Geomembrane ya Linear Low Density Polyethylene (LLDPE)
Kufotokozera Kwachidule:
Geomembrane ya Linear low-density polyethylene (LLDPE) ndi chinthu chopangidwa ndi utomoni wa linear low-density polyethylene (LLDPE) ngati chinthu chachikulu chopangira zinthu pogwiritsa ntchito blow molding, cast film ndi njira zina. Chimaphatikiza zina mwa makhalidwe a high-density polyethylene (HDPE) ndi low-density polyethylene (LDPE), ndipo chili ndi ubwino wapadera pakusinthasintha, kukana kubowoka ndi kusinthasintha kwa kapangidwe.

Makhalidwe Ogwira Ntchito
Kukana Kwambiri Kutuluka kwa Madzi
Ndi kapangidwe ka molekyulu kolimba komanso kotsika kwa permeability, geomembrane ya LLDPE imatha kuletsa kutulutsa madzi. Mphamvu yake yoteteza kutuluka kwa madzi imafanana ndi ya geomembrane ya HDPE, zomwe zimapangitsa kuti ikhale yogwiritsidwa ntchito kwambiri pamapulojekiti omwe amafuna kuwongolera kutuluka kwa madzi.
Kusinthasintha Kwabwino
Imasinthasintha bwino kwambiri ndipo siimatha kusweka mosavuta kutentha kotsika, ndipo imatha kupirira kutentha kuyambira - 70°C mpaka 80°C. Izi zimathandiza kuti igwirizane ndi malo osakhazikika kapena malo okhala ndi mphamvu yosinthasintha, monga mapulojekiti osamalira madzi m'malo amapiri okhala ndi malo ovuta.
Kukana Kubowola Kwamphamvu
Nembanembayo ndi yolimba kwambiri, ndipo kukana kwake kung'ambika ndi kugwedezeka ndikwabwino kuposa kwa nembanemba yosalala ya HDPE. Pakumanga, imatha kupirira kubowoka kwa miyala kapena zinthu zakuthwa, kuchepetsa kuwonongeka mwangozi ndikuwonjezera kudalirika kwa polojekitiyi.
Kusinthasintha Kwabwino Pakamangidwe
Ikhoza kulumikizidwa ndi kusungunula kotentha, ndipo mphamvu ya cholumikizira ndi yayikulu, zomwe zimapangitsa kuti madzi asalowe bwino. Nthawi yomweyo, kusinthasintha kwake bwino kumapangitsa kuti ikhale yosavuta kupindika ndi kutambasula panthawi yomanga, ndipo imatha kuyika bwino maziko ovuta monga nthaka yosafanana ndi malo otsetsereka a maziko, zomwe zimachepetsa zovuta zomangira.
Kukana Kudzikundikira kwa Mankhwala
Ili ndi mphamvu yolimbana ndi dzimbiri la asidi, alkali, ndi mchere, ndipo ndi yoyenera pazochitika zambiri zomwe sizingalowe m'madzi. Imatha kupirira kuwonongeka kwa mankhwala osiyanasiyana mpaka pamlingo winawake ndikuwonjezera nthawi yogwira ntchito.
Minda Yofunsira
Mapulojekiti Osamalira Madzi
Ndi yoyenera mapulojekiti osalowa madzi a m'mabowo ang'onoang'ono ndi apakatikati, ngalande, ndi matanki osungiramo zinthu, makamaka m'madera okhala ndi malo ovuta kapena malo osagwirizana, monga kumanga madamu oyendera pa Loess Plateau, komwe kusinthasintha kwake kwabwino komanso magwiridwe antchito osalowa madzi angagwiritsidwe ntchito. Pamapulojekiti osungira madzi kwakanthawi kapena nyengo, monga matanki osungira madzi adzidzidzi, ubwino wake womanga mosavuta komanso mtengo wotsika zimapangitsa kuti ikhale chisankho chabwino.
Mapulojekiti Oteteza Zachilengedwe
Itha kugwiritsidwa ntchito ngati malo osataya madzi kwakanthawi - osataya madzi m'malo otayira zinyalala ang'onoang'ono, malo osataya madzi m'madzi - osataya madzi m'madzi, ndi malo oikira madzi m'madzi a m'mafakitale (m'malo omwe sawononga kwambiri), kuthandiza kupewa kutuluka kwa zinthu zoipitsa madzi ndikuteteza chilengedwe chozungulira.
Ulimi ndi Ulimi wa Zam'madzi
Imagwiritsidwa ntchito kwambiri popewa kutuluka kwa madzi m'madziwe a nsomba ndi m'madziwe a nkhanu, zomwe zingalepheretse kutuluka kwa madzi ndikuwonjezera kugwiritsa ntchito bwino madzi. Ingagwiritsidwenso ntchito popewa kutuluka kwa madzi m'matanki osungiramo ulimi, zogayira biogas, komanso kuletsa chinyezi ndi mizu kusungunuka pansi pa nyumba zobiriwira, ndipo imatha kusintha nthaka kuti isasinthe pang'ono chifukwa cha kusinthasintha kwake.
Mayendedwe ndi Uinjiniya wa Municipal
Itha kugwiritsidwa ntchito ngati gawo loteteza chinyezi pa misewu, kusintha miyala yachikhalidwe komanso kuchepetsa ndalama zomwe zimagwiritsidwa ntchito pomanga. Itha kugwiritsidwanso ntchito pochotsa madzi m'ngalande za mapaipi ndi ngalande za chingwe kuti madzi asagwe pansi pa nthaka.
