Kuchengetedza kwezvakatipoteredza inyaya isingaperi pasi rose.Sezvo nzanga yavanhu inopfuurira kukura, mhoteredzo yepasi rose yave ichikuvadzwa nomutoo unowedzera.Kuti uchengetedze nharaunda yePasi yakakosha pakurarama kwevanhu, kuchengetedzwa uye kutonga kwezvakatipoteredza kuchaiswa mukati mekushanduka kwehupenyu hwevanhu.Kana iri yekuvakwa kweindasitiri yekuchengetedzwa kwezvakatipoteredza, geomembranes yakaita basa risingadzokerike munharaunda yekuchengetedzwa kwezvakatipoteredza mumakore achangopfuura.Kunyanya, HDPE Geomembrane yakaratidza mukurumbira wakakosha mukudzivirira mvura uye anti-seepage mapurojekiti.
1. Chii chinonzi HDPE Geomembrane?
HDPE Geomembrane, ine zita rakazara rinonzi “High-Density Polyethylene Geomembrane,” chinhu chisingapindi mvura uye chinodzivirira chinogadzirwa uchishandisa (pakati) high-density polyethylene resin.Iyo nyaya ine yakanakisa kupikisa kuputika kwekushushikana kwezvakatipoteredza, kushomeka-kupisa kuramba, kuramba kuchembera, uye kushorwa kwemarara, pamwe neyakakura tembiricha yekushandiswa (-60- + 60) uye hupenyu hurefu hwebasa remakore makumi mashanu.Inoshandiswa zvakanyanya mumapurojekiti e-anti-seepage akadai sekudzivirira marara emarara emarara, kudzivirira marara emarara, kudzivirira kwesewage treatment plant seepage prevention, artificial lake seepage prevention, uye tailings treatment.
2. Zvakanakira HDPE Geomembrane
(1) HDPE Geomembrane chinhu chinochinjika chisina mvura chine yakakwira seepage coefficient.
(2) HDPE Geomembrane ine kupisa kwakanaka uye kutonhora kwekudzivirira, ine tembiricha yekushandiswa kwenzvimbo yekushisa kwepamusoro 110 ℃, tembiricha yakaderera -70 ℃;
(3) HDPE Geomembrane ine kugadzikana kwakanaka kwemakemikari, inogona kuramba yakasimba acids, alkalis, uye mafuta ekuora, zvichiita kuti ive yakanakisa anticorrosive material.
(4) HDPE Geomembrane ine simba rakanyanya kusimba, ichipa simba rakasimba rekusangana nezvinodiwa zvemapurojekiti einjiniya epamusoro.
(5) HDPE Geomembrane ine yakasimba yemamiriro ekunze kuramba, ine simba rekurwisa kuchembera kuita, ichiibvumira kuchengetedza kuita kwayo kunyangwe nekuratidzwa kwenguva refu.
(6) Iyo yakaomeswa HDPE Geomembrane inosimudzira friction performance ye membrane kumeso.Kana ichienzaniswa neyakafanana dhizaini yakatsetseka membrane, ine yakasimba tensile simba.Iyo yakakasharara yemembrane ine rough particles pamusoro payo, iyo inozogadzira diki gap layer pakati pe membrane nechigadziko kana membrane yaiswa, zvakanyanya kusimudzira kugona kwekubereka kwegeomembrane.
II.Matekinoroji uye mashandisirwo eHDPE Geomembrane muMunda weLandfills
Nzvimbo dzekurasira marara pari zvino ndiyo inonyanya kushandiswa nzira yekurapa tsvina yakasimba uye marara emumba, inoratidzwa nemutengo wakaderera, hukuru hwekugadzirisa, uye kushanda kuri nyore.Yakave ichishandiswa zvakanyanya munyika dzakawanda uye matunhu uye yanga iri nzira yekutanga yekurapa marara emumba munyika dzakawanda dzakabudirira.
High-density polyethylene geomembrane ndiyo inonyanya kushandiswa anti-seepage zvinhu mumarara.HDPE Geomembrane inomira pakati pezvigadzirwa zvepolyethylene zvakatevedzana zvine simba rayo repamusoro, zvimiro zvemakemikari zvakagadzikana, uye mashandiro akanaka ekurwisa kuchembera, uye inokosheswa zvakanyanya nevagadziri uye varidzi vemaindasitiri ekurasira.
