1. Different anchorage structures
HDPE concrete protective liners, anchor solids cross each other in a planar distribution, providing multi-directional binding.
PVC sheet is a strip anchor solid, can only provide transverse force, longitudinal slip unlimited.
2. The strength and arrangement density of anchor solids are different
HDPE concrete protective liners, single anchor solid drawing force can reach 100kg, 420 per square meter can provide 42 tons of anchorage force.
The anchorage drawing force of PVC sheet material is only 14N/mm, about 15 pieces per square meter, which translates into about 21 tons of anchorage force per square meter.
3. Different materials
The tensile strength, elongation at break, impact resistance and abrasion resistance of PE materials are significantly higher than those of PVC.PVC is polar material, easy to adhere to other substances, PE is non-polar material, not easy to adhere to other substances.
