Ko te Whakapakari i te waahanga II
Te paitini He iti te paitini whakapeka o te methyl methacrylate.Kua kitea te irirangi o te kiri, te kanohi, me te rua o te ihu i roto i nga kiore me nga rapeti kua kitea ki te nui o te methyl methacrylate.Ko te matū he kiri ngawari ki nga kararehe.Ko te paanga ka kitea i te nuinga o te waa i te iti o te kukū i muri i te tukunga o te manawa ki te methyl methacrylate ko te irirangi o te kohao nasal.Ko nga paanga ki te whatukuhu me te ate i runga i nga kohinga teitei kua panuitia ano.
Whakaorangia ki tetahi waahi makariri, maroke, he pai te hau, me te pupuri i te mahana i raro i te 30 ° C.
Rokiroki ki te waahi makariri.Puritia te ipu kia mau ki te hau ka rongoa ki tetahi wahi maroke, whai hau.
