Description
Technical field:
The utility model is about horticultural facility, particularly about the sunshade curtain.
Background technology:
Glass greenhouse is the early stage a kind of horticultural facility that occurs, and it utilizes the daylight of transmission and manually heats, and is beneficial to create cold winter an environment that is suitable for plant growing.Because its weight is big, the cost height, utilization rate is low, the usefulness that only limits to plant some famous and precious flowers and trees in the past or do scientific research.Along with development of science and technology, heavy glass progressively is that light compound resin plate substitutes, Refrigeration Technique, artificial microclimate's control technology are constantly improved and are progressive, the annual availability in greenhouse also improves constantly, its cost and use cost are still quite high, can't large tracts of land promote in agricultural production.Owing to the plastic foil appearance of inexpensive, light weight, printing opacity, a kind of easy greenhouse---plastic tunnel is on horticulture, and especially the plantation aspect of vegetables has obtained to use widely.Not only use winter, and become the production facility of long-term use.Agricultural science discloses, and light radiation intensity is reduced in the back before midday, has the effect of cooling and reduction light compositing speed, and this generation to crops is very favourable.So occurred various and the sunshading facility supporting and independent use in greenhouse, they belong to two big classes basically, a class is cancellated sunshade net, and they use the plastics rope yarn of coloured (mostly being black) or narrow black thick film bar to form usually.Part sunlight is outside the mesh transmission, and all the other are all partly covered by nettle, and it has simple in structure, easily manufactured advantage, its weak point is bulky, benzene is heavy, operation inconvenience, the base material of particularly coloured (black) absorbs a large amount of heat energy, influences temperature in the greenhouse, is unfavorable for adjustment.Though so certain sunshading and temperature reducing effect is arranged, effect is not ideal enough.But its cost is low, and low price is used wider in China.Another kind of is the sunshade curtain, and it is that the curtain framework interlocking that the thin slice of long narrow high-transmission rate and high reflectance is parallel to each other that utilizes warp, latitude to interweave forms a curtain on this curtain framework.At present the high-transmission rate thin slice that generally uses is that polyethylene film cuts and forms; The thin slice of high reflectance then is the simple metal of lightweight or the aluminium foil of coating, it is little that this sunshade curtain has a volume, light, convenient folding rolling, good permeability, not ponding, the advantage, particularly aluminium foil of dripping, it not only stops passing through of light, and absorbs the most of reflection of the radiant heat energy of sunshine few.Therefore less to the temperature effect in the room temperature, be convenient to artificial temperature control.Though its complex structure, manufacturing cost is higher; But it helps mechanically actuated, influences the less energy consumption of the artificial temperature control input in greenhouse, and effective, so widely use in West Europe gardening developed country, China also has introduction at present.The defective of this sunshade curtain is that aluminium foil in use produces the corrosion damage, perhaps aluminium coated can corrode and comes off, especially in the greenhouse this humidity height, have under the condition of uniform temperature again, this destructive process of the easier quickening of etchant gas in the environment, make whole sunshade curtain lose effect, the facilities horticulture of China is looped around big or middle city and rises all around, and the pollution of urban air just constantly worsens.Therefore will extensively promote advanced sunshade curtain, the corrosion that must solve aluminium lamination comes off.In addition, aluminium is good thermal conductor, and when night, the temperature in the greenhouse is higher than outdoor, and indoor heat (comprising a large amount of underground heat) sheds outdoor by aluminium lamination, be unfavorable for plant growth.If keep a suitable growing environment, need drop into certain energy again and carry out manual adjustment.
For this reason, the purpose of this utility model is to provide a kind of reflective energy-saving sunshade curtain, and it mainly solves the technical problem that the corrosion of aluminium lamination comes off, and the technical problem of heat conduction loss.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of reflective energy-saving sunshade curtain; comprise curtain framework by radial line and parallel braiding; each other alternately and radially be embedded in hyaline membrane bar and metallic reflective coating bar in this curtain framework abreast; it is characterized in that: this metallic reflective coating bar is aluminium lamination, the upper and lower complex reflex film bar that is provided with protective clear layer in the middle of being.
Above-mentioned reflective energy-saving sunshade curtain, it is characterized in that: the aluminium lamination of this metallic reflective coating bar is divided into upper aluminum layer and lower aluminum layer; Between this upper and lower aluminium lamination, be provided with the microporous foam layer.
Above-mentioned reflective energy-saving sunshade curtain is characterized in that: this protective clear layer is polyethylene, polyvinyl chloride or polyester plastics film, preferably is added with the sealed polyethylene plastic of the anti-insecticides adjuvant of uvioresistant.
Above-mentioned reflective energy-saving sunshade curtain is characterized in that: this hyaline membrane bar is polyethylene, polyvinyl chloride or polyester plastics film, preferably is added with the polyester plastics film of ultraviolet-resistant aid.
The utlity model has following advantage:
1, the two sides of exposing as the aluminium lamination that reflects sunshade all completely cuts off its etchant gas with the external world with transparent plastic protective layer, neither influences the function of its reflection sunshade, prevents effectively that again its corrosion from coming off, and has prolonged service life.
2, plastic protective layer can reduce heat conduction loss, particularly increases the microporous foam layer in upper and lower aluminium lamination, has blocked the heat conduction approach of aluminium lamination, can prevent the escaping of stratum hot line of wavelength 5000-10000nm effectively.Thereby can make in the greenhouse in summer 4-7 ℃ of temperature decline, improve ground temperature winter and can reach 5-8 ℃, save energy, fractional energy savings can reach 50-80%.
3, have strong uvioresistant effect, not only can prevent burning crop; And improved the anti-degradation capability of plastic film, and increase the service life, reduce use cost.
