A na-eji epoxy UV curing resin n'ọtụtụ ebe n'ọhịa nke nkedo mkpuchi eletriki, mkpuchi mgbochi corrosion, njikọta ígwè na ihe ndị ọzọ n'ihi ike njikọta ya dị elu, elu njikọ obosara, obere shrinkage, nkwụsi ike dị mma, mkpuchi ọkụ eletrik mara mma, ike igwe dị elu na ezi usoro ikike.N'afọ ndị na-adịbeghị anya, epoxy UV na-agwọ resin dị ka ụlọ ọrụ na-eto eto.
Otú ọ dị, ugbu a, ihu igwe na-eguzogide ọtụtụ ngwaahịa epoxy adịghị ike, karịsịa na mmepụta nke epoxy adhesive, led potting adhesive, epoxy UV curing resin ọla nrapado, wdg, ngwaahịa chọrọ agba siri ike, nke na-ebutekwa elu elu. chọrọ maka mgbochi yellowing arụmọrụ nke epoxy usoro.
Enwere ọtụtụ ihe na-eme ka ngwaahịa epoxy na-acha odo odo: 1. The bisphenol a Ọdịdị nke aromatic epoxy UV curing resin dị mfe oxidize na-emepụta carbonyl na-etolite yellowing otu;2. The free amine akụrụngwa na amine na-agwọ ọrịa bụ kpọmkwem polymerized na epoxy UV curing resin, na-akpata na mpaghara okpomọkụ ịrị elu na accelerated yellowing;3. Tertiary amine accelerators na nonylphenol accelerators dị mfe ịgbanwe agba n'okpuru ikuku oxygen na UV irradiation;4. Ọ bụrụ na okpomọkụ dị oke elu n'oge mmeghachi omume ahụ, ihe ndị fọdụrụ na-adịghị ọcha na ihe ndị na-eme ka ígwè dị na usoro ahụ ga-eme ka a na-acha odo odo.
Ngwọta dị irè bụ ịgbakwunye antioxidant na ultraviolet absorber, nke nwere ike igbochi nke ọma ma gbuo oge ịcha edo edo.Agbanyeghị, enwere ọtụtụ ụdị antioxidants, na ịhọrọ ngwaahịa dabara adaba chọrọ nkwado teknụzụ na mkpokọta ahụmịhe.
Nkewa nke antioxidants: otu bụ isi antioxidant: weghara peroxide free radicals, tumadi na-egbochi phenol antioxidants;Otu bụ antioxidant inyeaka: decompose hydroperoxides, tumadi phosphite esters na thioesters.N'ozuzu, a na-atụ aro antioxidants dị iche iche dị ka usoro mmepụta ihe, ihe ndị na-emepụta ihe, ihe mgbaze, ihe mgbakwunye na ndị na-emepụta ihe dị iche iche, nke ọkwa nke yellowing na ogo nke yellowing.
Ìhè ultraviolet bụkwa ihe dị mkpa na-akpata oxidation yellowing nke usoro epoxy, tumadi site na ìhè anyanwụ.Ya mere, karịsịa maka ndị ahịa nke ngwaahịa ha kwesịrị iji n'èzí, anyị ga-akwado ịgbakwunye ụfọdụ ihe ntinye UV na ngwaahịa, nke nwere ike ịmịkọrọ UV nke ọma ma gbuo oge na-acha odo odo.Ọzọkwa, iji ultraviolet na antioxidant nwere ike ime mmetụta synergistic, yana mmetụta na 1 gbakwunyere 1 karịrị 2.
N'ezie, ojiji nke antioxidants na ultraviolet absorbers enweghị ike fundamentally dozie nsogbu nke yellowing, ma n'ime a ụfọdụ nso na oge, ọ nwere ike n'ụzọ dị irè gbochie ọxịdashọn yellowing nke ngwaahịa, na-na mmiri na agba nke ngwaahịa transperent ma melite ọkwa nke ngwaahịa. .
