HDPE = Umuvuduko mwinshi Polyethylene, cyangwa polyethylene yumuvuduko muke.Ubucucike buri hejuru ya 0.940.
LDPE = polyethylene yuzuye, cyangwa polyethylene yumuvuduko mwinshi, ni polyethylene polymerized munsi yumuvuduko mwinshi, hamwe nubucucike buri munsi ya 0.922.
Geomembrane yirabura ahanini ni HDPE (polyethylene yuzuye) geomembrane, naho geomembrane yera ahanini ni LDPE (polyethylene nkeya) geomembrane.Itandukaniro hagati yibi byombi ahanini mubucucike no mumikorere.Ubucucike bwambere ni bunini, mugihe ubucucike bwa nyuma ari buto.Iyambere ikoreshwa cyane nkibikoresho bya geotechnique, mugihe iyanyuma ikoreshwa nkibicuruzwa bya firime.
Impamvu ituma geomembrane yirabura iba umukara nuko geomembrane ikozwe hamwe na black masterbatch, yongewe mubikorwa byo kubyara geomembrane mukigereranyo.Mubisanzwe, umubare muto wa masterbatch urashobora gutunganya umubare munini wa geomembrane, kandi ibice bya geomembrane byoroshye byoroshye gutunganya, bitazagira ingaruka kumiterere ya geomembrane.
Geomembrane yera ni ukubera ibice byera byongewe kuri geomembrane, kandi ibice byera byera ntibizagira ingaruka kumiterere ya geomembrane.Ubucucike n'imikorere ya geomembrane yumukara birarenze ibya LDPE yera geomembrane kuko inyinshi muri zo ni HDPE geomembrane.Geomembrane yera ya LDPE ikoreshwa cyane nkibicuruzwa bya pulasitiki, kandi ikoreshwa cyane.
Kuberako ubucucike bwa HDPE umukara geomembrane buruta ubwa LDPE yera geomembrane, byombi bizakoreshwa bitandukanye.Kugereranya ubuziranenge muri rusange bigomba no gushingira kubikorwa byombi muburyo bumwe bwubwubatsi.Kugereranya ntibigomba gushingira ku mbaraga zabo (kutagereranywa).Byombi bizakoreshwa muburyo butandukanye mubwubatsi butandukanye, kandi rimwe na rimwe bizaba bisimburana.
Geomembrane yera ya LDPE ifite ihindagurika ryiza kuruta geomembrane yumukara HDPE, kandi ihinduka ryayo nayo irakomeye kuruta geomembrane yumukara HDPE.Geomembrane yera ya LDPE yujuje ibyangombwa byo kubaka umushinga nabwo ni igisekuru gishya cyibikoresho bya geoimpermeable, kandi guhuza n'imiterere nabyo bizakomera kuruta geomembrane yumukara HDPE mumushinga umwe.Noneho, imishinga myinshi irashobora kandi kubona igicucu cyibicuruzwa.
Birashobora kugaragara uhereye hejuru ko umukara HDPE geomembrane na geomembrane yera ya LDPE ifite porogaramu zitandukanye mumishinga itandukanye, idashobora kuba rusange.Ubwoko bubiri bwibicuruzwa bifite imbaraga nintege nke zabyo.Ubwiza bwubwoko bubiri bwibicuruzwa bugomba gutekerezwa hashingiwe kumyanya itandukanye.
