Ekuhlanzeni kwezimboni, igwebu alithinti nje kuphela ukungcola, kodwa futhi kunzima ukulihlanza, livame ukuba nezinsalela, futhi lingaze ligcwale imishini yokuhlanza, okubangela imfucuza. Ngaphezu kwalokho, igwebu lingathwala ama-surfactants esigabeni soketshezi lokuhlanza. Ngakho-ke, kubalulekile ukusebenzisa imikhiqizo yokuhlanza enegwebu eliphansi ukuze kutholakale imiphumela emihle yokuhlanza.
Ukukhiqizwa kanye nokuqina kwe-foam ekuhlanzeni kwezimboni kuthonywa izici ezahlukahlukene, njengokwakheka kwama-surfactants, ezinye izingxenye ezixazululweni zokuhlanza, i-acidity-alkalinity kanye nama-electrolyte, izinga lokushisa, ubulukhuni bamanzi, amabala kawoyela, kanye nezindlela zokuhlanza. Ngakho-ke, ama-surfactants ane-foam ephansi abhekisela kuma-surfactants angakhiqizi i-foam ngaphansi kwezimo zokusetshenziswa, noma ane-foam engazinzile futhi enganyamalala ngokushesha.
Izici Zokusebenza Kwama-Surfactants Anegwebu Eliphansi
Ukumelana ne-asidi/alkali: Ngaphansi kwezimo ezijwayelekile, zingabhekwa njengezimelana ne-asidi/alkali, ikakhulukazi ama-ether e-alcohol ane-alkali, angahlala ezinzile isikhathi eside ngaphansi kwezimo zokushisa okuphezulu kanye nezimo ze-asidi/alkali ephezulu (isakhiwo sawo ngeke sishintshe). Umsebenzi womphezulu: Ngenxa yomkhawulo wesakhiwo sama-molecule, umehluko we-polarity phakathi kweqembu le-hydrophilic kanye neqembu le-lipophilic esakhiweni se-amphiphilic se-surfactant uncishiswe kakhulu. Ukunciphisa iphuzu lamafu: Ngenxa yamaqembu e-lipophilic akhuphukile esakhiweni, iphuzu lamafu lama-surfactants angewona ama-ionic aphansi liphansi kakhulu. Ukwehla kwephuzu lokuqandisa: Njengoba ukuphela kwe-hydrophilic kuvinjiwe amaqembu e-lipophilic noma e-lipophilic, amandla e-intermolecular ayabuthakathaka, okuholela ekwehleni kwephuzu lokuqandisa lomkhiqizo. Lesi sici senza kube lula ukusetshenziswa kwemikhiqizo enjalo. Ukuncipha kokuthambekela kwejeli: Ukuthambekela kwemikhiqizo enjalo kokwenza amajeli emanzini kuncishiswe kakhulu, okuzuzisa kakhulu ekulungiseleleni umkhiqizo.
Ukusetshenziswa kwama-surfactants aphansi kwe-foam ekuhlanzeni kwezimboni
Ukuhlanzwa komshini wokuwasha izitsha: Ngokuvamile, kubhekisela ezitsheni zokuwasha ngaphambi kokungena emshinini wokuwasha izitsha. Ukuhlanzwa ngaphakathi: Kubhekisela kakhulu ekuhlanzeni ngesikhathi senqubo yokukhiqizwa kokudla kanye nokucubungula. Enqubweni yokuhlanza, indima eyinhloko yama-surfactants ukumanzisa. Ngesikhathi esifanayo, ama-surfactants emikhiqizweni yokuhlanza angama-surfactants akhipha amagwebu aphansi, anemiphumela yokususa amagwebu kanye nokuvimbela igwebu futhi angaqinisekisa inqubekela phambili ebushelelezi yokuhlanza. Ukuhlanzwa kwamabhodlela eziphuzo asetshenzisiwe: Kuhilela kakhulu ukuhlanzwa kwamabhodlela kabhiya asetshenzisiwe. Ukuhlanzwa kwensimbi: Ekuhlanzeni insimbi, ngaphezu kokumanzisa, ukususa amagwebu kanye nokuvimbela igwebu, ama-surfactants kumele abe nemiphumela enamandla yokususa amagwebu. Ngaphezu kwalokho, njengoba ukuhlanza kuqhubeka, amagwebu kawoyela angabangela ukwanda kwegwebu ohlelweni, ngakho-ke ama-surfactants kudingeka abe nezakhiwo ezinhle zokususa amagwebu. Ngesikhathi esifanayo, akufanele nje azikhiphe amagwebu aphansi kodwa futhi abe nekhono lokuvimbela igwebu elibangelwa amagwebu kawoyela.
