China Drying Network The European POLYSOL R&D team, which is funded by the European Union's seventh R&D framework program and participated in by several member states, recently developed an all-polymer solar collector. Due to the lower raw material prices and production process costs of the polymer, the study is expected to significantly reduce the initial capital investment for solar collectors.
The design concept of the all-polymer solar thermal collector complies with the EU's strategic requirements for reducing dependence on fossil fuels and promoting environmental protection, and the cost is low. At present, it has entered the stage of commercial development.
According to reports, the main achievements of the POLYSOL research team are: First, the use of polycarbonate as a polymer solar light absorption material, through repeated tests to confirm the two polymers as the heat sink adsorption chamber, its performance is better than ABS; Second, the successful development Selective physical vapor deposition (PVD) coating technology applied to polymer sorbents. The coating technology has high heat-resistant temperature and high thermal conductivity. The third is 85% coating material source. Regeneration of mixed waste polymers will greatly reduce production costs. Fourth, three different types of heat-absorbing and conducting channels are designed to meet the pressure drop and heat transfer performance requirements. Fifth, the contour design of the device is optimized to directly increase its production. Assembly speed, simplicity, and related costs.
The European Union is the world leader in solar heating technology, but due to high early capital investment, the sales and use of related products are not ideal. For this reason, EU scientists hope to develop solar collectors with lower cost and increase their market usage.
Recovery straps and tow straps are sometimes used interchangeably, but it's important to note that both cannot be used for the same purposes. The main difference between a towing strap and a recovery strap is the fabric and its ability to stretch. These straps are made of a nylon fabrication so they can stretch. A vehicle tow strap is usually made of polyester which stretches less than nylon. A tow strap does just that: tows a vehicle behind another. You'll generally find a tow strap with hooks on each end. Traditional tow straps and chains are similar in their towing applications.
