ʻO ka waikawa Phosphoric 85%
Hōʻike huahana
ʻO ka waikawa Phosphoric, i ʻike ʻia hoʻi ʻo ka orthophosphoric acid, he waikawa inorganic i hoʻohana mau ʻia i nā ʻoihana like ʻole. He ʻakika ikaika kona, ʻo H3PO4 kona ʻano kemika, a ʻo kona kaumaha molekala he 97.995. ʻAʻole like me kekahi mau ʻakika volatile, paʻa ka waikawa phosphoric a ʻaʻole hiki ke wāwahi maʻalahi, e lilo ia i koho hilinaʻi no nā ʻano noi. ʻOiai ʻaʻole ikaika ka phosphoric acid e like me ka hydrochloric, sulfuric, a i ʻole nitric acids, ʻoi aku ka ikaika ma mua o ka acetic a me ka boric acid. Eia kekahi, loaʻa i kēia ʻakika nā waiwai maʻamau o kahi waikawa a hana ʻia ma ke ʻano he ʻakika tribasic nāwaliwali. He mea pono e hoʻomaopopo he hygroscopic ka waikawa phosphoric a hoʻopili koke i ka wai mai ka lewa. Eia kekahi, hiki iā ia ke hoʻololi i ka waikawa pyrophosphoric i ka wā i wela ai, a hiki i ka nalowale o ka wai ke hoʻololi iā ia i ka waikawa metaphosphoric.

Hoʻohana:
ʻO ka versatility o ka phosphoric acid he mea nui ia i nā ʻoihana like ʻole, ʻoi aku ka lāʻau lapaʻau, ka meaʻai a me ka hana fertilizer. I ka lāʻau lapaʻau, hoʻohana nui ʻia ia ma ke ʻano he anti-rust agent a ma ke ʻano he mea hoʻohui i nā kaʻina niho a me nā orthopedic. Ma ke ʻano he mea hoʻohui meaʻai, e hōʻoia i ka maikaʻi o ka huahana. Hoʻohana ʻia ka waikawa Phosphoric ma ke ʻano he etchant i ka electrochemical impedance spectroscopy (EDIC) a ma ke ʻano he electrolyte, flux a me ka dispersant i nā kaʻina hana ʻenehana. ʻO kāna mau waiwai corrosive e lilo ia i mea waiwai pono no nā mea hoʻomaʻemaʻe ʻoihana, ʻoiai i ka mahiʻai ʻo phosphoric acid kahi mea nui o nā fertilizers. Eia kekahi, he mea koʻikoʻi ia i nā huahana hoʻomaʻemaʻe hale a hoʻohana ʻia ma ke ʻano he mea kemika.
I ka hōʻuluʻulu ʻana, ʻo ka phosphoric acid kahi mea pono multifunctional pūhui i hoʻohana nui ʻia i nā ʻoihana like ʻole. ʻO kona ʻano kūpaʻa a me ka ʻole, i hui pū ʻia me kona acidity haʻahaʻa, e lilo ia i koho mua no nā noi he nui. ʻO ka nui o ka hoʻohana ʻana o ka waikawa Phosphoric, mai nā lāʻau lapaʻau a i nā mea hoʻohui meaʻai, mai nā kaʻina hana niho a hiki i ka hana fertilizer, hōʻike i kona koʻikoʻi i ka hana ʻana a me ke ola o kēlā me kēia lā. Inā he caustic, electrolyte a mea hoʻomaʻemaʻe paha, ua hōʻoia kēia waikawa i kona pono a me ka hilinaʻi. Me kona ākea ākea o nā noi a me nā waiwai pono, ʻo ka phosphoric acid kahi waiwai waiwai ma waena o nā ʻoihana.
