There are many types of greenhouses. Customers can build greenhouses of different types and sizes according to their needs. Diversified greenhouses have greatly promoted the development of agriculture. Greenhouses are one of many types of greenhouses. Compared with other types of greenhouses, they have certain advantages. It is precisely with these advantages that they have won the recognition of many customers. Although greenhouses are widely used in the market, many details need to be paid attention to when building greenhouses to ensure the overall quality of greenhouses. So, what requirements are required for greenhouses to be of qualified quality?
1. Good light transmission effect. Greenhouses are lighting buildings. Therefore, when building greenhouses, certain light transmission conditions must be met. Light transmittance is the basic indicator for evaluating the light transmission performance of greenhouses. Light transmittance refers to the percentage of light entering the greenhouse and the amount of outdoor light. The light transmittance of the greenhouse is affected by the light transmission performance of the greenhouse light-transmitting covering material and the shadow rate of the greenhouse stock price. Later, with the different angles of solar radiation in different seasons, the light transmittance of the greenhouse is also changing at any time. Then the light transmittance becomes a direct factor affecting crop growth and the selection of plant species.
2. Good thermal insulation performance. By improving the thermal insulation performance of the greenhouse, energy consumption can be reduced as much as possible. The thermal insulation ratio of the greenhouse is an important indicator for measuring the thermal insulation performance of the greenhouse. The thermal insulation ratio of the greenhouse refers to the ratio of the coverage area of the greenhouse light-transmitting material with smaller thermal resistance to the coverage area of the greenhouse maintenance structure with larger thermal resistance. The larger the thermal insulation ratio, the better the thermal insulation performance of the greenhouse.
3. Durability. The durability of the greenhouse is affected by the aging resistance of the greenhouse material. The durability of the light-transmitting material is affected by factors such as the bearing capacity of the main structure of the greenhouse. In addition to its own strength, the durability of the light-transmitting material also reflects the continuous attenuation of the material’s light transmittance over time. The attenuation degree of light transmittance is the determining factor affecting the service life of the light-transmitting material. Since the greenhouse is in a high temperature and high humidity environment for a long time, the anti-corrosion of the surface of the structure is also one of the important factors affecting the service life of the greenhouse.
