Silicone emulsion (silicone emulsion luv luv) yog ib qho emulsion uas muaj cov roj hauv dej silicone roj, dej thiab surfactants.
Silicone emulsions feem ntau yog siv los ua cov khoom muag muag rau silicone roj fabrics. Thawj tiam ntawm silicone npuag tiav yog cov khoom sib xyaw ntawm dimethicone thiab hydrosilicone kua (thiab lawv cov derivatives). Qhov thib ob tiam silicone npuag xov tus neeg sawv cev yog hydroxy-terminated dimethicone emulsion, uas yog ua los ntawm octamethylcyclotetrasiloxane monomer, dej, emulsifier, catalyst thiab lwm yam raw khoom nyob rau hauv tej yam kev mob rau emulsion polymerization. Vim tias polymerization thiab emulsification tau ua tiav hauv ib kauj ruam, nws muaj qhov zoo ntawm cov sijhawm ua haujlwm luv, kev ua haujlwm siab, cov khoom siv yooj yim, kev ua haujlwm yooj yim, thiab lwm yam, thiab cov khoom tau txais emulsion ruaj khov heev, cov khoom sib txawv heev, thiab cov khoom siv polymer. nrog rau cov pab pawg nquag (hydroxyl pawg) ntawm ob qho kawg tuaj yeem ua rau muaj kev cuam tshuam ntxiv los tsim cov yeeb yaj kiab, uas yog qhov tsim nyog rau kev txhim kho daim ntawv thov cov nyhuv ntawm emulsion, uas yog dhau mus txog ntawm cov neeg kho tshuab. emulsified silicone roj.
Lub luag haujlwm ntawm silicone roj emulsions
Silicone roj emulsions yog cov khoom siv tshuaj lom neeg uas muaj ntau yam haujlwm thiab kev siv. Cov hauv qab no yog cov haujlwm tseem ceeb ntawm silicone roj emulsions:
1. Lubricant: Silicone roj emulsion tuaj yeem tsim cov zaj duab xis lubricating ntawm qhov chaw sib txhuam, txo kev sib txhuam thiab hnav, thiab txhim kho kev ua haujlwm thiab kev ua neej ntawm cov cuab yeej siv tshuab.
2. Anti-adhesive: Silicone roj emulsion tuaj yeem txo qhov adhesion ntawm cov khoom nto, tiv thaiv cov ntaub ntawv, cov khoom los yog cov nplaum los ntawm adhering rau cov khoom lossis cov cuab yeej, thiab pab txhawb kev ua haujlwm tom qab.
3. Preservatives: Silicone roj emulsion tuaj yeem tsim cov yeeb yaj kiab tiv thaiv kom tsis txhob oxidation thiab corrosion ntawm cov hlau nto thiab ua kom lub neej ntev ntawm cov khoom siv thiab cov khoom siv.
4. Insulating tus neeg saib xyuas: Silicone roj emulsion muaj cov khoom siv hluav taws xob zoo thiab tuaj yeem siv rau hauv cov khoom siv hluav taws xob, cov xov hlau thiab cov cables, cov ntaub ntawv insulating thiab lwm yam kev lag luam los tiv thaiv tam sim no to thiab tsis ua hauj lwm.
5. Cov khoom siv tu tawv nqaij: Silicone roj emulsion yog dav siv hauv cov khoom siv tu tawv nqaij, nws tuaj yeem tsim cov yeeb yaj kiab tiv thaiv kom cov tawv nqaij noo thiab du, thiab tiv thaiv dej evaporation thiab lwm yam khaus.
6. Tus neeg saib xyuas kev kho deg: Silicone roj emulsion tuaj yeem siv rau kev kho saum npoo, muab qhov zoo nkauj thiab ci ntsa iab, ua kom lub ntsej muag ci thiab pom kev ntawm cov khoom.
Lub hauv paus ntsiab lus ntawm disilicone roj emulsion
Lub hauv paus ntsiab lus ntawm silicone roj emulsion yog raws li emulsification technology, uas ua ke cov roj silicone nrog ib tug haum emulsifier kom nws muaj peev xwm miscible nrog dej thiab tsim ib tug emulsion. Cov hauv qab no yog cov hauv paus ntsiab lus ntawm silicone roj emulsion:
1. Kev xaiv emulsifier: Xaiv txoj cai emulsifier yog ib kauj ruam tseem ceeb. Cov emulsifiers muaj xws li surfactants, surfactants, lossis colloidal tshuaj, uas muaj hydrophilic thiab hydrophobic moieties uas txo qhov nro ntawm cov kua thiab pab txhawb cov txheej txheem emulsification.
2. Kev npaj ntawm emulsion: Silicone roj thiab emulsifier yog tov nyob rau hauv ib qho kev faib ua feem thiab emulsified los ntawm txhua yam stirring los yog ultrasonic kev kho mob, thiaj li hais tias cov silicone roj yog finely dispersed nyob rau hauv lub aqueous theem los tsim ib tug emulsion.
3. Stabilize lub emulsion: Lub luag haujlwm ntawm emulsifier yog los txo qhov nro ntawm cov kua thiab tsis txhob sib sau ua ke thiab sib cais ntawm cov tee dej. Thaum lub sij hawm emulsification txheej txheem, lub concentration ntawm emulsifier thiab lub sij hawm emulsification yuav tsum tau tswj kom tau ib tug ruaj khov emulsion kua.
4. Daim ntawv thov emulsion: ruaj khov silicone roj emulsion tuaj yeem siv ncaj qha rau thaj chaw uas yuav tsum tau lubrication, tiv thaiv adhesion, tiv thaiv corrosion, thiab lwm yam. Nyob ntawm cov kev xav tau tshwj xeeb, cov qauv sib txawv ntawm emulsion thiab ntau ntau tuaj yeem xaiv.
