Ngā Tohu Hua

He aha te Chimassorb 944 Cas 71878-19-8?

Ko te Chimassorb 944 (CAS 71878-19-8) he mea whakaū mārama amine taumaha-ngota teitei (HALS).

Ko te UV Absorber 944 he mea whakapūmau mārama amine taumaha-ngota teitei kua whakakotahitia, he iti te piki me te heke, he ātete ki te pāmahana teitei. Ka taea e ngā rōpū amine kua āraihia i roto i te hanganga matū o te UV 944 te hopu pai i ngā rauropi kore utu, ā, ka whai wāhi nui ki te whakapūmau mārama.

He pai te mahi a te polymeric ki te whakaū i te mārama amine, he iti te mimiti, he iti te hekenga, he pumau te wera me te ārai i te waikura, he mahi tahi me ngā antioxidants me ngā ngongo UV. Ka taea te whakamahi i te UV Absorber 944 ki ngā polyolefins, ngā copolymers olefin, engari mō ngā matatini polyphenylene ether, te polyoxymethylene, ngā amides, ngā ranunga PVC ngohengohe me te mārō me te PVC.

Tono

Ka taea e te Chimassorb 944 te whakarei ake i te pumau o te māramatanga o ngā hua angiangi, inā koa ngā hua muka me te kiriata. He pai hoki te UV 944 mō ngā hua tapahi matotoru me ngā hua polyethylene.

Ko ngā mara tono o te UV Absorber 944 ko ngā kirihou polyolefin (pēnei i te PP, PE), ngā copolymers olefin (pēnei i te EVA), me ngā ranunga o te polypropylene (PP) me ngā elastomers, me ētahi atu. Hei tāpiri, ka taea hoki te whakamahi i te UV Absorber 944 i roto i te polyoxymethylene (POM), te polyamide (PA), te polyurethane (PU), te PVC ngāwari me te pakari, me ngā ranunga PVC. He tino whai hua hoki te Chimassorb 944 mō ngā tono motuhake o ngā elastomers me ngā piripiri e hangai ana ki te styrene.

Ngā Āhuatanga

✅He tino pai te pumau o te Chimassorb 944 ki te mārama, ā, ka taea e ia te ārai i te pirau, te tae ke me te pakarukaru o ngā kirihou i puta mai i ngā hihi ultraviolet.
✅He pai ngā āhuatanga ātete-tango o te UV Absorber 944, ā, kāore e ngāwari ki te neke atu i ngā kirihou i te wā e whakamahia ana mō te wā roa.
✅He tino hototahi te UV 944, ā, ka taea te horapa ōrite i roto i te tinana kirihou, me te kore e pā ki te mahi tukatuka me ngā āhuatanga ā-tinana me ā-pūkaha o te kirihou.
