Abstract

The invention relates to a geomembrane, particularly to a smooth geomembrane. The smooth geomembrane comprises a substrate layer; an impermeable layer is arranged under the substrate layer; a reinforcement layer is arranged on the upper surface of the substrate layer. According to the smooth geomembrane, the multilayer structure is made of different materials, every layer has different physical and chemical performances, and the intensity of the smooth geomembrane can be effectively improved.

Description

Light face geomembrane
Technical field
The present invention relates to a kind of geomembrane, be specially a kind of light face geomembrane.
Background technology
Traditional light face geomembrane, only has one deck geomembrane body composition, and body adopts commaterial to make, and its intensity can not get ensureing.
Summary of the invention
For above-mentioned technical problem, the invention provides the light face geomembrane that a kind of intensity is high, concrete technical scheme is:
Light face geomembrane, comprises substrate layer, and substrate layer soffit has impervious barrier, and substrate layer upper surface has enhancement Layer.
Described substrate layer uses ethylene-vinyl acetate copolymer (EVA) to make, impervious barrier is made up of high density polyethylene (HDPE) (HDPE) or linear low density polyethylene (LLDPE) (LLDPE), enhancement Layer is that metallocene PE (m-LLDPE) is made, and the raw material of every layer utilizes seamless fusion joining process to fit together under molten condition.
Substrate layer, impervious barrier and enhancement Layer, the thickness proportion of every layer as requested, can be adjusted in 5%～80% scope.
Sandwich construction of the present invention adopts different materials to make, and every layer is embodied different different physics, chemical property, can effectively improve light face geotechnique film strength.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Accompanying drawings the specific embodiment of the present invention, as shown in Figure 1,
Light face geomembrane, comprise substrate layer 1, substrate layer 1 uses ethylene-vinyl acetate copolymer (EVA) to make, substrate layer 1 soffit has impervious barrier 3, impervious barrier 3 is made up of high density polyethylene (HDPE) (HDPE), substrate layer 1 upper surface has enhancement Layer 2, and enhancement Layer 2 is made for metallocene PE (m-LLDPE).The raw material of every layer utilizes seamless fusion joining process to fit together under molten condition.
In the situation that requirement of strength is high, impervious barrier 3 is made up of linear low density polyethylene (LLDPE) (LLDPE).
