Chitetezo cha chilengedwe ndi nkhani yosatha padziko lonse lapansi.Pamene chitaganya cha anthu chikukula mosalekeza, chilengedwe chapadziko lonse chawonongeka mowonjezereka.Pofuna kusunga chilengedwe cha Dziko lapansi chofunikira kuti anthu apulumuke, chitetezo ndi kayendetsedwe ka chilengedwe zidzakhazikika mkati mwa kusintha kwa chitukuko cha anthu.Pankhani yomanga makampani oteteza zachilengedwe, ma geomembranes atenga gawo losasinthika m'malo oteteza zachilengedwe m'zaka zaposachedwa.Makamaka, HDPE Geomembrane yawonetsa kutchuka kwambiri pakuletsa madzi komanso ma projekiti odana ndi masamba.
1. Kodi HDPE Geomembrane ndi chiyani?
HDPE Geomembrane, yemwe dzina lake lonse ndi "High-Density Polyethylene Geomembrane," ndi zinthu zopanda madzi komanso zotchinga zomwe zimapangidwa pogwiritsa ntchito utomoni wa polyethylene (wapakati) wochuluka kwambiri.Nkhaniyi imatsutsana kwambiri ndi kuwonongeka kwa chilengedwe, kukana kutentha, kukana kukalamba, komanso kukana kwa dzimbiri, komanso kutentha kwakukulu komwe kumagwiritsidwa ntchito (-60- + 60) ndi moyo wautali wautumiki wa zaka 50.Amagwiritsidwa ntchito kwambiri m'mapulojekiti odana ndi kufalikira kwa zinyalala monga kuteteza zinyalala zotayiramo zinyalala, kupewa kutayira zinyalala, kuteteza malo otsuka zimbudzi, kupewa kutulutsa madzi m'nyanja mochita kupanga, komanso kuchiza ma tailings.
2. Ubwino wa HDPE Geomembrane
(1) HDPE Geomembrane ndi chinthu chosinthika chosalowa m'madzi chokhala ndi coefficient yayikulu yotuluka.
(2) HDPE Geomembrane ali kutentha wabwino ndi kuzizira kukana, ndi ntchito chilengedwe kutentha kwa kutentha 110 ℃, kutentha otsika -70 ℃;
(3) HDPE Geomembrane ili ndi kukhazikika kwamankhwala abwino, imatha kukana ma acid amphamvu, alkalis, ndi dzimbiri lamafuta, ndikupangitsa kuti ikhale yabwino kwambiri yoletsa kuwononga.
(4) HDPE Geomembrane ili ndi mphamvu zolimba kwambiri, zomwe zimapatsa mphamvu zowonjezereka kuti zikwaniritse zosowa zama projekiti apamwamba kwambiri.
(5) HDPE Geomembrane ili ndi mphamvu yotsutsa nyengo, yokhala ndi mphamvu yotsutsa kukalamba, yomwe imalola kuti ipitirizebe kugwira ntchito ngakhale ndi nthawi yayitali.
(6) The HDPE Geomembrane roughened imapangitsa kukangana kwa nembanemba pamwamba.Poyerekeza ndi nembanemba yosalala yomweyi, imakhala ndi mphamvu zolimba kwambiri.Pamwamba pa nembanemba imakhala ndi tinthu tating'onoting'ono tomwe timapanga tinthu tating'onoting'ono pakati pa nembanemba ndi m'munsi pomwe nembanemba imayikidwa, zomwe zimakulitsa kwambiri mphamvu ya geomembrane.
II.Njira ndi Kugwiritsa Ntchito kwa HDPE Geomembrane M'gawo la Zotayiramo
Malo otayiramo malo pano ndi njira yomwe imagwiritsidwa ntchito kwambiri posungira zinyalala zolimba ndi zinyalala zapakhomo, zodziwika ndi mtengo wotsika, mphamvu yayikulu yopangira, komanso ntchito yosavuta.Yakhala ikugwiritsidwa ntchito kwambiri m'mayiko ndi zigawo zambiri ndipo yakhala njira yoyamba yothetsera zinyalala zapakhomo m'mayiko ambiri otukuka.
High-density polyethylene geomembrane ndizomwe zimagwiritsidwa ntchito kwambiri zotsutsana ndi zotayira.HDPE Geomembrane ndi yodziwika bwino pakati pa zinthu zopangidwa ndi polyethylene zomwe zili ndi mphamvu zapamwamba kwambiri, zokhazikika zamakemikolo, komanso magwiridwe antchito abwino kwambiri oletsa kukalamba, ndipo amayamikiridwa kwambiri ndi opanga ndi eni mafakitale otaya zinyalala.
