Te hoko wera polyether polyurethane acrylate mo te rakau, pepa me nga paninga kirihou

ZCKo te 6203 he momo polyurethane acrylate polyether.Ko te polyether polyol ka whakapotohia hei polyether.He oligomer me te here ether (- ror -) i te mekameka matua me te neke atu i te rua nga roopu hydroxyl (- OH) i te roopu mutunga, te roopu taha ranei.Ka mahia ma te polymerization o te kaitakawaenga (puhui kei roto te roopu hauwai kaha) me te ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) i te aroaro o te whakakōkī.Ko te putanga nui rawa atu o te polyether ko te glycerol (glycerol) hei kaikawe me te epoxide.He maha nga momo polyether polyols ka puta ma te whakarereke i te aratau whangai (whakaranu, wehea ranei), inenga inenga me te raupapa whangai a Po me EO.

Ko tana tohu hangarau: 40000-70000pa S / 25 te pokey℃, uara waikawa <0.5 (NCO%), mahi 3 (uara ariā), he wai marama kore tae, he kowhai ranei te ahua;Ko tenei hua nga painga o te pakari pai, te kaha o te kiriata teitei, te mahi tauhohenga teitei, te poraka pakari me etahi atu.Kei te whakamahia nuitia i roto i te waituhi whakaora marama, taonga rakau, paninga papa, paninga pepa, paninga kirihou, rehu korehau, paninga whakarewa me etahi atu mara.

Kei roto i te mekameka matua o zc6203 te here ether (- ror -), me te roopu mutunga, te roopu taha ranei kei roto i nga oligomer me te neke atu i te 2 nga roopu hydroxyl (- OH).He mea hanga na roto i te polymerization whakatuwhera whakakai o nga polyols iti ngota ngota, polyamines me nga pūhui kei roto i te hauwai kaha me nga olefins oxidized i raro i te mahi a te whakakōkī.Ko te nuinga o nga waikura kua whakahaehae he propylene oxide (propylene oxide) me te ethylene oxide (ethylene oxide), ko te propylene oxide te mea nui.Ko te taumaha ngota o te polyether me te hydroxyl-propylene glycol me te tetrahydroxy-propylene glycol e whakamahia ana he 4000-400.Ko nga kapia polyether e whakamahia ana hei whakapiringa me tango nga toenga kawakore i te wa o te polymerization, na te mea ka taea e ratou te whakakorikori i te dimerization o te isocyanates me te pa ki te kounga o te whakapiri.
