【Ukusebenza】2,4,7,9-Tetramethyl-5-decyne-4,7-diol Umkhiqizo we-surfactant uyisengezo esisebenza ngezindlela eziningi esinezakhiwo zokumanzisa, ukususa amagwebu kanye nokuhlakaza. Umkhiqizo uyi-surfactant engeyona i-ionic ehambisanayo. Isakhiwo sawo esiyingqayizivele samakhemikhali e-gemini senza umkhiqizo unciphise ukungezwani kobuso, ulawule igwebu, futhi unciphise ukuzwela kwamanzi. Ungasetshenziswa ezimbonini eziningi: njengezembozo zezimboni ezisekelwe emanzini, upende wokhuni olusekelwe emanzini, upende wepulasitiki osekelwe emanzini, uyinki osekelwe emanzini, i-OPV, ingcina ezwela ukucindezeleka, ukukhiqizwa kwe-pigment kanye nodayi, imboni yokucubungula insimbi, i-flux, izibulala-zinambuzane, njll.
Ihamba ngokushesha, inciphisa ukucindezeleka kobuso obushintshashintshayo kanye nokucindezeleka kobuso obungaguquki, ikhipha amagwebu futhi ivimbele igwebu, inokuzwela okuphansi kwamanzi, ingamanzisa izinhlobo ezahlukene ze-substrate, ayikhi ama-micelles, izinzile kahle ekushiseni, futhi izinzile kahle kwi-acid-base. Izinhlelo ezisekelwe emanzini ezimanzisa zinamandla aphezulu okucindezeleka kobuso kunezinhlelo ze-solvent futhi zidinga ukwengeza ama-surfactants ukuze kuthuthukiswe ukumanzisa. Kodwa-ke, izinto zokumanzisa zendabuko zizobangela igwebu kanye negwebu elizinzayo. Uma kufakwa ama-defoamers, izinkinga zokumanzisa ezimbi njengemigodi emincane zizophinde zivele.
Kungagwema lezi zinkinga. Ukusebenza kungcono kakhulu kunezinhlayiya zendabuko, futhi kunganikeza ukucindezeleka okuphansi kakhulu kobuso kanye nokucindezela igwebu ngaphansi kwezimo eziguquguqukayo.
Ngenxa yesakhiwo sayo esiyingqayizivele sama-molecule, ukuxosha ama-surfactants ochungechunge lwento kuyi-ejenti enhle yokuxosha ama-non-ionic.
I-surfactant ayinayo indawo yamafu futhi ingaba nezakhiwo zokuhlanza ezihlala isikhathi eside ebangeni lokushisa elibanzi. Ukuzwela kwamanzi Ama-surfactant amaningi abangela izinkinga zokuzwela kwamanzi endaweni embozwe ngemuva kokomiswa.
Ama-surfactant athanda amanzi amaningi njenge-anionic (dioctyl sulfosuccinate sodium salt) noma ama-surfactant e-polyethoxylated aphinde ancibilike kalula emanzini, okubangela ukukhubazeka kobuso embozweni owomile, njengokunamathela, ubumhlophe bezinwele, ukufiphala, kanye nokumelana kwamanzi okungekuhle.
Kunconywa ukuthi kufakwe i-emulsion noma i-resin kanye nezinye izinto ezibangela ukusabalala kuqala, bese kufakwe izinto ezibangela ukusabalala okungu-2,4,7,9-Tetramethyl-5-decyne-4,7-diol series. Lokhu kuqinisekisa ukusabalala okuphezulu ohlelweni, okudinga ukusabalala okuphelele imizuzu eyi-15-30. Izinto ezibangela ukusabalala okungu-2,4,7,9-Tetramethyl-5-decyne-4,7-diol series zingase zikhanye ngesikhathi sokuthuthwa noma ukugcinwa emazingeni okushisa aphansi kakhulu; ukufudumala okuncane ngesikhathi sokusabalala okuncane kungazibuyisela kahle.
Izinga lokwengeza elinconyiwe SEBENZISA:
Ukugqoka okumanzi: 0.1%—3.0%
Izinamathiseli ezithinta umfutho wamanzi: 0.1%—1.0%
Isixazululo somthombo: 0.1%—1.0%
Uyinki wejethi: 0.1%—1.0%
Idatha engenhla iyinani elibonakalayo, futhi umthamo ofanele unqunywa uchungechunge lwezivivinyo
Izinzuzo:
Kusakazeka ngokushesha, kunciphisa ukucindezeleka kobuso obuguquguqukayo nobunganyakazi, kususa amagwebu, nokuzwela amanzi aphansi, kumanzisa ama-substrate ahlukahlukene ngaphandle kokwakha ama-micelles. Kuzinza okuhle kokushisa kanye nokumelana ne-acid-alkali.
Ukumanzisa:
Izinhlelo ezisekelwe emanzini zinokucindezeleka okuphezulu kobuso kunezinhlelo zokuxazulula izinkinga, futhi kuyadingeka ukwengeza i-surfactant ukuze kuthuthukiswe ukumanzi. Izinto zokumanzisa zendabuko zivame ukubangela izinkinga ze-foam kanye nokuqina. Imikhiqizo yochungechunge inganqoba lezi zinkinga, inikeze ukusebenza okuphezulu ekuhlinzekeni ukucindezeleka okuphansi kobuso kanye nokuhlanza ngisho nangaphansi kwezimo eziguquguqukayo.
Ukuhlambalaza:
Ama-surfactant achungechunge, anesakhiwo sawo esiyingqayizivele sama-molecule, asebenza njengezinto ezinhle kakhulu ezilinganayo zokususa ama-non-ionic defoaming. Abonisa izakhiwo eziqhubekayo zokususa ama-foaming ebangeni elikhulu lokushisa ngaphandle kwephuzu lokufiphala.
Ukuzwela kwamanzi:
Ama-surfactant amaningi abangela izinkinga zokuzwela kwamanzi endaweni eyomile. Ama-surfactant athanda amanzi amaningi njenge-anionic (dioctyl sulfosuccinate) noma ama-surfactant e-polyethoxylate ancibilika kalula emanzini, okubangela ukukhubazeka kobuso ezimbozweni ezomile njengokunamathela nokuba mhlophe, i-atomization, kanye nokumelana kwamanzi okungekuhle.
