Ko te pāmahana o te amine uv absorber i roto i te tukanga whakarite e kore e teitei ake i te 110 ℃;he ngawari te whakatikatika tauhohenga;he ngawari te whakahaere i te tukanga tauhohenga;a he tiketike te parakore o te hua;Ko te punaha tauhohenga moata kaore e aro ki te wai, me tuku noa te wai i roto i te punaha ka tata te tauhohenga ki te whakaoti, ka ora ai te mahi.
Ko te hua me te tikanga whakarite o te maha-paanga thiether bisphenol acrylat antioxidant
TAU PATENGA: ZL201910569404.5
WHAKAARO
Phenol acrylate multi-pēnga antioxidant molecules kei roto e rua nga matua o nga roopu mahi antioxidant phenol i aukati, he awhina antioxidants here thioether me te waro hopu i nga rauropi kore mahi o te hangahanga haukawa phenolic kiriaku, e kawe mai ana i te syncretic pānga toru i roto i te hanga me te whakamahi i nga rauemi polymer.Ma tenei ka pai ake te tiaki i nga rauemi polymer, ka karo i nga hua o te whakaheke me te koroheketanga, te whakaoti i nga mahi ngoikore ka whakamahia te antioxidant mahi kotahi ki runga i nga taonga polymer.I tenei wa, he iti te paanga o te hohenga o te mahi whakarite me te whakapau kaha, a ka taea te tango i te filtration a-hua me te kore he wai para, me te whakarewa tukurua, na reira he pai te mahi.
He tikanga whakarite mo te pentaerythritol tino parakore hei awhina kirihou
