Light Stabilizer-944 CAS 70624-18-9 ni iki?

Ikirahure cy'urumuri UV-944 gifite ubushobozi bwo guhangana no gukuramo ibintu, cyane cyane ku bicuruzwa bito, nk'imigozi na za firime; gishobora kandi kunoza ubushobozi bwo guhangana no gusaza kwa ogisijeni mu bushyuhe bw'ibikoresho. Ikirahure cy'urumuri HS-944 ni uduce tw'umweru cyangwa umuhondo woroshye cyangwa ifu, aho gushonga ni 100-135°C, uburemere bwa molekile 2000-3100, gifite ubushobozi bwo guhuza neza, ubushobozi bwo guhangana no gukuramo ibintu kandi kikaba gito. Kubera ko UV-944 ari ikikirahure cy'urumuri kinini, kandi molekile ikaba irimo methylate nyinshi gusa, irakomera iyo ivuwe na ogisijeni ishyushye.

Porogaramu

Light Stabilizer-944 ikoreshwa mu ifirime ya polyethylene ifite ubucucike buke, fibre ya polypropylene, kaseti ya polypropylene, ifirime ya EVA, ABS, polystyrene no mu bipfunyika by'ibiribwa. Light stabilizer HS-944 ikoreshwa mu ifirime ya amine igabanya ubucucike.

Ibyiza byacu

1. Ingaruka nziza zo kubungabunga urumuri: UV-944 ishobora kurinda neza ibikoresho bya polymer kwangirika k'urumuri rwa ultraviolet no kwangirika k'ubushyuhe no kwangirika k'ubushyuhe guterwa no gusaza k'ubushyuhe igihe kirekire. Ingaruka zayo zo kubungabunga urumuri ziruta kure iz'ibikoresho bigabanya imirabyo ya ultraviolet n'ibikoresho bigabanya imirabyo bya nikeli, cyane cyane mu buryo bw'ibara aho ingaruka zigaragara cyane.

2. Ikorana neza kandi itunganywa neza: Ni ibikoresho by'umuhondo woroshye kandi bifite ubukana buke. Ikorana neza n'ibikoresho bitandukanye bya polymer nka PP, LDPE, HDPE, na PVC. Ishobora gukwirakwizwa byoroshye muri matrix ya polymer nta ngaruka ku mucyo n'ibara bya resin, kandi ifite imikorere myiza yo gutunganya.

3. Uburyo bwinshi bwo gukoresha kandi bwizewe: UV-944 ikwiriye ubwoko butandukanye bw'ibikoresho nka za firime, fibre, n'ibindi bikoresho binini, kandi ishobora gukoreshwa kuri polimeri nyinshi zirimo polyolefins, polyurethanes, na polyamides. Hagati aho, yemejwe na FDA kandi ishobora gukoreshwa mu gukoresha ibiryo, igaragaza urwego runaka rw'umutekano.
