Geomembrane yosalala
Kufotokozera Kwachidule:
Geomembrane yosalala nthawi zambiri imapangidwa ndi chinthu chimodzi cha polima, monga polyethylene (PE), polyvinyl chloride (PVC), ndi zina zotero.
Mapangidwe oyambira
Geomembrane yosalala nthawi zambiri imapangidwa ndi chinthu chimodzi cha polima, monga polyethylene (PE), polyvinyl chloride (PVC), ndi zina zotero.
- Makhalidwe
- Kuchita bwino kwa anti-seepage: Ili ndi mwayi wochepa kwambiri ndipo imatha kuletsa kulowa kwa zakumwa. Zili ndi zotchinga zabwino zotsutsana ndi madzi, mafuta, mankhwala opangira mankhwala, ndi zina zotero. Mphamvu ya anti-seepage imatha kufika 1 × 10⁻¹²cm/s mpaka 1×10⁻¹⁷cm/s, yomwe imatha kukwaniritsa zofunikira za anti-seepage zamapulojekiti ambiri. .
- Kukhazikika kwamphamvu kwamankhwala: Ili ndi asidi wabwino kwambiri komanso kukana kwa alkali komanso kukana dzimbiri. Ikhoza kukhala yokhazikika m'malo osiyanasiyana amankhwala ndipo sikokoloka mosavuta ndi mankhwala omwe ali m'nthaka. Iwo akhoza kukana dzimbiri wa ndende ya asidi, zamchere, mchere ndi zina zothetsera.
- Kukana kwabwino kwa kutentha kotsika: Imatha kukhalabe osinthika komanso makina amakina pamalo otsika kwambiri. Mwachitsanzo, ma geomembranes apamwamba a polyethylene osalala akadali ndi kuthanuka kwina pa -60 ℃ mpaka -70 ℃ ndipo sizovuta kuthyoka.
- Kumanga koyenera: Pamwamba pake ndi yosalala ndipo chigawo cha mikangano ndi chaching'ono, chomwe chimakhala chosavuta kuyika pazigawo zosiyanasiyana ndi maziko. Ikhoza kugwirizanitsidwa ndi kuwotcherera, kugwirizanitsa ndi njira zina. Kuthamanga kwa zomangamanga kumathamanga ndipo khalidwe ndilosavuta kulamulira.
Njira Yopanga
- Njira yopangira nkhonya yotulutsa: Zinthu zopangira polima zimatenthedwa mpaka kusungunuka ndipo zimatulutsidwa kudzera mu chotulukapo kuti chikhale chopanda kanthu. Kenako, mpweya woponderezedwa umawomberedwa mu chubu chopanda kanthu kuti chiwonjezeke ndikumamatira ku nkhungu kuti uziziziritsa ndi kupanga. Pomaliza, geomembrane yosalala imapezeka mwa kudula. Geomembrane yopangidwa ndi njirayi imakhala ndi makulidwe a yunifolomu komanso makina abwino.
- Calendering njira: Polima zopangira ndi kutentha kenako extruded ndi kutambasula ndi angapo odzigudubuza a kalendala kupanga filimu ndi makulidwe enaake ndi m'lifupi. Pambuyo kuzirala, geomembrane yosalala imapezedwa. Njirayi imakhala ndi magwiridwe antchito apamwamba komanso m'lifupi mwazinthu zambiri, koma makulidwe ake amafanana ndi osauka.
Minda Yofunsira
- Pulojekiti yosungira madzi: Amagwiritsidwa ntchito pothana ndi vuto la madzi osungiramo madzi monga madamu, madamu, ndi ngalande. Ikhoza kuteteza madzi kuti asatayike, kupititsa patsogolo kasungidwe ka madzi ndi kayendedwe kabwino ka ntchito zosungira madzi, ndi kuwonjezera moyo wa ntchito ya polojekitiyi.
- Kutayirapo nthaka: Monga chotchinga chotchinga pansi ndi mbali ya kutayirako, chimalepheretsa otayirapo kuwononga nthaka ndi madzi apansi ndipo amateteza chilengedwe chozungulira.
- Kumanga kwamadzi: Amagwiritsidwa ntchito ngati wosanjikiza madzi padenga, pansi, bafa ndi mbali zina za nyumbayo kuti ateteze kulowa kwa madzi amvula, madzi apansi ndi chinyezi china mnyumbamo ndikuwongolera magwiridwe antchito amadzi a nyumbayo.
- Malo Opanga: Amagwiritsidwa ntchito poletsa kufalikira kwa nyanja zopangira, maiwe owoneka bwino, malo otsetsereka a gofu, ndi zina zambiri, kuti asungitse bata lamadzi, kuchepetsa kutayikira kwamadzi, ndikupereka maziko abwino a chilengedwe.
Mafotokozedwe ndi Zizindikiro Zaukadaulo
- Zofotokozera: Makulidwe a geomembrane yosalala nthawi zambiri amakhala pakati pa 0.2mm ndi 3.0mm, ndipo m'lifupi amakhala pakati pa 1m ndi 8m, omwe amatha kusinthidwa malinga ndi zosowa zama projekiti osiyanasiyana.
- Zizindikiro zaumisiri: Kuphatikizira mphamvu zamakokedwe, elongation panthawi yopuma, mphamvu yong'ambika kumanja, kukana kwa hydrostatic, etc. Mphamvu yamakokedwe imakhala pakati pa 5MPa ndi 30MPa, elongation pakupuma ndi pakati pa 300% ndi 1000%, kung'ambika koyenera. mphamvu ili pakati pa 50N/mm ndi 300N/mm, ndipo kukana kwa hydrostatic kuli pakati pa 0.5MPa ndi 3.0MPa.
