Description
Technical Field
The invention relates to the field of film manufacturing, in particular to an assembled heat-preservation breathable greenhouse film.
Background
The current vegetable greenhouse film is usually of a single-layer design, a large amount of water vapor can be generated due to sunlight irradiation or the breathing effect of plants, and the vegetable greenhouse film is good in tightness, cannot be penetrated out, can cause stuffiness in the greenhouse, can be condensed after being cooled, falls on the body of a worker, and is very inconvenient to use.
The single-layer greenhouse in the prior art is poor in heat preservation performance, large in day and night temperature difference, large in temperature difference in the greenhouse, and incapable of effectively simulating constant temperature control.
When changing greenhouse dimensions, the greenhouse film size may not match the new greenhouse dimensions, and if the film dimensions need to be modified, the process is cumbersome.
Therefore, it is necessary to develop a vegetable greenhouse film which is heat-insulating and breathable, and can be conveniently adjusted in size.
Disclosure of Invention
In order to overcome the problems, the invention provides the assembled heat-insulating breathable greenhouse film which has good external waterproof property, good heat-insulating property, good air permeability and convenient and adjustable size.
The technical scheme of the invention is to provide an assembled heat-insulating breathable greenhouse film, which is formed by assembling a plurality of assembled unit films, wherein each assembled unit film comprises a woven reticular bottom film and a covering film positioned on the outer side of the woven reticular bottom film, the upper side of the covering film is fixed with the upper side of the woven reticular bottom film, and the lower side of the covering film is fixed with the lower side of the woven reticular bottom film through a porous breathable cushion; the interlayer formed between the woven reticular bottom film and the covering film is filled with heat-insulating particles; and the upper part of the outer side of the woven mesh-shaped bottom film is provided with a first connecting component, and the lower part of the inner side of the woven mesh-shaped bottom film is provided with a second connecting component which is matched with the first connecting component in a shape.
The first connecting component can be connected with the second connecting component, namely, one assembled unit film can be connected with the other assembled unit film, and the assembled unit film can be assembled to a proper size according to the requirement. The first connection component and the second connection component can be selected from connection components commonly used in the field, and in the invention, preferred modes include, but are not limited to, velcro, concave-convex buckles and snap buckles. The structure can effectively connect the assembled unit films.
In a preferred embodiment, the woven mesh base film is woven by means of 3 or 4 or 6 needles. The woven mesh has certain light transmission and air permeability, the higher the number of selected needles is, the denser the woven mesh is, the smaller the pores are, and the lower the light transmission rate is. The above-mentioned mesh grid can be woven according to the demand to different illumination, selects suitable needle number, and the preferred needle number is 4 needles.
In a preferred embodiment, the insulation particles are transparent PET polyester particles or transparent PE particles. The transparent particles can ensure certain light transmittance. The particles have a large amount of air between them, and the air is a bad conductor of heat, so that the transparent particles arranged between the woven mesh-shaped base film and the covering film can have good heat preservation effect. Preferred transparent particles are selected from transparent PE particles.
In a preferred embodiment, the underside of the porous pad forms a ventilation opening that is oriented toward the ground. The porous air-permeable mat may be selected from porous sponges or foamed plastics, preferably porous sponges. In general, vegetable plants in a greenhouse adopt a scientific water supply mode, and precipitation in the atmosphere breaks the balance, and when adopting the structure, even if rainfall or snowfall occurs, the rain and the snow can fall from an external coating film, and meanwhile, the ventilation of the interior and the exterior of the greenhouse is not hindered.
In a preferred embodiment, the tops of the assembled heat-preserving breathable greenhouse films are connected by upright lock seams. In the case of covering the whole greenhouse, two independent and symmetrically arranged greenhouse films are needed to ensure that the directions of the ventilation openings are all towards the ground. At this time, the joint of the two greenhouse films needs to be vertically sewn, so that the fastening connection of the two greenhouse films is ensured, and water leakage at the joint is avoided.
In a preferred embodiment, the assembled unit film has a thickness of 0.3 to 1cm, and an excessive thickness may result in the entire film layer being too heavy, affecting safety performance. Correspondingly, the average particle diameter of the filled heat-insulating particles is 0.1-0.5cm.
In a preferred embodiment, the width of the assembled unit film is 5-10cm, which is a relatively moderate width value, and too much width results in that the heat-insulating particles are accumulated in the middle-lower layer of the interlayer formed between the base film and the cover film due to gravity because of too much heat-insulating particles contained therein, and too much width results in insufficient heat-insulating effect.
The beneficial effects of the invention are as follows:
1. The assembled heat-insulating breathable greenhouse film has the advantages that through the unique design, the greenhouse film can resist external rain and snow, meanwhile, the heat-insulating effect on the interior of the greenhouse can be achieved, and meanwhile, water vapor and the like generated in the interior of the greenhouse can be exchanged with the atmosphere, so that the breathable effect is achieved.
2. The assembled heat-insulating breathable greenhouse film can adjust the needle number of the woven mesh-shaped bottom film according to actual requirements, so that the light transmittance of the greenhouse film can be adjusted according to local conditions.
3. The size of the assembled heat-insulating breathable greenhouse film can be controlled by adjusting the number of the assembled unit films, and the assembled heat-insulating breathable greenhouse film is convenient to assemble, so that the greenhouse film can be reused more effectively.
4. The assembled heat-preservation breathable greenhouse film is convenient to use and can be directly covered on a greenhouse framework.
