Kukula kwa geomembrane

Kuyambira m'ma 1950, mainjiniya apanga bwino ndi geomembranes.Kugwiritsa ntchito ma geomembranes, omwe amatchedwanso flexible membrane liners (FMLs), kwawonjezeka chifukwa cha nkhawa yomwe ikukulirakulira pakuipitsidwa kwa madzi ofunikira.Traditional porous liners, monga konkire, admix zipangizo, dongo ndi dothi zatsimikizirika zokayikitsa popewa kusamuka madzimadzi kupita subsurface dothi ndi pansi.Mosiyana ndi izi, kulowera mumitundu yosagwirizana ndi ma liner, omwe ndi geomembranes, kwakhala mwadzina.Ndipotu, poyesedwa mofanana ndi dongo, kutsekemera kwamadzimadzi kudzera mu geomembrane yopangidwira kwakhala kosawerengeka.Zofunikira pakukhazikitsa zimatsimikizira mtundu wa geomembrane.Ma geomembranes amapezeka mumitundu yosiyanasiyana yakuthupi, yamakina komanso kukana mankhwala opangidwa kuti akwaniritse zofunikira zamitundu yosiyanasiyana.Zogulitsazo zitha kuphatikizidwa kuti ziwonetsedwe ndi kuwala kwa ultraviolet, ozoni ndi tizilombo tating'onoting'ono m'nthaka.Kuphatikizika kosiyanasiyana kwazinthu izi kumapezeka muzipangizo zosiyanasiyana za geosynthetic kuti zikwaniritse mitundu ingapo ya ntchito ndi mapangidwe a geotechnical.Njira zingapo zimagwiritsidwa ntchito kulumikiza zida za geosynthetic mu fakitale komanso m'munda.Chilichonse chili ndi njira zowongolera bwino zomwe zimayendetsa kupanga ndi kuyika kwake.Zogulitsa zatsopano komanso njira zopangira ndi kukhazikitsa zikupitilizabe kupangidwa pomwe makampaniwo akuwongolera ukadaulo wake.Daelim, yemwe amadziwika kuti ndi mtsogoleri pakati pamakampani opanga mafuta a petrochemical ku Korea okhala ndi ma naptha crackers ndi zomera zofananira za utomoni wakumunsi, ali ndi mphamvu yapachaka yokwana matani 7,200 a HDPE Geomembrane okhala ndi makulidwe oyambira 1 mpaka 2.5 mm ndi m'lifupi mwake mpaka 6.5 m.Daelim Geomembranes amapangidwa ndi lathyathyathya-kufa extrusion njira pansi ulamuliro okhwima khalidwe.Ogwira ntchito zaluso zamkati ndi malo a R&D apatsa Daelim luso lapadera lopatsa makasitomala mitundu yosiyanasiyana yaukadaulo yomwe ili yofunikira pakupanga mawu ndikuyika ma geomembranes.
