Waa maxay shaqooyinka FR4 looxa epoxy?

1. Various forms:

Resins kala duwan, wakiilada daweynta, iyo hababka wax ka beddelka waxay ku dhawaad ​​​​la qabsan karaan shuruudaha codsiyada kala duwan ee foomka, iyo kala duwanaanshadu waxay noqon kartaa mid aad u hooseeya ilaa heerkul sare oo adag.

2. Convenient curing:

Dooro noocyo kala duwan oo dawooyin ah oo kala duwan, nidaamka resin epoxy ku dhawaad ​​waxaa lagu daweyn karaa inta u dhaxaysa heerkulka 0 ~ 180 ℃.

3. Low shrinkage:

Dareen-celinta u dhaxaysa xabagta epoxy-ga iyo wakiilka daawaynta ee la isticmaalo waxa lagu fuliyaa fal-celin toos ah oo dheeraad ah ama falcelinta polymerization-ka-furay ee kooxaha epoxy-ga ee molecule-ka xabagta, oo aan biyo ama alaab kale oo kacsani soo baxayn. Marka la barbar dhigo resins polyester-ka aan dheregsanayn iyo xabagta phenolic, waxay muujinayaan hoos u dhac aad u hooseeya (in ka yar 2%) inta lagu jiro daawaynta.

4. Strong adhesion:

Kooxaha dabiiciga ah ee hydroxyl polar iyo curaarta ether ee silsiladda molecular ee resins epoxy waxay ka dhigaan mid aad ugu dheggan walxo kala duwan. Hoosudhaca resin epoxy waa hooseeyaa marka la daweynayo, iyo walbahaarka gudaha ka dhasha waa mid yar, kaas oo sidoo kale gacan ka geysta hagaajinta xoogga adhesion.

5. Mechanical properties:

Nidaamka resin epoxy ee la daweeyay wuxuu leeyahay sifooyin farsamo oo aad u wanaagsan.
