The core of the authentic reflective mold is electroformed on a needle-type electroformed motherboard with very high precision. This type of reflective mold is expensive, and some small companies in China do not invest enough funds to produce it. This also results in products that look like reflective foils, but actually aren't.
In order to make it easier for users to distinguish real reflective sheets from fake ones, our company has also specially developed a small flashlight for "reflective sheet identification". The detection method is to place the solar road stake. 10 meters away and hold a small flashlight, place the flashlight between your eyes, shine light on the surface of the product to see if it reflects light. The results are clear at a glance.
Solar water heater reflector
Thenumber of Ps reflectors is 174, the number of HCE absorption tubes is 58, and the overall optical efficiency is ≥48. Set by the solar power manufacturer, the parameters of the reflector are reflector number Ps 174, absorber tube HCE number 58, overall optical efficiency ≥ 48. The hollow reflector is the original component of the solar collector. Reflectors play an important role in improving the performance of solar collectors.
Nowadays, most solar water heaters are no longer equipped with reflectors. Reflectors are installed under the vacuum tubes to reflect light and increase the effective heat collection area. In actual use, the reflectors are easy to float and float. to flow. It has no reflection effect and easily blocks the wind, which is not conducive to safety, so it is basically not used now.
