Anti-reflective glass is a specially developed glass type used for greenhouse roofs. The production process for anti-reflective glass is as follows: ultra-clear float glass (embossed) – ultra-clear Nashiji diffuser glass – ultra-clear Nashiji anti-reflective glass (coated). (Note: All of these glass types are tempered glass.)
Differences between greenhouse Nashiji anti-reflective glass and other glass types:
First: Haze
Visually, haze indicates opacity. Because of the embossing, it appears hazy, but light transmittance is not reduced.
Nashiji anti-reflective glass has eight haze levels, like a scale, corresponding to different levels of scattered light.
Second: Light transmittance
As the primary covering material for greenhouse roofs, high light transmittance means higher greenhouse productivity. The standard light transmittance of greenhouse anti-reflective glass is 97.5%. In the blue-violet wavelength range required for crop growth, the light transmittance of anti-reflective glass can reach over 99%.
Third Point: High Yield Increase
Anti-reflective glass is developed and manufactured specifically for glass greenhouses. Its purpose is to increase light transmittance and productivity. Compared to greenhouses using ordinary ultra-clear float glass, anti-reflective glass increases yield by over 30%.
Fourth Point: No Drip
The no-drip feature was also developed specifically for greenhouses. Greenhouses are inherently hot and humid environments. Due to temperature fluctuations, condensation forms on the top glass. Using ordinary glass for coverings, these droplets can condense and drip, potentially damaging seedlings inside.
Anti-reflective glass allows condensed droplets to spread evenly and quickly air dry, preventing condensation and dripping, which could harm greenhouse crops.
Fifth Point: High Safety
As agricultural structures with a height of 5-7 meters, glass greenhouses require tempered glass for their top glass.
The tempering standards for anti-reflective glass far exceed national standards. Among the technical parameters, the self-explosion rate is 0.02%, and the particle size of the self-explosion particles is >60 particles per 5 x 5 cm².
Sixth Point: Long Life
Long life primarily refers to the coating performance of Nashiji Anti-Reflective Glass for greenhouses. This anti-reflective glass is coated using an etching process. The coating layer is integral to the glass, meaning it has the same hardness as the glass.
Daily mechanical brush cleaning provides greater resistance to natural erosion, while impurities reduce transmittance.
The above are several key technical specifications for Nashiji Anti-Reflective Glass. We should focus on five key points during procurement and negotiation:
1. Light transmittance, standard 97.5%
2. Safety, self-explosion rate of 0.02%, particle size greater than 60% for 5 x 5 cm²
3. Full haze range, with multiple haze levels available
4. Long life, no worries about transmittance degradation
5. High yield increase, with comparisons to test greenhouse data
In addition, we require the following report data during procurement:
1. Light transmittance test data
2. Haze test data
3. Previous project case data
Several key technical specifications for purchasing Nashiji Anti-Reflective Glass for greenhouses. When we purchase, the best way to distinguish is to visit the factory.
The diffuse glass and AR-coated diffuse glass produced by Yuhua have cooperated with many large commercial greenhouses in agriculture, horticulture, nurseries and experiments. We have cooperated with large greenhouse project companies such as Havecon, Van Der Hoeven, Kubo, etc. for many years. Yuhua greenhouse glass has a light transmittance of up to 99%, and haze 5/10/20/30/50/70/75 greenhouse diffuse glass is available!
