Ma geomembrane e polyethylene (HDPE) ane huwandu hwakanyanya hwekurasira marara

Ma geomembrane e polyethylene (HDPE) ane density yakakura yekuisa marara mudura Mufananidzo wakaratidzwa

Tsananguro pfupi:

Muchina weHDPE geomembrane liner wakaumbwa nemhepo yakagadzirwa nepolyethylene polymer. Basa rayo guru nderekudzivirira kubuda kwemvura uye kupwa kwegasi. Zvichienderana nekugadzirwa kwezvinhu, unogona kukamurwa kuita HDPE geomembrane liner uye EVA geomembrane liner.

Tsananguro yeZvigadzirwa

HDPE geomembrane ndeimwe yezvinhu zve geosynthetic, ine simba rakanaka rekudzivirira kukanganiswa kwezvakatipoteredza, inodzivirira kupisa kwakaderera, inodzivirira kukwegura, inodzivirira ngura, pamwe chete nekupisa kwakakura uye hupenyu hurefu, inoshandiswa zvakanyanya mukusapinda kwemarara epamba, kusapinda kwemarara akasimba, kusapinda kwetsvina yekuchenesa, kusapinda kwemvura mudziva rekugadzira, kurapwa kwemasuweji nemamwe mapurojekiti ekusapinda kwemvura.

Hunhu hweKushanda

1. Haina zvekuwedzera zvemakemikari, haipiswi nekupisa, ichinhu chekuvaka chine hushamwari kune zvakatipoteredza.
2. Ine hunhu hwakanaka hwemakanika, inopindira zvakanaka mumvura, uye inogona kuramba ngura, inodzivirira kukwegura.
3. Inodzivirira zvakasimba, inodzivirira ngura, chimiro chayo chakapfava, uye ine kushanda zvakanaka kwemvura.
4. Ine coefficient yakanaka yekukweshana uye simba rekukweshana, ine simba rekusimbisa geotechnical.
5. Nekupatsanurwa, kusefa, kudhonza mvura, dziviriro, kugadzikana, kusimbisa uye mamwe mabasa.
6. Inogona kuchinjika kuhwaro husina kuenzana, inogona kuramba kukuvara kwekuvakwa kwekunze, kukambaira kunova kudiki.
7. Kuenderera mberi kwese kwakanaka, huremu hwakareruka, kuvakwa kuri nyore.
8. Chinhu chinopindika mumvura, saka chine basa rakanaka rekuparadzanisa tsvina, chinodzivirira kupwanywa kwakasimba, saka chine basa rakanaka rekudzivirira.
