Ama-surfactants ane-foam ephansi afaka phakathi ama-compounds amaningana angewona ama-ionic kanye nama-amphoteric anamakhono okusebenza abanzi kanye namathuba okusebenzisa. Kubalulekile ukuqaphela ukuthi la ma-surfactants awawona ama-ejenti angena-foam. Kunalokho, ngaphezu kwezinye izakhiwo, ahlinzeka ngendlela yokulawula inani le-foam ekhiqizwa kwezinye izinhlelo zokusebenza. Ama-surfactants ane-foam ephansi nawo ahlukile kuma-defoamers noma ama-antifoamers, okuyizithasiselo ezenzelwe ngqo ukunciphisa noma ukuqeda i-foam. Ama-surfactants anikeza eminye imisebenzi eminingi ebalulekile ekwakhiweni, okuhlanganisa ukuhlanza, ukumanzisa, ukuhlanganisa, ukusabalalisa, nokuningi.
Ama-surfactant e-Amphoteric
Ama-surfactant e-amphoteric anephrofayili ye-foam ephansi kakhulu asetshenziswa njengama-surfactant ancibilika emanzini ekwakhiweni okuningi kokuhlanza. Lezi zithako zinikeza izakhiwo zokuhlanganisa, ukuzinza, ukuhlanza, kanye nokumanzisa. Ama-surfactant amasha e-amphoteric asebenza kahle abonisa izici eziphansi kakhulu zokukhipha igwebu ngenkathi enikeza ukusebenza kokuhlanza, amaphrofayili amahle kakhulu ezemvelo nokuphepha, kanye nokuhambisana namanye ama-surfactant angewona ama-ionic, ama-cationic, kanye nama-anionic.
Ama-Alkoxylates angewona ama-ionic
Ama-alkoxylate ane-foam ephansi ane-ethylene oxide (EO) kanye nokuqukethwe kwe-propylene oxide (PO) angaletha ukusebenza okuphezulu kokuhlanza nokuhlanza ngesifutho kwezicelo eziningana zokuhlanza okuphezulu nokushukuma. Izibonelo zifaka phakathi izinsiza zokuhlanza izitsha ngokuzenzakalela, izihlanzi zobisi nokudla, izinhlelo zokucubungula i-pulp nephepha, amakhemikhali ezindwangu, nokuningi. Ngaphezu kwalokho, ama-alkoxylate asekelwe ku-alcohol abonisa izakhiwo eziphansi kakhulu zokukhipha igwebu futhi angahlanganiswa nezinye izingxenye ezine-foam ephansi (isb., ama-polymer ancibilika emanzini abolayo) ukuze kwakhiwe izihlanzi eziphephile nezingabizi.
Ama-EO/PO block copolymers aziwa ngezakhiwo zawo ezinhle kakhulu zokumanzisa nokuhlakaza. Izinhlobo ze-low-foam kulesi sigaba zingasebenza njenge-emulsifiers ephumelelayo yezicelo ezahlukene zokuhlanza zezimboni nezezikhungo.
Ama-Amine Oxides Ane-Foam Aphansi
Ama-amine oxide anezilinganiso ze-foam eziphansi kakhulu ayaziwa nangokusebenza kwawo kokuhlanza kuma-detergents nama-degreasers. Uma ehlanganiswa nama-hydrogel amphoteric ane-foam ephansi, ama-amine oxide angasebenza njengomgogodla we-surfactant emafomula amaningi okuhlanza izindawo eziqinile ezine-foam ephansi kanye nezicelo zokuhlanza insimbi.
Ama-Ethoxylates Otshwala Oqondile
Ama-ethoxylate athile otshwala aqondile abonisa amazinga e-foam aphakathi kuya kwaphansi futhi angasetshenziswa ezinhlotsheni ezahlukene zokuhlanza indawo eqinile. Lawa ma-surfactants anikeza izakhiwo ezinhle kakhulu zokuhlanza kanye nokumanzisa ngenkathi egcina amaphrofayili amahle ezemvelo, ezempilo, kanye nokuphepha. Ikakhulukazi, ama-ethoxylate otshwala aphansi e-HLB akhipha igwebu eliphansi kuya kweliphakathi futhi angahlanganiswa nama-methoxylate otshwala aphezulu e-HLB ukulawula igwebu nokuthuthukisa ukuncibilika kwamafutha ezinhlotsheni eziningi zokuhlanza zezimboni.
Ama-Ethoxylates Amafutha A-Amine
Amanye ama-ethoxylates e-fatty amine anezakhiwo eziphansi zokukhipha igwebu futhi angasetshenziswa ekusetshenzisweni kwezolimo kanye nasekuhlanzeni okujiyile noma ekwakhiweni okusekelwe ku-wax ukuze anikeze izakhiwo zokuhlanganisa, zokumanzisa, nezokusabalalisa.
