Polyaluminum Chloride(PAC) ipolymer ine mamorekuru akawanda ine fomura yemakemikari yakajairika Al2(OH)nCl6-nm. Nekuda kwehunhu hwayo hwemakemikari hwakasiyana, ine mashandisirwo akasiyana-siyana muminda yakasiyana-siyana. Chinyorwa chino chinokutora zvakadzama mumunda kuti udzidze mashandisirwo chaiwo emusanganiswa uyu.
Chekutanga, PAC inoongorora zvakanyanya kurapwa kwemvura. Inogona kubvisa zvinobudirira zvinhu zvakamiswa, zvinhu zvecolloidal, zvinhu zvisinganyungudike zvechisikigo, uye kunyange zvidimbu zvakakura kwazvo mumvura. Izvi zvinoitwa kuburikidza nemaitiro anonzi coagulant, apo PAC inoshanda se coagulant. Inobvisa shongwe dzepamusoro, zvichiita kuti dziungane kuita zvidimbu zvikuru zvinogona kuparadzaniswa nyore nyore nemvura. Mugumisiro wacho mvura yakajeka uye yakachengeteka inosangana nezvinodiwa zvemhando dzakasiyana siyana, kusanganisira mvura yemumaindasitiri. PAC inoshandiswawo mukuchenesa mvura kubvisa zvidimbu zvakamiswa uye kuvandudza kunaka kwemvura nekuderedza kusvibiswa. Inowanzo shandiswa pamwe chete nemamwe makemikari ekurapa mvura, akadai sePAM, nezvimwewo, kuti iwane mhedzisiro yakanaka.
Polyaluminum chloride (PAC) inogona kushandiswa semushonga wekugadzira mapepa muindasitiri yekugadzira mapepa emvura yakachena. PAC inoshanda zvakanaka uye ine mutengo wakaderera, uye inofarirwa nevagadziri vemapepa. Pamusoro pezvo, inoshandawo semushonga unochengetedza, unochengetedza uye unosefa saizi yerosin-neutral, izvo zvinogona kuvandudza saizi uye kudzivirira kusvibiswa kwemachira emuchina wemapepa, slurry dzekugadzira mapepa uye masisitimu emvura machena nezvigadzirwa zve hydrolyzate.
Polyaluminum chloride flocculants inoshandawo zvakanaka muindasitiri yemigodhi. Inoshandiswa mukusuka matombo uye inoita basa guru mukupatsanurwa kwezvicherwa. Kune rumwe rutivi, inoparadzanisa mvura kubva kugangue zvinobudirira kuti ishandisezve mvura; kune rumwe rutivi, inobvisawo mvura kubva mumarara anogadzirwa.
Muindasitiri yepeturu, PAC ine chinzvimbo chakakoshawo. Inoshandiswa kubvisa tsvina kubva mumafuta panguva yekubvisa nekunatsa mafuta. Haingobvisi chete zvinhu zvisinganyunguduke, simbi nezvimwe zvinhu zvinokuvadza mumvura yakasviba, asiwo inobvisa madonhwe emafuta akasungirirwa mumvura. Painochera matsime emafuta, PAC inobatsirawo kudzikamisa tsime remvura uye kudzivirira kukuvara kwemafuta. Nekuisa jekiseni mutsime remvura, inodzivirira kumanikidzwa kwemafuta, ichideredza kukuvara kunogona kuitika. Izvi zvinokonzerwa nehunyanzvi hwePAC semushonga wejelling uye tackifier.
Indasitiri yekudhinda nekudhaya machira inzvimbo yakakosha yekushandiswa kwePAC. Sezvo mvura yakasviba inogadzirwa neindasitiri iyi iine hunhu hwekuwanda, ruvara rwakadzama, uye huwandu hwakawanda hwezvinhu zvinosvibisa zvipenyu, zvinova zvakaoma kurapa. Zvisinei, kuburikidza nekushanda kwePAC, maruva e alum panguva yekurapa mvura yakasviba akasimba uye akakura, anogadzikana nekukurumidza, uye mhedzisiro yekurapa inoshamisa.
Pamusoro peminda iri pamusoro apa, PAC inewo basa muindasitiri yemakemikari yezuva nezuva, kurima, kurima kwemvura nedzimwe nzvimbo. Kushandiswa kwakapararira kwePAC kunogona kukonzerwa nehunhu hwayo hwemakemikari hwakasiyana uye kushanduka-shanduka. Kugona kwayo kushanda sechinobatanidza, chinosimbisa, uye chinogadzirisa zvinoita kuti ive chishandiso chinokosha mumaindasitiri akasiyana-siyana. Sezvo tekinoroji nezvinodiwa nemaindasitiri zvichiramba zvichichinja, basa rePAC mukuzadzisa zvinodiwa izvi richasimbisa nzvimbo yayo sechikamu chakakosha mumaindasitiri akawanda.
