Chii chinonzi Chimassorb 944 Cas 71878-19-8?

Chimassorb 944 (CAS 71878-19-8) imhando yepamusoro yekudzivirira mwenje inovharirwa ine mamorekuru akawanda (HALS).

UV Absorber 944 ipurasitiki ine mamorekuru akawanda anorema, ine simba shoma rekudzivirira kupararira kwemasero, uye simba rekudzivirira kupisa kwakanyanya. Mapoka emamine anodzivirirwa ari muchimiro chemakemikari cheUV 944 anogona kubata mafree radicals zvinobudirira, nokudaro achiita basa guru mukudzivirira kupararira kwechiedza.

Kushanda nesimba kwepolymeric kwakadzivisa kugadzikana kwechiedza cheamine, kushaya simba kwakanyanya, kufamba kwakaderera, kugadzikana kwekupisa uye mhedzisiro yekudzivirira oxidation, inoshanda pamwe chete nema antioxidants uye ma UV absorbers. UV Absorber 944 inogona kushandiswa kuma polyolefins, olefin copolymers, asiwo kune polyphenylene ether complexes, polyoxymethylene, amides, soft and hard PVC uye PVC blends.

Kushandiswa

Chimassorb 944 inogona kusimbisa kugadzikana kwechiedza chezvigadzirwa zvitete, kunyanya zvigadzirwa zvefiber nefirimu. UV 944 yakakodzerawo zvigadzirwa zve cross-section gobvu uye zvigadzirwa zve polyethylene.

Nzvimbo dzinoshandiswa neUV Absorber 944 dzinosanganisira mapurasitiki epolyolefin (akadai sePP, PE), olefin copolymers (akadai seEVA), uye musanganiswa wepolypropylene (PP) uye elastomers, nezvimwewo. Pamusoro pezvo, UV Absorber 944 inogona kushandiswawo mu polyoxymethylene (POM), polyamide (PA), polyurethane (PU), PVC inochinjika uye yakasimba, uye PVC. Chimassorb 944 inoshandawo zvikuru pakushandisa kwakakosha ma elastomers nema adhesives ane styrene.

Zvinhu zvirimo

✅Chimassorb 944 ine kugadzikana kwakanaka kwechiedza uye inogona kudzivirira kuora, kuchinja kweruvara uye kupwanyika kwemapurasitiki kunokonzerwa nemwaranzi ye ultraviolet.
✅UV Absorber 944 ine hunhu hwakanaka hwekudzivirira kubviswa kwechinhu uye haifambi kubva mumapurasitiki panguva yekushandiswa kwenguva refu.
✅UV 944 inoenderana zvakanaka uye inogona kupararira zvakaenzana mumuviri wepurasitiki pasina kukanganisa mashandiro ekugadzirisa uye hunhu hwemuviri uye hwemakanika epurasitiki.
