2. emulsion saliid silikoon anionic hydroxyl

Caanaha hydroxyl-ka anionic waxaa lagu gartaa iswaafajinta wakiilka dharka, iyo emulsion waa mid aad u deggan.Gaar ahaan, inta badan kaaliyeyaasha daabacaadda dharka iyo rinjiyeynta waa anionic.Haddii emulsion cationic hydroxy loo isticmaalo, way fududahay in la keeno demulsification iyo saliid bleaching, halka anionic hydroxy emulsion ay ka fogaan karto khasaarahan, sidaas darteed aad ayey caan ugu tahay isticmaalayaasha oo si ballaaran loo isticmaalo.

3. Emulsion saliid silikoon ka kooban ionic hydroxyl

Inkasta oo cationic hydroxyapatite uu yahay jilciye dhar aad u fiican, emulsionkani maaha mid u adkaysta biyaha adag oo aan loo isticmaali karin dimethylolyl laba xabagta urea hydroxyurea.

Inkasta oo cationic hydroxyapatite uu yahay jilciye dhar aad u fiican, emulsionkani maaha mid u adkaysta biyaha adag, loomana isticmaali karo isla qubeyska dimethoxylated laba xabagta hydroxyvinyl urea (2D), kicinta magnesium chloride iyo wakiilka anionic.Intaa waxaa dheer, sababtoo ah xasilloonida liidata emulsion-ka, polymers silicone ayaa si fudud looga soocaa emulsion-ka waxayna ku sabeynayaan dusha dareeraha ah, oo badanaa loo yaqaan "saliid bleaching".Haddii emulsifiers cationic iyo non-ionic loo isticmaalo polymerization emulsion, cilladaha emulsifier cationic ee diyaarinta emulsion saliidda silikoon hydroxyl waa laga gudbi karaa.Emulsion silicone ee la diyaariyey wuxuu u adkeysan karaa biyaha adag, waxaana loo isticmaali karaa isla qubeys leh 2D resin, magnesium chloride iyo wakiilka caddeynta VBL, waxayna leedahay caabbinta kulaylka wanaagsan iyo caabbinta qaboojinta.

4. Emulsion saliid silikoon aan ionic hydroxyl ahayn

Caanaha Nonionic hydroxy waxay leeyihiin laqabsi iyo xasilooni ka wanaagsan caanaha hydroxy-ga ee go'doonsan, sidaa darteed wadamo badan ayaa dadaal weyn u galay inay daraasad ku sameeyaan caanaha nonionic hydroxy.Tusaale ahaan, UltrateX FSA, oo ah badeeco cusub oo lagu sameeyay Switzerland, waa emulsion aan-ionic ahayn oo leh miisaan kelli ah oo ka badan 200 kun iyo madaxa hydroxyl ee laba methylsiloxane.Waa tallaabo hore loo qaaday marka loo eego Dc-1111 anionic hydroxyapatite emulsion ee Maraykanka.

5. Wakiilka dhamaystirka Organosilicon oo leh kooxo kale oo firfircoon

Si loo daboolo baahiyaha dhamaystirka sare ee dhammaan noocyada kala duwan ee dharka, hagaajinta saliidda anti, anti-static iyo hydrophilic guryaha silikoon dhammayn, iyo ka dhigi dharka fiber kiimikaad leeyihiin faa'iidooyin badan oo dhar dabiiciga ah, shaqaalaha silicone bartay hordhaca ah Kooxaha kale ee firfircoon sida kooxda amino, kooxda amide, kooxda ester, kooxda cyano, kooxda carboxyl, kooxda epoxy, iwm. Horudhaca kooxahani waxay ka dhigaysaa wakiilka dhamaystirka dharka organosilicon saameyn gaar ah, tusaale ahaan, hordhaca ah ee kooxda amino galay organosilicon molecule. waxay ku habboon tahay preshrunk iyo dhamaystirka jilicsan ee dhogorta;soo bandhigida kooxda amide waxay ku haboon tahay dhamaystirka antifouling, iyo jilicsanaanta si weyn ayaa loo hagaajiyaa: soo bandhigida kooxda cyano waxay leedahay caabbinta saliidda wanaagsan, iyo saameynta anti-static ee copolymer ee ether polyoxyethylene iyo organosilicon waa mid wanaagsan;organosilicon-ka la beddelay ee organofluorine waxa uu leeyahay caabbinta saliidda.Ka-hortagga wasakhowga, ka-hortagga-static, ka-hortagga biyaha iyo faa'iidooyin kale oo badan.

Laba.Saliida Silicone emulsion defoamer

Silicone oil emulsion defoamer guud ahaan waa saliid ku jirta biyaha (O/W) emulsion, taas oo ah, biyuhu waa weji joogto ah, saliid silikoon waa weji joogsi ah.Waxaa hore loogu qasi jiray saliid silikoon, emulsifier iyo wakiilka dhumucdiisuna, ka dibna si tartiib tartiib ah ku dar biyo si ay u qaso, si joogto ah shiidi mashiinka kolloid ilaa emulsion la doonayo la helo.

