Abstract
The utility model relates to an agricultural honeycomb plastic film which is greenhouse covering material whose surface is a honeycomb shape. The agricultural honeycomb plastic film is characterized in that a plurality of rows of polygonal or circular closed columns are alternatively arranged on a flat film. Thus, the insulating power, and the mechanical strength, and other performance aspects of the agricultural honeycomb plastic film are superior to an ordinary single-layer plastic film for a greenhouse. The utility model is suitable for the productions of agriculture and animal husbandry, and can be widely used in ordinary greenhouses.
Description
The utility model is a kind of agricultural greenhouse cladding material.The agricultural plastic film that generally uses at present is the individual layer plastic film, and low, the effective definite value phase of insulating power is short, and energy consumption is higher when being used to heat the greenhouse.Again because relatively poor general of mechanical strength is used first and second i.e. breakage.Report about the agricultural plastic film of bilayer was once arranged both at home and abroad, but, be difficult for promoting because supporting structure complexity, the cost of this covering method are higher.
The design's purpose is to make to be cellular agricultural plastic film on a kind of surface, is better than common greenhouse individual layer plastic film in the overall target of aspect of performances such as insulating power, mechanical strength, and popularization in agricultural, livestock breeding are produced easily.
Describe the structure of agricultural honeycomb plastic film below in detail.The staggered every trade polygon that is arranged with seals round sealed cylinder shown in cylinder or the accompanying drawing 2 on the flat as shown in Figure 1 film, the axis of a cylinder spacing is 7--25mm, polygonal side length (or round diameter) is 6--20mm, and sealing cylinder height is 2.4--20mm, and two line spaces are 7--25mm.Staggered every trade sealing cylinder has promptly formed the alveolate texture on agricultural plastic film surface.
When solar incident angle is that most of the time on daytime iuuminting rate is not less than 0.7 in 70 ° of scopes of 0 ┄.The light transmittance loss is bigger after solar incident angle exceeds above-mentioned scope.But be early morning or near night, outdoor emittance is very low this moment.Agricultural honeycomb plastic film is compared with the individual layer plastic film with common greenhouse, because its surface is added with one deck honeycomb, heat retention can improve more than 25%.Light transmittance loss 5-10%.And mechanical strength is used the individual layer plastic film much larger than common greenhouse, and is suitable for industrial batch process, although cost is higher relatively, from its resultant effect economic benefit still significantly.Agricultural honeycomb plastic film is the desirable regeneration product of at present widely used common greenhouse with the individual layer plastic film.
Embodiment: adopt cylindrical honeycomb.Body diameter D=6mm, the high H=4mm of post, axis of a cylinder spacing A=8.5mm.Test greenhouse height is 1.7m, and span is 2.5m.Result of the test sees the following form:
