Abstract

The invention discloses a double-layer water injection plastic film. According to the invention, by increasing the layer number, the anti-abrasion capability of the film is enhanced. At the same time, by adopting the water injection design for the middle part of the film, the thermal insulation capability is improved. By adopting the film provided by the invention, the agricultural greenhouse can have a better thermal insulation effect and the service lifetime of the greenhouse plastics can be prolonged.

Description

A kind of double-layer water injection plastic sheeting of agricultural greenhouse
Technical field
The present invention relates to double-plastic, in particular it relates to the double-layer water injection plastic sheeting of a kind of agricultural greenhouse.
Background technology
At present, the commonly used warmhouse booth of agricultural production, common booth is all single layer plastics films, though cheap, heat insulation effect is poor, it is frequently necessary to supplement heating measure in season in severe winter.Additionally the plastic sheeting of individual layer can only use a plant growing cycle, generally 1-2 month will be damaged, and booth it is frequently necessary to repair.
Summary of the invention
It is an object of the invention to, for the problems referred to above, propose the double-layer water injection plastic sheeting of a kind of agricultural greenhouse, to realize high insulating effect and durable advantage.
For achieving the above object, the technical solution used in the present invention is: the double-plastic of a kind of agricultural greenhouse, including plastic sheeting outside two-layer, connect with articulamentum plastics between double-layer films, connected mode for building up " it " shape by articulamentum plastic folding, burst is staggered with two two external films successively to be connected, identical with the plastic sheeting folded length being connected outside two, outer bilayer plastic sheeting and intermediate connecting layer film form triangular prism and adjoin each other, water is injected in the triangular prism space that each plastic layer is formed, this three-layer thin-film is suppressed adhesion every fixed range by the vertical direction along above-mentioned triangular prism rib.
Technical scheme has the advantages that
The double-plastic of the agricultural greenhouse of various embodiments of the present invention, owing to including double-plastic, uses the plastics of identical material to do supporting construction, can increase warming effect, strengthen antiwear property simultaneously between two-layer;Such that it is able to overcome the defect that in prior art, poor thermal insulation property is easily damaged, to realize increasing insulating efficiency, the advantage increasing service life.
Below by drawings and Examples, technical scheme is described in further detail.
Accompanying drawing explanation
Fig. 1 is the double-plastic schematic cross-section described in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention.
The present invention is the double-plastic of a kind of agricultural greenhouse, including plastic sheeting outside two-layer, connect with articulamentum plastics between double-layer films, connected mode for building up " it " shape by articulamentum plastic folding, burst is staggered with two two external films successively to be connected, identical with the plastic sheeting folded length being connected outside two, outer bilayer plastic sheeting is connected film with centre and forms the triangular prism adjoined each other, injecting water in the triangular prism space that each plastic layer is formed, this three-layer thin-film is suppressed adhesion every fixed range by the vertical direction along above-mentioned triangular prism rib.
For clear interpretation above-mentioned double-layer films rock-steady structure, refer to Fig. 1, Fig. 1 is the cross section of the mode connected between a kind of embodiment two-layer, double-plastic of the present invention can for but be not limited to situation shown in Fig. 1, in cross section, BLU is triangle, the plastics and two superficial layers that use same material the most between the two layers connect formation certain angle, the rock-steady structure utilizing triangle strengthens supportive, under this kind of connected mode, the connecting line that inside and outside two layers of plastic is connected plastics with centre is straight line parallel to each other.
Further, air it is full of in interlayer, when making film be in complete extended position, in interlayer, articulamentum plastics are 45 degree with the angle of outer surface, i.e. referring to the drawings 1, on this film cross section, each triangle base angle is 45 degree, structure is the most stable, the parallel lines distance 5 millimeters to 8 millimeters that homonymy junction is formed, and this film portability and heat-insulating property can reach preferably balance.During industrial production, for satisfied different requirements, typically cross section intermediate cam shape base angle is set between 38 degree to 52 degree.
Further, this bilayer film is suppressed adhesion every fixed range by the vertical direction along above-mentioned connecting line, can increase durability, spacing distance be 5 millimeters to 8 millimeters optimal.
In sum, use three-layer plastic, on the basis of existing common agricultural greenhouse plastics, is set to double-decker by the present invention, strengthens heat-insulating property and detrimental resistance.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention, although the present invention being described in detail with reference to previous embodiment, for a person skilled in the art, technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
