Polyether polyurethane acrylate yopangira zokutira pulasitiki

Mtengo wa ZC6202

Product ZC6202 ndi mtundu wamakampani.Dzina lake la mankhwala ndi polyether polyurethane acrylate.Ndi madzi opanda mtundu kapena achikasu owoneka bwino komanso osinthasintha komanso amamatira.Amagwiritsidwa ntchito makamaka pamapepala, zokutira pulasitiki ndi zoyambira zamatabwa.Aromatic polyurethane acrylate

Onjezani poliyesitala (polyester) diol ndi polymerization inhibitor mu botolo lina la doko lokhala ndi makina oyambitsa, thermometer ndi chubu la condenser, yambitsani mofanana, kenaka yonjezerani TDI, kwezani kutentha kwa 70-80 ℃ kuti muchite kwa maola 1.5, zindikirani mtengo wa NCO, kenaka yonjezerani hydroxyethyl acrylate (hydroxypropyl acrylate), yonjezerani chothandizira, pitirizani kuchitapo kanthu kwa maola a 3, ndikuwona kuti mtengo wa NCO ndi wofanana ndi 0. Kukhuthala kwa acrylate onunkhira a polyurethane anayesedwa ndi zitsanzo, ndipo ntchito ya onunkhira ya polyurethane acrylate inayesedwa. powonjezera 3% - 4% photoinitiato.Chonde sungani malo ozizira kapena owuma, ndipo pewani dzuwa ndi kutentha;Kutentha kosungirako sikudutsa 40 ºC, malo osungiramo zinthu zabwinobwino kwa miyezi 6 yosachepera.

Yoyambitsidwa ndi polyethylene glycol (PEG, MW 1000) ε- Caprolactone (ε- Gawo lofewa la polyether ester block copolymer diol (pCEC) linakonzedwa ndi kutsegulidwa kwa mphete, kuchitapo ndi diisocyanate (toluene diisocyanate kapena diphenylmethane diisocyanate kenaka hydroxynate) kuchiritsidwa kuti apeze polyether ester polyurethane acrylate material (PUA) Mapangidwe ndi mapangidwe a PUA anali odziwika Zotsatira zake zikuwonetsa kuti kuwonjezeka kwa gawo la PCL kungathe kupititsa patsogolo crystallinity ya zinthu za PUA, koma kuchepetsa kuyamwa kwa madzi ndi kuwonongeka kwa madzi Mlingo wa enzymatic hydrolysis wa PUA unali wapamwamba kuposa zomwe za PUA Pcec2000-tdi zili ndi hydrophilicity yabwino kwambiri komanso kuwononga magwiridwe antchito.Mayamwidwe amadzi ndi okwera kwambiri mpaka 65.24% m'maola 72 ndipo amatha kuwonongeka kwathunthu mu njira ya enzyme mkati mwa masabata a 11 Mtundu uwu wa zinthu za PUA uli ndi kuthekera kogwiritsidwa ntchito pazinthu zopanga minofu.
