Nylon (polyamide, PA) ni pulasitiki y’ubuhanga ifite ubushobozi bwiza bwo gutunganya no gutunganya, muri yo PA6 na PA66 ni ubwoko busanzwe bwa polyamide.

Ariko, ifite imbogamizi mu guhangana n'ubushyuhe bwinshi, kudahinduka kw'amabara, kandi ikunze kwinjizwamo ubushuhe no gushonga k'amazi.

Dufashe urugero rwa PA6, iyi nkuru irasuzuma uburyo bwo kongera ubushobozi bwayo bwo kudasaza. Ubushakashatsi bujyanye n'ibyo bwagaragaje ko imikorere ya PA6 ishobora kunozwa cyane hakongerwamo antioxydants zikwiye n'izindi nyongeramusaruro. Nyuma yo gupimwa igihe kirekire ku bijyanye n'imirasire ya UV no gupimwa ubushyuhe burambye, ibi bikurikira byatanze uburinzi bwiza ku miterere n'ibara bya nylon:

①Antioxydant 1098 + Antioxydant 626

②Antioxydant 245 + Antioxydant 626

③Antioxydant 1098 + Antioxydant 168

Kugira ngo PA yongere igihe cyo gukora, akenshi biba ngombwa kongeramo izindi nyongera. Urugero, kongeramo HALS kugira ngo urumuri rukomeze gukomera,LS770ni imwe mu mahitamo ashoboka kandi nta ngaruka nyinshi ku miterere y'imashini. Hagati aho, ikigo cyacu gitanga icyuma gikomeza gukora nylon cyitwaLS438, byanogeje uburyo bwo gushonga kwa polyamides, byongera ubushyuhe n'ubudahinduka bw'amafoto mu gihe kirekire, kandi byongera umuvuduko w'amabara.

Kugira ngo hongerwe umweru kandi hatwikirirwe umuhondo, TiO2, ubururu bwa ultramarine, ibikoresho byo gukaranga urumuri, nibindi byongewe muri Polyamide.Imashini ikoresha urumuri (Optical Brightener KSN)Itangwa n'ikigo cyacu ni amahitamo meza kandi arwanya ubushyuhe bwinshi.

Byongeye kandi,umuti urwanya karbodiimide urwanya hydrolysisishobora kongerwamo kugira ngo yongere imikorere yayo yo kurwanya hydrolysis no kongera igihe cyo kuyikoresha mu guhuza n'izindi nyongeramusaruro.

Ibitekerezo byavuzwe haruguru ntabwo ari ubuyobozi bwa tekiniki, kandi imikorere nyayo igomba kugenwa n'uburyo abakoresha bakoresha.
