Umkhuba wokuthuthuka wama-organic defoamers embonini yamaphepha. Ucwaningo lohlelo lokusebenza lwama-ejenti asebenzayo emhlabeni luyashintsha kusuka kohlobo olulodwa lwezinto eziningi kuya kohlobo oluyinhlanganisela. Amazwe emhlabeni jikelele abele inani elikhulu lokuphathwa kwabasebenzi nezimali kwizikhwama ezihlanganisiwe zobungcweti bama-organic defoamers. Ngokutshalwa kwezimali nezimpahla, imiphumela eminingi yokuphayona isitholakele, futhi ukusebenza okuphelele kwama-organic defoamers sekwenziwe ngcono kakhulu. Ubungcweti bokulungiselela okuphilayo kanye nokusetshenziswa kwayo kukhombisa ukuthambekela okujulile kokuthuthuka. Njengengxenye ebalulekile yomndeni ophilayo, ama-organic defoamers anomkhuba ofanayo wokuthuthuka embonini yephepha.

Njengoba sonke sazi, embonini yamaphepha esebenza kahle kakhulu emelwe yi-oleic acid amide, i-polyether, nezinto zokwakha, ama-organic defoamers asuse ngokuphelele izinhlobo ezingasebenzi kahle zendabuko kawoyela wamaminerali, uwoyela wemifino, utshwala, njll., Futhi banikele kakhulu embonini yamaphepha. Ngokuvamile, ama-polyether abicah defoamers aguqulwa asuka ekuqaleni okuhlukahlukene. Ama-defoamers ama-Silicone angasetshenziswa njengesisekelo sokuhlukanisa ama-polyether abicah defoamers. Ngokuya ngokwehluka kwabo, i-polyether silicone defoamers ingahlukaniswa ngohlobo lwe-polyol nohlobo lwe-fatty acid ester, okungukuthi, uhlobo lwe-amine ether. Lezi zinhlobo zama-defoamers zinezici zazo.

Isakhiwo samakhemikhali esihlaziywayo sehlukile kwamanye ama-organic defoamers. Amaqembu angacacisiwe ayafana nokusebenza okungasebenzi, futhi awanakho ukuhlangana nezakhi eziqukethe amanzi, amaqembu e-hydrocarbon noma amaqembu asebenzayo. Uma kuqhathaniswa namanye ama-organic silicon defoamers, anganciphisa amandla. Ukukhuthala, imvamisa kudinga ukwengeza isisindo se-molar esingu-1×10-6 ~ 75×I-10-6 iphethwe uhlelo ukuthola umphumela olindelekile wokudilizwa kwekhwalithi ephezulu.

Izakhiwo zomzimba zithambekele kumakhemikhali ajwayelekile, futhi akulula ukuba nokusabela okuxakayo ngama-foam compounds. Ama-organic defoamers anokumelana okuhle nokushisa nokumelana nokuhlolwa okuphezulu nokuphansi kokushisa. I-viscosity kawoyela we-methyl abicah ikhuphuka kancane kancane ibe ngu-200°C, futhi isibopho se-silicon-oxygen asincibiliki. Uwoyela we-methyl abicah unokuguquguquka okuhle kakhulu nokumanzi. Ngakho-ke, i-silicone defoamer inenzuzo yokuthuthukisa ikhwalithi yephepha elihlanganisiwe.

Ama-organic defoamers aphephile, akhiqizwa okuluhlaza, futhi enwetshiwe ngokomzimba. Le nhlanganisela yokukhiqiza emfashini futhi ehlakaniphile. Ama-organic defoamers anokulwa nokuguga, ukusebenza kwenqubo nezakhiwo zokulwa nokuguga. Zingasetshenziswa ngokugcwele ngaphansi kwawo wonke amazinga ezemvelo ngokwendawo. Ama-defoamers we-Organic aphezulu Ukusebenza kwekhwalithi yonke, kepha izindleko eziqondile ziphakeme. Ingasetshenziswa kuyo yonke inqubo yokukhiqiza embonini yamaphepha, ngokusebenza kahle okuphezulu kokudilizwa futhi kwesinye isikhathi kungagculisi umphumela wokucindezela amagwebu.

Ngakho-ke, i-organic defoamer ingahlanganiswa namanye ama-surfactants afana ne-oleic acid amide ne-polyether nge-demulsification kanye ne-foam suppression specificity yokwenza i-organic defoamer eyinhlanganisela, engagcini nje ngokuthuthukisa ikhono lobuchwepheshe lokucindezela amagwebu we-organic defoamer, kepha futhi Yehlisa izindleko eziqondile zezimpahla. Ngokuthuthuka kobungcweti bokuhlanganiswa okusebenza ngokuhlangana, ama-organic defoamers anamandla emakethe yohlelo lokusebenza ebanzi namandla amakhulu emakethe.
