ʻElua kaʻina hana o kalipuna koloriside, ʻo ke ʻano waika a ʻo ke ʻano alkali kekahi.
Hoʻomākaukau nui ʻia ke ʻano waikawa e ka hopena kemika o ka limestone a me ka waika hydrochloric. Ma kahi o 22% dilute hydrochloric acid e hoʻohana ʻia e hana me ka limestone (loaʻa ma kahi o 52% calcium) e hana i 27% wai calcium chloride. Ma hope o ka kānana a me ka hoʻokaʻawale ʻana, hoʻolei ʻia ke koena kānana. Hoʻopili ʻia ka filtrate me ka waiu lime e hoʻoponopono i ka pH = 8.9-9. ʻO nā haumia i loko o ka solution calcium chloride e like me aʻu, Fe, al1, a pēlā aku. He ʻōpala paʻa ka kānana kānana, Hoʻopili ʻia ka filtrate i ʻekolu hopena i hoʻokaʻawale ʻia i ka hoʻoheheʻe ʻana i ka vacuum e hoʻokaʻawale i ka 27% calcium chloride solution i 68-69%, a laila hānai ʻia i loko o ka flaker no ka hana ʻana. Hoʻomaloʻo ʻia ka flake calcium chloride i loko o ka moena wai e hana ai i 74% calcium chloride dihydrate.
ʻO ke ʻano alkaline e hoʻopuka ai i ka calcium chloride: 1. ʻO ke kaʻina hoʻoheheʻe pololei o ka calcium chloride: maʻamau, ʻo ka ʻike o ka calcium chloride i loko o ka wai ʻona o ka lehu soda he 76.8g/l. Ma hope o ka hoʻomaʻemaʻe ʻana, hoʻomaʻemaʻe mua ʻia, hoʻokaʻawale ʻia nā kristal pono ʻole, a laila hoʻopaʻa ʻia e loaʻa ka calcium chloride.
2. Calcium chloride paʻakai kahua pre evaporation kaʻina hana: maʻamau, hoʻohana ʻia ka laha paʻakai e hoʻoheheʻe maoli i ka wai ʻona ʻōpala. Hoʻopaʻa ʻia ka paʻakai i loko o ka wai ʻōpala, a ʻo ka paʻakai i loko o ka wai ʻōpala e hoʻoheheʻe mua ʻia. Me ka piʻi ʻana o ka evaporation, ʻoi aku ka nui o ka paʻakai. E hōʻiliʻili ʻia ke koena wai calcium chloride i loko o nā mea hana no ka hoʻoheheʻe ʻana, a loaʻa ka calcium chloride.
ʻO ka ʻokoʻa ma waena o nā kaʻina hana ʻelua, ʻoi aku ka paʻakikī o ka calcium chloride i hana ʻia e ke ʻano acid ma mua o ke ʻano alkali, akā ʻoi aku ka nui o nā haumia, ke kala paʻa ʻole a me ka ʻono, a ʻoi aku ka liʻiliʻi o ke ʻano acid ma mua o ke ʻano alkali. ʻO nā papa calcium chloride i loaʻa ma ke kaʻina hana alkali he lahilahi a palupalu, me ka maʻemaʻe kiʻekiʻe, nā mea haumia liʻiliʻi a me ke kala keʻokeʻo.
