HDPE geomembrane ndi LDPE geomembrane

Geomembrane wakuda kwambiri ndi HDPE (high density polyethylene) geomembrane, pomwe geomembrane yoyera nthawi zambiri imakhala LDPE (low density polyethylene) geomembrane.Kusiyana pakati pa ziwirizi makamaka ndi kachulukidwe ndi ntchito.Kachulukidwe koyambirira ndi kokulirapo, pomwe kachulukidwe komaliza ndi kocheperako.Zakale zimagwiritsidwa ntchito kwambiri ngati zinthu za geotechnical, pomwe zomalizazi zimagwiritsidwa ntchito ngati filimu.

Chifukwa chomwe geomembrane yakuda ndi yakuda ndikuti geomembrane imapangidwa ndi black masterbatch, yomwe imaphatikizidwa mukupanga geomembrane molingana.Nthawi zambiri, masterbatch yaying'ono imatha kukonza ma geomembranes ambiri, ndipo tinthu tating'onoting'ono ta geomembrane masterbatch ndizovuta kukonza, zomwe sizingakhudze mtundu wa geomembrane.

White geomembrane ndi chifukwa white masterbatch particles amawonjezeredwa ku geomembrane, ndipo white masterbatch particles sichidzakhudza ubwino wa geomembrane.Kachulukidwe ndi magwiridwe antchito a geomembrane wakuda ndi apamwamba kuposa a white LDPE geomembrane chifukwa ambiri aiwo ndi HDPE geomembrane.Geomembrane yoyera ya LDPE imagwiritsidwa ntchito kwambiri ngati mapulasitiki apulasitiki, ndipo imagwiritsidwanso ntchito kwambiri.

Chifukwa kachulukidwe ka HDPE wakuda geomembrane ndi wamkulu kuposa LDPE woyera geomembrane, awiri adzakhala ndi ntchito zosiyana.Kuyerekeza kwamtundu wonse kuyeneranso kuzikidwa pakugwiritsa ntchito ziwirizo mumtundu womwewo wa zomangamanga.Kuyerekezerako kusakhale kozikidwa pa mphamvu zawo (zosayerekezeka).Awiriwa adzagwiritsidwa ntchito mosiyana pomanga mosiyanasiyana, ndipo nthawi zina amakhala m'malo mwa wina ndi mnzake.

Geomembrane yoyera ya LDPE ili ndi ductility yabwino kuposa yakuda HDPE geomembrane, ndipo kusinthasintha kwake kulinso kolimba kuposa HDPE geomembrane yakuda.Geomembrane yoyera ya LDPE yomwe imakwaniritsa zofunikira zomanga pulojekiti imakhalanso mbadwo watsopano wa zipangizo zomwe zingathe kutha, ndipo kusinthika kwake kudzakhalanso kolimba kuposa HDPE geomembrane yakuda mu pulojekiti yomweyo.Tsopano, ma projekiti ambiri amatha kuwonanso mthunzi wazinthuzo.

Zitha kuwoneka kuchokera pamwambapa kuti wakuda HDPE geomembrane ndi woyera LDPE geomembrane ali ndi ntchito zosiyanasiyana mu ntchito zosiyanasiyana, amene sangathe wamba.Mitundu iwiri ya mankhwala ili ndi mphamvu ndi zofooka zawo.Ubwino wa mitundu iwiri ya mankhwalawa uyenera kuganiziridwa potengera maudindo osiyanasiyana.
