Greenhouses with polycarbonate sheets have a longer service life than traditional film greenhouses, have better thermal insulation, and are more suitable for growing crops. At the same time, greenhouses with hollow polycarbonate sheets are cheaper to build than glass greenhouses and are safer. Therefore, greenhouses with polycarbonate panels are gradually becoming the first choice for greenhouses. mainstream. So, what conditions should special hollow polycarbonate sheets for greenhouses meet? Special polycarbonate sheets for greenhouses generally have higher requirements. 1. Using 100% imported new PC raw materials to produce new imported polycarbonate raw materials can ensure the physical properties of the hollow polycarbonate sheets, including the light transmittance, impact resistance, light weight, and flame retardancy of the polycarbonate sheets. , sound insulation, weather resistance and other advantages. The above advantages of PC polycarbonate sheets are all based on the new PC raw materials used to produce polycarbonate sheets. Only hollow polycarbonate sheets produced with new PC raw materials will have these advantages. Are all the raw materials used? Brand new materials are the fundamental guarantee for the quality of polycarbonate sheets.
It is well known that the surface of polycarbonate sheets is covered with UV coating. The weathering reaction of objects is inseparable from the direct radiation damage of ultraviolet rays in the sun. This causes the yellowing and weathering of hollow polycarbonate sheets. The UV coating on the surface of polycarbonate sheets can effectively resist ultraviolet radiation damage. It is measured by the UV layer that is damaged by ultraviolet rays at 5μ per year. If the surface of polycarbonate panels is co-extruded and covered with 50μUV coating, the service life of the hollow polycarbonate sheets can be guaranteed to be 10 years.
As an ideal thermal insulation material, anti-fog functional polycarbonate sheets are often used in sun rooms and greenhouses. However, in foggy weather, due to the surface tension of the polycarbonate sheets, the fog will form small water droplets on the surface of the panel, which will be adsorbed on the surface of the panel. As the small water droplets continue to condense, fog droplets will be formed.
This will not only cause damage to the sheet, but will also have certain adverse effects on the indoors, such as reducing the light transmittance of the board and increasing indoor humidity. Therefore, in order to prevent this problem from occurring, it is necessary to install the polycarbonate panel during the production process. The surface is coated with an anti-fog coating, which can be combined with special materials on the surface of the board to reduce the tension between the fog droplets and the sheet, so that they can flow directly down the surface of the sheet, which plays a great role in protecting the polycarbonate sheet. It has a good protective effect and can also correspondingly extend the service life of the hollow polycarbonate sheet. The above are some special requirements for special polycarbonate sheets for greenhouse.
SINHAI Polycarbonate sheet Company has a patented product – a special sheet for greenhouses, which can absorb light that crops don’t like and only inject light that is beneficial to crops. Make crops grow better and produce higher yields.
