Intshayelelo ye umbhobho we-epoxy Inkqubo yokwenza

1. Ukulungiswa kweglue. Fudumeza i-epoxy resin kwindawo yokuhlambela emanzini ukuya kwi-85 ~ 90 ℃, yongeza i-ejenti yokunyanga ngokwe-resin / i-ejenti yokunyanga (i-mass ratio) = 100/45, yivuse kwaye uyinyibilikise, kwaye uyigcine kwitanki yeglue phantsi kwemeko 80-85℃. .

2. I-fiber yeglasi inxeba kwi-metal round core mold, i-angle yokujikeleza i-longitudinal malunga ne-45 °, kunye nobubanzi bomsonto we-fiber yi-2.5mm. Umaleko wefiber yile: longitudinal winding 3.5mm thick + hoop winding 2 layers + longitudinal winding 3.5mm thick + 2 hoop windings.

3. Khupha ulwelo lweglue yeresin ukwenza umxholo weglu kumaleko wokujija ifayibha ubalwe njenge-26%.

4. Beka ityhubhu yeplastiki eshushu eshwabeneyo kubushushu obungaphandle, vuthela umoya oshushu ukuze ucuthe kwaye uwusonge ngokuqinileyo, emva koko usonge umaleko wangaphandle ngetape yelaphu yeglasi eyi-0.2mm ebanzi, i-20mm yelaphu leglasi ebanzi kwicala leringi, uze uyithumele i-oven yokunyanga ukunyanga.

1. Ukulawula ukunyanga, okokuqala ukunyuka ukusuka kwiqondo lokushisa ukuya kwi-95 ° C kwisantya se-3 ° C / 10min, yigcine i-3h, uze uyiphakamise kwi-160 ° C kwinqanaba elifanayo lokufudumeza, ligcine i-4h, uze uyikhuphe ngaphandle. i-oveni kwaye uyipholise ngokwendalo kwiqondo lobushushu begumbi.

6. Dlulisa, susa iteyiphu yelaphu yeglasi kumphezulu, kwaye wenze emva kokulungiswa njengoko kufuneka.
