Mphepete ya anti-seepage ya maiwe a nsomba imatha kupulumutsa mtengo wodyetsa, motero imagwiritsidwa ntchito kwambiri m'mayiwe a nsomba zam'madzi ndi malo oswana nsomba m'madzi opanda mchere.Malinga ndi kafukufuku wa ma projekiti ambiri a uinjiniya, zikuwoneka kuti geomembrane impermeable ndi yovulaza kwambiri ku dziwe loyamikira komanso famu ya nsomba zoswana m'madzi.Kuonjezera apo, m'zaka zaposachedwa, minda yowonjezereka yagula geomembrane yotsutsana ndi seepage kwa maiwe a nsomba kuchokera kwa opanga anti-seepage high quality HDPE geomembrane, yomwe ndi mtundu watsopano wa geosynthetic material mu aquaculture anti-seepage industry.
Ntchito yofunika kwambiri ya anti-seepage membrane ya maiwe a nsomba ndikupewa kukhudzana kwachindunji pakati pa nsomba ndi dothi losanjikiza ndikupewa kuwononga madzi.Dziwe losasunthika la geomembrane silingapeweretu kuchuluka kwa madzi munthaka, komanso kupewa zinthu zowopsa monga ammonia, hydrogen chloride, asidi, chitsulo, ndi mankhwala ena owopsa kuti asalowe m'dziwe, zomwe zingachepetse chiopsezo cha matenda. .Moyenera kusunga ndi kulimbikitsa kukula ndi chitukuko cha nsomba.The impermeable geomembrane wa nsomba dziwe limasonyeza pamwamba yosalala kwa nsomba dziwe kuti zinyalala mu dziwe nsomba mosavuta kuthetsedwa, ndi nsomba dziwe mbali otsetsereka kutetezedwa ku dzimbiri.
The anti-seepage geomembrane ya maiwe a nsomba ndi chotchinga chachilengedwe chopanda madzi, chopangidwa ndi utomoni wa polyethylene (wapakatikati) wokwera kwambiri, wopanda zowonjezera zonse.Chogulitsacho chimakhala ndi index yotsika kwambiri (1 × 10-17) Cm/s).The filimu impermeable ndi kutentha ntchito filimu ndi 110 ℃ kutentha kwambiri, kopitilira muyeso-otsika kutentha -70 ℃, ndipo akhoza kukana amphamvu zamchere, zamchere, ndi mafuta.Kukokoloka kwa nthaka.Ili ndi mphamvu zopondereza kwambiri ndipo imatha kuganizira zofunikira zama projekiti okhazikika.Imakhala ndi kukana kukalamba kolimba, kuwonetseredwa kwa nthawi yayitali ndikusunga magwiridwe ake apachiyambi, ndipo ingagwiritsidwe ntchito pamitundu yosiyanasiyana yazachilengedwe komanso nyengo.
Malinga ndi tsatanetsatane wa katswiri waukadaulo wa dipatimenti yotsatsa ya Geomembrane, mafotokozedwe ndi zitsanzo za opanga ma geomembrane a Lingxiang fishpond omwe amapanga geomembrane nthawi zambiri amakhala mamita 6 m'lifupi ndipo pali mitundu yambiri.Koma kusiyana kwakukulu kumadalira makulidwe, omwe amatha kugawidwa pafupifupi 0.3mm, 0.3mm, 0.4mm, 1.5mm, 2.0Mm, 3.0Mm, ndi zina zotero. kukonzedwa malinga ndi zofuna za makasitomala.Nthawi zonse, 0,5 mm geomembrane angagwiritsidwe ntchito m'mayiwe nsomba.Mwachilengedwe, geomembrane yokhuthala, imakhala yabwinoko komanso moyo wautali wautumiki.Kuonjezera apo, ngati geomembrane yotsutsa-seepage imagwiritsidwa ntchito padziwe la lotus, geomembrane yotsutsana ndi seepage pamwamba pa 1.0 Mm iyenera kugwiritsidwa ntchito kuti ikhale ndi zotsatira zotsutsana ndi seepage.
