Geomembrane yakatsetseka
Tsananguro pfupi:
Geomembrane yakatsetseka inowanzogadzirwa nechinhu chimwe chete chepolymer, senge polyethylene (PE), polyvinyl chloride (PVC), nezvimwewo. Pamusoro payo pakanaka uye pakadzikama, pasina magadzirirwo kana zvidimbu zvinooneka.

Geomembrane yakatsetseka inowanzogadzirwa nechinhu chimwe chete chepolymer, senge polyethylene (PE), polyvinyl chloride (PVC), nezvimwewo. Pamusoro payo pakanaka uye pakadzikama, pasina magadzirirwo kana zvidimbu zvinooneka.
- Hunhu
- Kushanda zvakanaka kwekudzivirira kubuda kwemvura: Inodzivirira kupinda kwemvura zvishoma uye inogona kudzivirira kupinda kwemvura. Inodzivirira mvura, mafuta, mishonga yemakemikari, nezvimwewo. Kudzivirira kubuda kwemvura kunogona kusvika 1×10⁻¹²cm/s kusvika 1×10⁻¹⁷cm/s, izvo zvinogona kuzadzisa zvinodiwa nemapurojekiti mazhinji zvekudzivirira kubuda kwemvura.
- Kugadzikana kwakasimba kwemakemikari: Inodzivirira acid nealkali zvakanyanya uye inodzivirira ngura. Inogona kuramba yakasimba munzvimbo dzakasiyana dzemakemikari uye haikurumidzi kukurwa nemakemikari ari muvhu. Inogona kuramba ngura yemamwe masanganiswa eacid, alkali, munyu nezvimwe zvinogadziriswa.
- Kudzivirira kupisa kwakaderera: Inogona kuramba ichichinjika zvakanaka uye ine hunhu hwakanaka hwemakanika munzvimbo inodziya kupisa kwakaderera. Semuenzaniso, mamwe ma geomembrane akatsetseka epolyethylene emhando yepamusoro achiri nekusimba kwakati pakati pe -60℃ kusvika -70℃ uye haasi nyore kutyoka.
- Kuvakwa kuri nyore: Pamusoro payo pakanaka uye kukwirirana kwechinhu kudiki, izvo zviri nyore kuisa panzvimbo dzakasiyana-siyana uye pasi. Inogona kubatanidzwa nekusveta, kusunga uye dzimwe nzira. Kumhanya kwekuvaka kunokurumidza uye mhando yacho iri nyore kudzora.
Maitiro Ekugadzira
- Nzira yekuumba nekubvisa simbi: Zvinhu zvakabikwa zvepolymer zvinopiswa kusvika zvanyungudutswa uye zvinoburitswa kuburikidza neextruder kuti zvigadzire gomba risina chinhu. Zvadaro, mweya wakamanikidzwa unofuridzirwa mugomba risina chinhu kuti rikure uye rinamatire kumould kuti ritonhore uye riumbe. Pakupedzisira, geomembrane yakatsetseka inowanikwa nekucheka. Geomembrane inogadzirwa nenzira iyi ine ukobvu hwakafanana uye hunhu hwakanaka hwemakanika.
- Nzira yekuisa calender: Zvinhu zvakabikwa zvepolymer zvinodziiswa zvobva zvaburitswa uye zvinotambanudzwa nemaroller akawanda ecalender kuti zvigadzire firimu rine ukobvu hwakati uye upamhi hwakati. Mushure mekutonhora, geomembrane yakatsetseka inowanikwa. Maitiro aya ane kushanda kwepamusoro uye upamhi hwakakura hwechigadzirwa, asi kufanana kweukobvu kwacho hakuna kunaka.
Minda Yekushandisa
- Purojekiti yekuchengetedza mvura: Inoshandiswa pakurapa nzvimbo dzekuchengetedza mvura dzakadai sematangi, madhamu, nemigero. Inogona kudzivirira kubuda kwemvura zvinobudirira, kuvandudza kuchengetwa kwemvura uye kushanda zvakanaka kwemapurojekiti ekuchengetedza mvura, uye kuwedzera hupenyu hwebasa reprojekiti.
- Dura remarara: Senzira yekudzikamisa mvura pasi nepadivi pedura remarara, inodzivirira dura remarara kuti risasvibise ivhu nemvura yepasi uye inodzivirira nharaunda yakapoteredza.
- Chivako chisingapindi mvura: Chinoshandiswa sechikamu chinodzivirira mvura kupinda mudenga, pasi pevhu, muimba yekugezera nedzimwe nzvimbo dzechivako kudzivirira mvura yemvura, mvura yepasi pevhu nedzimwe hunyoro kupinda muchivako uye kuvandudza mashandiro echivako asingapindi mvura.
- Nzvimbo yekugadzira: Inoshandiswa kudzivirira kudonha kwemvura mumadhamu ekugadzira, madziva ekugadzira, nzvimbo dzemvura dzegorofu, nezvimwewo, kuchengetedza kugadzikana kwemvura, kuderedza kurasikirwa nemvura, uye kupa hwaro hwakanaka hwekugadzira nzvimbo.
Magadzirirwo uye Zviratidzo zveUnyanzvi
- Magadzirirwo: Ukobvu hwe geomembrane yakatsetseka hunowanzova pakati pe0.2mm ne3.0mm, uye hupamhi hunowanzova pakati pe1m ne8m, izvo zvinogona kugadziriswa zvichienderana nezvinodiwa nemapurojekiti akasiyana.
- Zviratidzo zvehunyanzvi: Zvinosanganisira simba rekudhonza, kureba panguva yekutyoka, simba rekubvarura kwekona yekurudyi, kuramba kudzvanywa kwemvura, nezvimwewo. Simba rekudhonza rinowanzova pakati pe5MPa ne30MPa, kureba panguva yekutyoka kuri pakati pe300% ne1000%, simba rekubvarura kwekona yekurudyi riri pakati pe50N/mm ne300N/mm, uye kuramba kudzvanywa kwemvura kuri pakati pe0.5MPa ne3.0MPa.
