Chifukwa pepala la fyuluta liyenera kukhala lopanikizika kwa nthawi yaitali pa ntchito, m'pofunika kupeza njira yowonjezera mphamvu ya pepala la fyuluta, mwinamwake idzawola mosavuta. Chifukwa chake, pepala losefera la mafakitale liyenera kukonzedwa ndi "kuviika"!

Malinga ndi njira zosiyanasiyana, zitha kugawidwa m'magulu awiri: pepala lolimba losefera ndi pepala losefera lomwe silinachiritsidwe. Mapepala a fyuluta ochiritsidwa nthawi zambiri amapangidwa ndi phenolic resin, kenako amawotcha pa kutentha kwa madigiri 150-180 kwa mphindi pafupifupi 15 kuti athetse utomoni ndikuwonjezera kukhwima kwa pepala la fyuluta. Apa "pepala losefera lochiritsa" linatuluka!
"Pepala lopangidwa ndi fyuluta" limathandizidwa ndi kutentha kwambiri, ndipo ulusi wamapepalawo umakhala wokutidwa ndi utomoni. "Pepala losefera lomwe silinachiritsidwe" nthawi zambiri limagwiritsa ntchito utomoni wa polyvinyl acetate ngati woyimiritsa, ndipo limamalizidwa ndikudontha mwachilengedwe pambuyo pa kutenga pakati. Choncho, kuuma ndi kuuma kwa pepala la fyuluta sikuli bwino ngati "pepala la fyuluta yowonongeka". Komanso, "pepala losefa lomwe silinachiritsidwe" ndilosavuta kuyamwa madzi ndikukhala lonyowa, ndipo panthawi imodzimodziyo, kukana kwake kutentha kwakukulu sikuli bwino ngati "pepala la fyuluta lochiritsidwa". Zida zamitundu iwiriyi ya pepala losefera ndizofanana, koma njira yotsatsira yomwe imatsatira ndiyosiyana kwambiri! ——”Pepala losefa lochiritsidwa” mwachiwonekere ndilobwinoko, losaloŵerera madzi, losamva asidi, losatentha kwambiri, silimatenthedwa bwino, ndi losamva alkali.
Pawelson® fyuluta ya mpweya imagwiritsa ntchito pepala losefera la Ahlstrom, ndipo pepala losefera lachiritsidwa kutentha kwambiri, ziribe kanthu kuti injini yanu ikukumana ndi madera ovuta, nthawi zonse imaonetsetsa kuti injini yanu ikugwira ntchito kwambiri.
