Otu ọkụ UV si emetụta resin epoxy
Ihe ịtụnanya na-emerụ ihe ndị sịntetik gụnyere epoxy resin bụ radieshon UV. Photodegradation — ya bụ, ndakpọ nke kemịkalụ agbụ n'ime epoxy resin — nwere ike bute site na UV ìhè. Nrụrụ aka a nwere ike ibute:
1.Yellowing na Discoloration: UV ikpughe na-emekarị ka resin epoxy gbanwee odo na oge, nke na-adịghị mma, karịsịa mgbe doro anya dị mkpa, dị ka ihe eji achọ nkume ngwa ngwa.
2.Loss of Strength and Flexibility: Ogologo ogologo oge na UV nwere ike ime ka epoxy resin brittle, na-ebelata ike ya na ike nrapado, nke dị oké mkpa maka ijide nkume dị elu.
3.Surface Cracking: Ka oge na-aga, UV-mebiri epoxy resin nwere ike ịmalite ịgbawa n'elu, na-emebi njikọ dị n'etiti resin na nkume.
Nyere mmetụta ndị a, o doro anya ihe kpatara resin epoxy na-eguzogide UV ji dị mkpa maka ọrụ nkume n'èzí. N'agbanyeghị nke ahụ, ọ bụghị resin epoxy niile na-eguzogide ọgwụ UV, yabụ a na-achọkarị usoro ọzọ.
