Defoamer na ƙarni na uku wani sinadari ne na silicone wanda aka gina shi da polydimethylsiloxane (PDMS, man dimethyl silicone). A halin yanzu, bincike da amfani da wannan ƙarni na defoamers sun taru a China. PDMS ya ƙunshi sarkar iskar oxygen ta silicon da sauran ƙungiyoyin halitta, kuma ba za a iya shirya shi sosai a kan fim ɗin ruwa na kumfa ba, don haka kumfa zai fashe. Ƙananan danko PDMS yana da kyakkyawan sinadari na defoaming kuma babban danko PDMS yana da kyakkyawan sinadari na defoaming.

Rashin amfani da silicone defoamer
1. Yana da wuya a warwatse a cikin tsarin ruwa.
2. Saboda yana narkewa a cikin mai, tasirin lalata tsarin mai yana raguwa.
3. Rashin juriya ga yanayin zafi mai tsanani.
4. Rashin juriya ga ƙarfin alkaline.
Babban farashi:PDMS wani ruwa ne mai narkewar mai (O/W) wanda aka yi da man shafawa na silicone, emulsifier, mai kauri, da sauransu, wanda ruwa ke narkewa. Tashin hankalin saman yana raguwa da sauri kuma yana da tasirin hana kumfa da hana kumfa.
