Dab tsi yog txoj cai kho ntawm platinum catalyst?

Hauv kev kho cov tshuaj tiv thaiv ntawm cov ntaub ntawv silicone, platinum catalyst txhawb cov tshuaj tiv thaiv ntxiv ntawm hydrogenated silicone roj thiab vinyl silicone roj los ntawm kev muab cov chaw ua haujlwm, kom cov khoom siv silicone hloov ntawm cov kua rau cov khoom thiab paub txog cov txheej txheem kho. Cov txheej txheem tshuaj tiv thaiv tshwj xeeb yog raws li hauv qab no:
Lub silicon-hydrogen bond (Si-H) nyob rau hauv cov roj hydrogenated silicone yog qhib los ntawm platinum catalyst.
Cov activated silicon-hydrogen bond reacts nrog vinyl (C=C) nyob rau hauv cov roj hmab silicone los tsim ib tug tshiab silicon-carbon bond (Si-C).
Raws li cov tshuaj tiv thaiv tshwm sim, cov silicone molecules txuas ntxiv txuas mus rau kev tsim cov qauv peb sab, yog li ua tiav kev kho.
