Why does PC board keep warm
1. PC board has good thermal insulation properties. The main reasons are as follows: Material characteristics PC board, namely polycarbonate board, has high thermal stability due to its special molecular structure. This material has a low thermal conductivity, which means that heat energy is difficult to transfer through the PC board. Therefore, the PC board can effectively prevent the impact of temperature changes in the external environment on the interior, thereby playing a role in thermal insulation.
2. Under normal circumstances, PC boards on the construction site need to be externally insulated. External insulation can improve the insulation performance of buildings, reduce energy consumption, improve indoor comfort, and can extend the service life of buildings. At the same time, external insulation can also improve the fire resistance and earthquake resistance of buildings. Therefore, it is recommended to carry out external insulation treatment on the construction site.
3. PC boards have low thermal conductivity and good thermal insulation performance. The small coefficient of linear expansion makes the expansion difference of the plate in different directions small. Energy-saving performance and anti-fog performance: PC solar panels have lower thermal conductivity, which greatly reduces heat loss and achieves the purpose of energy conservation and consumption reduction.
4. Light transmittance: The light transmittance of the two is similar, but the PC solar panel has high permeability and no haze; the FRP solar panel has relatively poor permeability and large haze. Thermal insulation: PC board has better thermal insulation than FRP board, especially the hollow structure of PC sun board makes its overall thermal insulation better. Temperature adaptability: PC boards have stable performance within the range of-40℃ to 120℃; although FRP boards have the same service temperature range, they will soften and deform at 50℃ in actual use.
5. As the best impact resistance material among thermoplastics, PC sheet has stable performance at high temperatures and is not easy to undergo qualitative change or stress relaxation. This means that the sun panels made of PC can withstand various severe weather conditions and ensure the stability and safety of the greenhouse. In addition to the above advantages, PC sheets also have excellent heat and sound insulation properties. Its linear expansion coefficient is small and its thermal conductivity is much lower than that of ordinary glass and other synthetic resins. It is a material with good thermal insulation properties.
6. Polycarbonate board is a thermoplastic engineering plastic with transparent characteristics, with excellent performance and wide applications. The following are its main characteristics and advantages: High light transmission: PC boards have a visible light transmission rate of up to 90%, and their light transmission performance is comparable to that of glass, and UV-treated PC boards can effectively prevent ultraviolet damage.
The difference between frp and pc board
1. There are significant differences between FRP boards and PC boards in material composition, performance characteristics and application scenarios. Material composition: FRP (Glass Fiber Reinforced Polyester) board is mainly composed of upper film, unsaturated resin and glass fiber. It is commonly known as glass fiber reinforced plastic, also known as transparent tile. PC (polycarbonate) board uses polycarbonate as the main component and is processed using co-extrusion technology. PC sunshine board is a polycarbonate hollow board with a hollow structure.
2. Differences in durability and weather resistance: PC boards have better ultraviolet resistance (usually with UV coating), while FRP boards may cause resin aging after long-term exposure and require regular maintenance. Service life: The service life of high-quality PC boards is about 10-15 years, and FRP boards can reach more than 20 years (protective paint needs to be applied regularly). FRP plates are recommended for applicable scenarios: chemical plant roofs, anti-corrosion enclosures, high-intensity lighting wells and other scenarios that require corrosion resistance + high load bearing.
3. FRP boards are stronger than PC boards, but the specific choice needs to be determined based on the use scenarios and needs. Strength contrast impact resistance: The impact strength of PC board (polycarbonate) is 250 times that of ordinary glass, but FRP (glass fiber reinforced plastic) has higher impact resistance due to its fiber-reinforced structure and is suitable for high-load environments. Compression/bending resistance: Due to the glass fiber lamination process, FRP plates have a better load-bearing capacity than PC plates and are not easy to deform under long-term load.
Analysis of the advantages and disadvantages of PC solar board solar greenhouse
1. Improved durability: PC sun panels have strong impact resistance and can withstand extreme weather such as hail and strong winds; their service life is as long as 3-10 years (imported materials can be longer), far exceeding the one-year replacement cycle of films, reducing long-term maintenance costs. Outstanding disaster resistance: PC sun panels are not easy to damage, which can avoid damage to crops in the shed caused by damage to the covering materials and reduce economic losses in extreme weather.
