Maitiro ekuitaSarudzaiyoAzvakakodzeraAhaioksijeni？
Kusarudza antioxidant yakakodzera idanho guru rekuvandudza kugara kwenguva refu, chitarisiko uye mashandiro epolymer. Izvi zvinoda kutariswa kwakazara kwezvinhu zvakawanda zvakaita sehunhu hwemakemikari epolymer pachayo, mamiriro ekugadzirisa, nharaunda yekushandisa uye mitemo yekudzivirira nharaunda.
Polyolefini(senge polyethylene ne polypropylene) zvinokurumidza kuora kwe oxidative yekupisa, zvichida kuti ma antioxidants ekutanga (senge phenols) abate ma free radicals uye ma antioxidants ekuwedzera (senge phosphites) kuti abvise hydroperoxide.
PVCKuora kwemuviri kunonyanya kukonzerwa neionization, uye zvichienzaniswa nepolyolefins, vagadziri vePVC havadi ma antioxidants akawanda. Parizvino, ma antioxidants anoshandiswa zvakanyanya paPVC anosanganisiraAO1076, AO2246, nezvimwewo.
Mapurasitiki einjiniya(PA, PC, PPS) zvinowanzo gadziriswa pakupisa kwakanyanya uye zvinodama antioxidants anodzivirira kupisakudzivirira kutsvuka kwebvudzi uye kurasikirwa nesimba.
①Kuti ugadzire mhando dzinopisa zvakanyanya (>280 ℃), zvinokurudzirwa kusarudza mhando dzisingachinji zvakanyanya uye dzisingapindi kupisa zvakanyanya.
②Kuti munhu agare ari panze kwenguva yakareba, anofanirwa kushandisa nzira yekudzivirira UV, senge phenolic compounds uyezvinonwisa UV.
③Chenjerera kuti zvinhu zvienderane uye usadonhedze mvura. Pamusoro pezvo, maamine antioxidants haadziviriri ruvara zvakanyanya.
④Kusanganiswa kweantioxidant huru neantioxidant inobatsira kunogona kuvandudza zvakanyanya mhedzisiro yekudzivirira kukwegura.
Muchidimbu, kushandisa ma antioxidants chete hakuna kukwana kugadzirisa mamiriro akasiyana-siyana ekushandiswa, uye kubatana kwezvinowedzera zvakawanda isarudzo iri nani.
Taura nesu kuti uwane rumwe ruzivo!
