A. Maualalo volitiga mea faʻaʻesega
1.1 Faʻavae
Epoxy resin E-44 100
Diluent Dibromophenyl glycidyl ether 20
Trioxide faʻasolosolo mumusu i le afi 10
Efuefu silica mataalia 400 mesh 200
Faʻaleleia vailaʻau 593 25
Diethylenetriamine 3
1.2 Gaosiga gaioiga
1.2.1 mago silicon efuefu i le susu mataupu i lalo 0.2%
1.2.2 Faʻaopopo le epoxy resin, manifinifi, faʻamamaina le afi, ma le silicon efuefu i le reactor i le faʻatonuga lenei
1.2.3 Siitia le vevela i le 100 ℃, degas le paluga i lalo -0.1Mpa lagona gaogao mo 30min i le laugatasia
1.2.4 Malulu i lalo ole 50 ° C, faʻaopopo vailaʻau sooupu, tausia le vevela e le sili atu i le 50 ° C, degas lagona gaogao tikeri -0.1Mpa, faʻafefiloi taimi e le sili atu i le 30min, ona ulufale lea i le lafoina gaioiga.
B. Maualuga voltage ma maualalo voltage voltage mea faʻaaogaina
2.1 Fausiaina

2.2 Faʻagasologa o gaioiga
2.2.1 mago silicon efuefu i le susu mataupu i lalo 0.2%
2.2.2 Fai se lua-vaega i le faʻasologa lenei
O le elemeni epoxy resin, accelerator, flame retardant, silicon efuefu 200
B vaega faʻamalolo sooupu, manifinifi, silicon efuefu 100
2.2.3 O le A vaega e vevela i le 80-100 ℃, ma o le faʻafefiloi e degassed lalo -0.1Mpa lagona gaogao mo 30min i le laugatasia
2.2.4 O le vevela o le vaega B ua siitia i le 50 ℃, ma o le paluga ua degassed lalo -0.1Mpa lagona gaogao mo 30min i le laugatasia
2.2.5 Cool i lalo 50 ℃, faaopoopo vaega A i le vaega B, tausia le vevela e le sili atu i le 50 ℃, degas lagona gaogao tikeri -0.1Mpa, palu taimi 30min, oe mafai ona ulu atu sasaʻa.
