He aha ka Polyaluminium Chloride?
ʻO ka Polyaluminium chloride, i hoʻopōkole ʻia ʻo PAC, he mea hoʻōla wai polymer inorganic. Ua māhele ʻia nā ʻano i ʻelua mau māhele: ka hoʻohana ʻana i ka wai inu home a me ka hoʻohana ʻana i ka wai inu ʻole home, kēlā me kēia e pili ana i nā kūlana pili like ʻole. Ua māhele ʻia ke ʻano i ʻelua mau ʻano: wai a paʻa. Ma muli o nā ʻāpana like ʻole i loko o nā mea maka, aia nā ʻokoʻa i ke kala o ke ʻano a me nā hopena noi.
He mea paʻa kala ʻole a melemele paha ka Polyaluminium chloride. ʻO kona hopena he wai moakaka ʻole a melemele paha, hiki ke hoʻoheheʻe ʻia i ka wai a me ka waiʻona hoʻoheheʻe ʻia, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka waiʻona anhydrous a me ka glycerol. Pono e mālama ʻia i loko o kahi hale kūʻai anuanu, ea, maloʻo, a maʻemaʻe. I ka wā o ka halihali ʻana, pono e pale ʻia mai ka ua a me ka lā pololei, pale i ka deliquescence, a lawelawe me ke akahele i ka wā o ka hoʻouka ʻana a me ka wehe ʻana e pale aku i ka hōʻino ʻana o ka ʻōpala. ʻEono mahina ka manawa mālama no nā huahana wai, a hoʻokahi makahiki no nā huahana paʻa.
Hoʻohana nui ʻia nā mea hoʻomaʻemaʻe wai no ka hoʻomaʻemaʻe ʻana i ka wai inu, ka wai ʻino ʻoihana, a me ka wai ʻino kūloko o ke kūlanakauhale, e like me ka wehe ʻana i ka hao, fluorine, cadmium, ka haumia radioactive, a me ka ʻaila lana. Hoʻohana ʻia nō hoʻi no ka mālama ʻana i ka wai ʻino ʻoihana, e like me ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻino. Hoʻohana ʻia nō hoʻi ia i ka hoʻolei pololei ʻana, ka lāʻau lapaʻau, ka hana pepa, ka laholio, ka hana ʻili, ka ʻaila, ka ʻoihana kemika, a me nā mea hoʻoluʻu. Hoʻohana ʻia ka Polyaluminium chloride ma ke ʻano he mea mālama wai a me ka mea maka hoʻonaninani i ka mālama ʻili.
Loaʻa i ka Polyaluminium chloride ka adsorption, coagulation, precipitation a me nā waiwai ʻē aʻe. Loaʻa iā ia ka paʻa haʻahaʻa, ka ʻawaʻawa, a me ka corrosiveness. Inā pīpī ʻia ma ka ʻili, e holoi koke me ka wai. Pono nā limahana hana e komo i nā lole hana, nā masks, nā mīkina lima, a me nā kāmaʻa rapa lōʻihi. Pono e sila ʻia nā lako hana, a pono e maikaʻi ka ea o ka hale hana. Hoʻopau ka Polyaluminium chloride i ka wā e hoʻomehana ʻia ai ma luna o 110 ℃, e hoʻokuʻu ana i ke kinoea hydrogen chloride, a laila e hoʻopau i loko o ka alumini oxide; Hoʻopili me ka waikawa e hana i ka depolymerization, e hopena ana i ka emi ʻana o ke kekelē polymerization a me ka alkalinity, a laila e hoʻololi i ka paʻakai alumini. ʻO ka launa pū ʻana me ka alkali hiki ke hoʻonui i ke kekelē o ka polymerization a me ka alkalinity, a laila e alakaʻi ana i ka hoʻokumu ʻana o ka alumini hydroxide precipitate a i ʻole ka paʻakai aluminate; Ke hui pū ʻia me ka alumini sulfate a i ʻole nā paʻakai waikawa multivalent ʻē aʻe, hana maʻalahi ka precipitation, hiki ke hōʻemi a nalowale loa paha ka hana coagulation.
