Solar Water Heater Parts
Guangyuan company have the advanced production line of all-glass evacuated solar collector tube, product make use of Tsinghua University’s three target magnetron sputtering choose compound absorbing coatings film coating technology
The advantage of this production: high temperature and cold resistance, high thermal efficiency.
1. The vacuum tube material adopt high borosilicate 3.3 high hardness glass, it has advantages of durable and high light transmittance, it can bear the strike of steel ball fall off from 450mm height which have 300mm diameter, and after the vertical shock in the middle of vacuum tube, the tube also have no damage.
2. The vacuum tube has two layer of glass and high vacuum. Between the two layer, the gas pressure will less than or equal to 5.0x10-2pa.
3. Coating film use magnetron sputtering gradually change of selectivity of composite absorbing coatings, the light absorptivity of vacuum tube was greater than 93%, and emissivity less than 6.5%, high thermal efficiency, low heat waste , strong adhesion, ensure the permanent thermal.
4. The vacuum tube has excellent performance, will not explode in high temperature of 300 ° C conditions, not frost cracking when temperature below minus 30 ° C, and will not damaged after repeated impact by the cold and hot water which temperature between 0°C --90°C.
5. Strong ability of anti-aging, it will be used for 10-15 years when there have no damage by man-made.
