Umuti urwanya gusaza wa Polyamide (Nylon, PA)

Anti-gusazaSigisubizo cyaPolyamide (Nylon, PA)

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 kunoza ubushobozi bwayo bwo kudasaza. Ubushakashatsi bujyanye n'ibyo bwagaragaje ko imikorere ya PA6 ishobora kunozwa cyane iyo hongewemo uburyo bukwiyeantioxydantsn'ibindi bivange. Nyuma yo gupimwa igihe kirekire ku bijyanye n'imirasire ya UV no gupimwa uburyo ubushyuhe buhagaze, 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, icyo kunoza uburyo bwo gutunganya polyamides, kongera ubushyuhe n'ubudahinduka bw'amafoto mu gihe kirekire, no kunoza uburyo amabara yihuta.

Kugira ngo wongere umweru kandi utwikire umuhondo, TiO2₂, ubururu bwa ultramarine, ibikoresho byo gukabya by'urumuri, nibindi nabyo byongewe kuri Polyamide. Imashini ikoresha urumuri (Optical Brightener KSN)Itangwa n'ikigo cyacu ni amahitamo meza kandi arwanya ubushyuhe bwinshi.

Byongeye kandi,anti-kabodiimide-umusemburo wa hydrolysis ishobora 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.
