He ʻakika ikaika ia me ke ʻano kemika H3PO4 a me ke kaumaha molekala o 97.995. ʻAʻole volatile, ʻaʻole maʻalahi e decompose, aneane ʻaʻohe oxidation.
Hoʻohana nui ʻia ka phosphoric acid i ka lāʻau lapaʻau, ka meaʻai, ka mea kanu a me nā ʻoihana ʻē aʻe, e like me nā mea hoʻopiʻi rust, nā mea hoʻohui meaʻai, nā niho a me nā orthopedic, EDIC caustics, electrolytes, flux, dispersants, caustics industrial, fertilizers e like me nā mea maka a me nā ʻāpana o nā huahana hoʻomaʻemaʻe hale. , a hiki ke hoʻohana ʻia e like me nā mea hana kemika.
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:ʻakika Phosphoric he mea waiwai nui kemika. ʻO kāna mau hana nui penei:
1, ka mālama ʻana i ka ʻili metala, ka hoʻokumu ʻana o ke kiʻiʻoniʻoni phosphate insoluble ma ka ʻili metala, e pale i ka metala mai ka ʻino.
2, hui pū ʻia me ka waikawa nitric e like me ka polish kemika, e hoʻomaikaʻi i ka pau ʻana o ka ʻili metala.
3, ka hana o ka holoi holoi, insecticide maka mea phosphate ester.
4, ka hana ʻana o nā mea maka i loaʻa i ka phosphorus flame retardant.
Meaʻai:ʻakika phosphoric ʻO ia kekahi o nā mea hoʻohui meaʻai, i loko o ka meaʻai ma ke ʻano he mea ʻawaʻawa, ka mea hū meaʻai meaʻai, aia ka cola i ka waikawa phosphoric. 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.
