Polyaluminium chlorideinonyatso shanda flocculant, inowanzo shandiswa mumaseji esuweji nemaindasitiri emarara emvura. Iine maitiro ekushanda kwepamusoro uye kugadzikana. Kana tichitaura nezve PAC, chimwe chezviratidzo chinowanzo taurwa ndechekukosha. Saka chii chinonzi basicity? Ndeipi mhedzisiro ine basicity pamhando yepolyaluminium chloride? Kunzwisisa pfungwa iyi kuchave nekukanganisa kukuru pakusarudzwa kwe polyaluminium chloride.
Chii chinonzi basic mu polyaluminium chloride?
MuPAC, basicity inoreva chiyero chemolar chemapoka ehydroxyl kune aluminium ion. Inowanzo kuratidzwa sechinhu chakakosha (B):
B = [OH-] / [Al3+]
Basicity ndeimwe yeakanyanya kukosha ekuita zviratidzo zve polyaluminium chloride. Iyo inobata zvakananga iyo flocculation mhedzisiro yePAC.
Kambani yedu inopa akasiyana marudzi ePAC ane basicity kubva pa40% kusvika 90%.
Iyo meshini yekupesvedzera kweiyo basic pa polyaluminium chloride
Basicity inokanganisa mashandiro ePAC nekukanganisa iyo polymer morphology uye kuchaja kugovera kwePAC. Alkalinity inosarudza dhigirii repolymerization yealuminium hydroxyl complexes muPAC. Yepamusoro basicity inokodzera kuumbwa kwePAC ine yakakwira polymerization degree uye inovandudza flocculation yayo. Uye izvo zvakakosha zvinokanganisa kugovera kwakanaka kwePAC uye kugona kwayo kweadsorption yezvinhu zvinopomerwa zvisina kunaka.
Mhedzisiro yezvakakosha paPAC:
Yakakodzera basicity inogona kukwirisa iyo flocculation mhedzisiro ye polyaluminium chloride. Kunyanya kuderera kwekutanga kunotungamira kune isina kukwana hydrolysis yePAC uye kuderedza iyo flocculation maitiro.
Basicity ichakanganisawo saizi, density uye sedimentation rate yepolyaluminium chloride condensed flocs. Hunhu hwakakodzera hunogona kubata chikamu ichi zvakanaka kwazvo.
Naizvozvo, zvinonyanya kukosha kusarudza yakakodzera PAC modhi zvinoenderana nezvaunoda.
Tinogona kupa zvinotevera PAC modhi:
| Item | PAC-I | PAC-D | PAC-H | PAC-M | PAC-G |
| Chitarisiko | Yellow powder | Yellow powder | Upfu chena | Upfu hwemukaka | Milky White poda |
| Zvemukati (%, Al2O3) | 29±1 | 30±1 | 30±1 | 30±1 | 30±1 |

Isu tinoitisa hutongi hwemhando yepamusoro pamafekitori edu epolyaluminium chloride uye tinokwanisa kuita kurudziro yemhando zvinoenderana nezvinodiwa nevatengi zvakasiyana, tichipa vatengi vane yepamusoro-mhando PAC inosangana nezvavanoda. Chikwata chedu chekutengesa chine ruzivo rwakapfuma mukusarudza kwechigadzirwa uye chinogona kupa vatengi zano reunyanzvi uye masamples ane hunyanzvi hwevatengi kuti vaite bvunzo dzebeaker.
Kana uri kutsvaga akavimbikaPAC Mutengesiyekuchenesa mvura yekunwa, indasitiri yetsvina kurapa kana zvimwe zvikumbiro, tinogona kupa tsika PAC kuti isangane nezvido zvako. Bata isu izvozvi kuti udzidze zvakawanda nezve yedu yepamusoro-inoshanda PAC zvigadzirwa uye uwane yemakwikwi quote!
