Ngā Whakamahinga o te Waikawa Propionicinfo@pulisichem.cn
Ko te Waikawa Propionic, ko tōna ingoa matū ko te waikawa acetyl propionic me te tātai ngota C₅H₈O₂, he wai mārama, kāore he tae, he reka kawa, ā, he ngāwari te wairewa ki te wai me te nuinga o ngā whakarewa waro. He mahi ahurei tā tēnei matū i roto i ngā tauhohenga whakapūtanga waikawa ngako kukū. Ko ōna āhuatanga ā-tinana—te pūwāhi kohua 215°C me te pūwāhi mura 96°C—e whakarato ana i te pumau i roto i ngā tukanga pāmahana teitei. Hei takawaenga matū nui, ko te noho tahi o ngā rōpū carboxyl me te ketone i roto i tōna hanganga ngota ka taea te mahi takirua i roto i ngā tauhohenga whakapūtanga me te whakapūtanga whakawhiti.
I roto i te mara o te hanga rauropi, ka whai wāhi te Waikawa Propionic ki ngā tauhohenga hononga-whiti hei whakarite i ngā rauemi polymer. Ina whakakotahihia ki te epichlorohydrin i raro i ngā āhuatanga kawakore, ka hangaia he kapia thermosetting e whakamahia ana i roto i ngā paninga ārai-waikura moana, ā, ka taea e ngā hua kua rongoatia te tu atu i te waikura mā te 5% te kukū o te wai moana tae atu ki te 300 hāora. Hei wāhanga comonomer o ngā monomers acrylate, mā te tāpiri i te 15% vinyl propionyl acetate ka taea te whakanui ake i te piri o ngā paninga polyacrylate emulsion ki te 4.5 MPa me te whakaroa i te ātete huarere o waho ki te 8 tau.
