Kemimi Pengfa - E mālama i ka hoʻohana ʻana i ka waikawa phosphoric

      ʻakika Phosphoriche ʻakika inorganic maʻamau me ke ʻano kemika H3PO4.ʻAʻole maʻalahi i ka volatilize, ʻaʻole maʻalahi e decompose, maʻalahi i ka deliquescence i ka lewa.ʻO ka ʻakika Phosphoric kahi ʻakika ikaika me ka helu crystallization o 21°C.Ke emi ka mahana ma mua o kēia wela, e hoʻoheheʻe ʻia nā kristal hemihydrate.E lilo ana ka wai i ka wela no ka loaʻa ʻana o ka waika pyrophosphoric, a laila e lilo hou ka wai no ka loaʻa ʻana o ka waikawa metaphosphoric.ʻO ka waikawa Phosphoric ka waiwai o ka waikawa, ʻoi aku ka nāwaliwali o kona acidity ma mua o ka waika hydrochloric, sulfuric acid, nitric acid, akā ʻoi aku ka ikaika ma mua o ka acetic acid, boric acid, etc.

hoʻohana:

Lapaʻau: Hiki ke hoʻohana ʻia ka waikawa Phosphoric e hoʻomākaukau ai i nā lāʻau lapaʻau i loaʻa i ka phosphorus, e like me ka sodium glycerophosphate.Mahiʻai: ʻO ka waikawa Phosphoric kahi mea waiwai nui no ka hana ʻana i nā fertilizers phosphate (superphosphate, potassium dihydrogen phosphate, a me nā mea ʻē aʻe), a me ka hana ʻana i nā meaʻai meaʻai (calcium dihydrogen phosphate);

Meaʻai: ʻO ka waikawa Phosphoric kekahi o nā mea hoʻohui meaʻai.Hoʻohana ʻia ia ma ke ʻano he meaʻawaʻawa a me ka meaʻai hū i ka meaʻai.Loaʻa i ka Coca-Cola ka waikawa phosphoric.ʻO ka Phosphate kekahi mea hoʻohui meaʻai koʻikoʻi a hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻonui meaʻai;

ʻOihana: ʻO ka waikawa Phosphoric kahi mea kemika nui, a ʻo kāna mau hana nui e like me kēia;

1. 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;

2. Hoʻohui ʻia me ka waikawa nitric ma ke ʻano he mea hoʻoliʻi kemika e hoʻomaikaʻi i ka maʻalahi o ka ʻili metala;

3. Phosphate esters, nā mea maka no ka hanaʻana i nā mea holoi a me nā pesticides;

4. ʻO nā mea maka no ka hana ʻana i nā mea pale ahi i loaʻa i ka phosphorus;

E mālama i ka hoʻohana ʻana i ka waikawa phosphoric:

No ka pale ʻana i ka ʻili mai ka waikawa phosphoric, paipai mākou e hoʻokomo i nā lole pale kemika e like me nā kāmaʻa, nā lole pale a me nā mīkina lima, ke paipai pū nei mākou iā ʻoe e kūʻai i nā ʻili i hana ʻia me ka ʻili maoli, polyvinyl chloride, nitrile rubber, butyl rubber a i ʻole nā ​​mea pale neoprene.

No ka pale ʻana i ka maka a i ʻole nā ​​maka mai nā mea hoʻonāukiuki a me nā mea ʻino, paipai mākou i ka hoʻohana ʻana i nā goggles palekana no ka pale kemika.

Ma waho aʻe o ka hoʻoheheʻe ʻana o ka honua, paipai mākou i ka hoʻohana ʻana i ka hoʻoheheʻe ʻana o ka ʻāina e pale i ka pilikia o ka hanu i ka wā e hoʻohana ai i ka phosphoric acid, pono e mālama ʻia nā mea āpau e pono ai ke kaiapuni, a pono paha e hoʻoheheʻe ʻia ka uahi ma waho.
