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.

The development of the Leisuwash SG had one principle: a brushless machine should still deliver a great wash result ! The combined chemical applicator and high pressure bar do make this possible. It keeps an even distance to the car so that the chemicals can reach all parts of the vehicle in the same concentration. The combination of different chemicals will soften up even persistent dirt and the contouring high pressure system will clean it off easily.
