Needle-punched geotextile yog cov khoom siv tshwj xeeb uas sib txuas nrog tus nqi qis tib lub sijhawm nrog cov khoom tshwj xeeb. Nws muaj qhov dav dua li lwm yam ntawm cov khoom siv no vim tias nws yog tus nqi ntau dua rau ntau qhov haujlwm. Lub hauv paus uas tsis yog-woven yog tsim los ntawm cov txheej txheem koob-punched los ntawm polymer monofilaments, uas tau muab faib ua ob hom: polyester thiab polyamide.

Ntawm cov kev xaiv rau geosynthetics, tsis-woven thiab woven xaiv yog feem ntau. Cov tom kawg muaj cov qib siab ntawm elasticity, txaus lub zog thiab ib homogeneous qauv, thaum lawv tsis muaj dej permeability zoo. Cov khoom siv no tsim nyog rau kev tiv thaiv, kev sib cais ntawm cov khaubncaws sab nraud povtseg thiab ntxiv dag zog.
Non-woven geotextile yog ib yam khoom ua los ntawm cov xov los yog fibers, uas yog fastened ua ke los ntawm ib tug chaotic weave, nyob ntawm seb tus txheej txheem ntawm ntxiv dag zog.
Cov khoom siv Calendered yog tsim los ntawm kev koom nrog cov filaments tas li nyob rau hauv qhov kub thiab txias. Qhov kev xaiv kev tsim khoom no txo qhov yuav tshwm simtawg thaum lub sijhawm ua haujlwm, ua kom cov dej tsis zoo thiab lub zog muaj zog. Cov khoom zoo li no yog tus yam ntxwv ntawm homogeneous qauv nrog siab elongation thiab qib siab elasticity.
Nyob zoo
koob-punched geotextile, ntxiv rau cov khoom uas muab kev siv yooj yim, muaj cov npe ntawm cov txiaj ntsig pom tseeb:
- Cov khoom siv dej ua haujlwm tau zoo dua li lwm hom tsim los ntawm kev sib txuas nrog thermal.
- Durability thiab ntseeg tau. Cov hom zoo sib xws muaj cov khoom qis dua, txij li cov khoom organic uas muaj nyob rau hauv qhov muaj pes tsawg leeg raug cuam tshuam rau sab nraud yam tsis zoo thiab tuaj yeem raug rhuav tshem hauv ob peb xyoos.
- Needle-punched geotextile tsis nqus dej noo txhua, uas cov organic version tsis tuaj yeem khav ntawm.
- Muaj peev xwm ntawm bandwidth. Cov khoom zoo li no hla dej hauv ntau qhov kev taw qhia tib lub sijhawm, ua tsaug rau qhov uas nws tiv nrog nws cov ntim tseem ceeb.
- Ua raws li lub sijhawm ua haujlwm machining.
- Tsis nyiam nas.
- Txoj kev tiv thaiv rau kev puas tsuaj sab nraud (cov kab mob, kev hloov pauv kub, hluav taws xob ultraviolet, dampness).
- Yooj yim thiab yooj yim installation.
Yuav siv li cas
Rau kev nkag siab zoo ntawm qhov muaj peev xwm, nws tsim nyog xav txog ob lub hom phiaj tib lub sijhawm: los ntawm thaj chaw siv thiab daim ntawv thov tseem ceeb.
koob-punched daim ntaub pom nws daim ntawv thov hauv qab no:
- Txoj dej kom zoo tshem tawm cov dej noo ntau dhau los ntawm ntau hom.
- Kev sib cais ntawm cov av nyob ib sab. Ib qho piv txwv yog kev sib cais ntawm cov xuab zeb los ntawm txheej fertile kom tsis txhob sib tov thiab tom qab ntxuav tawm.
- Tiv thaiv cov khoom degradation kom nce lub sijhawm zoo.
- Kev lim dej thiab sib cais sib cais ntawm cov khoom me me.
- Av stabilization tiv thaiv av nkos nyob rau hauv cov cheeb tsam uas raug rau lawv.
thaj chaw thov
siv tseem ceeb suav nrog:
- creating tunnel passages;
- tso kev loj thiab kev tsheb ciav hlau;
- siv cov haujlwm ntsig txog kev tsim toj roob hauv pes;
- muab cov kav dej rau txhua lub hom phiaj;
- kho tau zoo ntawm kev tiv thaiv kev tiv thaiv embankments thiab nqes hav;
- creating landfills rau recycling;
- txhim kho cov qauv hydraulic (kwj dej, cov pas dej dag);
- txhim kho cov ntsiab lus;
- kev tsim vaj tsev nyob.
Cov npe saum toj no tsuas yog suav nrog qhov tseem ceeb ntawm daim ntawv thov, muaj ntau yam ntxiv.
Geotextile koob-punched: ntau lawm
Kev tsim lub hauv paus yog kauj ruam tseem ceeb. Txhim kho cov xov muaj zog yog tom qab rub los ntawm nws, tsim ib lub canvas ruaj khov nrog cov qauv uas tsis yog qauv. Cov txheej txheem thev naus laus zis tau ua tiavnyob rau ntawm ib tug tshwj xeeb tsim koob-punching tshuab. Nws muaj serrated ntse koob, vim hais tias txoj kev no tau txais xws li lub npe. Cov txheej txheem tsim khoom siv ntau yam khoom siv thiab sijhawm, ua tsaug rau qhov no, tsim tus nqi muag khoom qis.
