Isixazululo Sokulwa Nokuguga se-Polyamide (Nylon, PA)

Ukulwa-ukugugaSisixazululo seI-Polyamide (i-Nylon, PA)

Inayiloni (i-polyamide, i-PA) iyipulasitiki yobunjiniyela enezakhiwo ezinhle kakhulu zomshini nezokucubungula, phakathi kwazo i-PA6 ne-PA66 ziyizinhlobo ezivamile ze-polyamide.

Kodwa-ke, inemikhawulo ekumelaneni nokushisa okuphezulu, ukuqina kombala okungekuhle, futhi ithambekele ekumuncweni komswakama kanye ne-hydrolysis.

Uma sithatha i-PA6 njengesibonelo, lesi sihloko sihlola indlela yokuthuthukisa ukumelana kwayo nokuguga. Izifundo ezihlobene zibonise ukuthi ukusebenza kwe-PA6 kungathuthukiswa kakhulu ngokungeza okufanelekileama-antioxidantkanye nezinye izithasiselo. Ngemva kokuhlolwa kokuchayeka kwe-UV isikhathi eside kanye nokuhlolwa kokuqina kokushisa, lezi zinhlanganisela ezilandelayo zinikeze isivikelo esihle sezakhiwo zemishini nombala we-nylon:

①I-Antioxidant 1098+ I-Antioxidant 626

②I-Antioxidant 245+I-Antioxidant 626

③I-Antioxidant 1098+I-Antioxidant 168

Ukuze kwandiswe isikhathi senkonzo ye-PA, kuvame ukudingeka ukwengeza ezinye izithasiselo. Isibonelo, ukwengeza i-HALS ukuthuthukisa ukuzinza kokukhanya,LS770ingenye yezinketho ezingenzeka ezinomthelela omncane ezimpahleni zemishini. Okwamanje, inkampani yethu ihlinzeka nge-nylon stabilizer esebenza ngemisebenzi eminingi ebizwa ngokuthiLS438, okuyinto ukucutshungulwa okuthuthukisiwe kokuncibilika kwama-polyamides, ukuqiniswa kokushisa kwesikhathi eside kanye nokuzinza kwesithombe, kanye nokuthuthukisa ukushesha kombala.

Ukuze kuthuthukiswe ubumhlophe futhi kugqunywe ukuphuzi, i-TiO2₂, i-ultramarine blue, ama-optical brightening agents, njll. nawo angeziwe ku-Polyamide. I-Optical Brightener KSNInikezwe yinkampani yethu iyisinqumo sekhwalithi ephezulu futhi esingamelana nokushisa okuphezulu.

Ngaphezu kwalokho,i-carbodiimide anti-i-ejenti ye-hydrolysis ingangezwa ukuze ithuthukise ukusebenza kwayo kokulwa ne-hydrolysis futhi yandise isikhathi sayo sokungenisa i-oxidation ngokuxhumanisa nezinye izithasiselo.

Iziphakamiso ezingenhla aziyona isiqondiso sobuchwepheshe, futhi ukusebenza kwangempela kudinga ukunqunywa ngokwemikhuba yabasebenzisi.
