Ama-defoaming agents asetshenziswa ngokuvamile angahlukaniswa abe i-silicon (i-resin), ama-surfactants, i-alkane namafutha amaminerali ngokusho kwezingxenye ezahlukene.
1, ikilasi le-silicon (resin).
I-Silicone defoaming agent yaziwa nangokuthi i-emulsion type defoaming agent.Indlela yokusebenzisa iwukuba i-emulsify abicah nge-emulsifying agent (i-surfactant) futhi iyihlakaze emanzini bese iyifaka emanzini angcolile.I-silica powder ingolunye uhlobo lwe-silicon defoamer enomphumela ongcono wokuqeda ugwebu.
2, isigaba se-surfactant
Lolu hlobo lwe-ejenti yokukhipha amagwebu luyi-emulsifier empeleni, sebenzisa isenzo esihlakazayo se-ejenti esebenzayo engaphezulu okungukuthi, yenza izinto ezakha igwebu zigcina isimo se-emulsification esizinzile sihlakazeka emanzini, gwema ukukhiqiza igwebu ngalokho.
3. Opharafini
I-ejenti yokukhipha amagwebu kapharafini yenziwe nge-wax kapharafini kapharafini noma okuphuma kuyo ku-emulsified futhi kuhlakazwe i-emulsifying agent.Ukusetshenziswa kwayo kufana ne-emulsified defoaming agent ye-surfactant.
4. Amafutha amaminerali
I-mineral oil iwumshini wokuqeda ufofu oyinhloko.Ukuze kuthuthukiswe umphumela, ngezinye izikhathi kuhlanganiswe nensipho yensimbi, uwoyela we-silicone, i-silicon dioxide nezinye izinto ezisetshenziswa ndawonye.Ngaphezu kwalokho, ukuze wenze uwoyela wamaminerali kube lula ukusabalalisa ebusweni boketshezi olugwebulile, noma wenze insipho yensimbi ihlakazeke ngokulinganayo emafutheni amaminerali, ngezinye izikhathi futhi ingangeza ama-surfactants ahlukahlukene.
Izinzuzo kanye nokubi kwezinhlobo ezahlukene ze-ejenti yokukhipha amagwebu
Amafutha amaminerali, i-amide, utshwala obuphansi, i-fatty acid kanye ne-fatty acid ester, i-phosphate ester kanye nolunye ucwaningo lwe-organic defoaming agent kanye nesicelo ngaphambili, ingeyesizukulwane sokuqala se-ejenti yokukhipha amagwebu, inezinzuzo zokufinyelela kalula ezintweni zokusetshenziswa, ukusebenza okuphezulu kwemvelo. , izindleko zokukhiqiza eziphansi;Ububi bulele ekusebenzeni kahle kokukhipha amagwebu, ukucaciswa okuqinile nezimo zokusetshenziswa ezinokhahlo.
I-polyether antifoaming ejenti iyisizukulwane sesibili se-ejenti evimbela ugwebu, ikakhulukazi ehlanganisa i-polyether yeketango eliqondile, utshwala noma i-ammonia njenge-ejenti yokuqala ye-polyether, okuphuma kwe-polyether okuqiniswa yiqembu lesithathu letheminali.I-polyether defoaming agent iyinzuzo enkulu yekhono eliqinile lokuvimbela igwebu, ngaphezu kwalokho, kukhona i-polyether defoaming agent enokumelana nokushisa okuphezulu, ukumelana ne-asidi eqinile kanye ne-alkali nokunye ukusebenza okuhle kakhulu;Ukubi kunqunyelwe izinga lokushisa, inkambu yokusetshenziswa emincane, ikhono elimpofu lokukhipha amagwebu nezinga eliphansi lokuphuka kwebhamuza.
I-ejenti yokukhipha amagwebu ye-Silicone (isizukulwane sesithathu se-ejenti yokukhipha amagwebu) inamandla okukhipha amagwebu okuqinile, amandla okukhipha amagwebu ngokushesha, ukuguquguquka okuphansi, okungeyona into enobuthi emvelweni, ayikho inertia yokuphila, ukusetshenziswa okubanzi nezinye izinzuzo, ngakho-ke inamathemba abanzi okusebenza kanye nokukhulu. amandla emakethe, kodwa ukusebenza kokuvimbela ukukhihliza amagwebu kubi.
I-polyether modified polysiloxane defoaming agent inezinzuzo ze-polyether defoaming agent kanye ne-silicone defoaming ejenti ngesikhathi esifanayo, okuyisiqondiso sokuthuthukiswa kwe-ejenti yokukhipha amagwebu.Kwesinye isikhathi ingasetshenziswa futhi ngokuya ngokuncibilika kwayo okuphambene, kodwa okwamanje kunezinhlobo ezimbalwa zama-ejenti akhipha amagwebu anjalo, asesesigabeni socwaningo nentuthuko, futhi izindleko zokukhiqiza ziphezulu.
