Non woven Geotextile

الوصف

The geotextile is made of polypropylene staple fibers on cross-laying equipment and needle punched equipment. Feature: It owns the advantages of acid and alkali resistance, erosion resistance, aging resistance, large strength, stable size, good filtrability etc. Functions: It mainly applied in water conservancy, road and railway for strengthening, separation, reversed filter and drainage of projects Testing index g/sqm **0 **0 **0 **0 **0 **0 **0 **0 **0 **0 **0 Note Mass error in unit area % *8 *8 *8 *8 *7 *7 *7 *7 *6 *6 *6 　　　 Thickness .mm.≥ 0.9 1.3 1.7 2.1 2.4 2.7 3.0 3.3 3.6 4.1 5.0 　 Error of width .% *0.5 Tensile strength at break KN/m≥ 2.5 4.5 6.5 8.0 9.5 *1.0 *2.5 *4.0 *6.0 *9.0 *5.0 Length and width Elongation at break≤(%) *****0 CBR puncture resistance KN≥ 0.3 0.6 0.9 1.2 1.5 1.8 2.1 2.4 2.7 3.2 4.0 　 Pore size **0（**5）mm 0.***0.2 　 Vertical permeability coefficient cm/s Kx(********3) K＝1.**9.9 Tearing strength KN≥ 0.*8 0.*2 0.*6 0.*0 0.*4 0.*8 0.*3 0.*8 0.*2 0.*6 0.*0 Length and width a
