Features of insulating glass in greenhouses: The periphery of the greenhouse is made of insulating glass. It is an excellent product. It plays the same role as the skin in the greenhouse system. Generally speaking, the insulating glass of the greenhouse is composed of two or more pieces, and the periphery is sealed.
With the advancement of skills, greenhouse gas emission rights are normal, and the results of vacuum glass thermal insulation, sound insulation and noise reduction are getting better and better, and the glass's own mass has decreased, but the load capacity has increased. Insulating glass, with its excellent features of dew condensation prevention, energy-saving insulation, sound insulation and noise reduction, China's greenhouse project has taken it to the next level, walking in front of the world's greenhouses. So what are the characteristics of insulating glass in greenhouses? How to correctly understand the importance of the greenhouse skeleton! vegetables greenhouse manufacturer share with you:
First, the selection of insulating glass is very good. The use of flexible sealing material as the material can reduce the shear force in the sealing area of the glass plate in the case of large temperature difference between the surface and the room, and overcome the failure of the brittle sealing material in the same environment. In this way, the loopholes of the greenhouse's own loss of achievements in many types of severe conditions have been eliminated.
Agricultural Glass Greenhouse
Second, the hollow glass has a high vacuum inner cavity. This is the feature that distinguishes it from other glasses. Negative gas heat transfer almost does not exist. It greatly prohibits the heat transfer of radioactive materials and ensures the heat transfer of glass. The insulation and insulation of the insulating glass in the greenhouse is twice as high as that of ordinary glass, which can satisfy the requirements for heat transfer and cooling of doors and windows.
Third, agricultural glass greenhouse selects low temperature sealing skills. On the one hand, it has the characteristics of toughened glass and resistance to attack. On the one hand, its force is well-balanced, and it will not cause damage due to collision and other reasons. It will increase the service life and is the first choice for building greenhouses. Although the insulating glass of the greenhouse can also cut off the noise and ensure the normal production of employees, in order to ensure the energy saving benefits, greening and environmental protection, choosing the growth mode of the greenhouse is the main choice for building greenhouses.
What are the factors affecting greenhouse durability?
The durability of the greenhouse is affected by the aging resistance of the greenhouse material and the bearing capacity of the main structure of the greenhouse. Multi-span greenhouse is a kind of better existence of greenhouse, in fact, it is a kind of large greenhouse. It connects the original single-room greenhouse with scientific methods, reasonable design and excellent materials to connect the original single-room greenhouse. Compared with traditional greenhouses, greenhouses and greenhouses in the form of multi-story greenhouses are a bright spot compared to traditional greenhouses, and their utilization area is much larger than traditional greenhouses. Compared with traditional greenhouses, the management is more unified, the operation is more scientific, saves time, and increases efficiency. In addition to the strength of the transparent material, in addition to its strength, it also shows that the light transmittance of the material decreases due to time, and the degree of attenuation of the light transmittance is a decisive factor affecting the service life of the transparent material. Due to the long-term operation of the greenhouse in high-temperature and high-humidity environments, the surface corrosion of components has become one of the important factors affecting the service life of the greenhouse. In greenhouse steel structures, thin-walled steel is generally used as the main stress member, and its corrosion resistance is poor. Greenhouse anticorrosive treatment uses hot-dip galvanized surface. For greenhouses with wooden or steel welded truss structures, surface anti-corrosion treatment is guaranteed once a year.
The waste heat in the equipment is discharged to keep the indoor ambient temperature within a range suitable for plant growth. The discharge of residual humidity is to keep the relative humidity of the indoor environment within a range suitable for plant growth. Adjust the air composition, reduce harmful gases, increase the CO2 content in the indoor air, and make the crop grow well.
Due to the long-term operation of the greenhouse in high-temperature and high-humidity environments, surface corrosion of components has become one of the important factors affecting the service life of the greenhouse. With the development of vegetable greenhouses in recent years, greenhouses have provided a driving force for agricultural development. Greenhouse control generally consists of three parts: signal acquisition system, computer and control system. In greenhouse steel structures, thin-walled steel is generally used as the main stress member, and its corrosion resistance is poor. Greenhouse anti-corrosion treatment should use hot-dip galvanized surface. The coating thickness reaches 150-200 microns, which can guarantee a 15-year service life. For greenhouses with wooden or steel welded truss structures, the surface of the greenhouse is protected from corrosion once a year.
