Abstract
The utility model relates to an extrusion die head device of a geomembrane with rough surface, and a product of the device. The utility model is characterized in that a die head (1) is provided with at least two ring extrusion channels (2), wherein, at least one of the channels (2) is provided with at least a control head (3). The product of the device is provided with at least one rough surface, which can increase the roughness of the geomembrane surface and improve the binding degree of the geomembrane and the substances which are contacted with the geomembrane.
Description
Described technical field:
The utility model relates to the product of a kind of rough surface geomembrane extrusion die device and production thereof.
Background technology:
Geomembrane in the past (thick plastic foil) because its two sides is shiny surface, so friction is little in use and between the material of surface contact with it, therefore, is easy to generate relative slip between the two; For example: film is used in the river levee dykes and dams dam facing water proof, between smooth face and the levee slope face earth to contact friction little, the bank protection ability.
Technology contents:
In order to produce the big geomembrane of friction between the material a kind of and contact with it, the utility model provides: a kind of rough surface geomembrane extrusion die device, it is characterized in that: die head (1) has at least two annulars to extrude passage (2), wherein at least one runner (2) at least one control head (3) is housed.The effect of runner control head (3) is when needed, with place runner (2) partial closure, like this, the material of handling through foaming just can not pass through from the part of sealing, tool is closed and the material of handling without foaming just can diffuse in and account for from adjacent passage (2), smooth face of back formation extruded thereby there is the material of handling without foaming on the formation matsurface at intervals after extruding through the material of foaming processing in the former residing position of material of handling through foaming.The number of smooth the face that the number of the runner control head (3) that go up to be provided with in same circular passage (2) has between equaling to be shaped on the corresponding coarse surface layer of film in back, the width of smooth the face of width decision of runner control head (3) closed channel (2).Coarse surface layer has the effect of friction between the material that increase contacts with it; Smooth surface layer has the effect of the tensile property that guarantees film.Both are in conjunction with the combination property that just can improve film effectively.Certainly, runner control head (3) if closed flow (2) not, a surface that then can form film at least is matsurface completely.
The utility model said structure can be perfect like this:
In the runner (2) on film surface, runner (2C) can be housed.What extrude in the runner (2 C) is the material of handling without foaming, it will in the runner (2) on film surface, extrude in the middle of the material that foaming is handled, between go into the material of handling without foaming, thereby finally formation has had the not foamed strip face of enhancing film tensile strength, the matsurface of the film of the material formation of handling through foaming.
The rough surface geomembrane that rough surface geomembrane extrusion die device of the present utility model is produced is characterized in that: film is two layers or more at least simultaneously coarse multi-layer co-extruded geomembrane.This film can be two-layer co-extrusion, also can be multi-layer co-extruded; Its surface can be that single face is coarse, also can be two-sided all coarse;
In order to strengthen film tensile strength, go into smooth the face that the material handled without foaming forms between on the matsurface of film, the decline of the film tensile strength that the matsurface of the film of the material formation of handling to remedy because through foaming causes.

Embodiment:
Embodiment 1:
See Fig. 1, die head (1) has three annulars to extrude passage (2), between adjacent two runners (2), around runner (2), respectively be provided with one group of (totally 6) control head (3), wherein one group is located at the extruding on the passage (2) of film outer surface, and another group is located at extruding on the passage (2) of film inner surface.When control head (3) not during closed channel (2), the film of extruding is shown in Figure 4, (band hatching person is expressed as the plastics through foaming, is not expressed as plastics without foaming with the hatching person, below identical no longer repeat).When control head (3) closed channel (2), the film of extruding is shown in Figure 5.
Embodiment 2
See Fig. 2, Fig. 3 is equipped with runner (2C) in the runner (2) of film outer surface.Remaining is identical with embodiment 1.The product of device is to have had the not foamed strip face that strengthens film tensile strength, and the matsurface of the film that is formed by the material through the foaming processing is seen Fig. 6.
Claims (4)
1, a kind of rough surface geomembrane extrusion die device, it is characterized in that: die head (1) has at least two annulars to extrude passage (2), wherein at least one runner (2) at least one control head (3) is housed.
2, rough surface geomembrane extrusion die device according to claim 1 is characterized in that: runner (2C) is housed in the annular of film superficial layer is extruded passage (2).
3, the rough surface geomembrane of a kind of claim 1 or 2 described rough surface geomembrane extrusion die devices productions, it is characterized in that: film is two layers or more at least simultaneously coarse multi-layer co-extruded geomembrane.
4, rough surface geomembrane according to claim 3 is characterized in that: smooth face arranged between on the matsurface of film.
