What kinds of transparent materials are used in agricultural greenhouses?

An agricultural greenhouse is an artificial environment that collects and retains solar energy through transparent materials, providing a suitable growing environment, thereby extending the growing season of plants and increasing production. Transparent materials play a key role in agricultural greenhouses, not only have good light transmission properties, but also have the characteristics of weather resistance, corrosion resistance and maintenance. The following are several transparent materials commonly used in agricultural greenhouses:

1. Glass: Glass is one of the most common transparent materials for agricultural greenhouses. It has excellent light transmission and thermal insulation properties, can absorb and retain most of the daylight, so that the greenhouse inside to maintain a suitable temperature. Glass also has good weather resistance and breathability, which can prevent plants from being affected by the external environment.

2. Plastic film: Plastic film is a relatively economical and practical agricultural greenhouse transparent material, mainly made of polyethylene and polyvinyl chloride and other materials. It has good light transmission, heat preservation and rain and snow resistance, and is suitable for agricultural greenhouses under various climatic conditions. At the same time, the plastic film also has the characteristics of light weight, easy to install and replace, and can meet the needs of different shapes and sizes of greenhouses.

3. Polycarbonate board: polycarbonate board is a transparent material with excellent transparent properties, mainly made of polycarbonate resin. It has excellent weather resistance, impact resistance and heat insulation, and can absorb and retain solar energy, while resisting the cold and hot shock of the external environment. Polycarbonate panels also have the characteristics of light weight, easy processing and installation, and can meet the different shapes and requirements of agricultural greenhouses.

4. Polyurethane foam board: Polyurethane foam board is a kind of thermal insulation material made of polyurethane as the base material, which has excellent thermal insulation performance. It has the characteristics of light weight, heat insulation, moisture resistance, etc., and can be freely cut and assembled for easy use in combination with other materials. Polyurethane foam board is mainly used for thermal insulation and thermal insulation foam materials in agricultural greenhouses.

5. Polymer transparent sheet: Polymer transparent sheet is a transparent material made of polymer materials, such as polypropylene, polyvinyl chloride and photoconductive polymers. It has good light transmission performance and impact resistance, and can resist the cold and hot shock of the external environment. At the same time, the polymer transparent sheet has the characteristics of light weight, strong weather resistance, corrosion resistance and easy processing, which is an ideal transparent material for agricultural greenhouse.

In addition to the above common transparent materials, there are some new transparent materials are gradually used in agricultural greenhouses, such as plexiglass, polyethylene terephthalate materials and so on. These materials have unique advantages in light transmission, weather resistance and maintenance, and can meet the needs and requirements of different greenhouses. With the continuous development and innovation of science and technology, the transparent materials used in agricultural greenhouses will also be constantly updated and improved to provide a better growing environment for agricultural production.
