Chimassorb 944 Cas 71878-19-8 ni iki?

Chimassorb 944 (CAS 71878-19-8) ni umuti ugabanya uburemere bw'urumuri rwa amine (HALS) utuma uruhu rw'umurabyo rudakomeza kwiyongera.

UV Absorber 944 ni igikoresho gipima ubushyuhe bw'urumuri rwa amine gifite uburemere buhanitse kandi gitera imbaraga, gifite ubushyuhe buke, kirwanya kwimuka, kandi kirwanya ubushyuhe bwinshi. Amatsinda ya amine afite ubushyuhe buke mu miterere ya UV 944 ashobora gufata neza radicals yigenga, bityo akagira uruhare mu gutuma urumuri rudahinduka.

Uburyo bworoshye bwo gukoresha polymeric bwabujije amine kutangiza urumuri, kugabanuka cyane kw'ingufu, kugenda guke, kudahindagurika k'ubushyuhe no kurwanya oxidation, bukorana na antioxydants na UV absorbers. UV Absorber 944 ishobora gukoreshwa kuri polyolefins, olefin copolymers, ariko kandi no kuri polyphenylene ether complexes, polyoxymethylene, amides, PVC yoroshye kandi ikomeye na PVC blends.

Porogaramu

Chimassorb 944 ishobora kongera urumuri rw'ibicuruzwa bito cyane cyane fibre na filime. UV 944 ikwiriye kandi ku bicuruzwa binini biva mu bice bitandukanye n'ibikomoka kuri polyethylene.

Ahantu hakoreshwa UV Absorber 944 harimo pulasitiki ya polyolefin (nka PP, PE), olefin copolymers (nka EVA), n'ibivanze bya polypropylene (PP) na elastomers, nibindi. Byongeye kandi, UV Absorber 944 ishobora no gukoreshwa muri polyoxymethylene (POM), polyamide (PA), polyurethane (PU), PVC yoroshye kandi ikomeye, na PVC. Chimassorb 944 nayo ifite akamaro cyane mu gukoresha elastomers na kole zishingiye kuri styrene.

Ibiranga

✅Chimassorb 944 ifite ubushobozi bwo kudahinduka k'urumuri kandi ishobora gukumira kwangirika, ihinduka ry'ibara no kwangirika kwa pulasitiki biterwa n'imirasire ya ultraviolet.
✅UV Absorber 944 ifite ubushobozi bwiza bwo kurwanya gukurura kandi ntishobora kwimuka iva muri pulasitiki mu gihe ikoreshwa igihe kirekire.
✅UV 944 ifite ubushobozi bwo guhuza neza kandi ishobora gukwirakwizwa mu mubiri wa pulasitiki nta ngaruka ku mikorere yayo ndetse n'imiterere yayo.
