Embonini kashukela, ukukhiqizwa kwegwebu kuyinto evamile. Igwebu lithinta izigaba ezahlukene zokukhiqizwa kukashukela, kusukela ekucwengisisweni kwejusi kanye nokuhluzwa kuya ekuhwamukeni nasekuqineni. Igwebu lingathinta kokubili isivuno kanye nekhwalithi kashukela.kuyasebenzaAma-Antifoaming Ejentikubalulekile ekugcineni ukuqina kwenqubo nokuqinisekisa ikhwalithi kashukela ehambisanayo.
Izimbangela Zokwakheka Kwegwebu Ngesikhathi Sokukhiqizwa Koshukela
- Ama-surfactant emvelo kumoba
- Ukuba khona kwama-wax, amaprotheni, kanye namakhemikhali e-organic
- Ukuxuba ngomshini ngesikhathi sokukhipha kanye nezinqubo zokucacisa
- Inqubo yokuhwamuka kokushisa okuphezulu
Uma igwebu lakheka phezu koketshezi, lidala ifilimu encane enciphisa ukusebenza kahle kokukhiqiza. Lokhu kuholela ekunciphiseni isivuno kanye nezindleko ezengeziwe. Ngaphezu kwalokho, igwebu lingabangela nokuchitheka, okuholela ekulahlekelweni komkhiqizo obalulekile.
Izimbangela Zokwakheka Kwegwebu Ngesikhathi Sokukhiqizwa Koshukela
Ama-antifoam kanye nama-defoam agents asetshenziswa ukubhekana nezinkinga ezishiwo ngenhla. Lezi zixazululo zingangezwa koketshezi ukuze kuncishiswe ukucindezeleka kobuso, ngaleyo ndlela kuvinjelwe ukwakheka kwe-foam. Uma i-foam isivele yakhekile, ama-defoam agents angangezwa ukuze kuqhekeke i-foam futhi kuvinjelwe ukuthi ingabangela izinkinga ezengeziwe.
• Ukukhipha Nokucacisa Ijusi
Ijusi likamoba liqukethe ukungcola okukhiqiza igwebu kalula ngesikhathi sokucindezela. Ukwengeza izinto ezilwa nokuvuvukala kusiza ukunciphisa igwebu ngokuthi:
Ukwehlisa ukungezwani kobuso
Ukuthuthukisa ukuthuthwa kwenhlabathi
Ukwandisa ukusebenza kahle kokucacisa
Lokhu kuphumela ekukhanyeni okucacile kanye nemiphumela engcono yokucubungula okulandelayo.
• Ukuhwamuka kanye nokuhlushwa
Ukuqongelela kwegwebu ngaphakathi kwama-evaporator kungaholela ku:
Ukunciphisa ukusebenza kahle kokudlulisa ukushisa
Okubangela ukuvaleka komoya
Okuholela ekuphazamisekeni kokukhiqiza
Izinto eziqinile, ezingashisi ukushisa ezivimbela ukugqwala ziqinisekisa ukubila okuqhubekayo futhi zivimbela ukugcwala kwamanzi.
• Ukwakheka kwekristalu
Igwebu elikhiqizwa ngesikhathi sokwakheka kwekristalu lithinta ukukhula kwekristalu. Inani elifanele le-antifoaming agent:
Iqinisekisa ukwakheka kwekristalu okufanayo
Kuvimbela ukukala kanye nekhwalithi kashukela engalingani
• Ukwelashwa Kwamanzi Angcolile
Amanzi angcolile asezigayweni zikashukela nawo akhiqiza igwebu ngesikhathi sokufaka umoya noma ukuxubha. Ukusebenzisa ama-antifoaming agents asezingeni lamanzi angcolile kungathuthukisa:
Ukusebenza kahle kokwelashwa kwezinto eziphilayo
Ukuthuthwa kodaka
Ukusebenza kahle kwezitshalo sekukonke
Izinzuzo Zokusebenzisa Ama-Defoamers Enqubweni Yokwenza Ushukela
Ukusebenza kahle kokucubungula okuphezulu
Ama-defoamer angathuthukisa ukusebenza kwemishini, anciphise isikhathi sokungasebenzi, futhi alondoloze ukuzinza kwemigqa yokukhiqiza.
