Hot sayar da aromatic polyether polyurethane acrylate ga itace, takarda da filastik coatings

ZC6203 shine nau'in polyether polyurethane acrylate.Polyether polyol an rage shi azaman polyether.Yana da oligomer tare da ether bond (- ror -) a cikin babban sarkar kuma fiye da ƙungiyoyi biyu na hydroxyl (- OH) a cikin rukuni na ƙarshe ko rukuni na gefe.An shirya shi ta hanyar polymerization na mai farawa (haɗin da ke dauke da ƙungiyar hydrogen mai aiki) tare da ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) a gaban mai kara kuzari.Mafi girman fitarwa na polyether shine glycerol (glycerol) azaman mai haɓakawa da epoxide.Ana samar da polyether polyols daban-daban ta hanyar canza yanayin ciyarwa (gauraye ko raba), rabon sashi da tsarin ciyarwar Po da EO.

Indexididdigar fasaha: danko shine 40000-70000pa S / 25℃, darajar acid <0.5 (NCO%), aikin 3 (ƙimar ka'idar), ruwa mara launi ko launin rawaya a cikin bayyanar;Wannan samfurin yana da abũbuwan amfãni daga mai kyau tauri, high film ƙarfi, high dauki aiki, m block da sauransu.An yadu amfani da haske curing tawada, itace furniture, bene shafi, takarda shafi, filastik shafi, injin spraying, karfe shafi da sauran filayen.

Babban sarkar zc6203 ya ƙunshi ether bond (- ror -), kuma ƙungiyar ƙarshe ko ƙungiyar gefe ta ƙunshi oligomers tare da ƙungiyoyin hydroxyl fiye da 2 (- OH).An kafa shi ta hanyar buɗe zobe ta hanyar polymerization na ƙananan ƙwayoyin ƙwayoyin polyols, polyamines ko mahadi masu ɗauke da hydrogen mai aiki tare da olefins oxidized a ƙarƙashin aikin masu kara kuzari.Oxidized olefins yawanci propylene oxide (propylene oxide) da ethylene oxide (etylene oxide), wanda propylene oxide ne mafi muhimmanci.Nauyin kwayoyin halitta na polyether tare da hydroxyl-propylene glycol da tetrahydroxy-propylene glycol a cikin amfani na kowa shine 4000-400.Polyether resins da aka yi amfani da su azaman adhesives ya kamata cire ragowar alkaline masu haɓakawa yayin polymerization, saboda suna iya haɓaka dimerization na isocyanates kuma suna shafar ingancin adhesives.
