Ungaita seiSarudzatheAzvakakodzeraAntioxidant?
Kusarudza yakakodzera antioxidant inhanho yakakosha yekuvandudza kusimba, kutaridzika uye kushanda kwepolymer. Izvi zvinoda kutariswa kwakadzama kwezvinhu zvakawanda senge kemikari yepolymer pachayo, kugadzirisa mamiriro, kuguma kwekushandisa nharaunda uye mitemo yekudzivirira kwezvakatipoteredza.
Polyolefins(yakadai se polyethylene uye polypropylene) inotarirwa nekupisa oxidative degradation, inoda primary antioxidants (senge phenols) kutora mahara radicals uye anobatsira antioxidants (senge phosphites) kuti iparadze hydroperoxide.
PVC's degradation inonyanya kuenderana neionization, uye zvichienzaniswa ne polyolefins, vagadziri vePVC vane zvishoma kudiwa kwema antioxidants. Parizvino, inowanzoshandiswa antioxidants yePVC inosanganisiraAO1076, AO2246, nezvimwewo.
Injiniya mapurasitiki(PA, PC, PPS) inowanzogadziriswa pakupisa kwakanyanya uye inodakupisa-resistant antioxidantskudzivirira kutsvuka uye kupera simba.
①Pamusoro-yepamusoro-tembiricha yekugadzirisa mamiriro (> 280 ℃), zvinokurudzirwa kusarudza mhando dzine yakaderera kuderera uye yakakwirira tembiricha kuramba.
②Nekuda kwekuratidzwa kwekunze kwenguva refu, synergistic anti-UV system inodiwa, senge phenolic compounds uye.UV absorbers.
③Cherechedza kuenderana uye kudzivirira kunaya. Uye zvakare, amine antioxidants ine isina kusimba yekudzivirira kwemavara.
④Kusanganiswa kweiyo huru antioxidant uye yekubatsira antioxidant inogona kuvandudza zvakanyanya anti-kuchembera maitiro.
Muchidimbu, kushandiswa kwema antioxidants chete hakuna kukwana kutarisana neakasiyana mashandisirwo mamiriro, uye kurongeka kweakawanda ekuwedzera isarudzo iri nani.
Bata nesu kuti uwane rumwe ruzivo!