Nciphisa ukulahleka komkhiqizo
Ukunciphisa ukuchichima kanye nokulawula kangcono igwebu kungavimbela ukulahleka kukashukela ngesikhathi sezinqubo zokuhwamuka kanye nokuhlunga.
Ukusebenza okungcono kokudlulisa ukushisa
Ama-defoamers angasusa ungqimba lwe-foam oluvimbela ukushintshaniswa kokushisa, ngaleyo ndlela athuthukise ukusebenza kahle kwamandla.
Ukuthuthukiswa kwekhwalithi yomkhiqizo
Inqubo yokubilisa eqinile kanye neyokwenza i-crystallization ingaqinisekisa ukuthi umbala kanye nobumsulwa bukashukela kuhlala kufana.
Nciphisa izindleko zokusebenza
Ukunciphisa imvamisa yokuhlanza, ukunciphisa isikhathi sokungasebenzi, kanye nokwandisa isikhathi sokusebenza kwemishini kungasiza ekwehliseni izindleko.
Indlela Yokukhetha I-Defoamer Efanele Yefektri Yakho Kashukela
Lapho ukhetha i-defoamer, izici ezifana nezithako ezisebenzayo, ukuphepha kokudla, ukusebenza kwe-defoamer kanye nokusebenza kwayo kudingeka zicatshangelwe.
Isidingo sama-defoamers ekuxhumaneni kwezinqubo ezahlukene
Ukucindezela nokuhlanza ijusi likamoba
Kuyadingeka:
Ukuhlanza okusheshayo kanye nokulwa nokukhipha amagwebu
Iyahambisana nezicacisi (i-PAC, i-PAM, i-lime, njll.)
Akukuthinti ijubane lokuthuthwa kwenhlabathi
Uhlelo lokuhwamuka
Izinto ezibalulekile okufanele uzicabangele:
Imelana nokushisa okuphezulu (>100℃)
Akukuthinti ukusebenza kahle kokushintshana kokushisa
Ayihlanganisi uwoyela noma ayintanti ngaphansi kwezimo zokuqukethwe okuqinile okuphezulu
Kulesi sigaba, ama-defoamer asekelwe ku-silicon avame ukusebenza kahle kakhulu.
Isigaba se-Crystallization
Isidingo
Ukuhlanza okuzinzile ngaphandle kokuthinta ukukhula kwekristalu
Akubangeli ukungcola kumkhiqizo noma kuthinte umbala kashukela
Kungakhethwa ama-defoamer okudla ahlanzekile kakhulu.
Ukwelashwa kwamanzi angcolile ezimbonini zikashukela
Kungakhethwa uwoyela wamaminerali noma ama-polyether defoamer angabizi kakhulu, afanelekela amathangi okungenisa umoya kanye namathangi okuxuba.
