HDPE Geomembrane Nrog Smooth nto
Khoom piav qhia:
HDPE membrane tseem hu ua high density polyethylene membrane, HDPE geomembrane, HDPE impermeable membrane. Nws HDPE yog crystalline heev, uas tsis yog-polar thermoplastic resin. Cov tsos ntawm thawj HDPE yog milky dawb, thiab nws yog translucent rau qee yam hauv seem nyias. HDPE muaj cov khoom tiv thaiv corrosion zoo, cov khoom siv hluav taws xob, cov khoom tsis muaj dej noo, cov khoom tiv thaiv, thiab lub zog tensile siab, yog li nws yog qhov tsim nyog rau engineering seepage tiv thaiv, aquaculture seepage tiv thaiv, roj tank seepage tiv thaiv, hauv qab daus seepage tiv thaiv, dag pas dej seepage tiv thaiv thiab lwm yam teb.
Nta:
1. High anti-seepage coefficient - cov yeeb yaj kiab los tiv thaiv cov yeeb yaj kiab muaj cov nyhuv los tiv thaiv cov dej tsis zoo uas cov khoom siv dej tsis zoo sib xws. , uas tuaj yeem kov yeej qhov tsis sib xws ntawm lub hauv paus nto, thiab cov dej vapor permeability coefficient K <= 1.0 * 10-13gcm / ccm2spa;
2. Kev ua haujlwm tiv thaiv kev laus - cov yeeb yaj kiab los tiv thaiv cov yeeb yaj kiab muaj kev tiv thaiv kev laus zoo, tiv thaiv ultraviolet thiab tiv thaiv kev puas tsuaj, thiab tuaj yeem siv los ntawm txhais tes. Kev pabcuam lub neej ntawm cov khoom siv yog 50-70 xyoo, muab cov khoom zoo rau kev tiv thaiv ib puag ncig;
3. Lub zog txhua yam - lub impermeable daim nyias nyias muaj lub zog zoo txhua yam, lub zog tensile thaum so yog 28MPa, thiab elongation ntawm so yog 700%;
4. Cog cag kuj - HDPE impermeable daim nyias nyias muaj zoo heev puncture kuj thiab muaj peev xwm tiv taus feem ntau cov hauv paus hniav;
5. Chemical stability – Lub impermeable daim nyias nyias muaj cov tshuaj zoo heev stability thiab yog dav siv nyob rau hauv dej phwj kho mob, tshuaj tiv thaiv pas dej ua ke, thiab landfills. Kub thiab kub tsis kam, asphalt, roj thiab tar kuj, acid, alkali, ntsev thiab lwm yam ntau tshaj li 80 hom muaj zog acid thiab alkali tshuaj nruab nrab corrosion;
6. Ceev ceev kev tsim kho - lub anti-seepage daim nyias nyias muaj qhov yooj yooj yim, muaj ntau yam specifications thiab ntau yam ntaub ntawv nteg kom tau raws li cov anti-seepage yuav tsum tau ntawm txawv tej yaam num, siv kub-melt welding, vuam seam zog yog siab, kev tsim kho yog yooj yim, ceev thiab noj qab nyob zoo;
7. Tus nqi qis thiab kev ua haujlwm siab - HDPE anti-seepage membrane txais cov thev naus laus zis tshiab los txhim kho cov nyhuv anti-seepage, tab sis cov txheej txheem ntau lawm yog kev tshawb fawb thiab nrawm, yog li tus nqi ntawm cov khoom yog qis dua li cov khoom siv dej tsis zoo. Kom txuag tau li ntawm 50% ntawm tus nqi;
8. Kev tiv thaiv ib puag ncig thiab tsis muaj tshuaj lom - Cov ntaub ntawv siv los tiv thaiv cov dej ntws tawm yog txhua yam khoom tsis muaj tshuaj lom thiab tsis zoo rau ib puag ncig. Lub hauv paus ntsiab lus ntawm anti-seepage yog qhov hloov pauv ntawm lub cev zoo tib yam thiab tsis tsim cov tshuaj phem. Nws yog qhov kev xaiv rau kev tiv thaiv ib puag ncig, kev yug me nyuam thiab cov pas dej haus.
Kev siv:
Feem ntau yog siv rau hauv kev pov tseg, dej phwj tuaj thiab cov kua dej pov tseg, kev txuag dej, kev ua liaj ua teb, kev thauj mus los, kev tsheb ciav hlau ceev, tunnels, tshav dav hlau, tshav dav hlau, vaj tsev, toj roob hauv pes thiab lwm yam dej num tiv thaiv.
