UV 328 Ko te 290-400nm UV absorber ki pai te marama stabilization pānga-ma roto i te photochemistry; Ko te hua he kaha te whakauru o te rama ultraviolet, he iti te tae tuatahi i runga i te tae o te hua, he ngawari te whakarewa i roto i te plasticizer me te punaha monomer, he iti te ahua, he pai te hototahi ki te nuinga o nga rauemi turanga; i roto i nga hua o waho, ka taea te whakamahi me te phenolic antioxidant me te phosphate ester antioxidantand aukati i te amine photostabilizer.
Ka whakamahia te nuinga i roto i te polyolefin, PVC, HDPE, styrene kotahi me te copolymer, ABS, polymer kiriaku, polyester haunga, polythermoplastic polyamine, polyurethane rongoa maku, polyacetal, PVB (polyvinyl butyaldehyde), epoxy me te polyurethane e rua-waahanga punaha, waikawa waipiro me te kiriaku thermosetting. pūnaha peita autō; whakamahia ano hoki i roto i nga whakakikorua o nga motuka, i nga waahanga ahumahi, i nga taputapu rakau.
Taapirihia te nui: 1.0-3.0%, ka whakatauhia te moni taapiri motuhake kia rite ki te whakamatautau tono a nga kaihoko.
Kikī i roto i te 20Kg/25Kg peeke pepa kraft kaata ranei.
A ape i te ra, te marama nui, te makuku, me nga whakamaarama marama kei roto he whanariki, he huānga halogen ranei. Me penapena ki roto i te hiri, kia maroke, kia matara atu i te marama.
