Kodi Chothandizira cha Polyurethane N'chiyani?
Tanthauzo la Chothandizira
Chothandizira cha polyurethane ndi mankhwala omwe amathandiza kufulumizitsa kuyanjana pakati pa isocyanate ndi polyol. Kuyanjana kumeneku kumapanga polyurethane, chinthu chomwe chimagwiritsidwa ntchito muzinthu zambiri monga thovu, zokutira, ndi zomatira. Ma catalyst ambiri a polyurethane ndi ma tertiary amines. Ma mine awa amapangitsa kuti gawo la diol likhale logwirizana kwambiri, zomwe zimathandiza kuwongolera momwe polyurethane imapangikira.
- Ma catalyst a polyurethane akhoza kugawidwa m'magulu a amine oyambira ndi a acidic.
- Yapamwambazinthu zoyambitsa aminekumawonjezera kuchuluka kwa ma nucleophilicity a diol, zomwe zimapangitsa kuti izi zichitike mwachangu komanso moyenera.
Opanga amagwiritsa ntchito ma catalyst a polyurethane kuti atsogolere njira ya mankhwala. Izi zimatsimikizira kuti chinthu chomaliza chili ndi makhalidwe oyenera, monga kusinthasintha kapena kuuma.
Ma catalyst a polyurethane amachita gawo lofunika kwambiri pakuwonetsetsa kuti zomwe zimachitika zimachitika mwachangu komanso bwino. Popanda iwo, njirayi ingakhale yochedwa komanso yosayembekezereka.
Udindo mu Kupanga Polyurethane
Ntchito ya ma catalyst a polyurethane pakupanga ndi yofunika kwambiri. Amachepetsa mphamvu yogwirira ntchito yomwe imafunika pakuchita pakati pa isocyanates ndi polyols. Izi zikutanthauza kuti kuchitapo kanthu kumachitika mwachangu komanso kutentha kochepa. Ma catalyst amalumikizana ndi ma reactants, ndikupanga ma complexes apakati omwe amapangitsa kuti urethane bonds ipangidwe mosavuta.
