What are the advantages of PC board greenhouses

1. Strong light transmittance and UV protection

Most of the PC board greenhouses use double-layer transparent color solar panels. Because the double-layer transparent solar panels are light in texture and strong in light transmission, they are conducive to plant growth. There is no dead-angle sunlight in the greenhouse, and the land use efficiency and lighting performance have been unprecedentedly improved. It is important that the use time does not significantly reduce the transparency.

At the same time, special high-tech anti-ultraviolet technology is used to treat the surface of solar panels to ensure the stability of the product's anti-ultraviolet rays and maintain the optical performance of the product itself for a long time. Ultraviolet radiation is not easy to cause rapid aging of the product, and the color of the product itself is not easy to turn yellow.

2. Strong impact resistance and high temperature resistance

PC is one of the materials with the best impact resistance in thermoplastics. Even if the potential degradation is small at high temperatures, the stress relaxation is also small. Solar panels made of PC have good impact resistance and can maintain stable performance for a long time in a wide temperature range (-40≤120).

Facing the impact of hail, storm, snow, ice and other severe weather conditions, it shows excellent impact resistance. Under the above conditions, glass and plexiglass are brittle and hard, while the PC board used by Zhongnong Jinwang is Flexible, such as small sawtooth grooves or deformation of the compression belt, rather than bursting.

At the same time, it can adapt to various severe weather changes from severe cold to high temperature. The low temperature embrittlement temperature is -100℃, the high temperature softening temperature is 146℃, the long-term allowable temperature is -40℃~+120℃, and the short-term bearing temperature is -100℃+135℃. Under this condition, other panels will be significantly deformed or even completely destroyed, but PC solar panels still have excellent physical properties.

3. Heat insulation and sound insulation performance

Coefficient of linear expansion: one of synthetic resins with a small coefficient of linear expansion. The coefficient of linear expansion of the PC board is slightly different in different directions. The thermal conductivity of the PC board and the thermal conductivity of ordinary synthetic resin are on average 0.065 mm, and the temperature is 1:4, 1:300, 1:1000 and 1:12000. There is a big difference between the bottom and it is a material with good thermal insulation properties.

4. Energy-saving performance and anti-droplet performance

Compared with other ordinary glass and plastics, the solar panels used in Henan greenhouses have lower thermal conductivity and greatly reduced heat loss, achieving the purpose of energy saving and consumption reduction, and they are environmentally friendly materials. At the same time, the use of German Bayer material anti-drip technology, after the high-tech infrared special process treatment, the surface of the lower plate is evenly distributed, and the high-concentration coating is used to avoid the drop in light transmittance caused by water mist, and to avoid direct and vertical condensation. The damage caused by dripping water to subsequent animals and plants.

5. Flame-retardant and fire-resistant

The PC solar panel has good waterproof performance. It has been tested by the National Fire Protection Building Material Quality Supervision and Inspection Center, and it meets the GB8624-1997 standard and reaches the B1 level of refractory materials. In addition, solar panels will not promote the spread of fire under strong flames. Solar panels will not produce dense smoke and toxic gases during the combustion process, and will automatically extinguish after a fire, indicating that solar panels have good flame retardancy. sex. It has been highly evaluated in several major fire protection tests in advanced countries in the world.

The PC solar panels used in Henan greenhouses are light and cheap, have a neat and beautiful appearance, do not damage the shed film, and the high-strength greenhouse skeleton is light, and the weight of the cement skeleton is only 1/3 of the weight of the cement skeleton. The cost is low and the market profit margin is large. The skeleton is neat, beautiful and generous, and the film surface is smooth without protruding, and does not damage the shed film, effectively prolonging the service life of the shed film.

The greenhouse should pay attention to the following points:

First, the rainy season should be avoided in the greenhouse season, and the soil quality is best not to choose sand to protect water and fertilizer.

Second, the construction of the shed can be completed by excavating the shed for rent, so that the first construction of the shed will save a lot of costs, while ensuring the height, width and width of the front wall, as well as the width of the shed.

Third. The quality and specifications of PC solar panels should also be strictly enclosed, which will affect the quality of life of the shed, the temperature in the shed, and the quality and yield of vegetables.

Fourth, the seedling stage should also be well controlled. In addition, drainage should be done well when it rains.
