Av nplaum Geosynthetic Barriers
Product Description
Peb, Shanghai Yingfan Engineering Material Co., Ltd., yog cov av nplaum geosynthetic barriers chaw tsim tshuaj paus nyob rau hauv Suav teb. Cov khoom no tseem hu ua "geosynthetic av nplaum liner" (GCL), "pam av", "bentonite pam", "bentonite mats", "prefabricated bentonite av nplaum pam" thiab "av nplaum geosynthetic barriers", tom kawg tam sim no nyiam los ntawm International Organization rau Standardization (ISO).
Av nplaum Geosynthetic Barriers Taw Qhia
Nws yog bentonite geo-synthetic waterproofing barrier uas feem ntau hloov cov khaubncaws sab nraud povtseg ntawm kim compacted av nplaum.
Nws yog qhaub cij-ua los ntawm cov tsis-woven geotextile, ib tug ntuj sodic bentonite txheej thiab ib tug polypropylene woven daim ntawv.
Vim muaj cov yam ntxwv ntawm hydro-expansive ntawm bentonite (Bentonite muaj feem ntau (> 70%) ntawm montmorillonite los yog lwm yam expansive clays) thiab rab koob xuas nrig ntaus txoj kev tsim khoom uas muab cov khoom sib xyaw ua ke shear lub zog, qhov tseem ceeb rau kev teeb tsa ntawm qhov chaw siab tshaj, peb av nplaum geosynthetic teeb meem yuav siv tau nyob rau hauv ntau erosion tswj thov civil engineering.
Nws qhov kev ua tau zoo tuaj yeem ua tau raws lossis tshaj GRI-GCL3 thiab peb lub teb chaws tus qauv JG / T193-2006.
