Malinga ndi njira zosiyanasiyana, zitha kugawidwa m'magulu awiri: pepala lolimba losefera ndi pepala losefera lomwe silinachiritsidwe.Mapepala a fyuluta ochiritsidwa nthawi zambiri amaikidwa ndi phenolic resin, kenako amawotcha pa kutentha kwa 150-180 madigiri pafupifupi 15 mphindi kuti athetse utomoni ndikuwonjezera kukhwima kwa pepala losefera.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, silimatenthedwa, silimatenthedwa kwambiri, ndi losamva alkali.
Pawelson® air fyuluta 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.
