Geomembrane liners zvinhu zvakakosha zvinoshandiswa mumapurojekiti akasiyana ekuvaka uye ezvakatipoteredza kudzivirira kubuda kwezvinwiwa nemagasi. Pakati pemhando dzakasiyana dzegeomembrane liners dziripo pamusika, HDPE (High-Density Polyethylene), PVC (Polyvinyl Chloride), uye LLDPE (Linear Low-Density Polyethylene) geomembrane liners anoshandiswa zvakanyanya. Imwe neimwe mhando yegeomembrane linerine zvimiro zvayo zvakasiyana uye mashandisirwo, zvichiita kuti zvive zvakakosha kunzwisisa mutsauko uripo pakati pazvo.
HDPE geomembrane linersinogadzirwa kubva kune yakakwira-density polyethylene, iyo thermoplastic polymer inozivikanwa nekusimba kwayo uye yakasimba zvinhu. HDPE liner anowanzo shandiswa mumashandisirwo uko akakwira makemikari kuramba uye UV kuramba inodiwa, senge mumarara emarara, mashandiro emigodhi, uye pond liners. Izvo zvinhu zvakanyanya kusimba simba uye puncture kuramba inoita kuti ive yakakodzera kune mapurojekiti anoda kusimba kwenguva refu uye dziviriro kubva kune zvakatipoteredza zvinhu.
PVC geomembrane liners, kune rumwe rutivi, inogadzirwa kubva ku polyvinyl chloride, yakagadzirwa nepurasitiki polymer inozivikanwa nekushanduka kwayo uye kuramba kumakemikari. PVC liners anowanzo shandiswa muzvishandiso uko kuchinjika uye weldability kwakakosha, senge mumudziyo wemvura, madziva ekushongedza, uye madziva ekurima. PVC geomembrane liners inozivikanwa nekureruka kwayo kwekumisikidza uye kugona kuenderana nenzvimbo dzisina kujairika, zvichiita kuti ive sarudzo yakakurumbira yemapurojekiti akasiyana emidziyo.
LLDPE geomembrane linersakagadzirwa kubva mumutsara wakaderera-density polyethylene, inochinjika uye inotsiga zvinhu inozivikanwa nekuramba kwayo kupinza uye elongation zvimiro. LLDPE liner anowanzo kushandiswa mumashandisirwo uko kuchinjika uye kurebesa kwakakosha, senge mumavharo anoyangarara, chechipiri chemukati, uye canal liner. Iko kugona kwechinhu kuenderana neiyo substrate uye kuramba punctures kunoita kuti ive yakakodzera kune mapurojekiti anoda mwero wepamusoro wekushanduka uye kusimba.
Kana uchienzanisa HDPE, PVC, uye LLDPE geomembrane liners, akati wandei misiyano yakakosha inobuda pachena. HDPE liner dzinozivikanwa nekuda kwesimba rayo rakakura uye makemikari kuramba, zvichiita kuti ive yakakodzera kune zvikumbiro uko kusimba kwenguva refu kwakakosha. PVC liners anokosheswa kuchinjika kwawo uye weldability, zvichiita kuti ave akanakira mapurojekiti anoda kuisirwa nyore uye kuenderana neasina kujairika. LLDPE liners anokosheswa nekuchinjika kwawo uye kuramba kupinza, zvichiita kuti ave akakodzera kune maapplication anoda yakakwirira yekusimba uye kurebesa.
Mukupedzisa, sarudzo pakati peHDPE, PVC, uye LLDPE geomembrane liners zvinoenderana nezvinodiwa zveprojekiti. Imwe neimwe mhando yegeomembrane linerinopa akasiyana zvivakwa uye mabhenefiti, zvichiita kuti zvive zvakakosha kufunga zvinhu zvakaita semakemikari kuramba, kuchinjika, uye puncture kuramba kana uchisarudza yakanyanya kufanira kune imwe application. Nekunzwisisa mutsauko uripo pakati peHDPE, PVC, uye LLDPE geomembrane liners, mainjiniya uye mamaneja epurojekiti vanogona kuita sarudzo dzine ruzivo kuti vaone kubudirira uye hupenyu hurefu hwemidziyo yavo uye mapurojekiti ekuchengetedza nharaunda.
