Anti-kukweguraSmhinduro yePolyamide (Nylon, PA)
Nylon (polyamide, PA) ipurasitiki yeinjiniya ine hunhu hwakanaka hwemakanika uye hwekugadzirisa, pakati payo PA6 nePA66 mhando dzepolyamide dzakajairika.
Zvisinei, ine miganhu mukudzivirira kupisa kwakanyanya, kusagadzikana kwemavara, uye inokurumidza kunyudzwa hunyoro uye hydrolysis.
Tichitora PA6 semuenzaniso, chinyorwa chino chinoongorora nzira yekuvandudza kusakwanisa kwayo kukwegura. Zvidzidzo zvine chekuita nazvo zvakaratidza kuti kushanda kwePA6 kunogona kuvandudzwa zvakanyanya nekuwedzera zvakakodzeramishonga inorwisa mabhakitiriyanezvimwe zvinowedzerwa. Mushure mekuyedzwa kwenguva refu kwekuratidzwa kweUV uye kuyedzwa kwekugadzikana kwekupisa, misanganiswa inotevera yakapa dziviriro yakanaka kune hunhu hwemakanika uye ruvara rwenylon:
①Antioxidant 1098+ Antioxidant 626
②Antioxidant 245+Antioxidant 626
③Antioxidant 1098+Antioxidant 168
Kuti PA iwedzere nguva yebasa, zvinowanzo dikanwa kuwedzera zvimwe zvinowedzera. Semuenzaniso, kuwedzera HALS kuti chiedza chigadzikane,LS770ndeimwe yesarudzo dzinogoneka dzisina mhedzisiro yakawanda pahunhu hwemakanika. Panguva iyi, kambani yedu inopa chinodzivirira nylon chinoshanda mabasa akawanda chinonziLS438izvo kugadziriswa kwakavandudzwa kwepolyamides inonyunguduka, kuwedzera kupisa kwenguva refu uye kugadzikana kwemufananidzo, uye kuwedzera kukurumidza kwemavara.
Kuti kucheneswa kuwedzere kuchena uye kuvhare yero, TiO22, ultramarine blue, optical brightening agents, nezvimwewo zvakawedzerwawo kuPolyamide. Optical Brightener KSNChigadzirwa chakapihwa nekambani yedu isarudzo yepamusoro-soro uye inodzivirira kupisa kwakanyanya.
Pamusoro pe,anti-carbodiimide-mumiririri wehydrolysis inogona kuwedzerwa kuti iwedzere kushanda kwayo kwekudzivirira hydrolysis uye kuwedzera nguva yayo yekupinza oxidation nekubatanidza nezvimwe zvinowedzera.
Mazano ari pamusoro apa haasi nhungamiro yehunyanzvi, uye mashandiro chaiwo anofanira kusarudzwa nemaitiro emushandisi.
