Bishyushye kugurisha aromatic polyether polyurethane acrylate kubiti, impapuro na plastike

ZC6203 ni ubwoko bwa polyurethane acrylate.Polyether polyol mu magambo ahinnye nka polyether.Ni oligomer hamwe na ether bond (- ror -) mumurongo wingenzi hamwe nitsinda rirenga bibiri hydroxyl (- OH) mumatsinda yanyuma cyangwa itsinda ryuruhande.Itegurwa na polymerisation yabatangije (ibice birimo hydrogène ikora) hamwe na okiside ya Ethylene (EO), okiside ya propylene (PO), epoxy butane (Bo) imbere ya catalizator.Umusaruro munini wa polyether ni glycerol (glycerol) nkuwatangije na epoxide.Polyoli zitandukanye muri rusange zikorwa muguhindura uburyo bwo kugaburira (kuvanga cyangwa gutandukana), igipimo cya dosiye hamwe nuburyo bwo kugaburira Po na EO.

Igipimo cyacyo cya tekiniki: viscosity ni 40000-70000pa S / 25℃, agaciro ka aside <0.5 (NCO%), imikorere 3 (agaciro ka theoretical), ibara ritagira ibara cyangwa umuhondo umucyo utagaragara;Iki gicuruzwa gifite ibyiza byo gukomera, imbaraga za firime nyinshi, ibikorwa byitwara neza, guhagarika gukomera nibindi.Ikoreshwa cyane muri wino ikiza yoroheje, ibikoresho byo mubiti, gutwikira hasi, gutwikira impapuro, gutwikira plastike, gutera vacuum, gutera ibyuma nibindi bice.

Urunigi nyamukuru rwa zc6203 rurimo ether bond (- ror -), kandi itsinda ryanyuma cyangwa itsinda ryuruhande ririmo oligomers hamwe nitsinda rirenga 2 hydroxyl (- OH).Ikozwe nimpeta ifungura polymerisiyumu yuburemere buke bwa polyole, polyamine cyangwa ibice birimo hydrogène ikora hamwe na olefine ya okiside ikorwa na catalizator.Olefine ya Oxidize ni oxyde ya propylene (okiside ya propylene) na okiside ya Ethylene (okiside ya Ethylene), muri yo oxyde ya propylene ni ngombwa cyane.Uburemere bwa molekile ya polyether hamwe na hydroxyl-propylene glycol na tetrahydroxy-propylene glycol mugukoresha ni 4000-400.Ibisigarira bya polyether bikoreshwa nkibifatika bigomba kuvanaho cataliseri ya alkaline isigara mugihe cya polymerisiyonike, kuko irashobora guhagarika dimerisation ya isocyanates kandi ikagira ingaruka kumiterere yifatizo.
