Nkag siab txog Hydrosilylation Reactions
Hydrosilylation yog ib qho kev sib ntxiv ntawm silicon -hydrogen (Si-H) pawg thiab carbon-carbon ob daim ntawv cog lus, feem ntau catalyzed los ntawm platinum complexes.
Cov tshuaj tiv thaiv muaj ntau yam zoo:
- Kev ua haujlwm siab
- Kev xaiv zoo heev
- Tsawg los ntawm - cov khoom tsim
- Fast curing ceev
- Cov khoom ua tau zoo ib yam
Vim tias cov yam ntxwv no, hydrosilylation tau dhau los ua cov thev naus laus zis hauv ntau cov txheej txheem tsim khoom silicone.
Vim li cas DVTMDS siv hauv Platinum Catalyst Systems?
DVTMDS muaj ob lub davhlau ya nyob twg vinyl pawg txuas nrog lub pob txha siloxane. Cov qauv no ua rau nws tsim tshwj xeeb rau kev sib cuam tshuam nrog platinum catalyst systems.

Qhov tseem ceeb ntawm High Purity DVTMDS
Hauv cov ntawv thov platinum catalyst, impurities tuaj yeem cuam tshuam rau kev ua haujlwm catalyst thiab ntev -lub sijhawm ruaj khov.
Vim li no, manufacturers feem ntau them sai sai rau:
Cov ntsiab lus noo noo
Cov dej noo ntau dhau tuaj yeem cuam tshuam kev ruaj khov thiab kev ua haujlwm ntawm kev tsim.
Cov ntsiab lus chloride
Cov tshuaj chloride tsawg feem ntau nyiam rau cov kab mob catalyst rhiab heev.
Purity Consistency
Cov purity zoo ib yam pab txhawb kev tsim cov txiaj ntsig txhim khu kev qha thiab txo cov txheej txheem sib txawv.
Thaum ntsuas DVTMDS rau cov ntawv thov catalyst, qhov zoo sib xws feem ntau suav tias yog qhov tseem ceeb raws li tus nqi nominal purity.
Cov ntawv thov ntawm Platinum Catalyst Systems uas muaj DVTMDS
Liquid Silicone Roj Hmab (LSR)
Siv nyob rau hauv precision molding daim ntaub ntawv yuav tsum tau zoo heev curing tswj thiab cov khoom sib xws.
