乐彩网app是合法平台吗reasons for high-tech copper-steel coated vacuum tube

乐彩网app是合法平台吗the high-tech copper-steel coated vacuum tube can absorb heat efficiently. the absorption ratio of solar absorbing coating is more than 0.95; the emission ratio of solar absorbing coating is less than 0.06; and the glass tube coating has an adhesive layer, which makes the coating more firm and improves the absorption efficiency by 12% compared with the ordinary vacuum tube. double layer 3.3 high borosilicate glass tube is used to make the layer. after processing, the vacuum in the interlayer is less than 3.0*10-2 pa. the thermal expansion coefficient is small. the emission ratio of al-cu-cu film layer is lower than that of pure copper mirror in the lower layer. the heat loss is lower. the absorption layer contains al_3n. the interference between the high temperature and anti-aging films increases the absorption ratio to 98% emission ratio drop due to the different metal composition and thickness of the film layer. as low as 4%, the absorption of heat is greatly increased.
