Foreword: What are the obvious applications of sunshine board in vegetable production? First, the output value can be increased and the effect of increasing production and income can be achieved. For the planting of high value-added economic crops such as Chinese herbal medicine, from seedling raising to large-scale production, it has an excellent protective effect. The reasonable matching of auxiliary greenhouse facilities can achieve more benefits with half the effort. Secondly, because the heat preservation effect of solar panels is much higher than that of other materials such as glass, it can reduce the energy consumption of the greenhouse while enabling crops to grow in a more suitable environment, and improve the quality and nutrients of the crops. Focus on greenhouse engineering technology and serve modern agriculture. The article was published by Manager Zhang of Guangyuan Greenhouse. If you are focused, please keep the source.
Type: Sunshine panels are divided into rectangular panels, rice-shaped panels, honeycomb panels, and locking panels in terms of structure. From the board type, it is divided into double-layer board and multi-layer board. Double-layer rectangular solar panels are commonly used in ordinary daylighting and shading areas. Among them, the greenhouse cover material mainly adopts 4~12mm transparent solar panels, which have the characteristics of high light transmittance, good heat preservation performance, light weight, and high cost performance. Multilayer boards are mainly used in large-scale stadiums, railway stations and other heavy-duty steel structure buildings. They are characterized by high specific gravity and good structural mechanical design load-bearing performance. According to the number of years, it is divided into 3 years and 5 years. The quality of the sunshine board manufacturers can reach 10 years. The current production technology of Sunshine Board is very mature, and the production technology and quality control are becoming more and more standardized. The current production process is mainly based on extrusion process, and the main production equipment used is divided into two types: imported and domestic.
Advantages: The light transmittance of the solar panel is as high as 89%, which is comparable to glass. UV-coated panels will not cause yellowing, fogging, and poor light transmission when exposed to sunlight. After 10 years, the loss of light transmission is only 6%, and the loss of light transmission of polyvinyl chloride (PVC) panels is as high as 15%. ~20%, glass fiber is 12%~20%. The impact strength of PC board is 250~300 times that of ordinary glass, 30 times that of acrylic sheet of the same thickness, and 2~20 times that of tempered glass. There are “not broken glass” and The reputation of “Sound Steel”. At the same time, the specific gravity is only half of that of glass, saving the cost of transportation, handling, installation and supporting frame. Therefore, PC boards are mainly used in fields that have high requirements for both light transmittance and impact, such as greenhouses, outdoor light boxes, shields, etc.
One side of the sun panel is coated with an anti-ultraviolet (UV) coating, and the other side is treated with anti-condensation. It integrates anti-ultraviolet, heat-insulation and anti-drip functions. It can block ultraviolet rays from passing through. It is suitable for protecting valuable artworks and exhibits. Damaged by ultraviolet rays: There are also PC boards made with a double-sided UV special process, which is suitable for special flower planting and environments with higher requirements for anti-ultraviolet protection. Confirmed by the national standard GB50222-95, the sunshine board is flame-retardant grade one, that is, grade B1. The ignition point of the PC board is 580℃, and it will self-extinguish after leaving the fire. It will not produce toxic gas during combustion and will not promote the spread of the fire.
Sunshine panels have gradually become one of the main fireproof materials for large-scale daylighting buildings. And according to the design drawing, cold bending method can be adopted on the construction site to install arched, semi-circular roof and windows. The minimum bending radius is 175 times the thickness of the adopted plate, and hot bending is also possible. In fields such as greenhouses and architectural decorations with curved designs, the strong plasticity of PC boards has been widely used.
The sound insulation effect of solar panels is obvious, and it has better sound insulation than glass and acrylic panels of the same thickness. Under the conditions of the same thickness, the sound insulation of greenhouses, greenhouse projects, greenhouse framework manufacturers, solar panels is 34dB higher than that of glass, which is international The material of choice for highway noise barriers. Keep cool in summer and keep warm in winter. PC board has lower thermal conductivity (K value) than ordinary glass and other plastics, and the heat insulation effect is 7% to 25% higher than that of glass of the same thickness. PC board heat insulation is as high as 49%. . Thus, the heat loss is greatly reduced. It is used in buildings with heating equipment and is an environmentally friendly material.
The sunshine board can maintain the stability of various physical indexes in the range of -40~120℃. No cold brittleness occurs at -40°C, no softening at 125°C, and its mechanical and mechanical properties have no obvious changes in harsh environments. The artificial weathering test is 4000h, the yellowing degree is 2, and the light transmittance reduction value is only 0.6%. When the outdoor temperature is 0°C, the indoor temperature is 23°C, and the indoor relative humidity is lower than 80%, there will be no condensation on the inner surface of the material.
Picture conclusion: When buying sun panels, you must keep your eyes open to prevent you from being filled with bad business routines. The last thing you lose is yourself. Good quality sun panels have a longer service life, and regular manufacturers will issue quality inspections. Report, sign a responsibility letter, and use high-quality solar panels with excellent performance to save man-hours without having to replace them every year. They are very suitable for long-term operation in greenhouses such as aquatic products, animal husbandry and flowers. Although the manufacturer’s warranty is 10 years, it has reached 15 in many areas. -20 years of records. It is equal to one investment and long-term benefit. That’s it for today’s sharing.
