Guilin HDPE biogas digester impervious geomembrane

  The deformation of one cloth and one film can transfer and disperse the stress caused by the concave convex defect of the bottom cushion quickly, and the strain capacity is strong
Geotextile is used instead of particle material as the protective layer of geomembrane to protect the geomembrane impervious layer from damage, reduce the matching requirements of cushion particle size, and play the role of drainage
The friction coefficient is large, which can prevent the slip of the covering layer
It has a larger friction coefficient than HDPE film and non-woven fabric in composite geomembrane
Composite geomembrane can increase the slope ratio and reduce the floor area
Tearing, bursting and puncture have high mechanical strength
Some thermal insulation can reduce the damage of soil frost heaving to geomembrane, so as to reduce soil deformation
The use of embedded paving has excellent anti-aging properties and reduces engineering maintenance
The laying construction is simple, reduces the transportation volume, reduces the project cost and shortens the construction period
As a floor covering material, grass proof cloth (Gardening cloth) has the advantages of good air permeability, fast water seepage, anti weed growth, preventing plant roots from drilling into the ground and affecting crop growth
At the same time, gardening cloth (grass proof cloth) has the characteristics of soil moisture conservation and moisture retention
When used in arid areas, it can reduce the investment cost of water conservancy irrigation by 30% and beautify the planting environment, It can effectively replace herbicides and other pesticides, weed and pest control, and improve labor productivity and economic benefits
