Polyaluminum chloride ndi chotsukira madzi chogwira ntchito bwino kwambiri, chomwe chimatha kuyeretsa, kuchotsa fungo loipa, kuchotsa utoto, ndi zina zotero. Chifukwa cha makhalidwe ake abwino komanso ubwino wake komanso kugwiritsa ntchito kwake mosiyanasiyana, mlingo wake ukhoza kuchepetsedwa ndi zoposa 30% poyerekeza ndi zotsukira madzi zachikhalidwe, ndipo mtengo wake ukhoza kupulumutsidwa ndi zoposa 40%. Chakhala chotsukira madzi chabwino kwambiri chomwe chimadziwika kunyumba ndi kunja. Kuphatikiza apo, polyaluminum chloride ingagwiritsidwenso ntchito kuyeretsa madzi apadera monga madzi akumwa ndi madzi apampopi, monga kuchotsa chitsulo, kuchotsa cadmium, kuchotsa fluorine, kuchotsa zonyansa za radioactive, ndi kuchotsa mafuta otayirira.
PAC (Poly Aluminium Chloride) Makhalidwe:
Polyaluminum chloride ili pakati pa ALCL3 ndi ALNCL6-NLm] pomwe m imayimira mlingo wa polymerization ndipo n imayimira mlingo wa kusalowererapo kwa PAC. Polyaluminum chloride, yomwe yafupikitsidwa kuti PAC, nthawi zambiri imatchedwanso polyaluminum chloride kapena coagulant, ndi zina zotero. Mtundu wake ndi wachikasu kapena wachikasu chopepuka, bulauni wakuda, wakuda imvi resinous solid. Chogulitsachi chili ndi mphamvu zolimba zolumikizira, ndipo panthawi ya hydrolysis, njira zakuthupi ndi zamankhwala monga kugawanika, kulowetsedwa ndi mvula zimachitika.
PAC (Poly Aluminiyamu Chloride) Ntchito:
Polyaluminum chloride imagwiritsidwa ntchito kwambiri poyeretsa madzi ndi ngalande m'mizinda: madzi a m'mitsinje, madzi osungiramo madzi, madzi apansi panthaka; kuyeretsa madzi a m'mafakitale, kukonza zimbudzi za m'mizinda, kubwezeretsa zinthu zothandiza m'madzi a m'mafakitale ndi zinyalala, kulimbikitsa kusungunuka kwa malasha ophwanyidwa m'madzi a m'malasha, kupanga sitachi. Kubwezeretsanso sitachi; polyaluminum chloride imatha kuyeretsa madzi a m'mafakitale osiyanasiyana, monga: kusindikiza ndi kupaka utoto madzi a m'mafakitale, madzi a m'chikopa, madzi a m'madzi a m'fluorine, madzi a m'chitsulo cholemera, madzi a m'mafuta, kupanga mapepala, madzi a m'madzi a m'malasha, kukumba madzi a m'madzi a m'nyumba, kupanga madzi a m'madzi a m'nyumba, kupanga madzi a m'madzi a m'nyumba, kukonza madzi a m'madzi a m'nyumba, kukonza nyama, ndi zina zotero; Polyaluminum chloride yokonza zimbudzi: kupanga mapepala kukula, kukonza shuga, kupanga zinthu zopanga, kuteteza makwinya, chonyamulira chothandizira, kukonza simenti mwachangu, zopangira zokongoletsa.
Chizindikiro cha khalidwe la PAC (polyaluminum chloride)
Kodi zizindikiro zitatu zofunika kwambiri za PAC (polyaluminum chloride) ndi ziti? Mchere, PH, ndi kuchuluka kwa alumina zomwe zimatsimikiza mtundu wa polyaluminum chloride ndi zizindikiro zitatu zofunika kwambiri za polyaluminum chloride.
1. Mchere.
Mlingo wa hydroxylation kapena alkaliization wa mtundu winawake mu PAC (polyaluminum chloride) umatchedwa digiri ya basicity kapena alkalinity. Kawirikawiri imawonetsedwa ndi chiŵerengero cha molar cha aluminium hydroxide B=[OH]/[Al] percentage. Mchere ndi chimodzi mwa zizindikiro zofunika kwambiri za polyaluminum chloride, chomwe chimagwirizana kwambiri ndi flocculation effect. Madzi aiwisi akachuluka komanso mchere ukachuluka, flocculation effect imakhala yabwino. Mwachidule, pamlingo wa turbidity ya madzi osaphika ya 86~10000mg/L, mchere wabwino kwambiri wa polyaluminum chloride ndi 409~853, ndipo makhalidwe ena ambiri a polyaluminum chloride amagwirizana ndi mchere.
2. pH.
PH ya yankho la PAC (polyaluminum chloride) ndi chizindikiro chofunikira. Imayimira kuchuluka kwa OH- mu free state mu yankho. PH ya polyaluminum chloride nthawi zambiri imawonjezeka ndi kuwonjezeka kwa basicity, koma pa zakumwa zomwe zili ndi mitundu yosiyanasiyana, palibe ubale wofanana pakati pa pH ndi basicity. Madzi okhala ndi mchere wofanana amakhala ndi pH yosiyana pamene kuchuluka kwake kuli kosiyana.
3. Kuchuluka kwa aluminiyamu.
Kuchuluka kwa alumina mu PAC (polyaluminum chloride) ndi muyeso wa zigawo zogwira ntchito za mankhwalawa, zomwe zili ndi ubale wina ndi kuchuluka kwa yankho. Kawirikawiri, kuchuluka kwa alumina kumakhala kwakukulu, kuchuluka kwa alumina kumakhala kwakukulu. Kukhuthala kwa polyaluminum chloride kumagwirizana ndi kuchuluka kwa alumina, ndipo kukhuthala kumawonjezeka ndi kuchuluka kwa alumina. Pansi pa mikhalidwe yomweyi komanso kuchuluka komweko kwa alumina, kukhuthala kwa polyaluminum chloride kumakhala kotsika kuposa kwa aluminium sulfate, komwe kumakhala koyenera kunyamulidwa ndikugwiritsidwa ntchito.
