Gịnị bụ àgwà nke epoxy resin osisi?

Epoxy resin osisi na-akpọ mkpuchi mkpuchi, epoxy iko eriri osisi, 3240 epoxy iko eriri osisi. Epoxy resin na-ezo aka na ogige polymer organic nwere otu epoxy abụọ ma ọ bụ karịa n’ime molekul. The ikwu molekul uka nke bụ elu. Ihe e ji mara ihe owuwu molekul 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.

Various resins, curing agents, and modifier systems can almost adapt to the requirements of various applications on the form, and the range can be from extremely low viscosity to high melting point solids. Various curing agents are used for the curing side, and the epoxy resin system can almost be cured in the temperature range of 0~180℃.

1, ike nrapado

Ịdị adị nke polar hydroxyl na ether bond dị n’ime agbụ molekụla nke resin epoxy na-eme ka ọ nwee nnukwu nrapanye na ihe dị iche iche. Mbelata nke resin epoxy dị ala mgbe a na-agwọ ya, na nrụgide dị n’ime ahụ nke a na-emepụta dị ntakịrị, nke na-enyekwa aka mee ka ike nke ntanye dịkwuo mma.

2, strong contraction

“The reaction of the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage (less than 2%) during curing.

3, mechanical properties

Sistemụ resin epoxy a gwọrọ nwere ọmarịcha ihe eji arụ ọrụ.

4, eletriki arụmọrụ

Sistemu resin epoxy gwọrọ bụ ihe mkpuchi mkpuchi mara mma nke nwere akụrụngwa dielectric dị elu, nguzogide ntapu elu na nguzogide arc.

5, kemịkalụ kwụsie ike

N’ozuzu, usoro epoxy resin a gwọrọ nwere ezigbo nguzogide alkali, nguzogide acid na nguzogide ihe mgbaze. Dị ka ihe ndị ọzọ nke sistemu epoxy gwọrọ, nkwụsi ike kemịkalụ na-adaberekwa na resin ahọpụtara na onye na-agwọ ọrịa. Nhọrọ kwesịrị ekwesị nke resin epoxy na ihe na-agwọ ọrịa nwere ike ime ka ọ nwee nkwụsi ike kemịkalụ pụrụ iche.

6, nkwụsi ike akụkụ

The combination of many of the above properties makes the epoxy resin system have outstanding dimensional stability and durability.

7, ebu na-eguzogide

Usoro resin epoxy gwọrọ na-eguzogide ọtụtụ ebu ma enwere ike iji ya n’okpuru ọnọdụ okpomọkụ siri ike.
