Gịnị bụ ojiji ọnọdụ nke epoxy iko eriri osisi

Epoxy iko eriri osisi bụkwa epoxy phenolic laminated iko akwa osisi. Epoxy resin na-ezokarị aka na ogige polymer organic nwere otu epoxy abụọ ma ọ bụ karịa n’ime molekul. Ewezuga ole na ole, ọnụọgụ molekụla ha dị iche iche. elu. Ihe e ji mara ihe owuwu molekụla nke resin epoxy bụ otu epoxy na-arụ ọrụ na yinye molekụla. Otu epoxy nwere ike ịdị na njedebe, n’etiti ma ọ bụ na usoro cyclic nke yinye molekụla. N’ihi na ihe owuwu molekụla ahụ nwere otu epoxy nọ n’ọrụ, ha nwere ike nweta mmeghachi omume na-ejikọta ya na ụdị ọgwụgwọ dị iche iche iji mepụta polymers na-adịghị ike na enweghị ike nwere usoro netwọkụ ụzọ atọ.
