3. Waterproof and Anti-Stick Coating Baking Mold Anti-Stick Coating Process: Hydrogen-containing silicone oil + vinyl resin, contact angle >110℃tom qab kho. Textile Waterproof Finishing Effects: Reacts nrog fiber ntau hydroxyl pawg kom ua tiav ntev -kev ua dej tsis zoo (zoo tom qab 50 ntxuav). 4. Toughening Mechanism of Engineering Plastics (xws li PC, ABS) nyob rau hauv cov yas thiab Roj Hmab Hloov Kho: Sab - saw Si-H reacts nrog cov yas tsis kam. Piv txwv ntawm kev kho hydrophobic rau cov khoom siv roj hmab: Txheej txheej ntawm lub tsheb roj hmab qhov chaw kom txo tau cov coefficient ntawm kev sib txhuam.
5. Defoamer (Industrial Grade): Defoaming formulation for oil extraction: Hydrogen-muaj silicone oil + hydrophobic SiO₂, resistant to high temperature and pressure.
III. Kev xaiv Hydrogen-Cov roj Silicone
Platinum Catalyst Matching Dosage: 1 ~ 50 ppm (Ntau dhau yuav ua rau muaj kev phiv los yog toxicity). Inhibitor: Ntxiv ethynyl alcohols (piv txwv li, 1-ethynyl-1-cyclohexanol) kom ncua kev kho thiab hloov mus rau lub sijhawm ua haujlwm.
Txheej Txheem Tswj Kev Kub Kub: 80℃~ 150℃(siab kub ceev cov tshuaj tiv thaiv, kub qis txo npuas). Nqus Degassing: Zam kev tso tawm cov pa roj hydrogen los ntawm Si-H cov tshuaj tiv thaiv, uas tuaj yeem ua rau npuas.
IV. Kev ceev faj rau kev siv
Cia Lub Sijhawm: Yuav tsum tau kaw thiab tiv thaiv lub teeb kom tiv thaiv hydrolysis ntawm Si-H bonds (tsim hydrogen gas). Catalyst Matching: Platinum catalyst ntau npaum li cas 1 ~ 50 ppm kom tsis txhob muaj leej faj thiab amine lom. Kev Tswjhwm: Kho qhov kub thiab txias: 80℃~ 150℃(siab kub ceev cov tshuaj tiv thaiv). Nqus Degassing: Zam Si-H sab kev tshwm sim uas tsim npuas. VI. Cov Lus Qhia Yav Tom Ntej Technology: Tsawg Volatility: Txo kev kho cov shrinkage thiab txhim kho kev ntseeg siab ntawm cov khoom siv hluav taws xob. Photocuring Hloov Kho: Tsim UV- ua rau crosslinking hydrogen- muaj cov roj silicone rau txheej txheej. Nanocomposites: Ib txhij txhim kho thermal conductivity thiab mechanical zog los ntawm SiO₂ / graphene hloov kho.
Cov ntsiab lus: Sab -chain hydrogen- muaj cov roj silicone, nrog rau lawv ntau qhov chaw ua haujlwm thiab kev sib txuas siab siab, tau dhau los ua cov ntaub ntawv tseem ceeb rau cov nplaum hluav taws xob, kev kho mob silicone, thiab siab -kawg coatings. Tus yuam sij rau lawv daim ntawv thov nyob rau hauv: precisely tswj cov ntsiab lus hydrogen (0.1% ~ 1.5%) kom phim cov kev ua tau zoo; optimizing lub catalyst system (platinum / inhibitor) kom sib npaug curing ceev thiab operability; thiab sib txuas cov tshuab muab tub lim (xws li thermally conductive / conductive fillers) kom nthuav dav cov ntawv thov.
