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 maitiro ekuvandudza kuramba kwayo kukwegura. Zvidzidzo zvine chekuita nazvo zvakaratidza kuti kushanda kwePA6 kunogona kuvandudzwa zvakanyanya nekuwedzera ma antioxidants akakodzera nezvimwe zvinowedzera. 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 chinonziLS438, izvo zvakavandudza kugadziriswa kwekunyunguduka kwepolyamides, zvakawedzera kupisa kwenguva refu uye kugadzikana kwemufananidzo, uye zvinovandudza kukurumidza kwemavara.

Kuti kuchena kuwedzere kuchena uye kufukidza yero, TiO2, ultramarine blue, optical brightening agents, nezvimwewo zvakawedzerwawo muPolyamide.Optical Brightener KSNChigadzirwa chakapihwa nekambani yedu isarudzo yepamusoro-soro uye inodzivirira kupisa kwakanyanya.

Pamusoro pe,mumiririri we anti-hydrolysis we carbodiimideinogona 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.
