Abstract
The utility model discloses a novel geomembrane which is characterized by consisting of a first seepage-proof layer and a second seepage-proof layer, and the first seepage-proof layer is combined with the second seepage-proof layer; and the first seepage-proof layer and the second seepage-proof layer are made from the high-density polyethylene. The novel geomembrane adopts the two seepage-proof layers which are combined with each other by a co-extrusion processing technology and are made from the high-density polyethylene, thereby being higher in the chemical corrosion resistance and the infiltration resistance, and being capable of effectively avoiding the seepage of harmful substances such as chemical substances and the like; and a test shows that the second seepage-proof layer which is made from the high-density polyethylene is hardly penetrated by a crack induced stress, so that the novel geomembrane is longer in service life.
Description
Technical field
The utility model relates to geomembrane, particularly a kind of double-deck 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 novel geomembrane is provided.
Its technical solution is:
A kind of novel 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 also adopts high density polyethylene (HDPE) 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 is taked two-layer impervious barrier, combines in the mode of co-extrusion processing technology, and all adopts high density polyethylene (HDPE) to make, and has stronger chemical resistance and impervious filter, can more effectively stop the infiltration of nuisances such as chemical substance.
2, the utility model shows after tested, and crack-induced stress neither be easy to penetrate second impervious barrier that adopts high density polyethylene (HDPE) to make, and has long application life.
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 novel 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, also adopts high density polyethylene (HDPE) to make, and also can add black masterbatch or its allochromatic colour mother.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)