2. Vegetable greenhouses are mainly divided into six categories: solar greenhouses, plastic arch greenhouses, multi-span greenhouses, glass greenhouses, solar panel greenhouses and new material greenhouses. The selection needs to be considered in conjunction with climate, crop demand and cost budget. The structural material of solar greenhouse (single slope greenhouse) is mainly earth wall or brick wall, the top is covered with plastic film or insulation quilt, and a thick wall is set on the north side for heat storage.
3. Sightseeing greenhouse function: It integrates sightseeing, leisure and entertainment, and belongs to a new agricultural landscape form.
4. Although solar greenhouses and greenhouses are both facilities that create a suitable growth environment for crops, there are significant differences between the two in terms of structure, use, function and management. Solar greenhouse is a fixed building that mainly uses lighting and uses solar energy to maintain temperature. The skeleton of solar greenhouses usually adopts steel structure, aluminum alloy or wood structure, with strong bearing capacity, large span and stable structure.
Which insulation is made between glass and pc board
To sum up, glass performs better than PC boards in terms of insulation. If you need to consider the insulation effect, glass is a more suitable choice.
The difference between the thermal insulation coefficient of pc board and glass is 1%. Ordinary glass greenhouses have excellent light transmittance, about 90%, while the highest light transmittance of PC solar panels can reach 89%, which is almost the same as glass. A high enough light transmittance allows both to ensure that plants in the greenhouse enjoy sufficient light.
Glass greenhouses have poor insulation performance and require additional heating in winter. The energy consumption is more than 50% higher than that of solar panel greenhouses, and long-term operating costs increase significantly.
PC endurance board has excellent impact resistance. Its impact strength is 30 times that of tempered glass and is not easy to break. If you choose a double-layer PC endurance board, its insulation performance will be better. Even a single-layer PC board has a low heat transfer coefficient and good heat insulation effect.
When choosing endurance board or glass, it needs to be decided based on the specific application scenario. Endurance boards, also known as PC endurance boards, are suitable for making canopies, industrial parts, etc. Endurance board has the characteristics of high light transmission, impact resistance, ultraviolet protection, light weight, flame retardant, good bending, sound insulation, energy saving and heat preservation.
Advantages and disadvantages of pc endurance board
High transparency: PC endurance boards have high transparency, allowing light to pass through and making the interior brighter. In addition, PC endurance boards also have excellent weather resistance, impact resistance and heat resistance. They can withstand extreme weather and strong impact forces, and are not easy to deform, crack or discolor. Therefore, PC endurance boards are widely used in buildings, billboards, stations, airports, sports venues, swimming pools, greenhouses and other fields.
PC endurance boards have many advantages, but they also have certain disadvantages. Advantages mainly include: strong durability: can withstand strong impact and pressure, and is not easy to rupture and deform.
Excellent flame retardant performance: The first-class refractory material, i.e. B1, has its own ignition point as high as 580 ° C. It self-extinguishes after leaving the fire, and will not help the spread of fire. Easy processing and forming: It can be processed by thermoforming, stamping, cutting and other methods to adapt to various complex shapes and design requirements. Disadvantages: Higher price: Compared with ordinary plastic plates, the manufacturing cost and selling price of PC endurance plates are relatively high.
The advantages and disadvantages of PC endurance boards are as follows: Advantages: Strong durability: It can withstand strong impact and pressure, and is not easy to rupture or deform. At the same time, it has excellent weather resistance and chemical resistance, can resist the erosion of chemical substances such as ultraviolet rays, acid and alkali, and is not easy to age and discolor. High transparency: It can let light pass through and make the interior brighter. The transparency can reach the level of glass.
The price of real PC endurance boards is usually higher than that of boards produced using recycled materials. At the same thickness, the price of new PC boards is about 5 times that of new PET boards, and slightly lower than PETG boards. The price of recycled PC endurance boards may be 30%-50% lower than the normal price, but the quality is poor and it is not recommended for use in high-demand scenarios. The difference between PC endurance boards and other plates Endurance boards are solid boards, and hollow sunshine boards are not endurance boards.
