He aha te Whakapumau Maama 292 CAS 41556-26-7?

Ko te Kaipupuri Maama 292 he whakapumau rama wai ka taea te whakaroa i te wa whakamaarama 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 Whakapumau Maama 292 he whakamaarama marama he ranunga o nga esters e rua, he awe tahi me te benzotriazole UV absorbers a ka taea te aukati i nga paninga kia pakaru me te tihorea o te mata i raro i te maaramatanga o te ra.

Taupānga

Ko te whakapumau marama 292 te nuinga e whakamahia ana 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 whakapumau marama 292 he pai ake mo nga miihini miihini me nga whakakikorua ahumahi. Te peita rakau, te whakamaroke marama i nga paninga ahumahi, te kapia PU, te whakapiri me etahi atu kirihou.

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