum Sulfate Hydrare

hōʻoia i ka maikaʻi paʻa no ka hana ʻana i ka ʻoihana nui.

Mea hoʻouluulu ʻoihana kemika: ʻO ka hydrated lanthanum sulfate kahi ʻāpana koʻikoʻi o ka mea hoʻouluulu catalytic cracking (FCC) i hoʻohana ʻia i ka ʻoihana petrochemical. Hiki iā ia ke hoʻonui pono i ka pono o ka hoʻololi ʻana i ka ʻaila maka kaumaha i loko o ka gasoline octane kiʻekiʻe a me ka diesel. Hiki iā ia ke lawelawe ma ke ʻano he mea hoʻouluulu a i ʻole mea hoʻouluulu mua no kekahi mau hopena synthesis organik.

Nā mea mālama wela kemika: Ma muli o kona mau ʻano hopena dehydration/hydration hiki ke hoʻohuli ʻia, he mea mālama wela kemika hoʻohiki nui ka lanthanum sulfate hydrate. Hiki iā ia ke hana i nā hopena hiki ke hoʻohuli ʻia i loko o kahi pae mahana haʻahaʻa (ma kahi o 100°C a i 250°C), a hoʻohana ʻia no ka hoʻōla ʻana a me ka mālama ʻana i ka wela ʻōpala ʻoihana. Loaʻa iā ia kahi mānoanoa mālama ikehu kiʻekiʻe a me ke kūpaʻa pōʻaiapuni maikaʻi loa.

Mea Hoʻohemo Phosphorus Loko: Ma muli o kona mau waiwai kemika, hiki i ka lanthanum sulfate ke wehe pono i ka phosphate mai nā kino wai ma o ka ua, he mea kōkua ia i ka hoʻoponopono ʻana i ka pilikia o ka eutrophication o ke kino wai.

Nā mea waena synthetic kemika: Ma ke ʻano he kumu nui o ka lanthanum, ʻo ka hydrated lanthanum sulfate kahi mea nui no ka synthesizing ʻana i nā hui lanthanum ʻē aʻe, a hoʻohana ʻia e hoʻomākaukau i nā mea hana like ʻole e like me ka lanthanum oxide a me nā phosphors e pili ana i ka lanthanum. Hoʻohana ʻia hoʻi ia ma ke ʻano he reagent i ka noiʻi ʻepekema e like me ka nānā ʻana o ka spectroscopy a me ka hoʻoholo ʻana i nā kaumaha atomika o nā mea.
