The nembanemba yokutidwa fumbi kuchotsa madzi fyuluta thumba wapangidwa polytetrafluoroethylene microporous nembanemba ndi zipangizo zosiyanasiyana m'munsi (PPS, galasi CHIKWANGWANI, P84, aramid) ndi luso lapadera gulu. Cholinga chake ndi kupanga kusefera pamwamba, kotero kuti mpweya wokhawo umadutsa muzosefera, ndikusiya fumbi lomwe lili mu gasi pamtunda wa zinthu zosefera.
Kafukufukuyu akuwonetsa kuti chifukwa filimu ndi fumbi pamwamba pa zosefera zimayikidwa pamwamba pa zosefera, sizingalowe muzosefera, ndiko kuti, pore pore ya nembanembayo imasokoneza zinthu zosefera, ndipo palibe mkombero woyamba kusefa. Chifukwa chake, thumba lazosefera la fumbi lokutidwa lili ndi ubwino wokwanira mpweya waukulu, kukana kutsika, kusefa bwino, mphamvu yafumbi yayikulu, komanso kutulutsa fumbi lalikulu. Poyerekeza ndi zosefera zachikhalidwe, kusefera ndikopambana.
Masiku ano mafakitale, kusefera kwamadzi kumagwiritsidwa ntchito kwambiri popanga. The ntchito mfundo ya madzi thumba kusefera ndi chatsekedwa kuthamanga kusefera. Dongosolo lonse losefera thumba limaphatikizapo magawo atatu: chidebe chosefera, dengu lothandizira ndi thumba lasefa. Madzi osefedwa amalowetsedwa mu chidebe kuchokera pamwamba, amayenda kuchokera mkati mwa thumba kupita kunja kwa thumba, ndipo amagawidwa mofanana pamtunda wonse wosefera. Tizigawo tosefedwa timatsekeredwa m'thumba, lotayirira laulere, losavuta kugwiritsa ntchito komanso losavuta kupanga, mawonekedwe ake onse ndi abwino, ntchito yake ndi yabwino, mphamvu yogwirira ndi yayikulu, ndipo moyo wautumiki ndi wautali. Ndi kutsogolera zopulumutsa mphamvu mankhwala mu madzi kusefa makampani, ndipo ndi oyenera kusefera coarse, wapakatikati kusefera, ndi kusefera zabwino zilizonse particles kapena zolimba inaimitsidwa.
Chonde funsani dipatimenti yathu yogulitsa kuti mudziwe zambiri zamatumba amadzimadzi. Zopanda zokhazikika zimathanso kuyitanidwa mwapadera.
