ʻAka Phosphoric
Nā waiwai physicochemical:
1. Ka wai alohilohi kala ʻole, ʻAʻohe ʻala ʻeha.
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.

E hoʻohana:
Ka hoʻohana ʻana i ka mahiʻai: mea maka o ka phosphate fertilizerand hānai meaʻai.
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: mea ʻono ʻakika, Yeast Nutri-ents, , e like me ka coca-cola.
Hoʻohana lāʻau lapaʻau: e hana i ka lāʻau i loaʻa i ka phos-phorus, e like me Na 2 Glycerophosphat.
