Glacadair UV
Fo sholas na grèine agus fluorescence, bidh plastaigean agus stuthan polymer eile a ’faighinn ath-bhualadh oxidation fèin-ghluasadach fo ghnìomhachd ghathan ultraviolet, a tha a’ leantainn gu truailleadh polymers agus crìonadh ann an coltas agus feartan meacanaigeach. Às deidh an sùgh ultraviolet a chuir ris, faodar na ghathan ultraviolet àrd-lùth a ghabhail a-steach gu roghnach agus a thionndadh gu lùth gun chron airson a leigeil ma sgaoil no a chaitheamh. Air sgàth nan diofar sheòrsaichean polymers, tha na tonnan ultraviolet a tha gan lughdachadh cuideachd eadar-dhealaichte. Faodaidh diofar shùlairean ultraviolet ghathan ultraviolet a ghabhail a-steach le tonnan eadar-dhealaichte. Nuair a bhios tu a’ cleachdadh, bu chòir na absorbers ultraviolet a thaghadh a rèir an seòrsa polymers.
Faodar absorbers UV a roinn anns na seòrsaichean a leanas a rèir an structar ceimigeach aca: salicylates, benzones, benzotriazoles, acrylonitrile ionaid, triazine agus feadhainn eile.
