Chimassorb 944 Cas 71878-19-8 ke eng?

Chimassorb 944 (CAS 71878-19-8) ke sesebelisoa se phahameng sa ho tsitsisa khanya ea amine se thibelang boima ba limolek'hule (HALS).

Motsoako oa UV 944 ke sesebelisoa sa ho tiisa khanya ea amine se nang le boima bo phahameng ba limolek'hule se entsoeng ka polymer, se nang le ho feto-fetoha ho tlase, khanyetso ea ho falla, le khanyetso ea mocheso o phahameng. Lihlopha tsa amine tse nang le khanyetso sebopehong sa lik'hemik'hale sa UV 944 li ka tšoara li-free radical ka katleho, ka hona li bapala karolo ho tiiseng khanya.

Bokgoni bo phahameng ba polymeric bo sitisitse ho tsitsisa lesedi la amine, ho fokola ha pherekano, ho falla ho tlase, botsitso ba mocheso le phello ya ho thibela oxidation, e sebetsa mmoho le di-antioxidants le di-absorber tsa UV. UV Absorber 944 e ka sebediswa ho di-polyolefin, di-copolymer tsa olefin, empa hape le bakeng sa di-complex tsa polyphenylene ether, polyoxymethylene, di-amides, di-PVC tse bonolo le tse thata le metswako ya PVC.

Kopo

Chimassorb 944 e ka ntlafatsa botsitso ba leseli la lihlahisoa tse tšesaane ka katleho, haholo-holo lihlahisoa tsa faeba le filimi. UV 944 e boetse e loketse lihlahisoa tse teteaneng tse tšesaane le lihlahisoa tsa polyethylene.

Masimo a tshebediso ya UV Absorber 944 a kenyeletsa dipolasetiki tsa polyolefin (tse kang PP, PE), di-copolymer tsa olefin (tse kang EVA), le metswako ya polypropylene (PP) le di-elastomer, jj. Ho phaella moo, UV Absorber 944 e ka boela ya sebediswa ho polyoxymethylene (POM), polyamide (PA), polyurethane (PU), PVC e tenyetsehang le e tiileng, le metswako ya PVC. Chimassorb 944 e boetse e sebetsa haholo bakeng sa ditshebediso tse ikgethang tsa di-elastomer le dikhomaretsi tse thehilweng ho styrene.
