Huang Ming gave it to you. In fact, it is confidential, but I am optimistic about your 100 points. If you don’t accept my answer, I will be angry, haha

2. Heat collecting components:
The product uses the latest patented product "UTLE" of Huangming Group Polar super cold tube
Technical indicators of vacuum tube:
1) Using interference film technology, the absorption rate can reach 96 and the scattering rate is less than 4.
2), the air-drying temperature is not lower than 400℃, and it is resistant to high cold -40 degrees.
3), the vacuum degree is lower than 5.0×10-4Pa.
4) The material is 3.3 high borosilicate glass, which can withstand the frontal impact of hailstones with a diameter of less than 2.5cm.
Using the world's most advanced vacuum tube coating technology - interference film technology, eliminating the traditional gradient film technology, three-target coating - aluminum, copper, stainless steel. Because the reflection curve of the traditional graded selective absorption film is not steep, the emission ratio increases with the temperature rise, resulting in a large increase in the emission ratio when working at 300-500°C. The interference absorption ultra-low emission ratio selective absorption film layer used in the "three high" tubes can solve the above contradiction. Since the two ceramic metal layers have appropriate metal volume ratios, mutual interference and the function of the reflective layer, It has a high solar absorption ratio and a low emission ratio. At the same time, the traditional gradient film is prone to deformation, drifting, failure and other phenomena at high temperatures of 300 to 400°C, seriously affecting the later heat collection effect, while the advanced interference film A similar situation will not occur because it uses three-target magnetic sputtering coating technology, an absorption layer, an anti-reflection layer and a metal layer. The three tubes improve the heat collection performance through interference and absorption of light waves. The metal layer is copper-plated, which is high temperature resistant, anti-aging, has good reflective properties, and can withstand air exposure temperatures of over 400°C. The heat gain can be increased by about 15% compared to water heaters of the same model. The heat collection capacity is extraordinary and it still has a certain heat collection effect in rainy weather. It is called the "Sun King".
