Vim li cas geotextile muaj xim txawv ntawm xim dub thiab dawb?
Txhua hom geotextile nws muaj nws tus yam ntxwv. Geotextiles yog siv rau hauv ntau cov ntawv thov, tab sis lawv tsis yog qhov dav dav hauv txhua daim teb.Piv txwv li, cov xim dub dua (carbon dub) lossis geotextile nrog rau kev tiv thaiv kev laus (tiv thaiv kab mob, lub teeb stabilizer, thiab lwm yam) ntxiv rau yuav tsum tau siv rau qhov tsis muaj kev tiv thaiv lossis thinner tiv thaiv txheej.Thaum thaj chaw uas nkag mus rau cov nroj tsuag xws li reeds yuav tsum tau nqus dej hauv qab daim nyias nyias thiab txhim kho kev ruaj ntseg ntawm cov txheej tiv thaiv, geotextiles yuav muab tso rau hauv qab geotextiles lossis HDPE geotextiles.
Txij li thaum muaj dub, yuav muaj dawb geotextiles. Nov yog qhia qhov luv luv ntawm qhov sib txawv ntawm ob:
1. Cov khoom siv sib txawv: dub geotextiles feem ntau yog HDPE (high ntom polyethylene) geotextiles, thiab dawb geotextiles yog feem ntau LDPE (tsis ntom polyethylene) geotextiles.Qhov ob qhov tseem ceeb yog qhov sib txawv hauv qhov ceev thiab kev ua tau zoo. Cov qub tau ntom ntau dua thiab qhov tom kawg muaj qhov qis dua. Cov qub feem ntau yog siv los ua cov khoom lag luam geotechnical engineering, thiab tom kawg yog siv los ua khoom yeeb yaj kiab.
2. Lub rooj sib txig sib txawv: qhov laj thawj vim li cas daim ntaub geotextile yog xim dub vim tias cov geotextile tau ntxiv nrog cov xim dub masterbatch thaum lub sijhawm tsim khoom. Cov pellet masterbatch no tau ntxiv rau cov txheej txheem ntau lawm ntau lawm geotextile. Feem ntau, ib qho me me Cov xim masterbatch tuaj yeem ua cov txheej txheem ntau ntawm cov khoom geotextiles, thiab cov khoom siv geotextile masterbatch tau yooj yim rau cov txheej txheem, thiab nws tsis cuam tshuam rau qhov zoo ntawm cov geotextile.
3. Txawv ntau qhov sib txawv: Vim tias qhov ceev ntawm HDPE dub geotextiles ntau dua qhov ntawm LDPE dawb geotextiles, ob lossis ob txoj siv yuav muaj qhov sib txawv. Zuag qhia tag nrho kev ua tau zoo yuav tsum tau muab coj los sib piv raws li kev siv ntawm ob qho tib qho ntawm kev tsim kho. Los sib piv (tsis txuas nrog). Ob qho yuav siv nyob rau hauv kev tsim kho sib txawv, thiab qee zaum lawv yuav hloov chaw rau lwm qhov.
4. Txawv ductility: dawb LDPE geotextile muaj ductility zoo dua li dub HDPE geotextile, thiab nws cov dag kom muaj zog dua dub HDPE geotextile. Dawb LDPE geotextile uas ua tau raws li cov qauv kev tsim qauv tshuab tseem yog lub cim tshiab ntawm cov khoom tiv thaiv geotechnical los tiv thaiv. Lub peev xwm kuj tseem muaj zog dua li cov dub HDPE geotextile nyob rau hauv tib txoj haujlwm, thiab tam sim no muaj ntau cov khoom kuj tuaj yeem pom cov khoom lag luam.
