Silane coupler KH-791 CAS: 5089-72-5

Silane coupler KH-791, yog ib qho bifunctional organosilane compound, yog tsim los daws qhov teeb meem ntawm kev ua tiav kev sib txuas thiab kev sib haum xeeb ntawm cov khoom sib txawv, tshwj xeeb tshaj yog cov inorganic substrates thiab cov organic polymers. Nrog nws ob qho kev ua haujlwm los ntawm triethoxysilane thiab epoxy pawg, KH-791 ua haujlwm ua tus choj, txhawb kev sib txuas zoo thiab txhim kho kev ua tau zoo ntawm cov khoom sib xyaw thiab cov khoom sib dhos. Hauv cov khoom sib xyaw, KH-791 ua haujlwm ua tus txhawb nqa kev sib txuas los ntawm kev tsim kom muaj kev sib txuas zoo ntawm cov khoom siv reinforcing, xws li iav lossis cov khoom me me, thiab cov polymer matrix. Cov khoom silane ntawm KH-791 dhau los ntawm hydrolysis thaum kov cov dej noo, tsim cov pab pawg reactive silanol uas yooj yim sib txuas rau ntawm qhov chaw ntawm cov inorganic substrate. Tib lub sijhawm, epoxy functionality cuam tshuam nrog cov polymer matrix, pab txhawb kev sib txuas covalent thiab txhim kho kev sib raug zoo thiab kev sib cais ntawm cov khoom sib xyaw hauv cov polymer, thaum kawg ua rau muaj kev txhim kho cov khoom siv kho tshuab thiab kev ua haujlwm ntev ntawm cov khoom sib xyaw. Ntxiv mus, KH-791 lub peev xwm hloov kho qhov chaw nthuav dav mus rau nws siv rau hauv cov nplaum thiab cov sealant formulations, qhov twg nws txhim kho cov yam ntxwv ntawm cov substrates, suav nrog cov hlau thiab cov hlau oxides. Los ntawm kev txhawb nqa kev sib txuas ntawm qib molecular, nws txo cov teeb meem cuam tshuam nrog kev tawg thiab kev ua tsis tiav ua ntej, ua kom ntseeg tau tias muaj kev ntseeg siab thiab kev ua tiav ntawm cov khoom sib dhos hauv kev tsim kho, tsheb, thiab kev siv aerospace. Hauv cov txheej txheem thiab cov ntawv thov kho qhov chaw, KH-791 ua haujlwm ua tus neeg sawv cev sib txuas, ua rau muaj kev sib txuas ntawm cov txheej txheem tiv thaiv lossis kho kom zoo nkauj rau ntau yam substrates, xws li iav, ceramics, thiab hlau. Nws lub peev xwm los sib txuas nrog qhov chaw substrate los ntawm silanol condensation reactions ua rau muaj kev tiv thaiv zoo dua rau dej, tshuaj lom neeg, thiab kev puas tsuaj ib puag ncig, yog li ua kom lub neej kev pabcuam thiab kev ua tau zoo ntawm cov nto coated. Hauv kev xaus, silane coupler KH-791 sawv cev ua ib qho tseem ceeb hauv thaj chaw ntawm kev txhawb nqa kev sib txuas thiab kev hloov kho qhov chaw, muab cov kev daws teeb meem rau kev txhim kho kev sib raug zoo, kev sib txuas, thiab kev ua tau zoo ntawm cov khoom sib xyaw, nplaum, thiab txheej txheem. Nws qhov xwm txheej ntau yam thiab kev sib raug zoo nrog ntau yam khoom siv ua rau nws yog ib qho cuab yeej tseem ceeb rau cov neeg tsim khoom thiab cov chaw tsim khoom nrhiav kev ua kom zoo dua cov khoom thiab lub neej ntev ntawm lawv cov khoom thoob plaws ntau yam lag luam.
