Kodi CAS 3290-92-4 Trimethylolpropane trimethacrylate ndi chiyani?

Trimethylolpropane triacrylate (TMPTA) ndi mtundu wamtundu wa trifunctional monomer wokhala ndi mamasukidwe apamwamba kuposa ma monofunctional and bifunctional monomers. Komabe, poyerekeza ndi multifunctional monomers, ali otsika mamasukidwe akayendedwe ndi solubility wabwino. Monomer iyi imatha kupereka kuthamanga kwa machiritso komanso kachulukidwe kakang'ono kwambiri, kupanga filimu yochiritsa yokhala ndi zosungunulira zabwino kwambiri, kukana kukanda kolimba, komanso kuphulika. Mtengo wake ndi wochepa, ndipo ngakhale uli ndi zowawa pakhungu, ukadali monomer yomwe imagwiritsidwa ntchito kwambiri.

Kugwiritsa ntchito

1.TMPTMA angagwiritsidwe ntchito ngati crosslinking thandizo kwa peroxide crosslinking, oyenera kusakaniza mphira cis-1,4-polybutadiene, ethylene propylene diene monoma, ethylene propylene diene monoma, isoprene mphira, butyl ndi nitrile mphira.

2. Vulcanizing wothandizila: Mukamagwiritsa ntchito peroxide kuti vulcanization wa labala kupanga, TMPTMA akhoza kusintha dzimbiri kukana, kukana kukalamba, ndi kuuma. Kutentha kwa kutentha: TMPTMA imakhala ndi plasticizing pamene ikusakaniza, ndipo zotsatira zake zowumitsa panthawi ya vulcanization zingagwiritsidwe ntchito pa NBR, DM, ndi rabara ya acrylic.

3. Crosslinking agent: TMPTMA ikhoza kuchepetsa mlingo wa ma radiation, kuchepetsa nthawi ya ma radiation, kupititsa patsogolo kachulukidwe kameneka, ndipo imakhala ndi makhalidwe monga otsika kwambiri, digiri yapamwamba yolumikizira, kuthamanga kwa nthunzi yochepa, komanso kuthamanga kwachangu. Itha kugwiritsidwa ntchito pojambula inki ndi zida za photopolymer.
