Aluminium chlorohydrate (ACH) uye polyaluminium chloride (PAC) inoita kunge maviri akasiyana makemikari makomisheni anoshandiswa seflocculants mukurapwa kwemvura. Muchokwadi, ACH inomira sechinhu chakanyanya kunyura mukati memhuri yePAC, ichiunza iyo yepamusoro alumina yemukati uye basicity inogoneka mune yakasimba mafomu kana yakagadzikana mhinduro mafomu. Iwo maviri ane maitiro akasiyana akati wandei, asi nzvimbo dzadzo dzekushandisa dzakasiyana zvakanyanya. Ichi chinyorwa chinokupa kunzwisisa kwakadzama kweACH nePAC kuitira kuti iwe ugone kusarudza chigadzirwa chakakodzera.
Polyaluminium chloride (PAC) ndeyepamusoro molecular polymer ine general chemical formula [Al2(OH)nCl6-n]m. Nekuda kwemaitiro ayo emakemikari akasiyana, ine huwandu hwakasiyana hwekushandisa munzvimbo dzakasiyana-siyana.Polyaluminium chloride (PAC) inoita basa rakakosha mukurapa kwemvura, inobudirira kubvisa zvakamiswa zvakasimba, colloidal substances, uye insoluble organic matter kuburikidza nekuita coagulation. Nekubvisa zvimedu, PAC inokurudzira kuunganidzwa, kufambisa kubviswa kwavo kubva mumvura. PAC, inowanzoshandiswa pamwe chete nemamwe makemikari sePAM, inosimudzira kunaka kwemvura, kuderedza turbidity, uye kusangana neindasitiri zviyero.
Muchikamu chekugadzira mapepa, PAC inoshanda senge inodhura-inoshanda flocculant uye precipitant, inovandudza marara etsvina uye rosin-neutral sizing. Iyo inowedzera saizi mhedzisiro, kudzivirira jira uye kusvibiswa kwehurongwa.
Zvikumbiro zvePAC zvinoenda kuindasitiri yezvicherwa, zvichibatsira mukugezesa ore nekuparadzanisa zvicherwa. Inoparadzanisa mvura kubva kune gangue, kufambisa kushandiswa zvakare, uye inobvisa tsvina.
Mukubvisa peturu nekunatsa, PAC inobvisa tsvina, insoluble organic matter, uye simbi kubva mumvura ine tsvina. Inobvisa uye inobvisa madonhwe emafuta, kudzikamisa matsime uye kudzivirira kukuvadzwa kwekuumbwa panguva yekuchera mafuta.
Kudhinda machira uye kudhaya kunobatsirwa kubva mukugona kwePAC kubata mvura yakaraswa nemavhoriyamu akakura uye yakakwira organic inosvibisa. PAC inosimudzira kusimba, nekukurumidza kugadzirisa kwemaruva alum, kuwana zvinoshamisa kurapwa.
ACH, Aluminium Chlorohydrate, ine molecular formula Al2(OH) 5Cl · 2H2O, inorganic polymer compound inoratidza dhigirii repamusoro re alkalization kana ichienzaniswa ne polyaluminium chloride uye inongotevera aruminiyamu hydroxide chete. Inopinda bhiriji polymerization kuburikidza nemapoka e-hydroxyl, zvichikonzera kuti molekuru ine nhamba yepamusoro yemapoka e-hydroxyl.
Inowanikwa mukurapa kwemvura uye yemazuva ese-kemikari mamakisi (yekushongedza giredhi), ACH inouya muhupfu (yakasimba) uye yemvura (solution) mafomu, ine yakasimba ichiva chena hupfu uye mhinduro imvura isina ruvara inopenya.
Iyo insoluble nyaya uye Fe yemukati yakaderera, saka inogona kushandiswa muzuva nezuva makemikari minda.
ACH inowana akasiyana maapplication. Inoshanda seyakagadzirwa zvigadzirwa zvemishonga uye yakasarudzika cosmetics, kunyanya seyekutanga antiperspirant musanganiswa inozivikanwa nekuita kwayo, kushomeka kushatirwa, uye kuchengeteka. Mukuwedzera, ACH inodhura uye naizvozvo haiwanzoshandiswa se flocculant mumvura yekunwa uye kushandiswa kwemvura yakasviba mumaindasitiri. ACH inoratidzawo kukwenenzverwa kunoshanda pane yakafara pH spectrum pane yakajairwa simbi munyu uye yakaderera-basin polyaluminum chlorides.
