He aha ka ʻokoʻa ma waena o ACH a me PAC?

ʻIke ʻia ʻo Aluminium chlorohydrate (ACH) a me ka polyaluminum chloride (PAC) he ʻelua mau pūhui kemika like ʻole i hoʻohana ʻia ma ke ʻano henā flocculants i ka mālama ʻana i ka waiʻO kaʻoiaʻiʻo, ʻo ACH ka mea i hoʻopaʻa nui ʻia i loko o ka ʻohana PAC, e hāʻawi ana i ka nui o ka alumina a me ke kumu kiʻekiʻe loa i hiki ke loaʻa i nā ʻano paʻa a i ʻole nā ​​ʻano hopena paʻa. He ʻokoʻa iki nā hana kikoʻī o nā mea ʻelua, akā he ʻokoʻa loa kā lākou mau wahi noi. E hāʻawi kēia ʻatikala iā ʻoe i kahi ʻike hohonu o ACH a me PAC i hiki iā ʻoe ke koho i ka huahana kūpono.

Polyaluminum chloride

ʻO ka Polyaluminum chloride (PAC) kahi polymer molekala kiʻekiʻe me ke ʻano kemika maʻamau [Al2(OH)nCl6-n]m. Ma muli o kona mau waiwai kemika kūikawā, he ākea kona mau noi ma nā ʻano like ʻole. He kuleana koʻikoʻi ko ka Polyaluminum chloride (PAC) i ka mālama ʻana i ka wai, e hoʻopau pono ana i nā mea paʻa i hoʻokuʻu ʻia, nā mea colloidal, a me nā mea olaola hiki ʻole ke hoʻoheheʻe ʻia ma o nā kaʻina hana coagulation. Ma ka hoʻopau ʻana i nā ʻāpana, paipai ka PAC i ka hōʻuluʻulu ʻana, e hoʻomaʻalahi ana i ko lākou wehe ʻana mai ka wai. ʻO ka PAC, i hoʻohana pinepine ʻia me nā kemika ʻē aʻe e like me PAM, hoʻonui i ka maikaʻi o ka wai, e hōʻemi ana i ka turbidity, a me ka hoʻokō ʻana i nā kūlana ʻoihana.

Ma ka ʻāpana hana pepa, lawelawe ʻo PAC ma ke ʻano he flocculant a me ka precipitant kūpono i ke kumukūʻai, e hoʻomaikaʻi ana i ka mālama ʻana i ka wai ʻino a me ka nui rosin-neutral. Hoʻonui ia i nā hopena nui, e pale ana i ka haumia o ka lole a me ka ʻōnaehana.

Hoʻonui ʻia nā noi a PAC i ka ʻoihana mining, e kōkua ana i ka holoi ʻana i ka ore a me ka hoʻokaʻawale ʻana i nā minerala. Hoʻokaʻawale ia i ka wai mai ka gangue, e hoʻomaʻalahi ana i ka hoʻohana hou ʻana, a hoʻomaloʻo i ka lepo.

I ka unuhi ʻana a me ka hoʻomaʻemaʻe ʻana i ka ʻaila, wehe ka PAC i nā mea haumia, nā mea olaola hiki ʻole ke hoʻoheheʻe ʻia, a me nā metala mai ka wai hoʻoneoneo. Hoʻoheheʻe ia a wehe i nā kulu aila, hoʻopaʻa i nā luawai a pale i ka hōʻino ʻia o ke ʻano i ka wā o ka ʻeli ʻana i ka aila.

Loaʻa ka pōmaikaʻi o ka paʻi ʻana a me ka hoʻoluʻu ʻana i nā lole mai ka hiki o PAC ke mālama i ka wai hoʻoneoneo me nā nui he nui a me ka nui o nā mea haumia organik. Paipai ka PAC i ka noho wikiwiki ʻana o nā pua alum, e hoʻokō ana i nā hopena mālama kupaianaha.

ʻAlumini Chlorohydrate

ʻO ACH, Aluminum Chlorohydrate, me ke ʻano molekala Al2(OH)5Cl·2H2O, he hui polymer inorganic e hōʻike ana i kahi kekelē alkalization kiʻekiʻe aʻe i hoʻohālikelike ʻia me ka polyaluminum chloride a me ka aluminum hydroxide trailing wale nō. Ke hele nei ia i ka polymerization alahaka ma o nā hui hydroxyl, e hopena ana i ka molekala e loaʻa ana ka helu kiʻekiʻe loa o nā hui hydroxyl.

Loaʻa i nā ʻano lapaʻau wai a me nā kemika o kēlā me kēia lā (papa hoʻonaninani), hele mai ʻo ACH i nā ʻano pauka (paʻa) a me ka wai (hoʻonā), me ka pauka keʻokeʻo ka mea paʻa a ʻo ka hopena he wai moakaka kala ʻole.

He haʻahaʻa ka mea hiki ʻole ke hoʻoheheʻe ʻia a me ka nui o Fe, no laila hiki ke hoʻohana ʻia i nā kahua kemika o kēlā me kēia lā.

Loaʻa iā ACH nā noi like ʻole. Hana ia ma ke ʻano he mea maka no nā lāʻau lapaʻau a me nā mea hoʻonani kūikawā, ʻoiai ʻo ia ka mea antiperspirant mua i ʻike ʻia no kona pono, ka huhū haʻahaʻa, a me ka palekana. Eia kekahi, he pipiʻi ke kumukūʻai o ACH a no laila ʻaʻole hoʻohana pinepine ʻia ma ke ʻano he flocculant i ka wai inu a me ka mālama ʻana i ka wai ʻino ʻoihana. Hōʻike pū ʻo ACH i ka condensation maikaʻi ma luna o kahi spectrum pH ākea ma mua o nā paʻakai metala maʻamau a me nā polyaluminum chlorides haʻahaʻa.