Zotayiramo nthawi zambiri zimakhala ndi vuto la zinyalala zokhala ndi zinthu zapoizoni kwambiri komanso zovulaza, mankhwala owopsa, ndi mavuto ena.Zomwe zimagwiritsidwa ntchito mu uinjiniya zimakhala ndi zovuta kwambiri zogwiritsira ntchito, kuphatikiza mphamvu, chilengedwe, media, nthawi, ndi zina zambiri, komanso zinthu zosiyanasiyana zomwe zimayikidwa.Ubwino wa zotsatira zotsutsana ndi seepage umatsimikizira mwachindunji khalidwe laumisiri, ndipo moyo wautumiki wa geomembrane ndiwonso chinthu chachikulu chomwe chimatsimikizira moyo wa uinjiniya.Choncho, zinthu zotsutsana ndi zowonongeka zomwe zimagwiritsidwa ntchito pazitsulo zotayira pansi ziyenera kukhala ndi ntchito yabwino yotsutsa-seepage, biodegradability yabwino, ndi ntchito yabwino ya antioxidation, mwa zina.
Pambuyo pazaka zambiri za kafukufuku ndi zochitika mu bungwe lathu lofufuza za geomembrane la kampani yathu, geomembrane yomwe imagwiritsidwa ntchito mu anti-seepage system ya malo otayirako sayenera kungotsatira mfundo zaukadaulo zapadziko lonse komanso zapadziko lonse lapansi komanso kukwaniritsa zofunikira izi:
(1) Makulidwe a HDPE Geomembrane sayenera kuchepera 1.5mm.Kuchulukana kumatsimikizira kupsinjika, kulimba, kukana nkhonya, komanso kukhazikika kwa makina otayiramo zinyalala.
(2) Geomembrane ya HDPE iyenera kukhala ndi mphamvu zolimba zolimba, zomwe zingatsimikizire kuti sizidzathyoka, kung'ambika, kapena kupunduka panthawi yoika kapena kugwiritsidwa ntchito, komanso kuti zimatha kupirira mphamvu ya nthaka ndi kutaya zinyalala zokha.
(3) HDPE Geomembrane iyenera kukhala ndi kukana koboola bwino kwambiri, komwe kungawonetsetse kuti kukhulupirika kwa nembanemba kumasungidwa pakapita nthawi, komanso kuti sipadzakhala "mabowo" kapena "misozi" mu nembanemba yomwe ingayambitse kutayikira.
(4) Geomembrane ya HDPE iyenera kukhala ndi mankhwala abwino kwambiri, omwe angatsimikizire kuti sakuwonongeka kapena kuwononga ndi mankhwala a zinyalala zotayira.Iyeneranso kukhala ndi kukana kwabwino kwa kuwonongeka kwachilengedwe, zomwe zingatsimikizire kuti sizingawukidwe kapena kuwonongedwa ndi mabakiteriya, mafangasi, kapena tizilombo tating'onoting'ono tomwe tingapezeke kumalo otayirako.
(5) HDPE Geomembrane iyenera kukhala yokhoza kusunga ntchito yake yabwino kwambiri yotsutsa-seepage kwa nthawi yaitali (ie, zaka zosachepera 50), zomwe zingathe kutsimikizira moyo wautumiki wa nthawi yayitali wa makina otayiramo.
Kuphatikiza pa zomwe zili pamwambazi, HDPE Geomembrane yomwe imagwiritsidwa ntchito potayiramo zinyalala iyeneranso kupangidwa ndikuyika molingana ndi mikhalidwe yeniyeni ya malo otayirako, monga kukula kwake, malo, nyengo, geology, hydrology, etc. Mwachitsanzo, ngati kutayirako ili m'dera lomwe lili ndi madzi okwera kwambiri, lingafunike kupangidwa ndi ndondomeko yazitsulo ziwiri kapena njira yosonkhanitsa leachate yomwe ingateteze kuipitsidwa kwa madzi apansi.
Ponseponse, kugwiritsa ntchito HDPE Geomembrane muumisiri wotayiramo zinyalala ndi njira yabwino yowonetsetsera chitetezo ndi chitetezo cha chilengedwe cha malo otayirapo amakono.Posankha zipangizo zoyenera, kupanga machitidwe oyenera, ndikutsatira ndondomeko zoyenera zoyikapo ndi kukonza, zotayiramo zitha kukhala zotetezeka, zogwira mtima komanso zokhazikika.
