Geomembrane yeLinear Low Density Polyethylene (LLDPE)
Tsananguro pfupi:
Geomembrane yeLinear low-density polyethylene (LLDPE) ipolymer inodzivirira kubuda kwemvura yakagadzirwa ne linear low-density polyethylene (LLDPE) resin sechinhu chikuru chinoshandiswa kuburikidza nekuputira, firimu rakaumbwa nezvimwe zvinhu. Inobatanidza humwe hunhu hwe high-density polyethylene (HDPE) uye low-density polyethylene (LDPE), uye ine zvakanakira zvakasiyana mukushanduka-shanduka, kuramba kubhoorwa uye kugona kuchinjika pakuvaka.

Hunhu hweKushanda
Kuramba Kusviba Kwakanaka
Nechimiro chayo chemolecular chakakora uye ine permeability yakaderera, LLDPE geomembrane inogona kudzivirira kubuda kwemvura zvinobudirira. Mhedzisiro yayo yekubuda kwemvura yakafanana neyeHDPE geomembrane, zvichiita kuti ishande zvakanyanya kumapurojekiti anoda kudzora kubuda kwemvura.
Kuchinjika Kwakanaka
Inoratidza kuchinjika kukuru uye haikurumidzi kupwanyika kana tembiricha yakaderera, ine huremu hwekupisa hunosvika -70°C kusvika 80°C. Izvi zvinoibvumira kuti ikwanise kuchinjika kune nzvimbo dzisina kurongeka kana nharaunda dzine simba rinoshanduka, senge mapurojekiti ekuchengetedza mvura munzvimbo dzine makomo dzine nzvimbo dzakaoma.
Kuramba Kuboorwa Kwakasimba
Kamudzira kacho kakasimba, uye kanodzivirira kubvaruka nekurovera zviri nani pane keHDPE. Panguva yekuvaka, kanogona kuramba kupwanywa nematombo kana zvinhu zvakapinza, zvichideredza kukuvara netsaona uye kuvimbika kwepurojekiti.
Kugona Kuchinja-chinja Kuvakwa Kwakanaka
Inogona kubatanidzwa nekupisa - kunyunguduka kwesimbi, uye simba rekubatana kwacho rakakura, zvichiita kuti mvura isadonhe zvakanaka. Panguva imwe chete, kugona kwayo kupfava kunoita kuti ive nyore kukotama nekutambanudza panguva yekuvaka, uye inogona kukodzera zviri nani hwaro hwakaoma hwakadai sevhu risina kuenzana uye nzvimbo dzakadzika dzegomba, zvichideredza kuoma kwekuvaka.
Kuramba Kuora Kwemakemikari Kwakanaka
Ine kugona kwakati kwekudzivirira ngura yeasidhi, alkali, uye munyu, uye yakakodzera kune dzimwe nzvimbo dzisingasvibi mvura. Inogona kutsungirira kuparadzwa kwemakemikari akasiyana-siyana kusvika pamwero wakati uye kuwedzera hupenyu hwebasa.
Minda Yekushandisa
Mapurojekiti Ekuchengetedza Mvura
Yakakodzera mapurojekiti asingapindi mvura mumatangi madiki nepakati, migero, uye matangi ekuchengetera mvura, kunyanya munzvimbo dzine nzvimbo dzakaoma kana nzvimbo dzisina kuenzana, dzakadai sekuvakwa kwemadhamu ekuongorora mvura paLoess Plateau, uko kuchinjika kwayo kwakanaka uye kushanda kwayo kusingapindi mvura kunogona kushandiswa. Kune mapurojekiti ekuchengetedza mvura kwenguva pfupi kana mwaka, akadai sematangi ekuchengetera mvura nekukasika, mabhenefiti ayo ekuvaka zviri nyore uye mutengo wakaderera zvinoita kuti ive sarudzo yakanaka.
Mapurojekiti ekuchengetedza zvakatipoteredza
Inogona kushandiswa senzvimbo yekusvinira mvura kwenguva pfupi - nzvimbo isingasvini mvura yekuisa marara madiki, nzvimbo isingasvini mvura yekuisa mvura yekuisa mumadziva, uye nzvimbo dzekuisa mvura yetsvina mumaindasitiri (munzvimbo dzisingasvini zvakanyanya), zvichibatsira kudzivirira kubuda kwetsvina uye kuchengetedza nharaunda yakapoteredza.
Kurima neKurima kweMvura
Inoshandiswa zvakanyanya mukudzivirira kubuda kwemvura mumadziva ehove nemadziva eshrimp, izvo zvinogona kudzivirira kubuda kwemvura zvinobudirira uye kuvandudza mashandiro ezviwanikwa zvemvura. Inogona zvakare kushandiswa kudzivirira kubuda kwemvura mumatangi ekuchengetera mvura yekurima, biogas digesters, uye kudzivirira hunyoro nemidzi pasi pemagreenhouse, uye inogona kuchinjika nekukanganisika kwevhu nekuda kwekuchinjika kwaro.
Kufambisa uye Uinjiniya hweManispa
Inogona kushandiswa senzvimbo inochengetedza hunyoro pamigero, ichitsiva nzvimbo dzejecha dzechinyakare uye ichideredza mari yepurojekiti. Inogona zvakare kushandiswa pakuparadzanisa makomba emapaipi epasi pevhu uye nzira dzetambo kudzivirira nzvimbo dzepasi pevhu kubva mukukukurwa kwemvura.
