Product introduction:
Plastic blind ditch, also known as underground drain, culverts, etc., it is heated to melt thermoplastic synthetic resin through the nozzle after the extrusion of filaments superimposed together, and weld-phase point from the three-dimensional porous materials. Products have circular and rectangular cross-section and so on. And in accordance with customer requirements in different formulations of production high temperature, flame retardant, resistant to strong acid-base, high elasticity, high hardness, etc. Products with different characteristics.
Characteristics:
Plastic blind ditch itself is much the same toughness of modified plastic wire melting root knot formed, there is no pressure was off, the possibility of damage. 250kpa under the pressure of sectional porosity remains at 60%, even greater pressure to impose, there is always the water gap, there are still 10-15% of the porosity, and good recovery.
Plastic blind ditch the surface of the average opening rate of 90-95%, far higher than other similar products. Can be the most effective collection of water seepage in the soil and drain away pooling timely.
Plastic blind ditch from corrosion-resistant fiber made of polyethylene membrane and modified three-dimensional mesh portfolio, are in soil, degradation of the merits of the water will never be anti-aging formula, can maintain a permanent material change of characteristics.
Plastic blind ditch the membrane according to different soil to choose, and fully meet the demand, and avoid the old single membrane Product disadvantage.
Plastic blind ditch the proportion of light, on-site construction and installation is very convenient, greatly accelerate the construction efficiency.
