As people's requirements for building decoration materials are getting higher and higher, in order to meet the needs of consumers, the market has produced a variety of products, just like this beautiful and stylish, yet functional PC (polycarbonate) The ester) sun board is liked by people today. Following small to tell you about the advantages of PC sheet is what PC board material and greenhouses of what.
What is PC board material?
The polyvinyl chloride (PVC) color is slightly yellow translucent and shiny. The transparency is better than that of polyethylene and polypropylene, and worse than that of polystyrene. It is divided into soft and rigid polyvinyl chloride, and the soft products are soft and tough, and the stickiness of the hand is higher than that of the low density polyethylene. Less than polypropylene, whitening occurs at the inflection point. Common products: plates, pipes, soles, toys, doors and windows, wire jackets, stationery, etc. It is a polymer material that uses one chlorine atom to replace one hydrogen atom in polyethylene.
What are the advantages of PC board greenhouses?
1, light transmission, anti-ultraviolet
Most of the PC-board greenhouses use double-glazed transparent sun panels. If this double-glazed transparent solar panel is used, the lightness is important. The most important thing is that it has strong light transmission, and it is also conducive to plant growth. The most important thing is to be able to do it. There is no dead spot in the greenhouse, and the land utilization rate and lighting performance have been unprecedentedly improved. The important thing is that transparency will not be significantly reduced due to the use of time.
2, impact resistance, high temperature resistance
PC is the best one in the impact resistance of thermoplastics, so it is said that this kind of high temperature is still small in its potential deterioration and stress relaxation is also small. Sun panels made of PC have excellent impact resistance and are able to maintain stable performance over a wide range of temperatures (-40 to +120).
3, heat insulation, sound insulation performance
Linear expansion coefficient: One of the synthetic resins with a smaller coefficient of linear expansion. First of all, according to different directions of the plate, the coefficient of linear expansion is slightly different. Generally speaking, the average coefficient of expansion can reach 0.065mm/m. °C. The thermal conductivity of PC board is very different from that of synthetic resin. It is 1/4 of glass, 1/300. , 1/1000, 1/12000, so it is a material that is well-insulated.
4, energy-saving performance, anti-droplet performance
If the sun board can be said to have a lower thermal conductivity than other ordinary glass and other plastics, this will also greatly reduce the heat loss, so that it can achieve the purpose of saving energy and reducing consumption, so it is also an environmental protection material. . At the same time, it adopts German Bayer material anti-droplet technology, or high-tech infrared special treatment, evenly distributed on the lower surface of the high concentration coating, this can avoid the decline in transmittance caused by water mist, but also to avoid direct condensation Damage to plants and animals below when dripping vertically.
5, flame retardant, fire resistance
PC sunshine board has a good waterproof, it has been tested by the national fireproof building materials quality supervision and inspection center, according to the GB8624-1997 standard, so it can reach the flame retardant B1 level, and the sun board is under the strong flame burning, so that it will not The spread of long fires, the burning process of the sun board will not produce smoke, so that the harm to the human body is relatively small, this shows that it is a good flame-retardant properties, this material in the world advanced countries fire test is also very High evaluation.
Summary: What are the advantages of the PC sheet material and the advantages of the PC board greenhouse? Introduced to this, the advantages of the PC sheet are still relatively high. The most important thing is that this material is particularly good in fire resistance, and it is in many countries. Get a high rating.
