Abstract
The utility model discloses a novel three-layer geomembrane, and is characterized by including a first defending layer, a second defending layer and a third defending layer, wherein the first defending layer and the second defending layer are sequentially combined with the third defending layer together; the thickness of the first defending layer is 0.4-2.0 mm; the thickness of the second defending layer is 0.1-0.3 mm; the thickness of third defending layer is 0.4-2.0 mm; the first defending layer and the third defending layer are made of high density polyethylene; and the second defending layer is made of linear low density polyethylene. The geomembrane adopts three layers of defending layers; the outermost layer and the innermost layer are made of high density polyethylene; the intermediate layer is made of linear low density polyethylene; the geomembrane has stronger chemical resistance and percolation resistance, can more efficiently prevent noxious substances, such as chemical substances from permeating, and has telescopic flexibility, constant tension load stress cracking resistance, and elasticity brought by the linear low density polyethylene.
Description
Technical field
The utility model relates to a kind of geomembrane.
Background technology
The application of geomembrane is comparatively extensive, such as antiseepage waterproofing works such as refuse landfill, tunnel, water channel, reservoir, treatment tank, cesspools.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 or double-deck 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 impervious barrier the crack occur, and then it is damaged to cause geomembrane to occur, and shortened the service life of geomembrane.
By as seen above-mentioned, be necessary above-mentioned geomembrane is improved.
The utility model content
Task of the present utility model is to solve the technological deficiency that geomembrane of the prior art exists, and a kind of novel three layers of geomembrane are provided.
Its technical solution is:
A kind of novel three layers of geomembrane are made up of first impervious barrier, second impervious barrier and the 3rd impervious barrier, and first impervious barrier, second impervious barrier and the 3rd impervious barrier combine successively; Wherein, the thickness of above-mentioned first impervious barrier is 0.4～2.0mm, the thickness of second impervious barrier is 0.1～0.3mm, the thickness of second impervious barrier is 0.4～2.0mm, above-mentioned the first, the 3rd 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 1.0mm, and the thickness of second impervious barrier is 0.2mm, and the thickness of the 3rd impervious barrier is 1.0mm.
Above-mentioned first impervious barrier, second impervious barrier and the 3rd 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 three layers of impervious barrier, outermost layer wherein and innermost layer adopt high density polyethylene (HDPE) to make, the intermediate layer then adopts LLDPE to make, when having stronger chemical resistance and impervious filter, more effectively stoping the infiltration of nuisances such as chemical substance, have flexible pliability, anti-constant stretch bearing strength test cracking behavior and flexibility that LLDPE brings again.
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, have longer service life.
Description of drawings
Below in conjunction with accompanying drawing and the specific embodiment the utility model is done further explanation:
Fig. 1 is the structural principle schematic diagram of a kind of embodiment of the present utility model, is its section structure.
The specific embodiment
In conjunction with Fig. 1, a kind of novel three layers of geomembrane are made up of first impervious barrier 1, second impervious barrier 2 and the 3rd impervious barrier 3.Above-mentioned first impervious barrier is in skin (the superiors), adopts high density polyethylene (HDPE) (HDPE) to make, and is added with black masterbatch, forms black layer; Second impervious barrier 2 layer that mediates adopts LLDPE (LHDPE) to make, and also can add black masterbatch or its allochromatic colour mother; The 3rd impervious barrier 3 is in internal layer (orlop), adopts high density polyethylene (HDPE) to make, and also can add black masterbatch or its allochromatic colour mother.Above-mentioned first impervious barrier, second impervious barrier and the 3rd impervious barrier adopt plastic processing, make the three together as preferred co-extrusion processing technology wherein.The thickness of above-mentioned first impervious barrier is 0.4～2.0mm, and the thickness of second impervious barrier is 0.1～0.3mm, and the thickness of second impervious barrier is 0.4～2.0mm.Preferably, the thickness of above-mentioned first impervious barrier is 1.0mm, and the thickness of second impervious barrier is 0.3mm, and the thickness of the 3rd impervious barrier is 1.0mm.
Above-specified high density polyethylene (HDPE), and LLDPE (LHDPE) can be the commercially available prod.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this specification, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within protection domain of the present utility model.
Claims (3)
1. novel three layers of geomembrane is characterized in that being made up of first impervious barrier, second impervious barrier and the 3rd impervious barrier, and first impervious barrier, second impervious barrier and the 3rd impervious barrier combine successively; Wherein, the thickness of above-mentioned first impervious barrier is 0.4～2.0mm, the thickness of second impervious barrier is 0.1～0.3mm, the thickness of second impervious barrier is 0.4～2.0mm, above-mentioned the first, the 3rd impervious barrier adopts high density polyethylene (HDPE) to make, and second impervious barrier adopts LLDPE to make.
