A. okuphansi voltage ukwahlukanisa impahla
1.1 Ifomula
I-Epoxy resin E-44 100
I-Diluent Dibromophenyl glycidyl ether 20
Flame cishe yizona ezisetshenziswa kabanzi antimony trioxide 10
I-silica powder esebenzayo i-400 mesh 200
Umenzeli welapha 593 25
I-Diethylenetriamine 3
1.2 Inqubo Yokukhiqiza
1.2.1 I-silicon powder eyomile kokuqukethwe komswakama ngaphansi kwe-0.2%
1.2.2 Faka i-epoxy resin, thinner, flame retardant, ne-silicon powder ku-reactor ngendlela elandelayo
1.2.3 Khuphula izinga lokushisa liye ku-100 ℃, ligaye ingxube ingaphansi kwe -0.1Mpa ye-30min ifane
1.2.4 Epholile iye ngaphansi kuka-50 ° C, engeza i-ejenti ephulukisayo, gcina izinga lokushisa lingadluli ku-50 ° C, i-degas vacuum degree -0.1Mpa, isikhathi sokuxuba esingekho ngaphezu kwe-30min, bese ufaka inqubo yokusakaza.
B. Izinto eziphakeme zokufaka amandla kagesi namandla aphansi
2.1 Ukwakheka
I-Epoxy resin E-44 100
I-Diluent Dibromophenyl glycidyl ether 20
Flame cishe yizona ezisetshenziswa kabanzi antimony trioxide 10
I-silica powder esebenzayo i-400 mesh 300
Umenzeli welapha i-S101 95
I-Accelerator DMP-30 1.5
Inqubo yokukhiqiza 2.2
2.2.1 I-silicon powder eyomile kokuqukethwe komswakama ngaphansi kuka-0.2%
2.2.2 Yenza izingxenye ezimbili ngokulandelana okulandelayo
Ingxenye ye-epoxy resin, i-accelerator, i-flame retardant, i-silicon powder 200
Umenzeli ophulukisa ingxenye ye-B, ozacile, i-silicon powder 100
2.2.3 Ingxenye ye-A ishubile ifike ku-80-100 ℃, bese ingxube ifakwa ngaphansi kwe -0.1Mpa vacuum ye-30min ifane
2.2.4 Izinga lokushisa kwengxenye B lenyuswa laya ku-50 ℃, kanti ingxube isuswa ngaphansi kwe -0.1Mpa vacuum ye-30min ifane
2.2.5 Epholile iye ngaphansi kuka-50 ℃, engeza ingxenye A engxenyeni B, gcina izinga lokushisa lingabi ngaphezu kwama-50 ℃, iziqu ze-degas vacuum -0.1Mpa, isikhathi sokuxuba 30min, ungangena uthela.
