mankhwala

1.Kutonthoza ndi chitetezo:
bandeji imakhala ndi kuchepa pang'ono pambuyo poyanika, ndipo sichidzachititsa kuti khungu likhale lolimba komanso lopweteka pambuyo pouma bandeji. Komanso sizikuwoneka kuti gesso ili mu sclerosis, chifukwa kutulutsa kutentha pamene bibulous recrystallization, kumapangitsa khungu la odwala kukhala ndi vuto lomva kutentha.
2.Kukwanira kwa mpweya wabwino:
bandeji imagwiritsa ntchito ulusi wapamwamba kwambiri wokhala ndi mpweya wabwino, womwe umathetsa kusokonezeka kwa kutentha kwa kutentha ndi kuyabwa chifukwa cha mpweya woipa womwe umayamba chifukwa cha kuvala kwa chubu kwa nthawi yayitali, ndipo umapindulitsa pakhungu.
3.Light khalidwe ndi mkulu kuuma:
mphamvu yamphamvu ya bandeji yochiritsidwa ndi nthawi 20 kuposa bandeji ya pulasitala yachikhalidwe pambuyo poyesedwa, yomwe imagwira ntchito yodalirika pakukonzekera kuchepetsa kolondola. Pokhala ndi zinthu zochepa komanso kulemera kwake, bandeji ya polima imangokhala 1/5 ya kulemera kwake ndi 1/3 ya makulidwe a gypsum. Zimapangitsa kuti malo omwe akhudzidwawo akhale ochepa, ndipo amathandizira kufalikira kwa magazi, kulimbikitsa machiritso, kuchepetsa kulemetsa kwa zochita za anthu, sizingabweretse vuto loyenda.
4.Chiwonetsero chabwino kwambiri:
splint ndi bandeji ndi zabwino kwambiri cheza permeability ndi bwino X-ray zotsatira, amene angathe kuonetsetsa kuti adokotala akhoza molondola kumvetsa mmene mafupa Ankalumikiza ndi machiritso mafupa pamalo okhudzidwa. Palibe chifukwa chochotsera bandeji panthawi ya kafukufuku wa filimuyo, yomwe ndi yabwino kuti igwire bwino ntchito komanso imathandizira kuchepetsa ndi kumvetsetsa machiritso.
5.Kukana madzi abwino:
bandeji imakhala ndi kukana kwamadzi kwabwino, imatha kuteteza 85% ya kulowetsedwa kwamadzi akunja, mu gawo lomwe lakhudzidwa pambuyo polumikizana ndi chilengedwe chamadzi, imathanso kuonetsetsa kuti gawo lokhudzidwalo liwuma, losavuta kuyeretsa komanso kusamalira.
