First, good light transmission
1. High light transmittance
The light transmittance of the PC board can reach about 80%-90%, which can allow a large amount of natural light to enter the greenhouse. This is very important for plant photosynthesis, because sufficient light can ensure that plants effectively absorb carbon dioxide, synthesize organic matter, and promote plant growth and development. For example, in the flower planting greenhouse, good light transmission can make the flowers bright in color, thick petals, and higher ornamental value.
2. Light is evenly distributed
The PC board has astigmatism, which can make the light entering the greenhouse evenly distributed in all corners of the greenhouse. Compared with glass greenhouses, PC board greenhouses do not appear local light is too strong and lead to plant burns. This is like in a greenhouse covered with PC board, the plant is like a layer of soft light curtain, each leaf can receive more uniform light, conducive to the overall growth of the plant. |
Second, excellent insulation performance
1. Good heat insulation effect
The PC board has a multi-layer structure, and the hollow part in the middle can effectively prevent the transfer of heat. Its thermal conductivity is low, generally about 2.3-3.0W /m² · K, much lower than ordinary glass. In winter, it can reduce the loss of heat in the greenhouse and play a good role in heat preservation. For example, in the vegetable greenhouse in the north, the use of PC board as a covering material can make the temperature in the greenhouse about 10-15 ° C higher than the outdoor temperature, providing a suitable temperature environment for the winter cultivation of vegetables.
2. Obvious energy-saving effect
Due to the good thermal insulation performance of the PC board greenhouse, it reduces the dependence of the greenhouse on heating equipment at night or in cold weather, thereby reducing energy consumption. In the long run, it can save a lot of costs for the operation of the greenhouse, such as in some flower seedling greenhouses that need to maintain a constant temperature, the use of PC board can reduce the running time of the heating equipment, save electricity or other energy. |
Third, strong impact resistance
1. High physical strength
The impact strength of PC board is 250-300 times that of ordinary glass. It can withstand greater external impact without breaking, which is very important for the greenhouse. For example, in some areas that are prone to natural disasters such as hail, PC board greenhouses can effectively resist the impact of hail and protect the plants and equipment in the greenhouse. Even with larger hail, the PC board will only show some dents, and will not break like glass, resulting in exposure to the harsh environment inside the greenhouse.
2. High security
Because the PC board is not easy to break, during the use of the greenhouse, whether the operator is operating inside the greenhouse, or the accidental collision that may occur outside the greenhouse, there will be no safety hazards due to material breakage. For example, when picking and other activities in the greenhouse, even if you accidentally touch the covering material, you do not have to worry about being scratched by debris. |
Fourth. Long service life
1. Good weather resistance
PC board can withstand a variety of harsh weather conditions. It has a good tolerance to ultraviolet light, because ultraviolet absorbers are added in its production process, which can effectively prevent the damage of ultraviolet light to the plate. At the same time, it can be used normally in the temperature range of -40 ° C to 120 ° C, whether it is cold in the northern winter or hot in the southern summer, PC board greenhouse can maintain stable performance. For example, in the seaside greenhouse, the PC board can resist the erosion of the sea breeze and the corrosion of salt spray, and the service life can reach more than 10 years.
2. Good chemical stability
PC board has a good tolerance to most chemicals. It does not react with common greenhouse pesticides, fertilizers and other chemicals, thus ensuring its own integrity and stability. In a long-term greenhouse environment, even if pesticides and other chemicals are often used, PC board can maintain good performance, reduce material damage caused by chemical corrosion, and further extend the service life. |
Fifth. Easy installation and maintenance
1. Light weight, easy to install
The weight of the PC board is relatively light, about 1/12-1/15 of the weight of the same thickness of glass. This makes it easier to install PC boards during the greenhouse construction process, without the need to use large lifting equipment. The construction personnel can easily move the PC board to the skeleton of the greenhouse for installation, and simple installation tools can be used, such as special sealing strips and card slots, to speed up the installation.
2. Easy to maintain and clean
PC board surface is smooth, dust and dirt is not easy to adhere. When you need to clean, you can use ordinary cleaning agents and soft cloth to wipe, you can make the PC board to restore good light transmission. And if there is local damage to the PC board, such as a small area of scratch or rupture, it is also relatively easy to replace, only need to remove the damaged part of the PC board, install a new plate, not like the glass greenhouse, once a piece of glass is damaged, it is more complicated to replace. |
