Silikonidefoamerfarin danko ne emulsion. An yi amfani da shi a fannonin masana'antu daban-daban tun daga shekarun 1960, amma babban ci gaba da haɓaka cikin sauri ya fara a cikin 1980s. A matsayin organosilicondefoamer, filayen aikace-aikacensa kuma suna da faɗi sosai, suna daɗa jan hankali daga kowane fanni na rayuwa. A cikin sinadarai, takarda, sutura, abinci, yadi, magunguna da sauran sassan masana'antu, siliconedefoamerƙari ne mara makawa a cikin tsarin samarwa. Ba zai iya kawai cire kumfa a kan ruwa surface na tsari matsakaici a cikin samar tsari, game da shi inganta tacewa, The rabuwa, gasification, da ruwa magudanun ruwa effects na wanka, hakar, distillation, evaporation, dehydration, bushewa da sauran fasaha matakai tabbatar da iya aiki na daban-daban kayan ajiya da sarrafa kwantena.

1. Faɗin aikace-aikace: saboda tsarin sinadarai na musamman na man silicone, bai dace da ruwa ko abubuwan da ke ɗauke da ƙungiyoyin polar ba, kuma ba tare da hydrocarbons ko abubuwan halitta waɗanda ke ɗauke da ƙungiyoyin hydrocarbon ba. Saboda rashin daidaituwa na man siliki zuwa abubuwa daban-daban, yana da aikace-aikace masu yawa. Ana iya amfani dashi don lalata kumfa a cikin tsarin ruwa da kuma a cikin tsarin mai.
2. Low surface tashin hankali: The surface iya aiki na silicone man ne kullum 20-21 dyne / cm, wanda shi ne karami fiye da na ruwa (72 dyne / cm) da kuma general kumfa taya, kuma yana da kyau defoaming yi.
3. Kyakkyawan kwanciyar hankali na thermal: Ɗaukar simethicone da aka saba amfani da shi a matsayin misali, yana iya jure 150°C na dogon lokaci da 300°C na ɗan lokaci kaɗan, kuma haɗin Si-O ɗinsa ba zai ruɓe ba. Wannan yana tabbatar da cewasilicone defoamerana iya amfani dashi a cikin kewayon zafin jiki mai faɗi.
4. Kyakkyawan kwanciyar hankali: Tun da haɗin Si-O yana da ɗan kwanciyar hankali, kwanciyar hankali na sinadarai na man siliki yana da yawa sosai, kuma yana da wuya a yi hulɗa da wasu abubuwa. Don haka, idan dai tsarin ya dace.silicone defoamersAn yarda a yi amfani da su a cikin tsarin da ke dauke da acid, alkalis, da salts.
5. Rashin kuzarin jiki: Man siliki an tabbatar da cewa ba mai guba bane ga mutane da dabbobi, kuma rabin adadinsa na mutuwa ya fi 34 g/kg. Don haka,silicone defoamers(tare da emulsifiers masu dacewa marasa guba, da sauransu) ana iya amfani da su cikin aminci a cikin masana'antar abinci, likitanci, magunguna da masana'antar kwaskwarima.
6. Ƙarfin zubar da kumfa:Silicone defoamerba zai iya karya kumfa da aka samar kawai yadda ya kamata ba, amma kuma yana iya hana kumfa mai mahimmanci kuma ya hana samuwar kumfa. Amfaninsa kadan ne, idan dai an ƙara kashi ɗaya a kowace miliyan (1ppm) na nauyin matsakaicin kumfa, zai iya haifar da lalata kumfa. Yawan amfani da shi shine 1 zuwa 100 ppm. Ba wai kawai tsadar kuɗi ba ne, amma kuma baya ƙazantar da abubuwan da aka lalatar.

Lalacewarsilicone defoamers:
a. Polysiloxane yana da wuyar tarwatsawa: Polysiloxane yana da wuyar narkewa a cikin ruwa, wanda ke hana yaduwarsa a cikin tsarin ruwa. Dole ne a ƙara wakili mai watsawa. Idan an ƙara wakili mai rarrabawa, emulsion zai zama barga kuma tasirin lalata zai canza. Talakawa, wajibi ne a yi amfani da ƙananan emulsifier don yin tasirin lalata mai kyau da kwanciyar hankali na emulsion.
b. Silicone ne mai-mai narkewa, wanda rage ta defoaming sakamako a cikin mai tsarin.
