Kugulitsa kotentha kwa polyether polyurethane acrylate yamatabwa, mapepala ndi zokutira zapulasitiki

ZC6203 ndi polyether mtundu polyurethane acrylate.Polyether polyol imafupikitsidwa ngati polyether.Ndi oligomer yokhala ndi ether bond (- ror -) mu unyolo waukulu ndi magulu oposa awiri a hydroxyl (- OH) mu gulu lomaliza kapena gulu lakumbali.Imakonzedwa ndi polymerization wa initiator (gawo munali yogwira hydrogen gulu) ndi ethylene okusayidi (EO), propylene okusayidi (PO), epoxy butane (Bo) pamaso chothandizira.Kutulutsa kwakukulu kwa polyether ndi glycerol (glycerol) monga initiator ndi epoxide.Mitundu yosiyanasiyana ya polyether polyether imapangidwa posintha njira yodyetsera (yosakanikirana kapena yosiyana), chiŵerengero cha mlingo ndi dongosolo la chakudya cha Po ndi EO.

ukadaulo wake index: mamasukidwe akayendedwe ndi 40000-70000pa S / 25℃, mtengo wa asidi <0.5 (NCO%), magwiridwe antchito 3 (mtengo woyerekeza), mawonekedwe amadzimadzi owoneka bwino opanda mtundu kapena achikasu;Mankhwalawa ali ndi ubwino wa kulimba kwabwino, mphamvu yapamwamba ya filimu, zochitika zapamwamba, chipika cholimba ndi zina zotero.Amagwiritsidwa ntchito kwambiri pakuchiritsa inki, mipando yamatabwa, zokutira pansi, zokutira zamapepala, zokutira pulasitiki, kupopera mbewu mankhwalawa, zokutira zitsulo ndi zina.

Unyolo waukulu wa zc6203 uli ndi mgwirizano wa ether (- ror -), ndipo gulu lomaliza kapena gulu la mbali lili ndi oligomers ndi magulu oposa 2 hydroxyl (- OH).Amapangidwa ndi mphete kutsegula polymerization wa otsika maselo kulemera polyols, polyamines kapena mankhwala munali haidrojeni yogwira ndi oxidized olefins pansi zochita za chothandizira.Ma olefini okhala ndi okosijeni makamaka ndi propylene oxide (propylene oxide) ndi ethylene oxide (ethylene oxide), yomwe propylene oxide ndiyofunikira kwambiri.Kulemera kwa molekyulu ya polyether yokhala ndi hydroxyl-propylene glycol ndi tetrahydroxy-propylene glycol yogwiritsidwa ntchito wamba ndi 4000-400.Utomoni wa polyether womwe umagwiritsidwa ntchito ngati zomatira uyenera kuchotsa zotsalira zamchere zamchere panthawi ya polymerization, chifukwa zimatha kuyambitsa dimerization ya isocyanates ndikusokoneza zomatira.
