Dab tsi yog Npuag-Needle Punch Geotextile

Staple fiber ntaukoob punched geotextileyog ib hom non-woven fabrics feem ntau yog siv nyob rau hauv industrial thiab kev tsim kho cheeb tsam.Cov khoom siv tuaj yeem yog polyproplene thiab polyester.Cov fibers yog crimped staple nrog ib tug fineness ntawm 6-12 denier thiab ib tug ntev ntawm 54-64 hli.Nws dhau los ua daim ntaub los ntawm kev tsim cov txheej txheem ntawm kev qhib, carding, messing (interwind luv fibers ua ke nrog ib leeg), nteg (tus qauv entanglement thiab kho), thiab koob punching ntawm cov khoom siv tsis-woven.

Koob punch geotextile muaj covpeculiarity ntawm zoo huab cua permeability, dej permeability.Yog li nws tuaj yeem siv los ua kom cov dej ntws los ntawm, vim li ntawd, nws muaj txiaj ntsig kom tsis txhob cuam tshuam cov xuab zeb poob.Vim tias muaj dej zoo conductivity, koob punch geotextile tuaj yeem tso cov dej ntws ruaj khov rau hauv cov av / xuab zeb, thiab tso tawm cov kua thiab roj ntau dhau hauv cov qauv av.

Hauv qab kev pab ntawmgeotextile, peb tuaj yeem txhim kho lub zog tensile thiab tiv thaiv deformation muaj peev xwm ntawm cov av.Peb tuaj yeem txhim kho kev ruaj ntseg ntawm lub tsev qauv thiab tseem txhim kho cov av zoo.

Thaum koob punch geotextile siv rau hauv cheeb tsam tsim kho, nws tuaj yeem pab tiv thaiv kev sib xyaw ntawm cov xuab zeb, av thiab pob zeb.Raws li rab koob punch geotextile muaj cov yam ntxwv ntawm cov dej permeability siab, txawm tias nyob rau hauv lub siab ntawm cov av thiab dej, nws tseem tuaj yeem tswj cov dej permeability zoo heev.

Feem ntau cov khoom siv ntawm rab koob punch geotextile yog polypropylene thiab polyester, lawv yog cov tshuaj fibers muaj lub luag haujlwm hauv acid thiab alkali tsis kam, tsis muaj corrosion, tsis muaj npauj noj, los tiv thaiv oxidation.Qhov no haum rau ntau thaj chaw muaj kev lag luam thiab nws ua haujlwm.

Nyob rau hauv kev pom ntawm daim ntawv thov dav ntawm koob punch geotextile, lawv yog cov neeg nyiam heev thiab cov muag kub ob qho tib si hauv kev lag luam hauv tsev thiab txawv teb chaws.Yog li ntawd's tsis muaj doult tias nws kuj tau ua ib qho kev pab loj heev rau kev nce qib ntawm kev lag luam thiab kev loj hlob ntawm tib neeg.
