V. Organic Silicon Antifoamer
Polydimethylsiloxane, oo sidoo kale loo yaqaan saliid silikoon, waa qaybta ugu muhiimsan ee defoamer silikoon.Marka la barbardhigo biyaha iyo saliidda caadiga ah, xiisadeeda dusha sare waa ka yar tahay, taas oo ku habboon nidaamka xumbo-biyoodka ee biyaha iyo nidaamka xumbo-saldhigga saliidda.Saliidda Silikoon waxay leedahay firfircooni sare, milmayn hooseeya, guryaha kiimikaad deggan, kala duwanaanta codsiga iftiinka, isbeddel hoose, aan sun ahayn, iyo awoodda xumboynta caanka ah.Khasaaradu waa waxqabadka xannibaadda xumbo-xumada.
1. Antifoamer adag
Antifoamer adag waxay leedahay sifooyinka xasilloonida wanaagsan, habka fudud, gaadiidka ku habboon iyo isticmaalka sahlan.Waxay ku habboon tahay wajiga saliidda iyo biyaha labadaba, iyo nooca kala firdhinta dhexdhexaadka ah ayaa sidoo kale caan ah.Waxaa si ballaaran loo isticmaalaa berrinka xumbo yar ama budada dhaqidda xumbo-xumada.
2. Emulsion Antifoamer
Saliidda silikoon ee ku jirta emulsion defoamer waxay leedahay xiisad weyn, iyo isku-dhafka emulsification waa mid aad u weyn.Marka emulsifier-ga si aan munaasib ahayn loo doorto, waxay keeni doontaa in wakiilka xumbo-samaynta uu noqdo lakab iyo metamorphic waqti gaaban gudaheed.Xasiloonida emulsion-ka ayaa aad muhiim ugu ah tayada wakiilka xumbo-baxa.Sidaa darteed, diyaarinta nooca emulsion defoamer silicone waxay diiradda saartaa doorashada emulsifier.Isla mar ahaantaana, defoamer emulsion wuxuu leeyahay qiyaasta ugu weyn ee silikoon defoamer leh sifooyinka qiimaha jaban, baaxadda codsiga ballaaran, saameynta cad ee foaming, iyo wixii la mid ah.Horumarka tignoolajiyada qaabaynta, emulsion defoamer ayaa si weyn u horumarin doona.
3. Xalka Antifoamer
Waa xal la sameeyay iyadoo lagu milmay saliidda silikoonka ee dareeraha.Mabda'a xumbo-baxa ayaa ah in qaybaha saliidda silikoon ay qaadaan dareeraha oo lagu kala firdhiyo xal xumbo.Nidaamkan, saliidda silikoon ayaa si tartiib tartiib ah isugu ururin doonta dhibco si ay u dhamaystirto xumbo-samaynta.Saliida silikoon ee lagu milmay nidaamka xalalka organic non-aqueous, sida polychloroethane, toluene, iwm, waxa loo isticmaali karaa sidii xal saliid defoaming.
4. Saliida Antifoamer
Qaybta ugu muhiimsan ee defoamer saliidda waa saliid silikoon dimethyl.Saliida silikoon ee dimethyl oo saafi ah wax saameyn ah kuma leh oo waxay u baahan tahay in la damiyo.Xiisadda dusha sare ee silicone emulsified ayaa si degdeg ah hoos ugu dhacda, qadar yarna waxay gaari kartaa jabinta xumbo xoog leh iyo xannibaad.Marka saliidda silikoon lagu qaso qayb gaar ah oo ka mid ah caawiyayaasha silica hydrophobically daaweeyay, defoamer xarun saliid ayaa la samayn karaa.Silicon dioxide waxaa loo isticmaalaa sida buuxinta, sababtoo ah tiro badan oo ah kooxaha hydroxyl ee dusha sare waxay kor u qaadi kartaa awoodda kala firdhisan ee saliidda silikoon ee nidaamka xumbo, kordhinta xasiloonida emulsion ah, oo si cad u hagaajin hantida defoaming ee defoamer silicone ah.
Sababtoo ah saliidda silikoon waa lipophilic, silikoon defoamer wuxuu leeyahay saameyn aad u wanaagsan oo xumbo-xumo ah oo ku saabsan xalka saliidda-milaysa.Si kastaba ha ahaatee, qodobadan waa in fiiro gaar ah loo yeesho marka la isticmaalayo defoamer silicone:
● Viscosity hoose ee foamer silicone wuxuu leeyahay saameyn wanaagsan oo xumbo-jaris ah, laakiin adkaysigeedu waa liitaa;Viscosity-ga sare ee silikoon defoamer wuxuu leeyahay saamayn xumeynta oo gaabis ah laakiin adkaysi wanaagsan.
● Haddii viscosity of foaming foaming uu hooseeyo, waxa fiican inaad doorato foamer-ka silikoon oo leh aragti sare.Taas bedelkeeda, heerka sare ee viscosity ee xal xumbada waa, waxa fiican in la doorto defoamer silikoon leh viscosity hoose.
● Miisaanka molecular ee saliida defoamer ee saliidda leh ayaa saameyn gaar ah ku leh saameynteeda xumbo-jaridda.
● Xumbo-sameeyaha leh miisaan yar oo unugyadu waa ay fududahay in la firdhiyo lana milmi karo, laakiin adkaysi la'aan.Taas bedelkeeda, waxqabadka xumbo-baxa ee culeyska sare ee foamer waa mid liidata, emulsification-kuna waa adag yahay, laakiin milmayntu waa mid liidata oo adkeysigu waa wanaagsan yahay.
