1 Ukunganyibiliki kahle noma ukuncibilika kabi oketshezini olunegwebu kusho ukuthi igwebu liphukile, futhii-defoamerkufanele igxilwe futhi igxile kwifilimu ye-foam. Ukuze i-defoamer, kufanele igxilwe futhi igxilwe ngokushesha, futhi i-defoamer, kufanele ihlale igcinwe kulesi simo.
Ngakho-ke, i-defoamer isesimweni sokugcwala ngokweqile oketshezini olunegwebu, futhi kulula ukufinyelela esimweni esigcwele kakhulu kuphela uma ingancibiliki noma ingancibiliki kahle. Ayinakuncibilika noma ayincibiliki kahle, kulula ukuqoqa esixhumi esibonakalayo segesi-uketshezi, kulula ukugxila efilimini yegwebu, futhi ingadlala indima ekugxilweni okuphansi. Kuma-defoam asetshenziswa ezinhlelweni zamanzi, ama-molecule ezithako ezisebenzayo kufanele abe yi-hydrophobic enamandla futhi abe ne-hydrophilic ebuthaka, futhi inani le-HLB kufanele libe kububanzi obungu-1.5-3 ukuze lisebenze kahle kakhulu.
2 Ukushuba kwamanzi kungaphansi kunoketshezi olugwebu. Kuphela lapho amandla e-intermolecular e-defoamer amancane futhi ukungezwani kwendawo kuphansi kunoketshezi olugwebu, lapho izinhlayiya ze-defoamer zingacwiliswa futhi zandiswe kwifilimu yegwebu. Kuyaphawuleka ukuthi ukungezwani okungaphezulu koketshezi olugwebulile akukona ukungezwani okungaphezulu kwesixazululo, kodwa ukungezwani okungaphezulu kwesixazululo esinegwebu.
3. Izinga elithile lokuhlobana noketshezi olugwebuzelayo. Njengoba inqubo yokukhipha amagwebu empeleni ingumncintiswano phakathi kwejubane lokuwa kwegwebu kanye nesivinini sokukhiqizwa kwegwebu, i-defoamer kufanele ikwazi ukuhlakaza ngokushesha oketshezini olunamagwebu ukuze ikwazi ukudlala indima ngokushesha ebangeni elibanzi loketshezi olugwebulile. Ukwenza i-defoamer isakazeke ngokushesha, izithako ezisebenzayo ze-defoamer kumele zibe nezinga elithile lokuhlobana noketshezi olugwebu. Uma izithako ezisebenzayo ze-defoamer ziseduze kakhulu noketshezi olugwebu, zizohlakazeka; uma zikude kakhulu, kuzoba nzima ukuzihlakaza. Kuphela uma ukuhambisana kufanelekile, umphumela uzoba muhle.
4. Akukho ukusabela kwamakhemikhali ngoketshezi olugwebulayo. I-defoamer isabela noketshezi olugwebulile. Ngakolunye uhlangothi, i-defoamer izolahlekelwa umphumela wayo, futhi ngakolunye uhlangothi, izinto eziyingozi zingase zikhiqizwe, ezithinta ukukhula kwama-microorganisms.
5. Ukuguquguquka okuphansi nesikhathi eside sesenzo. Okokuqala, thola uhlelo lapho i-defoamer idinga ukusetshenziswa khona, kungakhathaliseki ukuthi uhlelo olusekelwe emanzini noma uhlelo olusekelwe kuwoyela. Isibonelo, embonini yokuvutshelwa, ama-defoam asekelwe ngamafutha afanaI-polyether-modified silicone noma i-polyether kufanele isetshenziswe. Imboni yokugqoka esekelwe emanzini kufanele isebenzise ama-defoamers asekelwe emanzini kanye nama-silicone defoamers. Khetha i-defoamer, qhathanisa inani elingeziwe, bese ubhekisela enanini ukuze uthole umkhiqizo we-defoamer ofaneleka kakhulu futhi ukonga.
