I-Geomembrane yimathiriyeli ye-geomembrane eyenziwe ngefilimu yeplastiki njenge-substrate engenamandla kunye nelaphu elingalukwanga.Ukusebenza okungenakuthintelwa kwezinto ezintsha ze-geomembrane ikakhulu kuxhomekeke kwintsebenzo engabonakaliyo yefilimu yeplastiki.Iifilimu zeplastiki ezisetyenziselwa ukukhusela i-seepage ekhaya nakwamanye amazwe zibandakanya i-polyvinyl chloride (PVC), i-polyethylene (PE), kunye ne-EVA (i-ethylene / vinyl acetate copolymer).Kwizicelo zetonela, kukwakho noyilo olusebenzisa i-ECB (i-ethylene acetate i-asphalt blend geomembrane).Zizinto eziguquguqukayo zeekhemikhali ze-polymer ezinomxhuzulane okhethekileyo, ukolula olomeleleyo, ukuxhathisa okuphezulu kwe-deformation, ukumelana nokugqwala, ukumelana nobushushu obuphantsi, kunye nokuxhathisa okuhle kweqabaka.
I-Geomembrane yinto engenamanzi kunye nesithintelo esisekwe kwipolymer.
Ikakhulu yohlulwe ibe: i-polyethylene ephantsi (LDPE) geomembrane, i-polyethylene ephezulu yoxinaniso (HDPE) geomembrane, kunye ne-EVA geomembrane.
1. Ububanzi kunye nobungqingqwa obucacileyo bugqityiwe.
2. Inokumelana noxinzelelo olukhulu lokusingqongileyo kunye nokumelana nokugqwesa kweekhemikhali.
3. Ukumelana nokugqwesa kweekhemikhali.
4. Inomlinganiselo omkhulu wokushisa wokusebenza kunye nobomi benkonzo ende.
5. Isetyenziswa kwiindawo zokulahla inkunkuma, iindawo zokugcina iintsalela zezimbiwa, uthintelo lwe-canal seepage, uthintelo lwe-embankment seepage, kunye neeprojekthi ze-subway.
Eyona ndlela iphambili yayo kukwahlula indawo yokuvuza kwedama lomhlaba ngokungabi namanzi kwefilim yeplastiki, imelane noxinzelelo lwamanzi kwaye ilungelelanise noguquko lomzimba wedama ngamandla awo amakhulu kunye nobude;Ilaphu elingalukwanga luhlobo lwemathiriyeli emifutshane yefayibha yepolymer, eyenziwe ngokuhlatywa ngenaliti okanye ibhondi eshushu, kwaye inamandla aphezulu kunye nokwandiswa.Xa idityaniswe nefilimu yeplastiki, ayikhuphi nje kuphela amandla okuqina kunye nokumelana nokugqabhuka kwefilimu yeplastiki, kodwa ikwanyusa i-coefficient yokukhuhlana komphezulu woqhagamshelwano ngenxa yobuso oburhabaxa belaphu elingalukwanga, elinceda ukuzinza kwecomposite. geomembrane kunye umaleko okhuselayo.Kwangaxeshanye, banokumelana ne-corrosion entle kwiibhaktheriya kunye nentshukumo yeekhemikhali, abayoyiki i-asidi, i-alkali, kunye nokukhukuliseka kwetyuwa, kwaye banobomi obude benkonzo xa besetyenziswa kwindawo emnyama.
