V. Organic Silicon Antifoamer
Polydimethylsiloxane, wanda kuma aka sani da man fetur na silicone, shine babban bangaren na defoamer na silicone. Idan aka kwatanta da ruwa da man fetur na kowa, tashin hankalinsa ya fi karami, wanda ya dace da tsarin kumfa na tushen ruwa da tsarin kumfa mai tushe. Silicone man yana da babban aiki, low solubility, barga sinadaran Properties, haske aikace-aikace kewayon, low volatility, mara guba, da kuma shahararren defoaming ikon. Rashin hasara shine rashin aikin hana kumfa mara kyau.
1. M Antifoamer
Solid Antifoamer yana da halaye na kwanciyar hankali mai kyau, tsari mai sauƙi, sufuri mai dacewa da sauƙin amfani. Ya dace da yanayin mai da lokacin ruwa, kuma nau'in watsawa na matsakaici shima sananne ne. Ana amfani da shi sosai a cikin filin ƙananan kumfa ko kumfa mara wanke foda.
2. Emulsion Antifoamer
The silicone man a emulsion defoamer yana da mafi girma tashin hankali, da emulsification coefficient ne ma girma. Da zarar an zaɓi emulsifier ɗin da bai dace ba, zai sa wakili mai lalata kumfa ya zama mai lanƙwasa da metamorphic cikin ɗan gajeren lokaci. Zaman lafiyar emulsion yana da matukar mahimmanci ga ingancin wakili mai lalata. Saboda haka, da shirye-shiryen na emulsion irin silicone defoamer mayar da hankali a kan zabi na emulsifier. A lokaci guda, emulsion defoamer yana da mafi girma sashi a cikin siliki defoamer tare da halaye na low price, m aikace-aikace ikon yinsa, bayyananne defoaming sakamako, da dai sauransu. Tare da ci gaban fasahar ƙira, emulsion defoamer zai haɓaka sosai.
3. Magani Antifoamer
Magani ne da aka yi ta hanyar narkar da man siliki a cikin sauran ƙarfi. Ka'idar lalata kumfa ita ce abubuwan da ke tattare da mai na silicone ana ɗaukar su ta hanyar kaushi kuma ana tarwatsa su a cikin maganin kumfa. A cikin wannan tsari, man siliki zai tattara a hankali a cikin ɗigon ruwa don kammala lalata. Man siliki da aka narkar da shi a cikin tsarin maganin kwayoyin da ba ruwa ba, kamar polychloroethane, toluene, da sauransu, ana iya amfani da shi azaman maganin defoaming mai.
4. Oil Antifoamer
Babban bangaren mai defoamer shine dimethyl silicone man. Pure dimethyl silicone man ba shi da wani defoaming sakamako da kuma bukatar a emulsified. A surface tashin hankali na emulsified silicone rage sauri, da kuma karamin adadin iya cimma karfi kumfa karya da hanawa. Lokacin da aka gauraya man siliki da wani kaso na mataimakan silica da aka yi musu maganin hydrophobically, ana iya samar da wani abu mai lalata mai. Silicon dioxide da ake amfani da matsayin filler, saboda babban adadin hydroxyl kungiyoyin a kan ta surface iya inganta watsawa ikon silicone mai a cikin kumfa tsarin, ƙara da kwanciyar hankali na emulsion, da kuma a fili inganta defoaming dukiya na silicone defoamer.
Saboda man fetur na siliki ne lipophilic, silicone defoamer yana da tasiri mai kyau na lalatawa akan maganin mai-mai narkewa. Koyaya, ya kamata a kula da waɗannan abubuwan yayin amfani da defoamer silicone:
● Ƙananan danko mai lalata silicone yana da sakamako mai kyau na lalata, amma dagewar sa ba shi da kyau; High danko silicone defoamer yana da jinkirin defoaming sakamako amma mai kyau dagewa.
● Idan danko na maganin kumfa ya yi ƙasa, yana da kyau a zaɓi na'urar defoamer na silicone tare da danko mafi girma. Sabanin haka, mafi girman danko na maganin kumfa shine, yana da kyau a zabi defoamer na silicone tare da ƙananan danko.
Weightarfin ƙwayoyin ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar silicone mai narkewa yana da wani tasiri akan tasirin sa.
● Mai cire foamer tare da ƙananan nauyin kwayoyin halitta yana da sauƙin tarwatsawa da narke, amma rashin dagewa. A akasin wannan, da defoaming yi na high kwayoyin nauyi defoamer ne matalauta, da emulsification da wuya, amma solubility ne matalauta da karko ne mai kyau.
