Imaphi ama-surfactants angasetshenziswa ukulawula igwebu ngesikhathi sokuhlanza?

Ama-surfactants anegwebu eliphansi ahlanganisa izinhlanganisela ezimbalwa ze-nonionic ne-amphoteric ezinamandla okusebenza okubanzi kanye nokwenzeka kokusebenza. Kubalulekile ukuqaphela ukuthi lawa ma-surfactants awawona ama-zero-foaming agents. Kunalokho, ngaphezu kwezinye izakhiwo, zinikeza indlela yokulawula inani legwebu elikhiqizwa kwezinye izinhlelo zokusebenza. Ama-surfactants anegwebu eliphansi nawo ahlukile kuma-defoam noma ama-antifoam, okuyizithasiselo eziklanyelwe ukunciphisa noma ukuqeda igwebu. Ama-surfactants anikeza eminye imisebenzi eminingi ebalulekile ekuhlanganiseni, okuhlanganisa ukuhlanza, ukumanzisa, ukufaka i-emulsifying, ukuhlakaza, nokuningi.

Ama-Amphoteric Surfactants.

Ama-amphoteric surfactants anamaphrofayili egwebu aphansi kakhulu asetshenziswa njengama-surfactants ancibilika emanzini ekwenziweni okuningi kokuhlanza. Lezi zithako zinikeza ukuhlanganisa, ukuzinza, ukuhlanza nokumanzisa izakhiwo. Ama-amphoteric surfactants anoveli anoveli abonisa izici eziphansi kakhulu zokukhihliza amagwebu kuyilapho ehlinzeka ngokusebenza kokuhlanza, amaphrofayili emvelo amahle kakhulu nokuphepha, nokuhambisana namanye ama-nonionic, cationic, kanye nama-anionic surfactants.

I-Nonionic Alkoxylates.

Ama-alkoxylates anegwebu eliphansi ane-ethylene oxide (EO) kanye nokuqukethwe kwe-propylene oxide (PO) angaletha ukusebenza okuphakeme kokuwasha nokufutha kwezinhlelo zokusebenza ezimbalwa zokuhlanza eziphakeme kanye nezokuhlanza. Izibonelo zifaka izinsiza zokugeza izitsha ezizenzakalelayo, izihlanzi zobisi nokudla, izinhlelo zokusebenza zokucubungula i-pulp nephepha, amakhemikhali ezindwangu, nokunye. Ukwengeza, ama-alkoxylates asekelwe kutshwala anomugqa abonisa izici zokugwedla eziphansi kakhulu futhi angahlanganiswa nezinye izingxenye ezinegwebu eliphansi (isb, ama-polymers ancibilikayo emanzini angaboli) ukuze enze izihlanzi eziphephile nezongayo.

I-EO/PO Block Copolymers.

Ama-copolymers e-EO/PO block aziwa ngezici zawo ezinhle kakhulu zokumanzisa nokuhlakaza. Izinhlobonhlobo ezinegwebu eliphansi kulesi sigaba zingasebenza njengezifanisi ezisebenza kahle zezinhlelo zokusebenza ezihlukene zokuhlanza izimboni nezikhungo.

.I-Low-Foam Amine oxides

Ama-amine oxide anezilinganiso zegwebu eliphansi kakhulu abuye aqashelwe ngokusebenza kwawo kokuhlanza ezintweni zokuhlanza neziwashisi amafutha. Uma ehlanganiswe nama-amphoteric hydrogel anegwebu eliphansi, ama-amine oxide angasebenza njengomgogodla osuselwe ekwakhekeni okuningi kwezihlanzi eziqinile ezinegwebu eliphansi kanye nezinhlelo zokuhlanza insimbi.

I-Linear Alcohol Ethoxylates.

Amanye ama-alcohol ethoxylates athile abonisa amazinga egwebu aphakathi nendawo ukuya kwaphansi futhi angasetshenziswa ezinhlelweni ezihlukahlukene zokuhlanza indawo eqinile. Lawa ma-surfactants ahlinzeka ngezindawo ezinhle kakhulu zokuhlanza nokumanzisa kuyilapho egcina amaphrofayili emvelo enempilo, ezempilo kanye nokuphepha. Ikakhulukazi, i-low-HLB alcohol ethoxylates iphansi ukuya ekukhipheni amagwebu ngokusesilinganisweni futhi ingahlanganiswa ne-high-HLB alcohol methoxylates ukulawula igwebu nokuthuthukisa ukuncibilika kwamafutha ekwakhekeni okuningi kokuhlanza izimboni.

I-Fatty Amine Ethoxylates.

Amanye ama-amine ethoxylates anamafutha anezindawo ezikhihliza amagwebu aphansi futhi angasetshenziswa ezinhlelweni zezolimo nasekuhlanzeni okujiyile noma ukwakheka okususelwe ku-wax ukuze kuhlinzekwe izakhiwo zokuhlanganisa, zokumanzisa, nezihlakazayo.
