Iyini iChimassorb 944 Cas 71878-19-8?

I-Chimassorb 944 (CAS 71878-19-8) iyi-molecule ephezulu enesisindo esivinjiwe se-amine light stabilizer (HALS).

I-UV Absorber 944 iyi-polymerized high-molecular-weight inhibitory amine stabilizer, equkethe ukuguquguquka okuphansi, ukumelana nokufuduka, kanye nokumelana nokushisa okuphezulu. Amaqembu e-amine avinjelwe esakhiweni samakhemikhali se-UV 944 angabamba ngempumelelo ama-free radicals, ngaleyo ndlela adlale indima ekuzinziseni ukukhanya.

Ukusebenza kahle kwe-polymeric kuvimbele ukuzinza kokukhanya kwe-amine, ukuguquguquka okuphansi, ukufuduka okuphansi, ukuzinza kokushisa kanye nomphumela wokulwa ne-oxidation, kuhambisana nama-antioxidants kanye nezifutho ze-UV. I-UV Absorber 944 ingasetshenziswa kuma-polyolefins, ama-olefin copolymers, kodwa futhi nakuma-polyphenylene ether complexes, i-polyoxymethylene, ama-amides, ama-PVC athambile futhi aqinile kanye nama-PVC blends.

Isicelo

I-Chimassorb 944 ingathuthukisa ngempumelelo ukuzinza kokukhanya kwemikhiqizo emincane, ikakhulukazi imikhiqizo yefayibha nefilimu. I-UV 944 ifaneleka futhi emikhiqizweni ebanzi yezingxenye kanye nemikhiqizo ye-polyethylene.

Izinkambu zokusetshenziswa kwe-UV Absorber 944 zifaka phakathi amapulasitiki e-polyolefin (njenge-PP, i-PE), ama-olefin copolymers (njenge-EVA), kanye nezingxube ze-polypropylene (PP) kanye nama-elastomers, njll. Ngaphezu kwalokho, i-UV Absorber 944 ingasetshenziswa futhi ezingxubeni ze-polyoxymethylene (POM), i-polyamide (PA), i-polyurethane (PU), i-PVC eguquguqukayo neqinile, kanye ne-PVC. I-Chimassorb 944 nayo isebenza kahle kakhulu ekusetshenzisweni okukhethekile kwama-elastomers nama-adhesive asekelwe ku-styrene.

Izici

✅I-Chimassorb 944 inokukhanya okuhle kakhulu futhi ingavimbela ngempumelelo ukuwohloka, ukushintsha kombala kanye nokuqhekeka kwamapulasitiki okubangelwa imisebe ye-ultraviolet.
✅I-UV Absorber 944 inezakhiwo ezinhle zokulwa nokukhishwa futhi ayithambekeli ekuthuthweni kusuka kumapulasitiki ngesikhathi sokusetshenziswa isikhathi eside.
✅I-UV 944 ihambisana kahle kakhulu futhi ingasakazwa ngokulinganayo emzimbeni wepulasitiki ngaphandle kokuthinta ukusebenza kokucubungula kanye nezakhiwo zomzimba nezemishini zepulasitiki.
