He aha ke ʻano o ka lāʻau lapaʻau e pono ai ke hoʻohana ʻia no ka phosphate?He aha kāna hana ma mua o ka mālama ʻana?,
Pākē phosphate, Hebei phosphate, Phosphate, phosphate Kina, mea hana phosphate, mea hoʻolako phosphate,

3. Hoʻohana
mahiʻai: ʻO ka waikawa Phosphoric kahi mea waiwai nui no ka hana ʻana i nā fertilizers phosphate (superphosphate, potassium dihydrogen phosphate, etc.) ) nā mea maka.
ʻOihana: ʻO ka waikawa Phosphoric kahi mea waiwai nui, a ʻo kāna mau hana nui penei:
1. E mālama i ka ʻili metala a 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 hoʻoliʻiliʻi kemika e hoʻomaikaʻi i ka maʻalahi o ka ʻili metala.
3. Phosphatenā esters, nā mea maka no ka hana ʻana i nā mea holoi a me nā pesticides.
4. Nā mea maka no ka hana ʻana i nā mea hoʻopaʻa ahi me ka phosphorus
Meaʻai: ʻO ka waikawa Phosphoric kekahi o nā mea hoʻohui meaʻai.Hoʻohana ʻia ia i ka meaʻai ma ke ʻano he mea ʻawaʻawa a me ka mea hū.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.
ʻO ka ʻili metala "ka mālama phosphorification".ʻO ka mea i kapa ʻia ʻo phosphorus e pili ana i ke ʻano o ka hana ʻana i nā mea hana metala ma o ka hopena acidic i loaʻa i ka paʻakai dihydrogen -phosphate, a me ke ʻano o ka hana ʻana i kahi ʻāpana membrane phosphate insoluble paʻa ma luna o kona ʻili e hoʻohua i kahi hopena kemika.Kapa ʻia ka membrane he kiʻi phosphorum.ʻO ke kumu nui o ka kiʻi phosphorum e hoʻonui i ka hoʻopili ʻana o ke kiʻi ʻoniʻoni a hoʻomaikaʻi i ke kūpaʻa corrosion o ka uhi.Nui nā ala e phosphorify.Wahi a ka mahana i ka wā o ka phosphorusization, hiki ke hoʻokaʻawale ʻia i ka phosphorus kiʻekiʻe (90-98 ° C), ka phosphorus wela waena (60-75 ° C), ka phosphate haʻahaʻa haʻahaʻa (35-55 ° C) a me ka phosphorus lumi lumi N.
Hoʻohana nui ʻia ka ʻenehana passivation o ka phosphorum film ma ʻAmelika ʻĀkau a me nā ʻāina ʻEulopa.Hoʻohana ʻia ka hoʻohana ʻana i ka ʻenehana passivation i nā hiʻohiʻona o ke kiʻi phosphate ponoʻī.He lahilahi ka phosphorum film.ʻO ka maʻamau, ʻo ia ka 1-4g / m2, ʻaʻole i ʻoi aku ma mua o 10g / M2, nui kona wahi pore manuahi, a ʻo ke kiʻiʻoniʻoni ponoʻī i kaupalena ʻia ke kūpaʻa corrosion.He ʻele melemele koke kekahi i ka wā e hoʻomaloʻo ai.Ma hope o ka phosphorusization, hiki ke hoʻomaʻamaʻa hou ʻia kahi passivation a pani ʻia e ka metala i hōʻike ʻia i loko o nā pores o ke kiʻi phosphorurative, a i ʻole ka papa passivation.ʻO ka hopena oxidation e hoʻopaʻa i ka phosphate i ka lewa.

Hoʻohana ʻia ke kiʻi hoʻololi phosphate i ka hao, aluminika, zinc, cadmium, a me kāna mau ʻāpana, hiki ke hoʻohana ʻia e like me ka papa hoʻomaʻemaʻe hope a i ʻole ka papa waena o nā papa uhi ʻē aʻe.Loaʻa i kāna kuleana nā ʻano aʻe.

ʻOiai ʻo ka hoʻomaikaʻi ʻana i ke kiʻi phosphorurative he lahilahi, no ka mea, he non-metal non-conductive ka hoʻokaʻawale ʻana, hiki iā ia ke hoʻololi i ka conductor maikaʻi o ka ʻili o ka mea hana metala i loko o kahi conductor adverse, e kāohi i ka hoʻokumu ʻana o ka micro-electrical ma luna o ka ʻili. ka mea hana metala Ka ʻino o ke kiʻi uhi.Papa 1 i ka hopena o ke kiʻiʻoniʻoni phosphate ma ke kū ʻana i ka ʻino metala.
ʻO ka hoʻomaikaʻi ʻana i ka kiʻiʻoniʻoni adhesion ma waena o ka matrix a me ka uhi ʻana a i ʻole nā ​​​​papa hoʻonaninani kūlohelohe he paʻa paʻa holoʻokoʻa e hui pū ai i kahi hui kokoke.ʻAʻohe palena maopopo i ka wā.ʻO nā waiwai porous o ka phosphorurative film e hana i ka mea pani pani, nā uhi, a me nā mea'ē aʻe e komo i loko o kēia mau pores, a pili pono i ka membrane phosphoridized, i mea e hoʻomaikaʻi ai i ka pili.

Hāʻawi i kahi kiʻiʻoniʻoni phosphorus maʻemaʻe hiki ke ulu wale ma luna o ka ʻili o ka mea hana metala me ka ʻole o ka haumia aila a me ka papa ʻaʻa ʻole.No laila, hiki i nā mea hana metala i phosphorus ke hāʻawi i nā ʻili maʻemaʻe, ʻaʻahu, momona ʻole a me ka ʻōpala.
