He aha te UV 292 CAS 82919-37-7?

Ko te UV 292 he whakapumau rama wai ka taea te whakaroa i te wa whakakitenga o waho o nga momo kirihou me nga paninga. I te wa o te tukatuka, kaore e puta he kakara ki nga polymers, ka pa ranei ki te tae taketake o te rauemi. Ehara i te mea ngawari i te wa e tukatuka ana i te pāmahana teitei, he pai ake te hototahi polymer.

Ko te UV 292 he whakapumau marama he ranunga o nga ester e rua, he awe tahi me te benzotriazole UV absorbers ka taea te aukati i nga paninga kia pakaru me te tihorenga o te mata i raro i te ra o te ra.

Taupānga

Ko te UV 292 te nuinga o te whakamahi i roto i nga polymers organic penei i te polyethylene, PVC, PVB, ABS resin, polyester, me te polyurethane. He pai rawa mo te polyurethane, i te mea he pai te whakarewatanga o te Light stabilizer 292 i roto i nga whakarewa.

Ko te UV 292 he pai ake mo nga whakakikorua motuka me nga taputapu ahumahi. Ko te peita rakau, te whakamaroke marama i nga paninga ahumahi, te kapia PU, te whakapiri me etahi atu kirihou.

Ko te UV 292 he pai te mahi tahi i te wa e whakamahia ana me nga momo benzotriazole UV absorbers, ka taea te whakapai ake i te parenga huarere o te hua, he pai ake i te whakamahi anake i nga UV absorbers. Ma te taapiri i nga dispersant e tika ana, ka taea e te Light stabilizer 292 te pai mo nga paninga wai.
