FR4 osisi epoxy osisi

FR4 osisi epoxy osisi a na-marakwa dị ka epoxy iko eriri osisi, epoxy phenolic laminated iko akwa osisi, nlereanya 3240, epoxy resin n’ozuzu na-ezo aka ihe organic polymer compound nwere abụọ ma ọ bụ karịa epoxy iche iche na molekul, ma e wezụga ole na ole, ha ikwu molekul uka adịghị elu. . Ọdịdị molekụla nke resin epoxy bụ ọnụnọ nke otu epoxy na-arụ ọrụ na yinye molekụla, na otu epoxy nwere ike ịnọ na njedebe, n’etiti ma ọ bụ cyclic nke agbụ molekul. N’ihi otu epoxy na-arụsi ọrụ ike na usoro ihe omimi, enwere ike ijikọ ha na ụdị ọgwụgwọ dị iche iche iji mepụta polymers na-adịghị ike na enweghị ike nwere usoro netwọkụ ụzọ atọ.

Atụmatụ Ngwa:

1. Ụdị dị iche iche. Ụdị resin dị iche iche, ndị na-agwọ ọrịa, na sistemu mgbanwe dị ka dabara na ụdị ngwa ọ bụla chọrọ, sitere na viscosities dị ala ruo na ebe mgbaze dị elu.

2. Ọ dị mfe ịgwọ ọrịa. N’iji ihe dị iche iche na-agwọ ọrịa, usoro epoxy resin nwere ike gwọọ ya na okpomọkụ nke 0 ruo 180 Celsius.

3. Ike adhesion. Ịdị adị nke polar hydroxyl na ether bond dị n’ime agbụ molekụla nke epoxy resin na-eme ka ọ nwee nnukwu nrapanye na ihe dị iche iche. Epoxy resins nwere obere mbelata mgbe a gwọrọ ya ma na-ebute ntakịrị nchekasị dị n’ime, nke na-enyekwa aka n’ịkwalite ike nrapado.

4. Obere shrinkage. A na-eme mmeghachi omume nke resin epoxy na onye na-agwọ ọrịa ahụ site na mmeghachi omume mgbakwunye ozugbo ma ọ bụ polymerization nke mmeghe nke otu epoxy dị na resin molecule, na-enweghị ntọhapụ nke mmiri ma ọ bụ ngwaahịa ndị ọzọ na-agbanwe agbanwe. Ha na-egosi mbelata nke ukwuu (ihe na-erughị 2%) n’oge ọgwụgwọ ma e jiri ya tụnyere resin polyester na-enweghị saturated na resin phenolic.

1. Njirimara igwe. Usoro mmanụ resin epoxy gwọrọ nwere ezigbo ihe eji arụ ọrụ.
