Yintoni umahluko phakathi kweACH kunye nePAC?

I-Aluminiyam chlorohydrate (ACH) kunye ne-polyaluminium chloride (PAC) zibonakala ziyimichiza emibini eyahlukeneyo esetyenziswa njenge.iiflocculants kunyango lwamanzi. Ngapha koko, i-ACH ime njengeyona nto igxininisiweyo kusapho lwePAC, inikezela ngowona mxholo uphezulu we-alumina kunye nesiseko esifikelelekayo kwiifomu eziqinileyo okanye iifomu zesisombululo esizinzileyo. Ezi zimbini zineentsebenzo ezithile ezahlukileyo, kodwa iindawo zabo zesicelo zahluke kakhulu. Eli nqaku liza kukunika ukuqonda okunzulu kwe-ACH kunye ne-PAC ukuze ukwazi ukukhetha imveliso efanelekileyo.

Polyaluminium chloride

I-Polyaluminium chloride (PAC) yipolymer ephezulu yemolekyuli enefomula yekhemikhali jikelele [Al2(OH)nCl6-n]m. Ngenxa yeempawu zayo zeekhemikhali ezikhethekileyo, inoluhlu olubanzi lwezicelo kwiinkalo ezahlukeneyo.I-Polyaluminium chloride (PAC) idlala indima ebalulekileyo kunyango lwamanzi, ngokufanelekileyo ukuphelisa izinto eziqinileyo ezimisiweyo, izinto ze-colloidal, kunye ne-insoluble organic matter ngokusebenzisa iinkqubo zokudibanisa. Ngokunciphisa amasuntswana, iPAC ikhuthaza ukudityaniswa, iququzelela ukususwa kwawo emanzini. I-PAC, ehlala isetyenziswa ecaleni kwezinye iikhemikhali ezifana ne-PAM, iphucula umgangatho wamanzi, inciphisa i-turbidity, kunye nokuhlangabezana nemigangatho yoshishino.

Kwicandelo le-papermaking, i-PAC isebenza njenge-flocculant engabizi kakhulu kunye ne-precipitant, iphucula ukucocwa kwamanzi amdaka kunye ne-rosin-neutral sizing. Yongeza iziphumo zobungakanani, ikhusela ilaphu kunye nongcoliseko lwenkqubo.

Izicelo zePAC zinabela kushishino lwemigodi, ukuncedisa ekuhlanjweni kwentsimbi nokwahlulwa kwezimbiwa. Ikwahlula amanzi kwi-gange, yenza lula ukusetyenziswa kwakhona, kwaye ikhuphe i-sludge.

Ekutsalweni kwepetroleum kunye nokusulungekiswa, iPAC isusa ukungcola, izinto eziphilayo ezinganyibilikiyo, kunye nesinyithi emanzini amdaka. I-demulsifies kwaye isusa amathontsi e-oyile, ukuzinzisa ama-wellbores kunye nokuthintela umonakalo wokwakheka ngexesha lokugaya ioli.

Ushicilelo olulukiweyo kunye nokudaya luyazuza kwisakhono sePAC sokucoca amanzi amdaka ngomthamo omkhulu kunye nomxholo ophezulu wokungcoliseka kwendalo. I-PAC ikhuthaza ukuhlaliswa okuqinileyo, ngokukhawuleza kweentyatyambo ze-alum, ukuphumeza iziphumo eziphawulekayo zonyango.

IAluminiyam iChlorohydrate

I-ACH, i-Aluminiyam Chlorohydrate, kunye ne-molecular formula Al2 (OH) 5Cl · 2H2O, i-inorganic polymer compound ebonisa i-alkalization degree ephezulu xa kuthelekiswa ne-polyaluminium chloride kunye ne-trailing kuphela i-aluminium hydroxide. Idlula kwi-polymerization yebhulorho ngokusebenzisa amaqela e-hydroxyl, okukhokelela kwimolekyuli equlethe inani eliphezulu lamaqela e-hydroxyl.

Ifumaneka kunyango lwamanzi kunye nemigangatho yemihla ngemihla yekhemikhali (ibakala lokuthambisa), i-ACH iza ngomgubo (oluqilima) kunye neefom ezingamanzi (isisombululo), isiqina sibe ngumgubo omhlophe kunye nesisombululo silulwelo olungenambala olucacileyo.

Umbandela onganyibilikiyo kunye nomxholo we-Fe uphantsi, ngoko unokusetyenziswa kwiinkalo zemichiza yemihla ngemihla.

I-ACH ifumana usetyenziso olwahlukeneyo. Isebenza njengemathiriyeli ekrwada kumayeza kunye nezinto zokuthambisa ezikhethekileyo, ngakumbi njengeyona nto iphambili yokulwa nokurhawuka eyaziwa ngokusebenza kwayo, ukucaphuka okuphantsi, kunye nokhuseleko. Ukongeza, i-ACH iyabiza kwaye ke ngoko ayifane isetyenziswe njenge-flocculant kumanzi okusela kunye nokucocwa kwamanzi amdaka kwimizi-mveliso. I-ACH ikwabonisa ukunyuswa okusebenzayo kwi-pH spectrum ebanzi kuneetyuwa zentsimbi eziqhelekileyo kunye ne-low-basin polyaluminium chlorides.
