3250 Epoxy Glassfiber Laminated Sheet
Incazelo Yomkhiqizo
Lo mkhiqizo ungumkhiqizo owenziwe nge-laminated owenziwe ngendwangu yengilazi yengilazi engena-alkali enenhloso kagesi ehlosiwe njengezinto ezisekelayo, ngokucindezela ngokushisa nge-Tg epoxy resin ephezulu njenge-binder.Unamandla amakhulu okusebenza ngaphansi kwezinga lokushisa eliphezulu, nokusimama okuhle kagesi ngaphansi komswakama ophezulu.
Izici
1.Ukuzinza okuhle kukagesi ngaphansi komswakama ophezulu;
2.Amandla aphezulu emishini ngaphansi kwezinga lokushisa eliphezulu,
izinga lokugcinwa kwamandla emishini≥50% ngaphansi kuka-180℃;
3.Ukumelana nomswakama;
4.Ukumelana nokushisa;
5.Ukumelana nezinga lokushisa: Ibanga H
Inkomba Yokusebenza Eyinhloko
Ngokuhambisana ne-GB/T 1303.4-2009 kagesi we-thermosetting resin industrial hard laminates - Ingxenye 4: i-epoxy resin hard laminates.
Ukubukeka: indawo engaphezulu kufanele ibe isicaba, ingabi namabhamuza, imigodi kanye nemibimbi, kodwa ezinye iziphambeko ezingaphazamisi ukusetshenziswa zivunyelwe, njengokuthi: imihuzuko, indentation, amabala kanye namabala ambalwa.Unqenqema kufanele lunqunywe kahle, futhi ubuso bokugcina abuyikuchithwa futhi buqhekeke.
Isicelo
Ifanele zonke izinhlobo zezimoto, izinto zikagesi, zikagesi nezinye izinkambu.
