Kodi ntchito za FR4 epoxy bolodi?

1. Various forms:

Ma resins osiyanasiyana, machiritso, ndi makina osinthira amatha kutengera zofunikira zamitundu yosiyanasiyana pamawonekedwe, ndipo mitunduyo imatha kukhala kuchokera ku viscosity yotsika kwambiri mpaka zolimba zosungunuka kwambiri.

2. Convenient curing:

Sankhani mitundu yosiyanasiyana yochiritsa, dongosolo la epoxy resin limatha kuchiritsidwa pafupifupi kutentha kwa 0 ~ 180 ℃.

3. Low shrinkage:

Zomwe zimachitika pakati pa utomoni wa epoxy ndi mankhwala ochiritsira omwe amagwiritsidwa ntchito amachitidwa ndi kuwonjezereka kwachindunji kapena kutsegula-kutsegula kwa polymerization kwamagulu a epoxy mu molekyulu ya utomoni, ndipo palibe madzi kapena zinthu zina zowonongeka zomwe zimatulutsidwa. Poyerekeza ndi unsaturated polyester resins ndi phenolic resins, amawonetsa kuchepa kwambiri (osakwana 2%) pakuchiritsa.

4. Strong adhesion:

Magulu a polar hydroxyl ndi zomangira za ether mu unyolo wa maselo a epoxy resins zimapangitsa kuti ikhale yomatira kuzinthu zosiyanasiyana. Kuchepa kwa utomoni wa epoxy kumakhala kochepa pochiritsa, ndipo kupsinjika kwamkati komwe kumapangidwa kumakhala kochepa, komwe kumathandizanso kukulitsa mphamvu zomata.

5. Mawotchi katundu:

Makina ochiritsidwa a epoxy resin ali ndi makina abwino kwambiri.
