Abstract

The invention discloses a three-layer plastic film for an agricultural greenhouse. According to the three-layer plastic film, the wear resistance of the film is improved by increasing the number of layers, the heat-retaining capacity of the film is improved due to the hollow design, the agricultural greenhouse can have a better heat-retaining effect, and the service life of the greenhouse is prolonged. Besides, if the plastic on the outer layer is broken or has poor light receiving efficiency in the use process, the plastic film on the outer layer can be scraped off or can be taken off and turned over for use.

Description

A kind of three-layer plastic thin film of agricultural greenhouse
Technical field
The present invention relates to double-plastic, in particular it relates to the three-layer plastic thin film 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 monolayer 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 three-layer plastic thin film 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 three-layer plastic thin film of a kind of agricultural greenhouse, including the outside plastic sheeting that two-layer is parallel, an intermediate layer being parallel to outer layer is also had between double-layer films, have the most respectively between intermediate layer with two outer layers and be connected plastic layer, in order to connect intermediate layer and two outer layer plastics, connected mode for building up " it " shape by articulamentum plastic folding, burst is staggered with intermediate layer and outer membrane successively to be connected, each section of folded length of articulamentum plastics is equal, outer bilayer plastic sheeting, intermediate layer plastics and two articulamentum thin film form triangular prism and adjoin each other.
Technical scheme has the advantages that
The three-layer plastic thin film of the agricultural greenhouse of various embodiments of the present invention, owing to including several layers of plastic sheeting, can increase warming effect, strengthen antiwear property simultaneously;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.And if when in use outside plastics are because causing sunshine breakage or lighting efficiency to be deteriorated, outer layer can be struck off, or plastics being taken off turnable use.
Below by drawings and Examples, technical scheme is described in further detail.
Accompanying drawing explanation
Fig. 1 is the three-layer plastic film sections schematic diagram 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 three-layer plastic thin film of a kind of agricultural greenhouse, including the outside plastic sheeting that two-layer is parallel, an intermediate layer being parallel to outer layer is also had between double-layer films, have the most respectively between intermediate layer with two outer layers and be connected plastic layer, in order to connect intermediate layer and two outer layer plastics, connected mode for building up " it " shape by articulamentum plastic folding, burst is staggered with intermediate layer and outer membrane successively to be connected, each section of folded length of articulamentum plastics is equal, and outer bilayer plastic sheeting, intermediate layer plastics and two articulamentum thin film form triangular prism and adjoin each other.
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 three layers, three-layer plastic thin film 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 three surface layers that i.e. use same material between three layers connect formation certain angle, the rock-steady structure utilizing triangle strengthens supportive, under this kind of connected mode, inside and outside two-layer, intermediate layer plastics are straight line parallel to each other with the connecting line of articulamentum plastics.
Further, air it is full of in interlayer, when making thin film be in complete extended position, in interlayer, articulamentum plastics are 45 degree with the angle of outer surface, structure is the most stable, the parallel lines distance 5 millimeters to 8 millimeters that homonymy junction is formed, this thin film portability and heat-insulating property can reach preferably balance.During commercial production, for satisfied different requirements, typically angle is set between 38 degree to 52 degree.
Further, this three-layer thin-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, the present invention, on the basis of existing common agricultural greenhouse plastics, by using 5 layers of plastics to be set to three-decker, 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.

Claims (2)

1. the three-layer plastic thin film of an agricultural greenhouse, it is characterized in that, including the outside plastic sheeting that two-layer is parallel, an intermediate layer being parallel to outer layer is also had between double-layer films, have the most respectively between intermediate layer with two outer layers and be connected plastic layer, in order to connect intermediate layer and two outer layer plastics, connected mode for building up " it " shape by articulamentum plastic folding, burst is staggered with intermediate layer and outer membrane successively to be connected, each section of folded length of articulamentum plastics is equal, and outer bilayer plastic sheeting, intermediate layer plastics and two articulamentum thin film form triangular prism and adjoin each other.
The most according to claim 1, it is characterised in that to be full of air in interlayer, when making thin film be in complete extended position, in interlayer, articulamentum plastics are 38-52 degree with the angle of outer surface, the parallel lines distance 5 millimeters to 8 millimeters that homonymy junction is formed.
