Anyone who is engaged in greenhouse cultivation probably knows that the most important thing when growing vegetables in a greenhouse must be temperature. So is there a material that has better thermal insulation performance than other covering materials such as glass and film? Well, of course there is. Speaking of this, what I have to mention is the hollow polycarbonate sheet. I will explain it to you in detail below.
Greenhouse PC material polycarbonate hollow sheet are currently widely used in the greenhouse industry as a new type of decorative material with high strength, high light transmittance, sound insulation and noise reduction, energy saving and environmental protection. The hollow polycarbonate sheet covering material is used to build the lighting, insulation and heat storage effect of the greenhouse. It is better, has good wind resistance, has a longer service life, and has lower maintenance costs in the future.
1、Commonly used specifications in the greenhouse industry:
Product Name:hollow polycarbonate sheet
Type:Twin wall polycarbonate sheet,Multiwall polycarbonate sheet
Warranty:10-Year
Thickness:4mm,6mm,8mm,10,,12mm,14mm,16mm,(Other thicknesses can be customized)
Size:1220*2440mm,2100*5800mm,2100*6000mm
Color: clear, lake blue, grass green, brown, milky white (other colors can be customized)
2、What are the advantages of using it as greenhouse covering:
①Light transmittance: polycarbonate hollow sheet use imported raw materials, which make the hollow polycarbonate sheet perform well in terms of UV resistance, lighting, and anti-fog and Prevent yellow. (The light transmission loss of PC polycarbonate hollow sheet after 10 years is only 10%, while the loss rate of PVC is 15% higher, and that of glass fiber is 12%-20%.
② Light weight: The weight of polycarbonate hollow sheet is about half that of glass of the same thickness, saving the cost of transportation, removal, installation and support frames.
③Flame retardant and self-extinguishing: In line with the national standard GB86242006 certification, Polycarbonate hollow sheets are flame retardant Class B, and the PC panel’s own ignition point is 580°C and will automatically extinguish after leaving the fire. It will not contribute to the spread of the fire, nor will it produce toxic gases. It is Green and environmentally friendly new materials.
④Easy to process and install:polycarbonate hollow panels can be cold-bent at the construction site according to the design drawings, and installed into an arch, semi-circular top or round arch.
⑤Sound insulation and noise reduction: PC hollow panels have obvious sound insulation effect and have better sound insulation than glass and acrylic panels of the same thickness. Under the same thickness, the sound insulation of PC hollow sheets is higher than that of glass. It is the most popular in the market. 5 is a common material for highway noise barriers.
⑥Thermal insulation: Keep cool in summer and keep warm in winter.Polycarbonate hollow sheets have a lower thermal conductivity (K value) than ordinary glass and other plastics, and the thermal insulation effect is higher than that of the same glass, thus greatly reducing heat loss. It is an environmentally friendly material for projects with heating equipment and greenhouses.
⑦Wide temperature adaptability range:hollow polycarbonate sheet have no significant change in physical properties within the temperature range of -40°C to 125°C;
⑧Strong weather resistance: after 4,000 hours of artificial aging test of the hollow polycarbonate sheet, the yellowing degree was 2, and the light transmittance reduction value was only 0.6%.
⑨ Anti-condensation: When the outdoor temperature is 0℃, the indoor temperature is 2℃, and the indoor relative humidity is lower than 80%, there will be no condensation on the inner surface of the material. The dew will flow away along the surface of the sheet and will not drip indoors. Maintain good light transmittance.
⑩Green and environmentally friendly:hollow polycarbonate sheet are non-toxic, odorless and radiation-free, and are modern new green and environmentally friendly building materials.
3、Polycarbonate hollow sheet greenhouse application:
With the development of polycarbonate sheet greenhouses in recent years, the scope of application has become wider and wider. It is not only used for traditional planting, but also used in seedling cultivation, exhibition greenhouses, agricultural carnival greenhouses, ecological restaurant greenhouses, etc. It is also widely used in planting, tourism, and processing industries.
