Embonini, uma inkinga yegwebu ingathathi indlela efanele, kuyoba nzima kakhulu ukubhekana nayo, khona-ke ungazamai-ejenti yokukhipha amagwebungokukhipha amagwebu, akukhona nje ukusebenza okulula, kodwa futhi umphumela uyabonakala.Okulandelayo, ake sijule phakathiAma-Silicone Defoamersukuze ubone ukuthi mingaki imininingwane ongayinakile.
Ngesikhathi sokukhiqiza nokusetshenziswa kwezingubo zokugqoka, izinkinga ze-foam zivame ukuvela.Uma amasheya engaqediwe ngesikhathi, i-fluidity ye-coating izothinteka, okubangela ukukhubazeka okungaphezulu, ukungalingani, nokuqhekeka ngesikhathi sokubunjwa kwefilimu, okuzogcina kuholele ekukhuphukeni kwezindleko zokukhiqiza., ngakho-ke kufanele sisebenzise indlela engabizi kakhulu ukuxazulula le nkinga ukuze sibuyise ukulahlekelwa.
Kunezinhlobo eziningi zama-defoamers, okuhlanganisa uwoyela wamaminerali, i-silicone, ne-polyether, njll., anezinzuzo eziningi njengokuzikhandla, ukusabalalisa kalula, ukuguquguquka okunamandla, ukuqeda amagwebu okuhle, nokucindezelwa kwegwebu okuhlala isikhathi eside.Konke kukodwa, ngeke kuthinte izakhiwo zokwenza ifilimu ngemuva kokusetshenziswa, futhi ngeke kubangele amaphutha ebusweni bopende, ikakhulukazi kumasistimu okupenda asekelwe emanzini.
Inani le-ejenti yokukhipha amagwebu lincane kakhulu, inkulungwane eyodwa kuya kwezintathu kuphela ezingakwazi ukufeza umphumela ocacile wokuqeda amagwebu, ngakho-ke isetshenziswa kabanzi emigqonyeni esekwe emanzini, oyinki, oyinki, ovanishi, amafutha onqenqema lesikhumba, ukwenza iphepha, ukunamathela, i-laminating glue, latex. upende, izinto zokunamathisela nezinye izinkambu.
Njengamanje, ngenkinga yegwebu, izindlela ezintathu ezilandelayo zivame ukusetshenziselwa ukukhipha amagwebu.
1. Indlela yokukhipha amagwebu ngomshini
I-Mechanical defoaming ngokuvamile isetshenziswa ezimweni lapho ukushisa kuyadingeka ukuze kubangele ukuwohloka komkhiqizo nokuhlukaniswa kwegwebu, njengokushintshwa kwengcindezi esheshayo, ukuhlukaniswa kwe-centrifugal kwezixazululo namagwebu, ukufafaza izinhlelo zegwebu ngomoya ocindezelweyo, ukuhlunga kwe-ultrasonic, njll.
2. Indlela yokukhipha amagwebu ngokomzimba
Ngokuvamile, ukukhipha amagwebu emzimbeni kusebenzisa indlela yokuguqula izinga lokushisa libe yi-defoam futhi licindezele igwebu.Njengoba izinga lokushisa likhuphuka, i-viscosity yesisombululo iyancipha futhi i-solvent iyahwamuka, ibangele ukugoqa kwegwebu.Lapho izinga lokushisa liyancipha, ukunwebeka kwe-foam kuncipha, futhi izinga lokushisa eliphansi libangela uqweqwe lweqhwa, okuphazamisa ukwakheka kwegwebu futhi kubangele ukuqhuma kwegwebu.
3. Indlela yokukhipha amagwebu ngamakhemikhali
Indlela yokukhipha amagwebu ngamakhemikhali ikakhulukazi incike ekwengezweni kwe-silicone defoaming agent, okuyindlela elula nephumelelayo yokukhipha amagwebu ne-antifoaming phakathi kwezindlela ezintathu.Kuncike kakhulu ekuguquleni inani le-pH, ukukhipha usawoti, nokushintsha ukusabela kwamakhemikhali egwebu.Isimiso siwukuthi ngemva kokuba i-ejenti yokukhipha amagwebu yengezwe ku-ejenti yokukhipha amagwebu, ama-athomu akhipha amagwebu azosatshalaliswa ngokungahleliwe ebusweni boketshezi, asakazwe ngokushesha, futhi akhe ifilimu elincane elinezingqimba ezimbili, elizoqhubeka lisakaza, lingene, futhi. zihlasele zibe izingqimba, kancane kancane Faka esikhundleni udonga oluncane lwegwebu lokuqala, uvimbele ukwakheka kwefilimu enwebekayo, ucekele phansi ikhono lokuziphilisa legwebu, wenze igwebu liqhume.
Ngokwezimo ezihlukene kanye nezidingo ezihlukene zokukhipha amagwebu, khetha indlela yokukhipha amagwebu ne-ejenti yokukhipha amagwebu ekufanele.Singakunikeza i-defoamer ekufanele kakhulu, wamukelekile ukuyithenga.
