Ii-antifoamers zisetyenziselwa ukunciphisa uxinzelelo lwamanzi, isisombululo kunye nokunqunyanyiswa, ukuthintela ukwenziwa kwe-fim, okanye ukunciphisa i-foam eyenziwe ngexesha lokuveliswa kwemizi. Ii-antifoaaders eziqhelekileyo zezi zilandelayo:
I-IGI yeNdalo (okt ioyile yesoybebe, ioyile ye-CORN, njl. Njl.)
Izibonelelo: Ifumaneka, isetyenziswe ngendleko kunye nelula.
Izinto ezingalunganga: Kulula ukonakalisa kwaye unyuse ixabiso le-acid ukuba aligcinwa kakuhle.
II. Ikharbon yotywala ephezulu
Ikharbhoni ephezulu yotywala yimolekyuli ye-hydrophobicity eqinileyo kunye ne-hydrophiility ye-hydrophiility, eyi-antifoamer esebenzayo kwiNkqubo yamanzi. Iziphumo zokuchasana notywala zihambelana nokuluka kwayo kwaye zahlukile kwisisombululo esingcolileyo. Utywala be-C7 ~ c9 zezona zinto zisebenzayo. I-carbon yotywala ephezulu ye-C12 ~ C22 ilungiselelwe nge-EMulSISIREDs efanelekileyo ene-4 ~ Abanye abantu banayo nefuthe elibi kwi-penicillin ukuvela, njenge-phenylethanol oleate kunye neLauryl phenylacetate.
III. I-Polyeeter Antifoaders
1. I-Antifoaders
Yenziwe ngokungangenzi i-polymering ye-propylene oxide, okanye umxube we-Ethylene oxide kwaye i-propylene oxide, nge-glycerol njengearhente yokuqala. Ine-hydrophility ye-hydrophicicicility kunye nomhlaba ophantsi we-straing ophakathi, ngoko kufanelekile ukuba isetyenziswe kulwelo oluncinci lokubila. Kuba ubuchule bayo obucaphukileyo bungaphezulu kolo wokuphosa, kufanelekile ukuba bongezelwe kwi-bassium ephakathi ukuthintela inkqubo yokufihlakeleyo.
I-2. I-GPE Antiifoaders
I-Ebanonene Oxide yongezwa ekupheleni kwe-Polypropylene Glycopy Chain ye-GP AntifoPhylene Glycerol ye-phlycerol. I-GPE I-Antifoamer inee-hydrophiility ezilungileyo, ubuchule obuqinileyo, kodwa zinomhlaba omkhulu obangela ixesha elifutshane lokulungisa umsebenzi. Ke ngoko, inefuthe elihle kumhluzi wobubi lwe-viscous.
I-3. I-GNS Antifoaders
Ibhloko ye-copolymer enemixokelelwane ye-hydrophobic kuzo zombini iziphelo kunye neentambo ze-hydrophilic zisenziwa ngokutyhila i-chain ye-chain antifophorate. Iimolekyuli ezinolu lwakhiwo zidla ngokuhlanganisana kwi-interface yegesi-yolwelo, ngoko ke banomsebenzi onamandla omphezulu kunye nokusebenza kakuhle kokuphosa.
Iv. I-Polyetter iguqulwe i-Silicone
I-Polyetter eguqulweyo ye-wilicone antiifones luhlobo olutsha lweeDemomerisdieds eziphezulu. Isebenza ngexabiso lezinto eziluncedo kokusasazeka kokusasazeka, amandla omthibi omeleleyo, uzinzo, ukungabi nabungozi kwaye kungabi nabungozi, okuphantsi, kunye nobuchule obuqinileyo be-antifoamers. Ngokwendlela eyahlukeneyo yoqeqesho lwangaphakathi, iyahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulwahlulo lulandelayo:
I-1. Lo Defoamer kulula kwi-hydrolysis kwaye uziva uzinzo olungalunganga. Ukuba i-Amine Buffer ikhona, inokugcinwa ixesha elide. Kodwa ngenxa yexabiso layo eliphantsi, amandla okuphuhlisa ngokucacileyo.
2. I-Copolymer ibotshwe ngu--I-C-Bond inesimo esizinzileyo kwaye sinokugcinwa iminyaka emibini phantsi kweemeko ezivaliweyo. Nangona kunjalo, ngenxa yokusetyenziswa kwePlatinam ebiza ixabiso eliphambili njengeyona nkqubo yemveliso, iindleko zemveliso yolu hlobo lwee-antifoadars ziphezulu, ngenxa yoko ayisetyenziswanga.
V. I-Organic Silicon Antifoamer
... Isahluko esilandelayo.
Ixesha lokuposa: I-Nov-19 ukuya kwi-1921
