Ama-Foam Stabilizers

ama-foam stabilizers izinhlanganisela zamakhemikhali ezibambezela ukuhlangana kwamabhamuza egesi egwebu okuwenza azinze futhi afane.. Lawa ma-stabilizer asetshenziswa ekudleni naseziphuzweni.

Inqubo yokukhihliza amagwebu yenzeka lapho umoya uxutshwa noketshezi futhi igesi ibanjwa ama-molecule amaprotheni aqondaniswe phakathi kwamanzi nomoya.. Ukuphela kwe-hydrophobic kwamaprotheni kulenga emanzini kuyilapho isiphetho se-hydrophilic sikhomba emoyeni sakha ibhamuza elibukeka njengegwebu..

I-Nanoparticles njenge-Foam Stabilizer

Ama-nanoparticles aqashelwa kabanzi ngamakhono awo okusetshenziswa ekuqiniseni igwebu. Nokho, kunezinselelo eziningana ekusetshenzisweni kwe-nanoparticles ngale njongo. Lezi zinselelo zihlanganisa izindlela zokwenziwa, izakhiwo ze-nanoparticles nokukhathazeka kwemvelo (URafati et al., 2016).

Lawula amapharamitha we-Foam Stability

Imingcele yokulawula eyinhloko ekuzinzeni kwegwebu ihlanganisa ubukhulu be-nanoparticles, uhlobo lwe-nanoparticles, izinga lokushisa lamanzi, ukuhlushwa usawoti kanye modifiers. Usayizi omncane we-nanoparticles ungahlala ku-lamellae ngokuzinzile futhi uvimbele ukugeleza kwamanzi, kuyilapho ubukhulu obukhulu bungaba nzima ukugcina nokwandisa ububanzi be-nanoparticles (Pugh, 1996; U-Singh no-Mohanty, 2015).

Phakathi kwezinhlobo ezahlukene ze-nanoparticles, i-hydrophobic emaphakathi (i-angle yokuxhumana 90 deg) ama-nanoparticles ayengcono kakhulu ama-foam stabilizers. Bathuthukisa ukucindezela okukhulu kwe-capillary, yandisa amandla emishini ye-lamellae futhi yakha isakhiwo senethiwekhi ukuze kuncishiswe ukugeleza kwefilimu, ukunciphisa ukuhlangana kwamabhamuza futhi andise isikhathi sokuba khona kwesistimu yegwebu.
