Hoʻohana a hoʻohana i nā hiʻohiʻona o ka phosphoric acid

Nā hiʻohiʻona hoʻohana a me ka hoʻohana ʻana i ka waikawa phosphoric,
ʻakika Phosphoric, mea hana phosphoric acid, ʻO ka manaʻo o ka mea hana phosphoric acid, kumu hoʻohālike phosphoric acid, Mea kūʻai aku i ka ʻakika Phosphoric, ka hoʻohana a me ka hana o ka waikawa phosphoric,
Nā waiwai physicochemical:
1. Ka wai alohilohi kala ʻole, ʻAʻohe ʻala irritant
2. Ka helu heheʻe 42 ℃; kahi e hoʻolapalapa ai 261 ℃.
3.Miscible me ka wai i kekahi lakio

Storge:
1. E kūʻai i loko o kahi hale kūʻai maʻalili.
2. E mālama i ke ahi a me nā kumu wela.
3. Hoʻopaʻa ʻia ka pūʻolo.
4. Pono e mālama ʻokoʻa ʻia mai nā mea hoʻopau maʻalahi, alkalis, a me nā pauka metala ikaika, a pale i ka waiho ʻana.
5. Pono e hoʻolako ʻia ka wahi mālama me nā mea kūpono e loaʻa ai ka leakage.

ʻakika Phosphoricno ka hana ʻoihana
ʻO ka ʻōlelo kikoʻī (GB/T 2091-2008)

Mea hoʻohui meaʻai Phosphoric acid
ʻO nā kikoʻī maikaʻi (GB/T 1886.15-2015)

E hoʻohana:
Ka hoʻohana ʻana i ka mahiʻai: nā mea maka o ka phosphate fertilizera me nā meaʻai hānai
Hoʻohana i ka ʻoihana: nā mea maka kemika
1. Mālama i ka metala mai ka ʻino
2.Mixed me ka waikawa nitric e like me ke kinikini polishing agentto hoʻomaikaʻi i ka ʻili o ka metala
3. Material o ka phosphatide i hoʻohana ʻia no ka huahana holoi ʻana a me ka insecticide
4. ʻO ka hana ʻana o ka phosphorus i loaʻa nā mea flameretardant.
Hoʻohana ʻia nā mea hoʻohui meaʻai: ka mea ʻono acidic, Yeast Nutri-ents, , e like me ka coca-cola.
Hoʻohana lāʻau lapaʻau: e hana i ka lāʻau lapaʻau i loaʻa ka phos-phorus, e like me Na 2 Glycerophosphat

ʻO kaʻakika Phosphoric a iʻole ka waika orthophosphoric, ke kumu hoʻohālike H3PO4, ke kaumaha molekala 97.9724, heʻakika inorganic maʻamau, he waikawa ikaika. Loaʻa ia ma ka hoʻoheheʻe ʻana i ka phosphorus tetroxide i ka wai wela. Loaʻa ka waika Orthophosphoric ma ke kālepa ma o ka mālama ʻana i ka apatite me ka waikawa sulfuric. ʻO ka waika Phosphoric dehydrates maʻalahi i ka ea. Lilo ka wai i ka wai i ka pyrophosphoric acid, a lilo hou ka wai i metaphosphate. Hoʻohana nui ʻia ka waikawa Phosphoric i ka lāʻau lapaʻau, ka meaʻai, ka mea momona a me nā ʻoihana ʻē aʻe, a hiki ke hoʻohana ʻia e like me ka reagent kemika.
Hoʻolālā waiwai
ʻO Orthophosphate he waikawa phosphoric i haku ʻia me ka tetrahedron phospho-oxygen hoʻokahi. I loko o ka mole mole ʻakika phosphoric, ua hoʻohui ʻia ka P atom i ka sp3 hybrid, ʻekolu orbital hybrid i ʻekolu mau kaula sigma me ka oxygen atom, a ʻo ka mea paʻa ʻē aʻe P - O ua hana ʻia i hoʻokahi paʻa sigma mai ka phosphorus a i ka oxygen a me ʻelua mau paʻa d-pπ mai. oxygen i ka phosphorus. Hoʻokumu ʻia kahi paʻa sigma e ka hoʻohui ʻana o kahi pālua o nā electrons mai kahi atom phosphorus i kahi orbital hakahaka o kahi ʻātoma oxygen. Hoʻokumu ʻia ka paʻa d←p ma ke kau ʻana i ka py a me ka pz o nā ʻātoma oxygen me nā orbital hakahaka o dxz a me dyz o nā ʻātoma phosphorus. No ka mea, ʻoi aku ka kiʻekiʻe o ka ikehu 3d o nā ʻātoma phosphorus ma mua o ka ikehu 2p o nā ʻātoma oxygen, ʻaʻole maikaʻi loa nā orbital mole, no laila, ʻo nā mea paʻa PO he mau paʻa ʻekolu ma ke ʻano o ka helu, akā waena ma waena o nā paʻa hoʻokahi a me nā paʻa pālua e pili ana i ka ikehu paʻa. a me ka lōʻihi pili. ʻO ka loaʻa ʻana o nā paʻa hydrogen i loko o ka H3PO4 maʻemaʻe a me kāna mau hydrates crystalline hiki ke helu i ka viscosity o ka solution phosphoric acid.

Kahua noi
Mahiai: ʻO ka waikawa Phosphoric kahi mea maka no ka hana ʻana i nā mea kanu phosphate koʻikoʻi (calcium superphosphate, potassium dihydrogen phosphate, etc.), a no ka hana ʻana i nā meaʻai meaʻai (calcium dihydrogen phosphate).

ʻOihana: ʻO ka waikawa Phosphoric kahi mea waiwai nui. ʻO kāna mau hana nui penei:

E mālama i ka ʻili metala e hana i kahi kiʻiʻoniʻoni phosphate insoluble ma ka ʻili metala e pale i ka metala mai ka ʻino.
Hoʻohana ʻia e like me ka polish kemika i hui pū ʻia me ka waikawa nitric e hoʻomaikaʻi i ka pau ʻana o nā ʻili metala.
ʻO ka hana ʻana o ka mea holoi, pesticide maka mea phosphate ester.
ʻO nā mea waiwai no ka hana ʻana i nā mea pale ahi phosphorous.
Meaʻai: ʻO ka waikawa Phosphoric kekahi o nā mea hoʻohui meaʻai, i ka meaʻai ma ke ʻano he mea ʻono ʻawaʻawa, ka mea hū meaʻai meaʻai, Coca-Cola loaʻa ka phosphoric acid. ʻO Phosphates kekahi mea hoʻohui meaʻai koʻikoʻi a hiki ke hoʻohana ʻia i mea hoʻonui meaʻai.

Lapaʻau: Hiki ke hoʻohana ʻia ka waikawa Phosphoric e hana i nā lāʻau lapaʻau phosphorous, e like me ka sodium glycerophosphate.
