Semuyenzaniso, polyethylene geomembrane inogadzirwa kuburikidza nepolymerization reaction ye ethylene, uye chimiro chayo chemamorekuru chakabatana zvekuti mamorekuru emvura haakwanise kupfuura nemairi.

1.Performance Characteristics

Anti-seepage Performance:
Uku ndiko kuita kwakanyanya kukosha kwema geomembranes mukushandiswa kwemadhamu edhamu. Mageomembranes emhando yepamusoro anogona kuve nepermeability coefficient inosvika 10⁻¹² - 10⁻¹³ cm/s, inovhara zvachose mafambiro emvura. Kana ichienzaniswa neyechinyakare ivhu anti-seepage layer, iyo anti-seepage mhedzisiro inonyanya kushamisa. Semuenzaniso, pasi pekumanikidzwa kwemusoro wemvura mumwechete, huwandu hwemvura inopinda negeomembrane inongova chidimbu cheiyo kuburikidza nevhu rekudzivirira-seepage layer.
Anti-puncture Performance:
Munguva yekushandiswa kwema geomembranes pamadhamu emvura, anogona kubaiwa nezvinhu zvakapinza sematombo nemapazi mukati memuviri wedhamu. Ma geomembranes akanaka ane simba rakati wandei rinopesana nekuputika. Semuyenzaniso, mamwe akaumbwa geomembranes ane mukati faibha reinforcement layers ayo anogona zvinobudirira kuramba puncturing. Kazhinji kutaura, iyo anti-puncture simba yeanokwanisa geomembranes inogona kusvika 300 - 600N, kuve nechokwadi kuti haizokanganiswe nyore munzvimbo yakaoma yedhamu remuviri.
Kuramba Kukwegura:
Sezvo madhamu emvura ane hupenyu hurefu hwesevhisi, geomembranes inofanirwa kuve nekuramba kuchembera kwakanaka. Anti-aging agents anowedzerwa panguva yekugadzirwa kwe geomembranes, zvichiita kuti vachengetedze kushanda kwakasimba kwenguva yakareba pasi pesimba rezvakatipoteredza zvakadai se ultraviolet rays uye kuchinja kwekushisa. Semuyenzaniso, geomembranes akagadzirwa neakakosha magadzirirwo uye matekiniki anogona kuve nehupenyu hwesevhisi hwe30 - 50 makore kunze.
Deformation Adaptability:
Dhamu richaita mamwe madhirimuni akadai sekugara uye kutamiswa panguva yekuchengetwa kwemvura. Geomembranes inogona kuchinjika kune yakadaro deformation pasina kutsemuka. Semuenzaniso, vanogona kutambanudza uye kukotama kusvika pamwero wakati pamwe nekugadziriswa kwemuviri wedhamu. Simba ravo rekusimba rinowanzosvika 10 - 30MPa, richivagonesa kutsungirira kushushikana kunokonzerwa nekushandurwa kwemuviri wedhamu.

kness maererano nezvinodiwa zvepurojekiti. Ukobvu hwe geomembrane kazhinji 0.3mm kusvika 2.0mm.
- Impermeability: Ita shuwa kuti geomembrane ine yakanaka kusapinda kudzivirira mvura muvhu kuti isapinda muchirongwa.

2.Construction Key Points

Base Treatment:
Usati waisa geomembranes, chigadziko chedhamu chinofanira kunge chakati sandara uye chakasimba. Zvinhu zvakapinza, masora, ivhu rakasununguka uye matombo pamusoro pechigadziko anofanira kubviswa. Semuyenzaniso, iko kufuratira kukanganisa kwegasi kunowanzo kudiwa kuti idzorwe mukati me ± 2cm. Izvi zvinogona kudzivirira geomembrane kubva pakukwenya uye kuve nechokwadi chekubatana kwakanaka pakati pe geomembrane uye chigadziko kuitira kuti iyo anti-seepage performance igone kuitwa.
Kuisa nzira:
Geomembranes anowanzo spliced ne welding kana bonding. Kana welding, zvinodikanwa kuve nechokwadi chekuti tembiricha yekudziya, kumhanya uye kudzvanywa kwakakodzera. Semuyenzaniso, pakupisa-welding geomembranes, tembiricha yewelding inowanzova pakati pe200 - 300 °C, kumhanya kwewelding kunosvika 0.2 - 0.5m/min, uye pressure yewelding iri pakati pe0.1 - 0.3MPa kuve nechokwadi chemhando yewelding nekudzivirira. leakage matambudziko anokonzerwa nekusaita welding.
Peripheral Connection:
Kubatana kwegeomembranes nehwaro hwedhamu, makomo ari kumativi ose edhamu, nezvimwewo pamucheto wedhamu kwakakosha zvikuru. Kazhinji, migero yekumisa, kongiri capping, nezvimwe zvichagamuchirwa. Semuyenzaniso, mugero wekusungirira wakadzika 30 - 50cm wakagadzikwa pahwaro hwedhamu. Mupendero we geomembrane unoiswa mumugero we anchoring uye wakagadziriswa nevhu rakakomberedzwa zvinhu kana kongiri kuti ive nechokwadi chekuti geomembrane yakanyatso sunganidzwa nezvimiro zvakatenderedza uye kudzivirira peripheral leak.

3.Maintenance uye Inspection

Routine Maintenance:
Izvo zvinodiwa kuti ugare uchitarisa kana pane zvinokuvadza, misodzi, punctures, nezvimwewo pamusoro pe geomembrane. Semuenzaniso, panguva yekushanda kwedhamu, vashandi vekuchengetedza vanogona kuongorora kamwe chete pamwedzi, vachitarisa kutarisa geomembrane munzvimbo dzinogara dzichichinja mvura uye nzvimbo dzine madhamu makuru.
Nzira dzekuongorora:
Nzira dzisiri dzekuparadza dzekuyedza dzinogona kugamuchirwa, senge nzira yekuyedza spark. Nenzira iyi, imwe voltage inoshandiswa pamusoro pe geomembrane. Kana pane kukuvadzwa kune geomembrane, sparks dzinogadzirwa, kuitira kuti mapoinzi akakuvadzwa anogona kuwanikwa nekukurumidza. Uye zvakare, kune zvakare iyo vacuum yekuyedza nzira. Nzvimbo yakavharwa inoumbwa pakati pe geomembrane uye mudziyo wekuyedza, uye kuvepo kwekudonha mu geomembrane kunotongwa nekucherechedza shanduko yevacuum degree.
