Ukusetshenziswa kwama-Surfactants aphansi ekuhlanzeni kwezimboni
Ekuhlanzeni kwezimboni, igwebu aligcini nje ngokuphazamisa ukuhlanza kodwa futhi lenza ukuhlanza kube nzima, kuvame ukushiya izinsalela, futhi kungaze kugcwale imishini yokuhlanza, okuholela emfucumfucwini. Ngaphezu kwalokho, igwebu lingasusa ama-surfactants esigabeni soketshezi lokuhlanza. Ngakho-ke, imikhiqizo yokuhlanza enegwebu eliphansi...Funda kabanzi -
Ukubonakaliswa kokungazinzi kwe-emulsions (ukugoqeka, ukuhlangana, ukuhlukaniswa kanye nokususwa kwe-mulsification)
Kunezibonakaliso eziningana zokungazinzi kwe-emulsion: ukugoba, ukuhlangana, ukuhlukaniswa (noma ukusatshalaliswa), ukudilizwa, ukuguqulwa kwesigaba kanye nokuvuthwa kwe-Ostwald. 1. Ukugoba Amaconsi ahlakazekile ku-emulsion ahlangana ukuze akhe amaqoqo amaconsi anezinhlangothi ezintathu,...Funda kabanzi -

Ama-Ejenti Okuhlanza Indlu Ukuhlanza indlu kubhekisela ekuhlanzweni nasekugcinweni kwezakhiwo noma imishini yezimboni, njengokuhlanza phansi, izindonga, ifenisha, amakhaphethi, iminyango, amafasitela, nezindlu zangasese, kanye nokuhlanza indawo yamatshe, ukhuni, insimbi, nengilazi. Ama-ejenti okuhlanza anjalo ajwayelekile...Funda kabanzi -
Indlela yokusebenza kwezinyibilikisi ze-surfactant kanye nezici ezithinta ukuncibilika
Emkhakheni we-chemistry, amanye amakhemikhali e-organic, ngenxa yezakhiwo zawo zokungancibiliki noma ukuncibilika kancane emanzini, aletha izinkinga eziningi ekusetshenzisweni okusebenzayo. Kodwa-ke, lapho la makhemikhali e-organic ehlala ndawonye nama-surfactants, ukuncibilika kwawo kuyanda kakhulu, into eyenzeka...Funda kabanzi -
I-surfactant ye-cationic
Ama-surfactant e-cationic ngokuyinhloko ama-organic amine derivatives aqukethe i-nitrogen. Njengoba i-athomu ye-nitrogen kuma-molecule ayo iqukethe ama-electron amabili, ingahlangana ne-hydrogen kuma-molecule e-acid ngokusebenzisa izibopho ze-hydrogen, okubangela ukuthi iqembu lama-amino lithwale i-posi...Funda kabanzi -
Isenzo Sokuhlanza Ama-Surfactants — Izinhlobo Ezihlukahlukene Zama-Detergent
Isenzo sokuhlanza sama-surfactants siyisici esiyisisekelo esinikeza ama-surfactants usizo lwawo olukhulu kakhulu. Sihilelekile ekuphileni kwansuku zonke kwezinkulungwane zemindeni. Ngaphezu kwalokho, sisetshenziswa kakhulu ezimbonini ezahlukahlukene nakuzo zonke izinhlobo zokukhiqiza kwezimboni. I-detergent S...Funda kabanzi -
Umphumela wokungaguquguquki kwama-surfactants
Ukuhlanza ama-surfactants kuyisici esiyisisekelo esinikeza ama-surfactants ukusetshenziswa kwawo okuwusizo kakhulu. Kuhilelekile ekuphileni kwansuku zonke kwezinkulungwane zemindeni. Ngaphezu kwalokho, kusetshenziswa kakhulu ezimbonini ezahlukahlukene nakuzo zonke izinhlobo zokukhiqiza kwezimboni. Umphumela wokulwa nokuqina kwe-surfactan...Funda kabanzi -
Ukusetshenziswa kwama-surfactants aphansi kwe-foam ekuhlanzeni kwezimboni
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 i-low-fo...Funda kabanzi -
Izindlela zokususa amafutha nokuhlanza izindawo zensimbi!
Enqubweni yokukhiqiza imishini yensimbi, amafutha okugcoba ayizinto zokugcoba ezisetshenziselwa ukunciphisa ukumelana kokungqubuzana kwama-friction pair nokunciphisa ijubane lokuguguleka kwawo. Amafutha okugcoba nawo adlala indima efana nokupholisa, ukuhlanza, nokuvimbela ukungcola kwama-friction pair. Kodwa-ke, ukusetshenziswa kwamafutha okugcoba kungase...Funda kabanzi -
Kuneziningi kakhulu izithasiselo zezibulala-zinambuzane, uyazi ukuthi zingaki izinhlobo ezikhona?
Izithasiselo zezibulala-zinambuzane ziyizinto ezingeziwe ezingezwa ngesikhathi sokucubungula noma ukusetshenziswa kwezakhi zokubulala izinambuzane ukuthuthukisa izakhiwo zomzimba nezamakhemikhali zama-ejenti, ezaziwa nangokuthi izithasiselo zezibulala-zinambuzane. Izithasiselo ngokwazo azinawo umsebenzi webhayoloji, kodwa zingathinta ukulawula...Funda kabanzi -
Ukusetshenziswa kwama-Surfactants ekumbozeni