Khetha uhlobo olufanele lwe-defoamer ngokusekelwe ezidingweni zokukhiqiza
| Uhlobo Lokulwa Negwebu | Inqubo Esebenzayo | Izinzuzo Eziyinhloko | Amanothi / Izinto Okufanele Uzicabangele |
| I-Silicone Antifoam | Izinqubo zokuhwamuka, ukubila, nokushisa okuphezulu | - Ukuhlambulula okusheshayo - Ayimelani nokushisa - Isilinganiso esiphansi, esisebenzisa kahle imali - Izinzile endaweni enosawoti omningi futhi ephezulu-izimo eziqinile | - Sebenzisa ama-pructs asezingeni lokudla ukuze uthinte ngqo ijusi likashukela |
| I-Antifoam Yezinga Lokudla (E900) | Ukukhishwa kwejusi, ukucaciswa, i-carbonation, i-crystallization | - Ihambisana nemithethonqubo yokudla ye-FDA/EU - Kuphephile ukuthintana nokudla - Akukuthinti ikhwalithi kashukela | - Ngokuvamile izindleko ziphakeme kunemikhiqizo yezinga lezimboni |
| I-Antifoam Esekelwe Kuwoyela Wezimbiwa | Ukwelashwa kwamanzi amdaka, amathangi okungenisa umoya, amathangi okuxuba | - Izindleko eziphansi - Ukucindezela igwebu okuzinzile - Kufanelekela okungewona ukudlaizigaba zokuxhumana | - Akufaneleki ezinqubweni zokuthintana nokudla ngqo |
| I-Polyether Antifoam | Ama-evaporator, isiraphu kashukela enokushisa okuphezulu/enamandla aphezulu | - Ihlala isikhathi eside ekushiseni - Ukucindezela igwebu okuhlala isikhathi eside - Isebenza kahle ezinhlelweni ezinamazinga aphezulu okugcwala | - Kudinga ukuhlolwa kwendawo ukuze kutholakale ukuhambisana kwenqubo |
Izinkomba ezibalulekile zokukhetha i-defoamer
Lapho ukhetha ama-defoamers, izinkomba ezilandelayo kufanele zinikezwe ukunakwa okukhethekile:
Isivinini sokudukisa
Phula amabhamuza ngokushesha ukuze uvimbele ukugcwala kanye nokuphazamiseka kokukhiqiza.
Umphumela wokulwa nogwebu ohlala isikhathi eside
Ama-defoaming kudingeka alondoloze imiphumela yokulwa namagwebu ehlala isikhathi eside ngaphansi kwezimo zokushisa okuphezulu kanye nezimo zokugunda okuphezulu.
Ukusebenza kokumelana nokushisa okuphezulu
Ikakhulukazi esigabeni sokuhwamuka, lapho izinga lokushisa kufanele lidlule ku-110℃.
Ukuphepha komkhiqizo
Kumelwe kukhethwe ama-defoamer asezingeni lokudla esigabeni sokuxhumana kokudla.
Ukuhambisana namanye amakhemikhali
I-ejenti yokucacisa
I-Flocculant
Isilinganiso selamula
Akufanele kuthinte ukuqina kwejusi kashukela
Umthelela ekhwalithini yomkhiqizo
Akufanele kuthinte umbala kashukela, usayizi wezinhlamvu noma ubumsulwa.
Izindleko zokusebenzisa
Ukusebenza kahle kwemikhiqizo kufanele kuhlolwe kusukela "ezindleko ngokusetshenziswa ngakunye" kuya "ezindleko zokuhlanza izicubu ngethani likashukela".
Iziqondiso Zesilinganiso Esinconywayo Sama-Defoamers Embonini Kashukela
Amanani athile angahluka kuye ngekhwalithi kashukela kanye nezimo zokucubungula.
Ukucaciswa kwejusi: 10-50 ppm
Ukuhwamuka: 5-30 ppm
Ukwakheka kwekristalu: 5-20 ppm
Ukwelashwa kwamanzi angcolile: 10-100 ppm
Qala ngokuhlolwa okuncane bese wenza ngcono umthamo ngokusekelwe emiphumeleni yokuhlolwa endaweni.
Ngokulawula igwebu ezigabeni ezahlukene zokucubungula, amabhizinisi akhiqiza ushukela angakhulisa ukukhiqizwa, aqinisekise ikhwalithi yomkhiqizo ezinzile futhi anciphise izinkinga zokusebenza. Ukukhethwa kwe-defoamer efanele, kungakhathaliseki ukuthi isekelwe ku-silicon, isekelwe ku-oyela wamaminerali noma izinga lokudla, kuzoba nomthelela omkhulu ekusebenzeni kokukhiqiza kanye nezindleko zokukhiqiza zizonke.
Ulwazi olwengeziwe mayelana nemboni kashukela lungatholakala ku-"Izixazululo Zamakhemikhali Zemboni Kashukela". Ngethemba ukuthi lokhu kuzokusiza."
