Abstract
The utility model discloses a geomembrane, which is characterized by comprising a first seepage-proofing layer and a second seepage-proofing layer, wherein the first seepage-proofing layer and the second seepage-proofing layer are bonded together, the first seepage-proofing layer is made of high-density polyethylene and the second seepage-proofing layer is made of linear low-density polyethylene. The geomembrane provided by the utility model not only has chemical corrosion resistance and seepage resistance, which are brought by the high-density polyethylene, and can be used for effectively inhibiting the seepage of chemical substances and other harmful substances, but also has flexible suppleness, constant-tensile-load stress crack resistance and flexibility, which are brought by the linear low-density polyethylene.
Description
Technical field
The utility model relates to geomembrane, particularly a kind of double deck type geomembrane.
Background technology
Along with the development of the world today, geomembrane is widely used in seepage control projects such as refuse landfill, mining site, water conservancy projects, biomass pool.What cause its damaged so that seepage phenomenon owing to reasons such as the puncture of engineering explosion, sharp-pointed object and scuffings in geomembrane construction or use is inevitable.Existing geomembrane is mainly taked the technical approach of individual layer impervious barrier, is made by high density polyethylene (HDPE).The geomembrane of above-mentioned technical approach is in construction or use, and crack-induced stress easily makes the individual layer impervious barrier crack occur, and then it is damaged to cause geomembrane to occur, and shortened the application life of geomembrane.
The utility model content
Task of the present utility model is to solve the existing above-mentioned technological deficiency of prior art geomembrane, and a kind of geomembrane is provided.
Its technical solution is:
A kind of geomembrane is made up of first impervious barrier and second impervious barrier, and first impervious barrier and second impervious barrier combine; Wherein, first impervious barrier adopts high density polyethylene (HDPE) to make, and second impervious barrier adopts LLDPE to make.
The thickness of above-mentioned first impervious barrier is 0.1～0.5mm, and the thickness of second impervious barrier is 0.4～2.0mm.
The thickness of above-mentioned first impervious barrier is 0.5mm, and the thickness of second impervious barrier is 0.5mm.
Above-mentioned first impervious barrier and second impervious barrier are to take the mode of co-extrusion processing technology to combine.
The utlity model has following useful technique effect:
1, the utility model chemical resistance and impervious filter of both having had high density polyethylene (HDPE) and being brought, can stop the infiltration of nuisances such as chemical substance effectively, the flexible pliability of being brought that has LLDPE again, anti-constant stretch bearing strength test cracking behavior and flexibility.
2, the utility model shows after tested, and crack-induced stress can not penetrate second impervious barrier that adopts low density polyethylene (LDPE) to make.Under the situation of the utility model geomembrane at constant stretch bearing strength test cracking, when the first impervious barrier crack of being made by high density polyethylene (HDPE) runs into second impervious barrier, the crack expansion will stop, and can stop the stress cracking of geomembrane effectively.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
Figure is the structural principle schematic diagram of a kind of embodiment of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of geomembrane is made up of first impervious barrier 1 and second impervious barrier 2.First impervious barrier 1 is in skin, adopts high density polyethylene (HDPE) to make, and is added with black masterbatch, forms black layer.Second impervious barrier 2 is in internal layer, adopts LLDPE to make, and also can add black masterbatch or other look mother, forms corresponding chromatograph.Above-mentioned first impervious barrier and second impervious barrier adopt plastic processing, as preferred co-extrusion processing technology wherein both are combined.The thickness of above-mentioned first impervious barrier is preferably 0.5mm, and the thickness of second impervious barrier is preferably 0.5mm.
The technology contents of not addressing in above-mentioned each mode is taked or is used for reference prior art and can realize.
Need to prove, any equivalent way that those skilled in the art made under the instruction of this manual, or obviously variant all should be in protection domain of the present utility model.
Claims (4)
