The rapid development of agricultural science and technology drives the acceleration of the intelligent glass greenhouse industry. At this stage, the glass used in the glass greenhouse is basically ultra white glass or float glass, the side wall is generally double-layer hollow ordinary float glass, and the top is high light transmittance ultra white glass, but there are many kinds of ultra white glass. At present, most of the ultra white glass circulating on the market is used to supply buildings and photovoltaic.

Greenhouse crops are generally seasonal crops or off-season crops, which have different light needs. The transmittance of glass should be put in the first place. We can take a look at the transmittance of glass in various fields:

Ordinary float glass: 88%

Ultra white glass: 90%

Ultra white scattering glass: 91.5%

Ultra white photovoltaic glass: 93.5%

Ultra white antireflective glass: 97.5%

AG glass: 99%

Ar glass: 99.99%

The above glass is used in doors and windows, photovoltaic, greenhouse, museum, photo frame, electronic instrument and other industries. As long as the old glass is avoided to talk about the transmittance, and the demand for light of greenhouse glass is tricky. The main light demand of greenhouse fruits and vegetables is blue light and purple light. Therefore, the technical standard of greenhouse glass focuses on improving the transmittance of blue light and purple light. Doors and windows, photovoltaic, museums and electronic instruments are mainly used for people, so the transmittance of infrared light is relatively high, and the transmittance of blue and purple light is relatively low compared with the demand of greenhouse crops.

According to the data of global new greenhouses, diffuse glass is mainly used in large intelligent glass greenhouses in China, the United States, the Netherlands, Canada, Mexico, the United Arab Emirates and other countries according to the production increase effect and natural climate conditions. The unique haze parameter of greenhouse diffuse reflective glass can ensure that your greenhouse can balance the indoor temperature and adjust the impact of temperature difference no matter where it is. The light selection performance of diffuse reflection glass improves the transmittance of blue and purple light and reduces the transmittance of infrared light, which is also a secret weapon to ensure that diffuse reflection glass can bring yield increasing effect to greenhouse. The scattering performance of diffuse reflection glass and ultra-high scattering can ensure the uniform illumination inside the greenhouse, and there will be no phenomenon that some plants are young and lush due to different light intensity. The scattered light can also irradiate the plant roots to prevent the breeding of bacteria.
