Dalili na ɗaya don manna azurfa:

Formula ta 1:

Conductive azurfa manna tunani dabara 2: conductive azurfa foda, E-44 epoxy guduro, tetrahydrofuran, polyethylene glycol

Azurfa foda: 70% -80%

Epoxy guduro: tetrahydrofuran shine 1: (2-3)

Epoxy resin: wakili na warkewa shine 1.0: (0.2 ~ 0.3)

Epoxy guduro: polyethylene glycol shine 1.00: (0.05-0.10)

Babban ma'anar tafasa: butyl anhydride acetate, diethylene glycol butyl ether acetate, diethylene glycol ethyl ether acetate, isophorone.

Babban aikace-aikace na low kuma na al'ada zafin jiki curing conductive azurfa manne: yana da halaye na low curing zafin jiki, high bonding ƙarfi, barga lantarki yi, da kuma dace da allo bugu, lantarki da kuma thermal watsin bonding a al'ada zafin jiki curing waldi lokatai, kamar su. ma'adini lu'ulu'u, infrared pyroelectric inji, piezoelectric yumbu, potentiometers, flash shambura da garkuwa, kewaye gyare-gyare, da dai sauransu
