Antifoamers waxaa loo isticmaalaa si loo yareeyo xiisadda dusha sare ee biyaha, xalka iyo joojinta, ka hortagga sameynta xumbo, ama la yareeyo xumbo la sameeyay inta lagu jiro wax soo saarka warshadaha.Antifoamers-ka caadiga ah waa sida soo socota:
I. Saliida Dabiiciga ah (ie Saliida Soybean, Saliida Galleyda, iwm.)
Faa'iidooyinka: la heli karo, kharash-ool ah oo sahlan isticmaalka.
Khasaaro: way fududahay in la xumaado oo la kordhiyo qiimaha aysiidhka haddii aan si fiican loo kaydin.
II.Khamri Kaarboon Sare leh
Khamriga kaarboonka sarreeya waa molecule toosan oo leh hydrophobicity xooggan iyo hydrophilicity daciif ah, taas oo ah antifoamer wax ku ool ah nidaamka biyaha.Saamaynta antifoaming ee khamriga waxay la xiriirtaa milanka iyo faafinta xalka xumbo.Khamriga C7 ~ C9 waa Antifoamers-ka ugu waxtarka badan.Khamriga kaarboonka sare ee C12 ~ C22 waxaa lagu diyaariyaa emulsifiers ku habboon oo leh cabbirka qayb ka mid ah 4 ~ 9μm, oo leh 20 ~ 50% emulsion biyaha, taas oo ah, defoamer nidaamka biyaha.Ester-yada qaar ayaa sidoo kale saameyn antifoaming ku leh halsano penicillin, sida phenylethanol oleate iyo lauryl phenylacetate.
III.Polyether Antifoamers
1. GP Antifoamers
Waxaa lagu sameeyay polymerization of propylene oxide, ama isku dar ah ethylene oxide iyo propylene oxide, oo leh glycerol oo ah wakiilka bilawga ah.Waxay leedahay hydrophilicity liidata iyo milanka hooseeya ee dhexdhexaadinta xumbo, sidaas darteed waxay ku habboon tahay in loo isticmaalo dareeraha halsano khafiif ah.Maaddaama ay awooddeeda antifoaming ay ka sarreyso tii foaming, waxay ku habboon tahay in lagu daro dhexdhexaadinta basal si loo xakameeyo habka xumbo-saarka ee habka halsano oo dhan.
2. GPE Antifoamers
Ethylene oxide waxaa lagu daraa dhamaadka silsiladda polypropylene glycol ee isku xirka GP Antifoamers si loo sameeyo polyoxyethylene oxypropylene glycerol leh dhamaadka hydrophilic.GPE Antifoamer waxay leedahay hydrophilicity wanaagsan, awood antifoaming xoog leh, laakiin sidoo kale waxay leedahay milmayn weyn taas oo keenta waqti gaaban dayactirka hawlaha antifoaming.Sidaa darteed, waxay saameyn wanaagsan ku leedahay maraq halsano viscous.
3. GPEs Antifoamers
Copolymer-ka xannibaadda leh ee silsiladaha hydrophobic ee labada cidhifood iyo silsiladaha hydrophilic ayaa la sameeyay iyadoo lagu xidho dhamaadka silsiladda GPE Antifoamers oo leh stearate hydrophobic.Unugyada qaab-dhismeedkan leh waxay u muuqdaan inay ku ururaan is-dhex-galka dareeraha-gaaska, markaa waxay leeyihiin dhaqdhaqaaq xoog leh oo dusha sare ah iyo waxtarka xumbo-baxa weyn.
IV.Silikoon la beddelay oo Polyeter-ka ah
Polyether Modified Silicone Antifoamers waa nooc cusub oo tayo-saar sare leh.Waa wax-ku-ool ah faa'iidooyinka kala firdhisanaanta wanaagsan, awoodda xakamaynta xumbo xoog leh, xasillooni, aan sun ahayn oo aan waxyeello lahayn, isbeddel hoose iyo awoodda Antifoamers xooggan.Marka loo eego hababka isku xirka gudaha ee kala duwan, waxa loo qaybin karaa labada qaybood ee soo socda:
1. Copolymer leh -Si-OC- bond oo lagu diyaariyey aashito ahaan.Foamer-kani waa sahlan tahay in la nadiifiyo oo uu leeyahay xasillooni darro.Haddii kaydka amine uu jiro, waa la hayn karaa wakhti dheer.Laakiin sababtoo ah qiimihiisu hooseeya, awoodda korriintu waa mid aad u muuqata.
2. Copolymer bonded by - si-c-bond waxa uu leeyahay qaab-dhismeed xasiloon waxaana lagu kaydin karaa in ka badan laba sano xaalado xiran.Si kastaba ha noqotee, iyadoo ay ugu wacan tahay isticmaalka platinum qaali ah oo kicinaya geeddi-socodka wax-soo-saarka, kharashka wax-soo-saarka ee noocan ah ee antifoamers waa mid sarreeya, sidaas darteed si ballaaran looma isticmaalin.
