Abstract
The utility model discloses a high-transmitting low-scattering glass which comprises a low-iron ultrawhite glass substrate, wherein a sueded embossing layer is arranged on the low-iron ultrawhite glass substrate and comprises a plurality of smooth connected scraggly irregular curves, and the height difference of a highest point and a lowest point is 0.8-1.5 micrometers; an orange peel embossed pattern is arranged under the low-iron ultrawhite glass substrate and comprises the plurality of smooth connected scraggly irregular curves, and the height difference of the highest point and the lowest point is 0.03-0.06 millimeters; and antireflection films are arranged above and below the low-iron ultrawhite glass substrate. The high-transmitting low-scattering glass disclosed by the utility model achieves the high light transmittance by 99% and the haze value by 20%+/-5%. According to the utility model, after sunlight transmits through the glass, scattered light rays are uniformly distributed on the surface of a crop and deeply irradiated to the crop, the light rays are moderate, the temperature of the leaf surface of the crop is reduced to about 5 DEG C, the temperature difference of the leaf surface and rhizome of the crop is low, the illumination intensity is lower than the saturated light intensity of the crop, and the effect of reducing photoinhibition action is obvious, so that the net photosynthetic rate is enhanced, and the purpose of agricultural yield increase is achieved.
Description
Technical field
The utility model relates to the low diffusion glass of a kind of high printing opacity, and specifically a kind of warmhouse booth hangs down diffusion glass with high printing opacity.
Background technology
The formation of crop yield, the mainly photosynthesis by the green plants blade.According to one's analysis, the growth of the whole dry weights of crops, 90%～95% directly from the photosynthesis of greenery, has only 5%～10% inorganic substances (water and salt) from the root system absorption.According to estimates, annual by the fixing CO of photosynthesis on the earth
2About 7 * 10
11Ton, amounting to into organic matter then is 5 * 10
11Ton.By the photosynthesis plant directly for the mankind provide a large amount of grain, cotton, oil, tea, really, grain, commodity and the raw material of industry such as vegetables, medicine, fiber crops.This shows that photosynthesis is a central issue of crops high yield.Photosynthetic power not only reflects the growth level of crop itself, and is directly connected to the yield and quality of agricultural product.
Photosynthesis is a photobiochemistry reaction, photosynthetic rate is the speed of photosynthesis stabilizing carbon dioxide (or producing oxygen), the relation of being in line between photosynthetic rate and intensity of illumination, its aggregate velocity is accelerated along with the increase of intensity of illumination, but when intensity of illumination further is increased to full when closing luminous intensity, the increase of photosynthetic rate is slack-off, light namely occurs and suppresses, and photosynthesis descends.
The high-efficiency agriculture warmhouse booth is for improving crop yield, generally at warmhouse booth top cover glass, in the hope of improving canopy temperature, improve crop yield, but common glass light transmittance is low, no scattering function, at some high latitude areas such as China northeast, the elevation angle of sunshine is little, solar radiation is few, the blocking of adjacent crop makes the sunlight intensity differentiation that crop obtains, part crop produces light and suppresses because intensity of illumination is excessive, part crop illumination undercapacity and cause photosynthetic speed not enough, and then cause the crop yield effect bad, therefore, how to make solar irradiation intensity more even, improve saturated light intensity, and then raising Net Photosynthetic Rate, reaching agricultural produce is present high-efficiency agriculture urgent problem.
The utility model content
At above-mentioned defective, the utility model provides a kind of high transmission rate to hang down diffusion glass, the transmitance height of glass, and have low scattering function, and make the interior crop of warmhouse booth obtain uniform solar radiation, make intensity of illumination be lower than the full luminous intensity of closing, improve Net Photosynthetic Rate, reach agricultural produce.
To achieve these goals, the technical solution of the utility model is: a kind of high printing opacity hangs down diffusion glass, comprise glass substrate, described glass substrate is low iron ultra-clear glasses substrate, the matte embossed layers is set above the described glass substrate, scraggly irregular curve by numerous smooth connections is formed, and the peak of described matte embossed layers irregular curve and the difference in height of minimum point are 0.8～1.5 μ m; The tangerine peel embossed layers is set below the described glass substrate, is made up of the scraggly irregular curve of numerous smooth connections, the peak of described tangerine peel embossed layers irregular curve and the difference in height of minimum point are 0.03～0.06 ㎜; On the described matte embossed layers He on the tangerine peel embossed layers anti-reflection film is set.
Further, the thickness of described anti-reflection film rete is 100～180nm.
Further, described anti-reflection film is made up of a silica material of sodium meter level.
High printing opacity of the present utility model hangs down diffusion glass, can be used for some high latitude areas such as northeast, according to the actual measurement of greenhouse production research institute of Dutch Wa Hening university, its light transmittance is up to 99%, haze value is 20% ± 5%, sunshine is after seeing through this glass, and scattered beam is evenly distributed on crop surface, and more deeply shines crop, even the light under the Liege in the greenhouse is still gentle, compare with simple glass, the temperature of crop leaf table reduces about 5 ℃, and the temperature difference of crop leaf table and rhizome is little, intensity of illumination in the booth is lower than the full luminous intensity of closing of crop, reduce light and suppress obvious with effect, thereby improve Net Photosynthetic Rate, reach the purpose of agricultural produce.
