Pepalandi gawo limodzi la zosefera zapadera zosefera. Ngati zagawidwanso, zili ndi: pepala la mafuta osefera, pepala losefeseka, mapepala osefa kwambiri, ndi otero. Musaganize kuti chidutswa chaching'ono chikuwoneka kuti sichingakhale ndi zotsatira. M'malo mwake, zotsatira za zosefera zitha kupanga nthawi zina sizikhala ndi zinthu zina.
Kuchokera papepala, imapangidwa ndi ulusi wolumikizana. Ma fiber amasunthika wina ndi mnzake kuti apange mabowo ang'onoang'ono ambiri, kotero kuvomerezedwa ndi mpweya kapena madzi ndibwino. Kuphatikiza apo, makulidwe a pepalalo amatha kukhala akulu kapena ochepa, mawonekedwewo ndi osavuta kutengera, ndipo kutsikira ndi kudula ndikosavuta kwambiri. Nthawi yomweyo, malinga ndi mtengo wopangira, mayendedwe ndi kusungirako, mtengo wake ndi wocheperako.
Mwachidule,pepala la floseItha kugwiritsidwa ntchito polekanitsa, kuyeretsa, kusanthula, kufooketsa, ndi zina zambiri.
Zina mwa zinthu zophika zomwe zimagwiritsidwa ntchito mu pepala zosefera ndizomwe zimamera, monga mapepala osefera mankhwala; Ena ndi ulusi wagalasi, ulusi wopangidwa, aluminium slika fbers; Ena amagwiritsa ntchito ulusi wazomera ndikuwonjezera ulusi wina, ngakhale kuphatikiza zitsulo. Kuphatikiza pa ulusi wosakanizika womwe uli pamwambapo, mafilimu ena, monga perlite, oyambitsidwa ndi nthaka, onyowa mphamvu zolimba, enc., iyenera kuwonjezeredwa malinga ndi formula. Pambuyo pamachitidwe angapo, pepala lomalizidwa kuchokera pamakina a pepala limakonzedwanso monga momwe likufunira: Itha kupopera mbewutsedwe, kuphatikizidwa, kapena zokhala ndi zinthu zina.
Kuphatikiza apo, pansi pa zinthu zapadera, pepala losefera limafunikiranso kukana kutentha kwambiri, kukana moto ndi kukana madzi, komanso adsorption ndi mishoni. Mwachitsanzo, kuphatikizira kwa mpweya wa ma railesi ndi kuphatikizika kwa mafuta oyengedwa, etc.
