stabilisateur
Stabilisateur yumucyo ikoreshwa mukurinda plastiki nibindi bikoresho kwangirika igihe kirekire - igihe cyo guhura nimirasire ya ultraviolet. Kumenyekanisha plastike kumirasire ya ultraviolet ituruka kumirasire yizuba itangira kwangirika binyuze muburyo bwo gufotora. Ibi birashobora kugira ingaruka zitari nke zirimo impinduka mumiterere (amabara, ihinduka ryumucyo na / cyangwa kwiruka), kugabanuka kumiterere yubukanishi no gushiraho inenge zigaragara nkibice. Amatara ya Fluorescent akoreshwa mu gucana mu nzu nayo asohora imirasire ya UV, ariko kurwego rwo hasi cyane kuruta izuba.
Nko kubijyanye na okiside yumuriro, fotooxidation ninzira yumunyururu urimo radicals yubusa hamwe nabahuza hydroperoxide. Photostabilisers irabuza iki gikorwa mugukata abahuza reaction cyangwa mukurwanya imishwarara yangiza UV.
Inzitizi zibangamira urumuri rwa amine (HALS) zikora cyane cyane mugushakisha imiyoboro yubusa muburyo bwo gufotora. HALS ifite akamaro kanini muguhindura urumuri rwa polyolefine, polymers styrenic hamwe na plastiki yubuhanga.
Imashini ya Ultraviolet (UV) ikora mukurinda imbere ibice bya plastike kwangiza imirasire ya UV. Ibicuruzwa birangwa no gukurura cyane UV hamwe nurwego rwo hejuru rwo gufotora. Imashini ya UV ifite akamaro muguhindura plastike nyinshi, zirimo PVC na plastiki yubuhanga. Zikoreshwa kandi mubikoresho byo gupakira plastike kugirango birinde ibintu bipfunyika imirasire ya UV.
Ihuriro rya HALS na UV ikurura akenshi igaragaza imikorere ikomatanya hejuru yumucyo wonyine.
