I-Geomembrane ye-Linear Low Density Polyethylene (LLDPE)
Inkcazo emfutshane:
I-geomembrane ye-polyethylene ene-low-density (LLDPE) ene-linear low-density yi-polymer engangenisi amanzi eyenziwe nge-linear low-density polyethylene (LLDPE) resin njengezinto eziphambili ezisetyenziswa ekubumbeni, ifilimu ephosweyo kunye nezinye iinkqubo. Idibanisa ezinye zeempawu ze-polyethylene ene-high-density (HDPE) kunye ne-polyethylene ene-low-density (LDPE), kwaye ineengenelo ezikhethekileyo zokuguquguquka, ukumelana nokugqobhoza kunye nokuzivumelanisa nolwakhiwo.

Iimpawu zokusebenza
Ukumelana Okuhle Kokuntywila
Njengoko inesakhiwo esixineneyo seemolekyuli kunye ne-coefficient ephantsi yokuphuma kwamanzi, i-geomembrane ye-LLDPE inokuthintela ngokufanelekileyo ukuvuza kolwelo. Isiphumo sayo sobungqina bokuvuza kwamanzi sifana neso se-geomembrane ye-HDPE, nto leyo eyenza ukuba isetyenziswe ngokubanzi kwiiprojekthi ezifuna ulawulo lokuphuma kwamanzi.
Ukuguquguquka Okulungileyo
Ibonakalisa ukuguquguquka okumangalisayo kwaye ayiqhawuki lula kumaqondo obushushu aphantsi, inomlinganiselo wokumelana nobushushu omalunga ne -70°C ukuya kuma-80°C. Oku kuyivumela ukuba ikwazi ukuziqhelanisa neendawo ezingalinganiyo okanye iindawo ezinoxinzelelo oluguquguqukayo, ezifana neeprojekthi zokugcina amanzi kwiindawo zeentaba ezineendawo ezinzima.
Ukumelana nokubhoboza okunamandla
I-membrane iqinile kakhulu, kwaye ukumelana kwayo nokukrazuka kunye nokuchaphazeleka kungcono kune-HDPE membranes ezithambileyo. Ngexesha lokwakhiwa, inokumelana ngcono nokubhoboka kwamatye okanye izinto ezibukhali, inciphisa umonakalo owenzekileyo kwaye iphucule ukuthembeka kweprojekthi.
Ukulungelelaniswa Kokwakha Okulungileyo
Ingadityaniswa nge-hot-melt welding, kwaye amandla ejoyinti aphezulu, okuqinisekisa ukuthembeka kokuthintela ukuvuza kwamanzi. Kwangaxeshanye, ukuguguleka kwayo okuhle kwenza kube lula ukugoba nokulula ngexesha lokwakha, kwaye inokulingana ngcono neziseko ezintsonkothileyo ezifana nemizimba yomhlaba engalinganiyo kunye namathambeka eembobo zesiseko, okunciphisa ubunzima bokwakha.
Ukumelana kakuhle nokugqwala kweekhemikhali
Inamandla athile okumelana nokugqwala kwezisombululo ze-asidi, i-alkali, kunye netyuwa, kwaye ifanelekile kwiimeko ezininzi eziqhelekileyo zokungena kwamanzi. Iyakwazi ukumelana nokugqwala kwezinto ezahlukeneyo zeekhemikhali ukuya kuthi ga kwinqanaba elithile kwaye yandise ubomi benkonzo.
IiNdawo zeSicelo
Iiprojekthi Zokonga Amanzi
Ifanelekile kwiiprojekthi ezingangeni amanzi ezikwiindawo zokugcina amanzi ezincinci neziphakathi, imijelo, kunye neetanki zokugcina amanzi, ingakumbi kwiindawo ezinemihlaba enzima okanye iindawo zokuhlala ezingalinganiyo, njengokwakhiwa kwamadama okujonga amanzi kwiLoess Plateau, apho ukuguquguquka kwayo okuhle kunye nokusebenza kwayo okungangeni amanzi kungasetyenziswa khona. Kwiiprojekthi zokugcina amanzi zexesha elifutshane okanye zexesha elithile, ezifana neetanki zokugcina amanzi ezingxamisekileyo zembalela, iingenelo zayo zokwakha ezilula kunye neendleko eziphantsi zenza ukuba ibe lukhetho olufanelekileyo.
Iiprojekthi zoKhuseleko lweNdalo
Ingasetyenziswa njengomaleko okwethutyana wokuvuza - othintela ukuvuza kwiindawo ezincinci zokulahla inkunkuma, othintela ukuvuza - othintela ukuvuza kwamachibi, kunye neengqimba zamachibi amanzi amdaka emizi-mveliso (kwiimeko ezingenakonakalisa kakhulu), ukunceda ekuthinteleni ukuvuza kongcoliseko kunye nokukhusela okusingqongileyo okungqongileyo.
Ezolimo kunye nokuFuywa kweZilwanyana zasemanzini
Isetyenziswa kakhulu ekuthinteleni ukuvuza kwamanzi emachibini eentlanzi kunye namachibi ee-shrimp, nto leyo enokuthintela ukuvuza kwamanzi ngempumelelo kwaye iphucule ukusetyenziswa kakuhle kwemithombo yamanzi. Ingasetyenziselwa ukuthintela ukuvuza kwamanzi kwiitanki zokugcina ukunkcenkceshela kwezolimo, ii-biogas digesters, kunye nokwahlulwa komswakama kunye nokungangeni kweengcambu ezantsi kwezindlu zokugcina izityalo, kwaye inokuziqhelanisa nokuguquguquka okuncinci komhlaba ngenxa yokuguquguquka kwawo.
Uthutho kunye noBunjineli boMasipala
Ingasetyenziswa njengomaleko othintela ukufuma kwiibhedi zendlela, ithathe indawo yomaleko wegrabile wendabuko kwaye inciphise iindleko zeprojekthi. Ingasetyenziselwa ukwahlukanisa imibhobho engaphantsi komhlaba kunye nemijelo yekhebula ukuze kukhuselwe amanzi angaphantsi komhlaba.