Defoamer oil silikoon emulsion waa wakiilka defoaming si weyn loogu isticmaalo defoamer silicone.Waxaa si ballaaran loo isticmaali karaa sida foamer-ka habka aqueous.Marka la isticmaalo, emulsion-ka ayaa si toos ah loogu dari karaa nidaamka xumbo-saarka, iyo saameyn wanaagsan oo xunxun ayaa la heli karaa.Si loo wanaajiyo saamaynta defoaming ee emulsion iyo saxnaanta cabbirka, guud ahaan si toos ah looma isticmaalo in ka badan 10% emulsion saliid silikoon xoogga leh: marka hore, waxaa lagu qasi jiray 10% ama ka yar biyo qabow ama si toos ah xal xumbo.Taboo waa in lagu qaso dareere kulul ama aan la qaboojin, haddii kale waxay keeni doontaa demulsification emulsion.Xasiloonida emulsion-ku way ka sii dari doontaa qasidda ka dib, iyo ifafaale lakabka (saliid bleaching) ayaa laga yaabaa inay ku dhacdo habka kaydinta, taas oo ah, demulsification.Sidaa darteed, emulsion-ka la qasi jiray waa in loo isticmaalo sida ugu dhakhsaha badan.Haddii loo baahdo, dhumucyada ayaa lagu dari karaa si loo hagaajiyo xasilloonida emulsion.Hawlgalka dufcadda, emulsion saliidda silikoon ayaa lagu dari karaa ka hor inta aan nidaamku soconin ama dufcadaha.Hawlgalka joogtada ah, emulsion saliidda silikoon waa in lagu daraa si joogto ah ama si joogto ah qaybaha ku habboon ee nidaamka.

Isticmaalka emulsion defoamers, heerkulka iyo acid iyo xaaladaha alkaline ee nidaamka xumbo waa in la tixgeliyaa.Sababtoo ah emulsion saliidda silikoon waa mid aad u jilicsan, emulsion-keeda ayaa horay loo tirtiri doonaa, waxayna noqon doontaa mid aan waxtar lahayn ama aan waxtar lahayn.Qadarka emulsion saliidda silikoon guud ahaan waa 10 ilaa 10Oppm miisaanka dareeraha xumbo (sida ku cad mitirka saliidda silikoon).Dabcan, waxa kale oo jira in ka yar 10 ppm iyo in ka badan 100 ppm xaaladaha gaarka ah.Qiyaasta ku habboon inta badan waxaa lagu go'aamiyaa tijaabooyin.

Guud ahaan, defoamer saliidda silikoon waa badiyaa saliid ku jirta biyaha.Marka loo eego noocyada kala duwan ee saliidda silikoon, defoamer saliid silikoon ayaa leh noocyada soo socda:

1. Emulsion saliid silikoon oo ku salaysan laba saliid silikoon methyl

Foamer noocan oo kale ah wuxuu ka kooban yahay saliid dimethylsilicone, emulsifier iyo biyo.Waxaa si weyn loogu isticmaali karaa halsano, cuntada, waraaqaha, fiber, farmashiyaha, xabagta synthetic iyo wixii la mid ah.

2. emulsion saliid silikoon oo ku salaysan saliid silikoon methyl ethoxy

Noocan ah foamer-ka wuxuu ka samaysan yahay saliidda silikoon ee methyl ethoxy iyo wakiilkeeda isku dhafka ah.

3. Emulsion saliid silikoon ku salaysan saliid silikoon ethyl

Sanadihii la soo dhaafay, organosilicon defoamer ayaa u koraya dhanka xannibaadda isku-duubnida (ama isku-duubista) ee organosilicon polyeter.Foamer noocan oo kale ah wuxuu leeyahay sifooyinka organosilicon iyo polyeter labadaba, sidaas darteed xoogga foorida ayaa si weyn loo hagaajiyaa;organosilicon polyether copolymer defoamer, oo sidoo kale loo yaqaan is emulsifying organosilicon defoamer, waa silsilad ethylene oxide hydrophilic ama ethylene oxide propylene oxide silsilad block (ama meeris) ee silsiladda organosilicon molecular, si qaybta hydrophobic siloxane lagu daro hydrophilic polye.Sida foamer-ka, molecule-ka noocan oo kale ah wuxuu leeyahay isugeyn fiditaan ballaaran, wuxuu si siman u kala firdhi karaa xumbo-sameeyaha, wuxuuna leeyahay waxtarka foamer sare.Waa nooc cusub oo wax ku ool ah oo tayo sare leh.Saamaynta emulsifying ee saliid silikoon oo aan lahayn emulsifier waa mid ku qanacsan nidaamyada qaarkood.Waxay si gaar ah ugu habboon tahay kuwa aan ku habboonayn emulsion saliidda silikoonka guud iyo emulsion saliidda silikoon guud.
