Polyaluminium Chloride(PAC) yakakwira molecular polymer ine general kemikari formula Al2(OH)nCl6-nm. Nekuda kweiyo yakasarudzika makemikari ehupfumi, ine huwandu hwakawanda hwekushandisa munzvimbo dzakasiyana siyana. Ichi chinyorwa chinokutora iwe mukati memunda kuti udzidze mashandisirwo chaiwo ekomboni iyi.
Chekutanga, PAC inoongorora kurapwa kwemvura zvakanyanya. Inogona kunyatso kubvisa zvakaturikwa zvimedu, colloidal zvinhu, insoluble organic matter, uye kunyange zvidimbu zvakakura zvakanyanya mumvura. Izvi zvinowanikwa kuburikidza nehurongwa hunodaidzwa kuti coagulant, apo PAC inobata se coagulant. Inoderedza shongwe dzepamusoro, zvichiita kuti dziunganidzwe kuita zvidimbu zvakakura zvinokwanisa kuparadzaniswa nyore nyore kubva mumvura. Mhedzisiro yacho yakajeka, mvura yakachengeteka inosangana nemhando yemhando yemhando dzakasiyana dzemashandisirwo anodiwa, kusanganisira mvura yemuindasitiri. PAC inoshandiswawo mukuchenesa mvura nzira yekubvisa yakamiswa simbi uye kuvandudza kunaka kwemvura nekudzikisa turbidity. Inowanzoshandiswa pamwe chete nemamwe mishonga yekuchenesa mvura, yakadai sePAM, nezvimwewo, kuti uwane migumisiro yakanakisisa.
Polyaluminium chloride (PAC) inogona kushandiswa se flocculant muindasitiri yekugadzira mapepa kurapa tsvina uye mvura yakachena. PAC ine kuita kwepamusoro uye mutengo wakaderera, uye inofarirwa nevanogadzira mapepa. Pamusoro pezvo, inoshandawo senge precipitant, kuchengetedza uye sefa rubatsiro rwerosin-neutral saizi, iyo inogona kuvandudza saizi uye kudzivirira kusvibiswa kwemapepa muchina machira, mapepa ekugadzira slurries uye chena emvura masisitimu nezvigadzirwa zvehydrolyzate.
Polyaluminium chloride flocculants inoitawo zvakanaka muindasitiri yemigodhi. Inoshandiswa mukugezesa ores uye inoita basa rakakosha mukuparadzaniswa kwemaminerari. Kune rumwe rutivi, zvinonyatsoparadzanisa mvura kubva kune gangue kuitira kuti mvura ishandiswe zvakare; kune rumwe rutivi, inobvisawo mvura inogadzirwa sludge.
Muindasitiri yepetroleum, PAC zvakare inobata chinzvimbo chakakosha. Inoshandiswa kubvisa tsvina kubva mumafuta panguva yekuchera uye kucheneswa kwemafuta. Haisi chete inogona kunyatsobvisa insoluble organic matter, simbi nezvimwe zvinokuvadza mumvura yakaraswa, asi zvakare inobvisa uye inobvisa yakamiswa madonhwe emafuta kubva mumvura. Pakuchera matsime emafuta, PAC inobatsirawo kudzikamisa chitubu uye kudzivirira kukuvara kwekugadzira. Nekupinza mutsime, inopesana nekumanikidza kwekugadzira, kuderedza kukuvara kunogona kuitika. Izvi zvinokonzerwa nezvinhu zvePAC senge gelling agent uye tackifier.
Indasitiri yekudhinda uye yekudhaya inzvimbo yakakosha yekushandisa yePAC. Sezvo mvura yetsvina inogadzirwa neindasitiri iyi ine hunhu hwevhoriyamu yakakura, ruvara rwakadzama, uye nepamusoro pezvinhu zvinosvibisa organic, zvinova zvakaoma kurapa. Zvisinei, kuburikidza nekuita kwePAC, maruva e-alum panguva yekuchenesa mvura yakasviba yakasimba uye yakakura, inogadzirisa nokukurumidza, uye maitiro ekurapa anoshamisa.
Pamusoro peminda iri pamusoro, PAC inobatawo basa muindasitiri yemakemikari yemazuva ese, kurima, aquaculture nemamwe minda. Iko kushandiswa kwakapararira kwePAC kunogona kuverengerwa kune yakasarudzika makemikari zvimiro uye kuita kwakasiyana-siyana. Kugona kwayo kuita se coagulant, stabilizer, uye tackifier kunoita kuti ive chishandiso chakakosha mumaindasitiri akasiyana. Sezvo tekinoroji neindasitiri zvinodiwa zvichiramba zvichishanduka, basa rePAC mukuzadzisa izvi zvinodiwa richawedzera kusimbisa chinzvimbo chayo sechinhu chakakosha mumaitiro mazhinji emaindasitiri.
