Kodi kusiyana pakati pa ACH ndi PAC ndi kotani?

Aluminium chlorohydrate (ACH) ndi polyaluminum chloride (PAC) zikuwoneka kuti ndi mankhwala awiri osiyana omwe amagwiritsidwa ntchito ngati mankhwala.flocculants mu mankhwala a madziNdipotu, ACH ndi chinthu chokhazikika kwambiri m'banja la PAC, chomwe chimapereka alumina wambiri komanso kukhazikika komwe kungatheke m'njira zolimba kapena njira zokhazikika. Awiriwa ali ndi magwiridwe antchito osiyana pang'ono, koma madera omwe amagwiritsidwa ntchito ndi osiyana kwambiri. Nkhaniyi ikupatsani kumvetsetsa kwakukulu kwa ACH ndi PAC kuti musankhe chinthu choyenera.

Polyaluminum chloride

Polyaluminum chloride (PAC) ndi polima yokhala ndi mamolekyu ambiri yokhala ndi formula ya mankhwala [Al2(OH)nCl6-n]m. Chifukwa cha mawonekedwe ake apadera a mankhwala, imagwiritsidwa ntchito m'njira zosiyanasiyana. Polyaluminum chloride (PAC) imagwira ntchito yofunika kwambiri pakuchiza madzi, kuchotsa bwino zinthu zolimba zomwe zapachikidwa, zinthu za colloidal, ndi zinthu zachilengedwe zosasungunuka kudzera mu njira zolumikizirana. Mwa kuletsa tinthu tating'onoting'ono, PAC imalimbikitsa kusonkhana, zomwe zimathandiza kuti tichotsedwe m'madzi. PAC, yomwe nthawi zambiri imagwiritsidwa ntchito limodzi ndi mankhwala ena monga PAM, imawonjezera ubwino wa madzi, kuchepetsa kutayikira, komanso kukwaniritsa miyezo yamakampani.

Mu gawo lopanga mapepala, PAC imagwira ntchito ngati flocculant yotsika mtengo komanso yowononga zinthu, yowongolera njira zoyeretsera zinyalala komanso kukula kwa rosin-neutral. Imawonjezera kukula kwake, kuteteza kuipitsidwa kwa nsalu ndi makina.

Ntchito za PAC zimafikira makampani opanga migodi, zimathandiza kutsuka miyala ndi kulekanitsa mchere. Zimalekanitsa madzi ndi gangue, zimathandiza kugwiritsanso ntchito, komanso zimachotsa madzi m'matope.

Pochotsa ndi kuyeretsa mafuta, PAC imachotsa zinyalala, zinthu zachilengedwe zosasungunuka, ndi zitsulo m'madzi otayidwa. Imachotsa ndikuchotsa madontho a mafuta, kukhazikika kwa mabowo a zitsime ndikuletsa kuwonongeka kwa mapangidwe panthawi yobowola mafuta.

Kusindikiza ndi kupaka utoto nsalu kumapindula ndi luso la PAC lotha kuyeretsa madzi otayidwa ndi madzi ambiri komanso zinthu zambiri zoipitsa zachilengedwe. PAC imalimbikitsa kukhazikika kwa maluwa a alum mwachangu, zomwe zimapangitsa kuti pakhale zotsatira zabwino kwambiri pa chithandizo.

Aluminiyamu ya Chlorohydrate

ACH, Aluminium Chlorohydrate, yokhala ndi formula ya molekyulu Al2(OH)5Cl·2H2O, ndi polima yopanda organic yomwe ili ndi digiri yapamwamba ya alkaliization poyerekeza ndi polyaluminum chloride ndipo imatsata aluminiyamu hydroxide yokha. Imadutsa mu bridge polymerization kudzera m'magulu a hydroxyl, zomwe zimapangitsa kuti molekyuluyo ikhale ndi magulu ambiri a hydroxyl.

ACH imapezeka mu mankhwala oyeretsera madzi ndi mankhwala a tsiku ndi tsiku (mtundu wa zodzoladzola), imabwera mu ufa (wolimba) ndi madzi (wamadzi), ndipo cholimbacho chimakhala ufa woyera ndipo yankholo ndi madzi owonekera opanda mtundu.

Zinthu zosasungunuka ndi kuchuluka kwa Fe ndizochepa, kotero zitha kugwiritsidwa ntchito m'magawo a mankhwala tsiku ndi tsiku.

ACH imagwiritsa ntchito zinthu zosiyanasiyana. Imagwira ntchito ngati chinthu chopangira mankhwala ndi zodzoladzola zapadera, makamaka ngati chinthu chachikulu choletsa thukuta chomwe chimadziwika kuti chimagwira ntchito bwino, sichimayambitsa kuyabwa kwambiri, komanso sichimateteza. Kuphatikiza apo, ACH ndi yokwera mtengo ndipo chifukwa chake sigwiritsidwa ntchito kawirikawiri ngati chotsukira madzi m'madzi akumwa komanso pochiza madzi otayidwa m'mafakitale. ACH imasonyezanso kukhuthala kogwira ntchito pa pH yochuluka kuposa mchere wamba wachitsulo ndi polyaluminum chloride wochepa.
