• Faɗin aikace-aikace

Saboda tsarin sinadarai na musamman na man silicone, bai dace da ruwa ko abubuwan da ke ɗauke da ƙungiyoyin polar ba, ko kuma tare da hydrocarbons ko abubuwan halitta masu ɗauke da ƙungiyoyin hydrocarbon.Tun da man silicone ba shi da narkewa a cikin abubuwa da yawa, siliki na defoamer yana da aikace-aikace masu yawa.Ana iya amfani dashi ba kawai don lalata tsarin ruwa ba, har ma don lalata tsarin mai.

• Low surface tashin hankali

Tashin hankali na man silicone shine gabaɗaya 20-21 dynes / cm kuma ya fi ƙanƙanta da yanayin tashin hankali na ruwa (72 dynes / cm) da ruwa mai kumfa gabaɗaya, wanda ke haɓaka tasirin sarrafa kumfa.

• Kyakkyawan kwanciyar hankali na thermal

Ɗaukar man dimethyl silicone da aka saba amfani da shi a matsayin misali, juriyar zafinsa na dogon lokaci zai iya kaiwa 150 ° C, kuma juriyar zafinsa na ɗan gajeren lokaci zai iya kaiwa sama da 300 ° C, yana tabbatar da cewa ana iya amfani da abubuwan lalata silicone a cikin kewayon zafin jiki mai faɗi.

• Kyakkyawan kwanciyar hankali na sinadarai

Man siliki yana da kwanciyar hankali na sinadarai kuma yana da wahalar amsawa da sauran abubuwa.Sabili da haka, idan dai shirye-shiryen ya dace, ana ba da izinin yin amfani da ma'aikatan defoaming silicone a cikin tsarin da ke dauke da acid, alkalis, da salts.

• Inertia na jiki

An tabbatar da cewa man siliki ba shi da guba ga mutane da dabbobi.Saboda haka, silicone defoamers (tare da masu dacewa ba masu guba masu guba, da dai sauransu) za a iya amfani da su cikin aminci a cikin ɓangaren litattafan almara da takarda, sarrafa abinci, likita, magunguna da aikace-aikacen masana'antu na kwaskwarima.

• Ƙarfi mai ƙarfi

Silicone defoamers iya ba kawai yadda ya kamata karya data kasance maras so kumfa, amma kuma muhimmanci hana kumfa da kuma hana samuwar kumfa.Matsakaicin yana da ƙanƙanta sosai, kuma kawai miliyan ɗaya (1 ppm ko 1 g/m3) na nauyin matsakaicin kumfa za a iya ƙarawa don samar da tasirin lalata.Matsayinta gama gari shine 1 zuwa 100 ppm.Ba kawai tsadar kuɗi ba ne, amma ba zai ƙazantar da kayan da ake lalata kumfa ba.

Silicone antifoams suna da daraja don kwanciyar hankali, dacewa tare da abubuwa daban-daban, da tasiri a cikin ƙananan ƙira.Koyaya, yana da mahimmanci don tabbatar da cewa sun bi ƙa'idodin tsari kuma sun dace da takamaiman aikace-aikacen don guje wa kowane mummunan tasiri akan ingancin samfur ko muhalli.
