Yas tiaj tiaj woven geotextile
Woven geotextile yog cov khoom siv geosynthetic woven los ntawm polypropylene thiab polypropylene ethylene daim kab xev ua raw khoom.Nws yog dav siv hauv geotechnical engineering xws li kev txuag dej, hluav taws xob fais fab, chaw nres nkoj, txoj kev loj thiab kev tsim kho tsheb ciav hlau.
1. Lub zog muaj zog Vim yog siv cov yas tiaj tus hlau, nws tuaj yeem tuav lub zog txaus thiab elongation nyob rau hauv qhuav thiab ntub dej.
2. Corrosion resistance Nws tuaj yeem tiv taus corrosion rau lub sijhawm ntev hauv av thiab dej nrog pH sib txawv.
3. Cov dej zoo permeability Muaj qhov sib txawv ntawm cov xov hlau tiaj tus, yog li nws muaj dej permeability zoo.
4. Cov khoom zoo tiv thaiv kab mob, tsis muaj kev puas tsuaj rau cov kab mob thiab npauj.
5. Kev tsim kho yooj yim Vim tias cov khoom siv yog lub teeb thiab mos, nws yooj yim rau kev thauj mus los, tso thiab kev tsim kho.
