Speaking of haze, we have to talk about the exquisite greenhouse cover glass. At present, the greenhouse glass related to the haze mainly includes scattering glass and anti-reflection glass. Other glasses do not have the concept of haze, and the haze is purely for greenhouse scattering glass. To define.
1. What is haze
The light passing through the greenhouse glass shifts beyond 2.5° as scattered light, and the proportion of scattered light is haze. You can understand that it defines the transparency of the material by the deflection angle of the scattered light, and the hemispherical transmittance is not the direct transmittance.
2. What is the relationship between haze and glass transmittance
An important indicator of greenhouse diffuse glass products is light transmittance. Better light transmittance can ensure sufficient light and uniformity of light inside the greenhouse. When talking about haze, we must first introduce a concept, hemispherical transmittance.
3. What is hemispherical transmittance
The popular explanation for the light transmittance of the diffuse glass hemisphere of the greenhouse is that when the earth rotates, the sun's rays change during the day, and it will illuminate the interior of the greenhouse from all angles. In the change of day and night, the intensity of light is not the same, and the average light transmittance of the all-weather light intensity is the hemispheric light transmittance.
The light transmittance we are talking about generally refers to the direct light transmittance, so the relationship between the haze, light transmittance, and hemispherical light transmittance is that the light transmittance determines the highest light transmittance of the greenhouse diffuser glass, and the hemispherical light transmittance determines the total light transmittance of the glass. The intensity of day light and haze determine the flux of light
The haze and hemispherical light transmittance are in inverse proportion, the higher the haze, the lower the hemispherical light transmittance, and vice versa.
4. What is the role of haze
After talking for a long time, the most direct question came, what is the role of haze. We know that many regions have harsher climates, such as Africa and some desert areas. Not only are droughts, but windy, sandy, high temperature and other climates seriously affect the growth of crops. The haze can just suppress the intensity of light, so that the light inside the greenhouse is always suitable for plant growth, and can effectively reduce the leaf surface temperature without burning the leaf surface.
5. Will the haze affect the price of greenhouse glass?
The choice of the haze of the diffuser glass in the greenhouse will not affect the price of the glass, so you can choose with confidence.
6. How to choose the haze of the greenhouse diffuser glass
You can consult the manufacturer for specific purchase criteria. The selection index of haze is more complicated. There are more data to be understood. Generally, you need to purchase based on data such as local temperature and light. Finding an experienced manufacturer can quickly fill the knowledge gap.