Kuraswa kwemarara kunowanzo sanganisira dambudziko releachate ine zvinhu zvine muchetura uye zvinokuvadza, makemikari ane njodzi, uye mamwe matambudziko.Izvo zvinhu zvinoshandiswa muinjiniya zvine zvakanyanya kuomarara mamiriro ekushandisa, kusanganisira zvinhu zvesimba, zvisikwa, midhiya, nguva, nezvimwe, pamwe nezvinhu zvakasiyana zvakasimudzwa.Hunhu hweiyo anti-seepage mhedzisiro inotaridza zvakananga hutano hweinjiniya, uye hupenyu hwesevhisi yegeomembrane zvakare ndicho chinhu chikuru chinotaridza hupenyu hweinjiniya.Naizvozvo, izvo zvinopokana-seepage zvinhu zvinoshandiswa kumarara emarara zvinofanirwa kuve neakanaka anti-seepage performance, yakanaka biodegradability, uye yakanaka antioxidation performance, pakati pezvimwe zvinhu.
Mushure memakore ekutsvagisa nekuita mukambani yedu geomembrane research Institute, iyo geomembrane inoshandiswa muanti-seepage sisitimu yenzvimbo dzekurasira haifanire kungoenderana neazvino nyika neyekunze tekinoroji zviyero asi zvakare kusangana nezvinotevera zvinodiwa:
(1) Ukobvu hweHDPE Geomembrane haifanire kunge iri pasi pe1.5mm.Ukobvu hunotaridza zvakananga mamiriro ekushushikana, kusimba, kuramba kwepuncture, uye kugadzikana kweiyo landfill liner system.
(2) Iyo HDPE Geomembrane inofanira kuva nesimba rakasimba rekusimba, iyo inogona kuve nechokwadi kuti haizoputsi, kubvarura, kana kukanganisa panguva yekuisa kana kushandiswa, uye kuti inogona kumira nesimba revhu uye tsvina yemarara pachayo.
(3) HDPE Geomembrane inofanirwa kuve neyakanakisa puncture kuramba, iyo inogona kuve nechokwadi kuti kuperera kwe membrane kunochengetedzwa nekufamba kwenguva, uye kuti hakuzove ne "maburi" kana "misodzi" mu membrane inogona kutungamira mukudonha.
(4) Iyo HDPE Geomembrane inofanirwa kunge iine yakanakisa makemikari kuramba, iyo inogona kuve nechokwadi kuti haina kukuvadzwa kana corrored nemakemikari anoumbwa nemarara emarara.Inofanirawo kuve nekupikisa kwakanaka kwekuparara kwebiological, iyo inogona kuvimbisa kuti haizorwiswa kana kuderedzwa nebhakitiriya, fungi, kana mamwe ma microorganisms anogona kuwanikwa munzvimbo yemarara.
(5) HDPE Geomembrane inofanira kukwanisa kuchengetedza kushanda kwayo kwakanakisisa kwe-anti-seepage kwenguva yakareba (kureva, makore angangoita makumi mashanu), iyo inogona kuve nechokwadi chehupenyu hurefu hwebasa remararamiro emarara.
Pamusoro pezvinodiwa pamusoro apa, HDPE Geomembrane inoshandiswa mumarara inofanirawo kugadzirwa uye kuiswa maererano nemamiriro chaiwo enzvimbo yekurasira, sehukuru hwayo, nzvimbo, mamiriro ekunze, geology, hydrology, nezvimwewo. inowanikwa munzvimbo ine matafura emvura akakwirira, inogona kunge ichida kugadzirwa nekaviri lining system kana leachate collection system inogona kudzivirira kusvibiswa kwepasi.
Pakazere, kushandiswa kweHDPE Geomembrane muinjiniya yekurasira inzira inoshanda yekuve nechokwadi chekuchengetedza uye kuchengetedzwa kwezvakatipoteredza kweanorasira marara.Nekusarudza zvinhu zvakakodzera, kugadzira masisitimu akakodzera, uye nekutevera maitiro akakodzera ekumisikidza nekugadzirisa, marara anogona kuve akachengeteka, anoshanda zvakanyanya, uye akasimba.
