Lus piav qhia luv luv:
Cov geomembrane du feem ntau yog ua los ntawm ib qho khoom siv polymer, xws li polyethylene (PE), polyvinyl chloride (PVC), thiab lwm yam. Nws nto yog du thiab tiaj tus, tsis muaj kev ntxhib los mos los yog hais.
Basic qauv
Cov geomembrane du feem ntau yog ua los ntawm ib qho khoom siv polymer, xws li polyethylene (PE), polyvinyl chloride (PVC), thiab lwm yam. Nws nto yog du thiab tiaj tus, tsis muaj kev ntxhib los mos los yog hais.
- Yam ntxwv
- Kev ua haujlwm zoo los tiv thaiv dej: Nws muaj qhov tsis tshua muaj permeability thiab tuaj yeem tiv thaiv kev nkag mus ntawm cov kua dej. Nws muaj qhov cuam tshuam zoo tiv thaiv dej, roj, tshuaj lom neeg kev daws teeb meem, thiab lwm yam. Cov kev tiv thaiv kev tawm tsam tuaj yeem ncav cuag 1 × 10⁻¹²cm / s mus rau 1 × 10⁻¹⁷cm / s, uas tuaj yeem ua tau raws li qhov xav tau los tiv thaiv cov dej ntws ntawm feem ntau cov haujlwm. .
- Muaj zog tshuaj stability: Nws muaj cov kua qaub thiab alkali zoo heev thiab corrosion kuj. Nws tuaj yeem nyob ruaj khov hauv qhov chaw sib txawv ntawm cov tshuaj lom neeg thiab tsis yooj yim eroded los ntawm cov tshuaj hauv cov av. Nws tuaj yeem tiv thaiv corrosion ntawm qee qhov concentrations ntawm acid, alkali, ntsev thiab lwm yam kev daws teeb meem.
- Kev ua haujlwm tsis zoo ntawm qhov kub thiab txias: Nws tseem tuaj yeem tswj tau qhov hloov tau zoo thiab cov khoom siv kho tshuab hauv qhov chaw tsis muaj qhov kub thiab txias. Piv txwv li, qee qhov zoo polyethylene du geomembranes tseem muaj qee qhov elasticity ntawm -60 ℃ to -70 ℃ thiab tsis yooj yim rau tawg tawg.
- Kev tsim kho yooj yim: Qhov saum npoo yog du thiab kev sib txhuam coefficient me me, uas yooj yim rau kev tso rau ntawm ntau qhov chaw thiab hauv paus. Nws tuaj yeem txuas nrog vuam, kev sib txuas thiab lwm txoj hauv kev. Kev tsim kho nrawm nrawm thiab qhov zoo yog yooj yim los tswj.
Txheej txheem ntau lawm
- Extrusion tshuab moulding txoj kev: Cov khoom siv polymer yog rhuab mus rau lub xeev molten thiab extruded los ntawm extruder los ua ib tug tubular dawb paug. Tom qab ntawd, cov cua compressed yog tshuab mus rau hauv lub raj khoob kom nws nthuav thiab cling rau pwm kom txias thiab shaping. Thaum kawg, tus geomembrane du yog tau los ntawm kev txiav. Lub geomembrane tsim los ntawm txoj kev no muaj cov tuab tuab thiab cov khoom siv zoo.
- Txoj kev Calendering: Cov khoom siv polymer yog rhuab thiab tom qab ntawd extruded thiab ncab los ntawm ntau cov chais ntawm lub calender los ua ib zaj duab xis nrog ib qho tuab thiab dav. Tom qab txias, qhov du geomembrane tau txais. Cov txheej txheem no muaj kev ua haujlwm siab ntau lawm thiab cov khoom siv dav dav, tab sis cov thickness uniformity kuj tsis zoo.
Daim ntawv thov teb
- Kev txuag dej: Nws yog siv rau kev kho dej los tiv thaiv kev txuag dej xws li reservoirs, dams, thiab kwj dej. Nws tuaj yeem tiv thaiv dej kom zoo, txhim kho cov dej cia thiab kev ua haujlwm ntawm cov dej txuag dej, thiab txuas ntxiv lub neej kev pab cuam ntawm qhov project.
- Landfill: Raws li cov tshuaj tiv thaiv kab mob hauv qab thiab sab ntawm qhov pov tseg, nws tiv thaiv cov kua qaub los ntawm kev ua qias tuaj hauv av thiab dej hauv av thiab tiv thaiv ib puag ncig ecological ib puag ncig.
- Lub tsev tsis muaj dej: Nws yog siv los ua cov txheej txheem dej tsis zoo hauv lub ru tsev, hauv qab daus, chav dej thiab lwm qhov chaw ntawm lub tsev los tiv thaiv kev nkag mus ntawm cov dej nag, dej hauv av thiab lwm yam dej hauv lub tsev thiab txhim kho cov dej tsis zoo ntawm lub tsev.
- Artificial toj roob hauv pes: Nws yog siv los tiv thaiv cov dej ntws ntawm cov pas dej, cov pas dej toj roob hauv pes, golf course waterscapes, thiab lwm yam, kom muaj kev ruaj ntseg ntawm lub cev dej, txo cov dej ntws tawm, thiab muab lub hauv paus zoo rau kev tsim toj roob hauv pes.
Specifications thiab Technical Indicators
- Specifications: Lub thickness ntawm tus du geomembrane feem ntau yog nruab nrab ntawm 0.2mm thiab 3.0mm, thiab qhov dav yog feem ntau ntawm 1m thiab 8m, uas tuaj yeem kho raws li qhov xav tau ntawm cov haujlwm sib txawv.
- Kev ntsuas kev ntsuas: suav nrog lub zog tensile, elongation ntawm kev tawg, lub kaum sab xis tsim kua muag lub zog, hydrostatic siab tsis kam, thiab lwm yam. Lub zog tensile feem ntau yog nyob nruab nrab ntawm 5MPa thiab 30MPa, elongation ntawm tawg yog nruab nrab ntawm 300% thiab 1000%, lub kaum sab xis tsim kua muag Lub zog yog nruab nrab ntawm 50N / mm thiab 300N / mm, thiab hydrostatic siab tsis kam yog nruab nrab ntawm 0.5MPa thiab 3.0MPa
