3250 Epoxy Glassfiber Laminated Sheet
Ingcaciso yeMveliso
Le mveliso yimveliso elaminethiweyo eyenziwe ngekhemikhali yonyango yombane enenjongo yombane ye-alkali-free yeglasi njengesixhobo sokuxhasa, ngokucinezela i-Tg ephezulu ye-epoxy resin njenge-binder.Inamandla aphezulu omatshini phantsi kobushushu obuphezulu, ngokuzinza kakuhle kombane phantsi komswakama ophezulu.
Iimbonakalo
1.Uzinzo oluhle lombane phantsi komswakama ophezulu;
2.Amandla aphezulu oomatshini phantsi kobushushu obuphezulu,
izinga lokugcinwa kwamandla koomatshini≥50% phantsi kwe-180℃;
3.Ukumelana nokufuma;
4.Ukumelana nobushushu;
5.Ukumelana nobushushu: iBanga H
Isalathiso sokuSebenza esiPhambili
Ngokuhambelana ne-GB / T 1303.4-2009 yombane we-thermosetting resin industrial hard laminates - Icandelo 4: i-epoxy resin hard laminates.
Ukubonakala: ubuso bufanele bube bucwecwe, bungabi namaqamza, imingxuma kunye nemibimbi, kodwa ezinye iziphene ezingachaphazeli ukusetyenziswa zivumelekile, ezifana nezi: imikrwelo, i-indentation, amabala kunye namabala ambalwa.
Isicelo
Ilungele zonke iintlobo zeemoto, izixhobo zombane, i-elektroniki kunye namanye amacandelo.
