Pehea ka nui o kou ike no ia? Maopopo iā ʻoe he aha kāna kumu?,
Nā mea hana Kina, nā mea hana hale, nā mea hana phosphate, kumukūʻai phosphate, ke kumukuai o ka phosphate, he aha ka pono o ka phosphate,
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.

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
Ma hope o ka loaʻa ʻana o ka phosphorus a me ka German chemist Conquer e hana i ka phosphorus, ua hana kūʻokoʻa ʻo British chemist Bo Yili i ka phosphorus. ʻO ia hoʻi ka mea lapaʻau mua i aʻo i ka phosphorus a me nā pūhui. Ua kākau ka thesis "A New Experiment of the Cold Light Observed" "Hoʻopuka ka Phosphorus i ka uahi keʻokeʻo ma hope o ka puhi ʻana, a ʻo ka hopena i hana ʻia ma hope o ka hana ʻana o ka uahi keʻokeʻo a me ka wai he waikawa." ), A ʻo ka hopena i hana ʻia me ka wai he phosphate, akā ʻaʻole ʻo ia i aʻo hou i ka phosphate.
ʻO ka chemist mua loa i aʻo i ka phosphate ʻo ia ka mea lapaʻau Farani ʻo Lawar. I ka makahiki 1772, ua hana ʻo ia i kahi hoʻokolohua: E kau i ka phosphorus i loko o kahi uhi bele i hoʻopaʻa ʻia i ka mercury e puhi ai. Ua hoʻoholo ʻia nā hopena hoʻokolohua e hiki ke puhi ʻia kahi nui o ka phosphorus i kahi ea o ka mana; Hoʻokumu ʻia nā ʻāpana pauka keʻokeʻo o ka phosphorus i ka wā e wela ai ka phosphorus, e like me ka hau maikaʻi; 80%; ʻO ka phosphorus ma kahi o 2.5 mau manawa ma mua o ke ahi; hoʻoheheʻe ʻia ka pauka keʻokeʻo i loko o ka wai e hana i ka phosphate. Hōʻike pū ʻo Lavis e hiki ke hana ʻia ka phosphate me ka nitric acid a me ka phosphorus.
Ma hope o 100 mau makahiki, ua hana ʻo Libii chemist Kelemania i nā hoʻokolohua kemika mahiʻai e wehe i ka waiwai o ka phosphorus a me ka phosphate i ke ola mea kanu. I ka makahiki 1840, ua hōʻike ʻepekema ʻo Li Bixi "The role of organic chemistry in griculture and physiology" i ka pilikia o ka momona o ka lepo a kuhikuhi i ke kuleana o ka phosphorus ma nā mea kanu. I ka manawa like, ua ʻimi hou ʻo ia i ka hoʻohana ʻana i ka phosphate a me ka phosphate i mea hoʻomomona, a ua komo ka hana ʻana o ka phosphate i kahi wā nui.
