Ingabe i-Polyaluminum Chloride ingasetshenziswa ngemva kokuba imanzi? Nansi impendulo

Ithini I-Polyaluminum Chloride Ingabe Kufanele Usetshenziswe Ngemva Kokuba Nomswakama? Nansi Impendulo

I-Polyaluminum Chloride (PAC) iyi-flocculant esetshenziswa kakhulu e- Ukwelashwa Kwamanzi. Ivame ukuba nomswakama kanye nokugoqwa ngesikhathi sokugcina kanye nokuthuthwa. Ukuthi ingasetshenziswa yini kuncike ezingeni lomswakama, isimo sokugoqwa, kanye nokuthi yonakele yini.

1. Kungani Kuthambekele Ekubeni Nomswakama?

I-PAC iyinhlanganisela ye-polymer engaphili enokuthambekela okunamandla kokusebenzisa amanzi. Ama-molecule ayo aqukethe inani elikhulu lamaqembu e-hydroxyl, amunca kalula umswakama ovela emoyeni. Ukufaka i-cake kungenzeka kakhulu, ikakhulukazi ezindaweni ezinomswakama, lapho ukupakishwa konakele, noma lapho umoya ungena kahle.

2. Yiziphi izinguquko ezenzeka ngemva kokuba manzi?

1. Izinguquko Zomzimba: Uma kumanzi kancane, ubuso bezinhlayiya kuphela obuthambile futhi bunamathela, kuyilapho ingaphakathi lihlala lomile. Akukho phunga elingavamile noma ukushintsha kombala, futhi ukwakheka kwamakhemikhali kuhlala kungashintshi. Izinga lokuncibilika kuphela elithintekayo.
2. Izinguquko Zamakhemikhali: Uma kumanzi kakhulu, i-caking iba lukhuni. Isikhunta singakhula, kungase kube nephunga elingavamile, futhi umbala ungase ube mnyama. I-PAC idlula ku-hydrolysis kanye nokubola, okuholela ekunciphiseni kokuqukethwe kwe-aluminium esebenzayo, futhi umphumela we-flocculation uncishiswa kakhulu noma ulahleke.

3. Ungahlulela Kanjani Ukuthi Ingasetshenziswa Yini?

1. Hlola UkubukekaUma i-caking ikhululekile futhi ingachotshozwa ibe yimpuphu ngesandla ngaphandle kokuphazamiseka, ingasetshenziswa. Uma i-caking iqinile, ishintsha umbala, ikhunta, noma inephunga elingavamile, yonakele futhi ayinconywa ukuthi isetshenziswe.
2. Hlola Okuqukethwe KwengxenyeUma izimo zivuma, hlola okuqukethwe kwe-aluminium esebenzayo. Uma ihlangabezana nezindinganiso (isb., 28%, 30%), ingasetshenziswa; uma ingaphansi kuka-25%, kudingeka kuthathwe izinyathelo ezifanele.
3. Yenza Ukuhlolwa OkuncaneNgemva kokuncibilika, uma ikhambi lifana ngaphandle kwenani elikhulu lezinto ezingancibiliki futhi umphumela wokugoba uvamile, lingasetshenziswa; ngaphandle kwalokho, kufanele lilahlwe.

4. Izinyathelo Zokuqapha Zokusebenzisa (Uma Zingasetshenziswa)

1. Nweba isikhathi sokuxubha (imizuzu engama-30-60) ukuqinisekisa ukuthi kuncibilika ngokuphelele.
2. Ngokusho kwemiphumela yokuhlolwa kwesilinganiso esincane, khulisa umthamo ngokufanele ngo-10%-20%.
3. Yivale ngesikhathi bese uyigcina endaweni eyomile nengena umoya ukuze ugweme ukuswakama kwesibili.

5. Ungakuvimbela Kanjani Ukuswakama?

Khetha indawo yokugcina impahla eyomile nengena umoya enomswakama olawulwa ngaphansi kuka-60%; qiniseka ukuthi iphakheji iphelele; landela isimiso esithi "ukungena kuqala, ukuphuma kuqala" ukuze ugweme ukugcina isikhathi eside (impilo yeshelufu izinyanga ezingu-12); ungayigcini nezinto ezi-hygroscopic.

Isifinyezo

I-PAC emanzi kancane engakaboli ingasetshenziswa ngemuva kokwelashwa okufanele; i-PAC ebolile kakhulu kufanele ishintshwe. Isihluthulelo ukwahlulela isimo sayo ngokusebenzisa "ukuhlolwa kokubukeka + ukuhlolwa kwesikali esincane" nokwenza umsebenzi omuhle ekuvimbeleni umswakama ngesikhathi sokugcina ukuze kuncishiswe izinkinga ezivela emthonjeni.
