Ingabe I-Polyaluminium Chloride Ingasetshenziswa Ngemva Kokuba Nomswakama? Nansi Impendulo

Angakwazi I-Polyaluminium Chloride Ingabe Ingasetshenziswa Ngemva Kokuthola Umswakama? Nansi Impendulo

I-Polyaluminium Chloride (PAC) iyi-flocculant evame ukusetshenziswa ngaphakathi Ukwelapha Amanzi. Ijwayele ukuba nomswakama kanye ne-caking ngesikhathi sokugcinwa nokuhamba. Ukuthi ingasetshenziswa yini kuya ngezinga lokuswakama, isimo sekhekhe, nokuthi isiwohlokile yini.

1. Kungani Kujwayele Ukuba Nomswakama?

I-PAC iyinhlanganisela ye-polymer engaphili ene-hydrophilicity eqinile. Ama-molecule ayo aqukethe inani elikhulu lamaqembu e-hydroxyl, athatha kalula umswakama emoyeni. Ikhekhe livame ukwenzeka, ikakhulukazi ezindaweni ezinomswakama, lapho ukupakishwa konakalisiwe, noma lapho umoya ungangeni kahle.

2. Yiziphi Izinguquko Ezenzeka Ngemva Kokuba Dampness?

1. Izinguquko Emzimbeni: Uma kunomswakama kancane, ingaphezulu kuphela lezinhlayiya liyathambisa futhi linamathele, kuyilapho ingaphakathi lihlala lomile. Alikho iphunga elingavamile noma ukuguquguquka kombala, futhi ukwakheka kwamakhemikhali kuhlala kungashintshile. Izinga lokuqedwa kuphela elithintekayo.
2. Izinguquko Zekhemikhali: Uma kunomswakama kakhulu, ikhekhe liba lukhuni. Isikhunta singakhula, kungase kube nephunga elingavamile, nombala ungase ube mnyama. I-PAC ithola i-hydrolysis kanye nokubola, okuholela ekwehleni kokuqukethwe kwe-aluminium esebenzayo, futhi umphumela we-flocculation uyancipha kakhulu noma ulahlekile.

3. Indlela Yokwahlulela Ukuthi Ingasetshenziswa?

1. Hlola Ukubukeka: Uma ikhekhe lixega futhi lingachotshozwa libe yimpushana ngesandla ngaphandle kokungajwayelekile, lingasetshenziswa. Uma ikhekhe liqinile, liguqukile, likhuntile, noma linephunga elingajwayelekile, seliwohlokile futhi alinconywa ukuthi lisetshenziswe.
2. Hlola Okuqukethwe Kwengxenye: Uma izimo zivuma, hlola okuqukethwe kwe-aluminium esebenzayo. Uma ihlangabezana nezinga (isb, 28%, 30%), ingasetshenziswa; uma ingaphansi kuka-25%, izinyathelo ezifanele kufanele zithathwe.
3. Yenza Ukuhlolwa Kwezinga Elincane: Ngemuva kokuqedwa, uma isisombululo sifana nenani elikhulu lezinto ezingancibiliki futhi umphumela we-flocculation ujwayelekile, ungasetshenziswa; kungenjalo, kufanele ilahlwe.

4. Izinyathelo Zokusebenzisa (Uma Zisebenziseka)

1. Nweba isikhathi sokugqugquzela (imizuzu engama-30-60) ukuze uqinisekise ukuqedwa okuphelele.
2. Ngokwemiphumela yokuhlolwa kwezinga elincane, ngokufanelekile ukwandisa umthamo ngo-10% -20%.
3. Yivale ngesikhathi futhi uyigcine endaweni eyomile futhi engenawo umoya ukuze ugweme umswakama wesibili.

5. Indlela Yokuvimbela Umswakama?

Khetha indawo yokugcina impahla eyomile nengena umoya enomswakama ongaphansi kuka-60%; qinisekisa ukuthi iphakheji iphelele; landela isimiso "sokuqala sokungena, sokuqala" ukuze ugweme ukugcina isikhathi eside (impilo yeshalofu yizinyanga ezingu-12); ungayigcini nezinto ze-hygroscopic.

Isifinyezo

I-PAC enomswakama kancane engonakalanga ingasetshenziswa ngemva kokwelashwa okufanele; I-PAC enamakhekhe anzima futhi eyonakele kufanele ishintshwe. Isihluthulelo ukwahlulela isimo saso ngokusebenzisa "ukuhlolwa kokubukeka + ukuhlolwa okuncane" futhi wenze umsebenzi omuhle ekuvimbeleni umswakama ngesikhathi sokugcina ukunciphisa izinkinga ezivela emthonjeni.