Ntse
koob-punched geotextile, tus nqi ntawm nws txawv ntawm 17 txog 59 rubles ib square meter, muaj ntau yam kev siv. Ua ntej xaiv, nws tsim nyog txiav txim siab ntawm lub hom phiaj, thiab nyob ntawm qhov no, xaiv cov khoom siv nrog cov yam ntxwv xav tau, nyob ntawm qhov tsis muaj. Kev xaiv kom raug yuav ua rau koj siv tau zoo dua, txuas ntxiv lub sijhawm ua haujlwm thiab txo cov nqi nyiaj txiag.
Lub ntsiab parameter yog hom puag siv hauv kev tsim khoom. Qhov dav tshaj plaws yog polypropylene thiab polyamide. Lawv muaj cov yam ntxwv zoo sib xws ntawm lub zog, durability thiab kev ntseeg tau. Cov tom kawg tau lees paub los ntawm qhov tsis muaj cov khoom siv organic uas lwj sai sai.
Lub zog tensile qhia txog qib ntawm kev xa khoom thauj yam tsis tau poob ntawm cov neeg siv khoom thiab cov khoom siv. Non-woven geotextile nrog lub zog siab tshaj plaws yog siv rau hauv kev ruaj ntseg txoj kev slopes thiab embankments.
Qhov ntom rau cov khoom siv qhia tias nws cov tuab thiab ntau npaum li cov polymer nws muaj. Raws li qhov ntsuas no nce, kev ntseeg tau thiab kev ua tau zoo nce.
Cov elongation tsis yog qhia raws li feem pua. Muaj kev nthuav davtus nqi. Tab sis nws tsis yog ib txwm muaj txiaj ntsig los siv cov khoom siv nrog qhov tseem ceeb elongation, piv txwv li, thaum ua haujlwm los tiv thaiv cov av tawm. Tsis tas li ntawd, qhov transverse thiab longitudinal qhov tseem ceeb yuav txawv, qhov no kuj yuav tsum tau coj mus rau hauv tus account thaum tso.
Lub pore txoj kab uas hla yog qhia hauv micrometers. Cov cuab yeej no tseem ceeb tshwj xeeb hauv cov dej ntws, thiab hom av thiab cov ntsiab lus noo noo yuav tsum raug coj mus rau hauv tus account.
Cov ntsuas tsis pom muaj qhov cuam tshuam ntawm cov khoom siv. Feem ntau, koob-punched ntaub yog tus cwj pwm los ntawm cov coefficient siab.
Tsis siv tus qauv
Geotextile koob-punched "TechnoNIKOL" tsis ntev los no tau pom nws daim ntawv thov hauv horticulture. Nws yog ib qho tsim nyog sau cia tias, vim yog thaj chaw dav siv, nws dhau los ua qhov kev xaiv tsim nyog rau kev tiv thaiv cog ob lub caij ntuj sov thiab lub caij ntuj no. Nws muaj peev xwm tiv thaiv los ntawm scorching lub hnub, tiv thaiv ntau dhau evaporation ntawm noo noo, nrog rau los ntawm qhov kub tsis zoo. Cov khoom siv tsis dhau los ua qhov cuam tshuam rau kev sib pauv huab cua, tsis saturated nrog dej, vim nws tsis khov thiab khaws nws cov yam ntxwv qub.
Nyob rau hauv lub luag haujlwm ntawm mulching hluavtaws puag, koob-punched geotextile 300 g m2 kuj siv. Ib qho laj thawj ntxiv rau kev yuav nws yog qhov tseeb tias nws tiv thaiv kev loj hlob ntxiv ntawm cov nroj tsuag, thiab thaum tsim cov txheej txheem ntxiv ntawm cov av, cov khoom siv yuav ua raws li cov txheej txheem sib cais uas tiv thaiv kev sib xyaw.
Rationaldaim ntawv thov nyob rau hauv cov nqe lus ntawm kev pab lub neej ntev. Tsis tas li ntawd, nyob rau hauv rooj plaub thaum lub hauv paus system ntawm cov ntoo pib loj hlob nyob rau hauv tag nrho cov kev taw qhia thiab rhuav tshem lub siab ncaj ncees ntawm cov av, nws yog ib qhov ua tau kom txwv tsis pub kev loj hlob thaum npaj lub site. Ua li no, cov ntaub ntawv tau muab tso rau hauv cov av, uas tiv thaiv kev loj hlob kab rov tav.
Kub-kho geotextiles tau txais kev nyiam ntawm cov neeg tsim qauv toj roob hauv pes. Nrog nws cov kev pab, nws muaj peev xwm tsim ntau txoj kev, paj txaj ntawm cov duab tsis zoo, cov khoom zoo nkauj.
Zaj lus
Cov khoom siv no kuj pheej yig nrog kev ua haujlwm dav, nws tau dhau los ua dav thiab muaj cov khoom tshwj xeeb. Raws li txoj cai, xws li geotextiles ua haujlwm zoo heev ntawm lawv lub hom phiaj, qhia txog lawv cov kev ua tau zoo thiab qhov tsis zoo ntawm lwm cov ntaub ntawv.
