How much water permeable brick absorbs, compared with ordinary bricks
Energy-saving lamps, permeable bricks , and equipment for recycling waste water ... On September 5th, the large-scale theme popular science exhibition of "Energy Conservation and Environmental Protection" sponsored by the China Association for Science and Technology and sponsored by the China Quality Association and the Guangzhou Science and Technology Association and high-efficiency energy-saving products The national tour exhibition opened in Nanjing Science and Technology Museum. This exhibition will continue to October 8. After all, how energy-efficient is an energy-saving lamp? In the exhibition hall, an energy-saving lamp and a general lamp electricity comparison device attracted many visitors. The reporter saw that a 36W energy-saving lamp and a 100W general incandescent lamp, under the condition of equal voltage (220V), when the luminous intensity of both are 20UA, the energy-saving lamp looks much brighter, and at this time The current of the energy-saving lamp is only about 0.08A, and the general lamp is 0.26A. Another type of LED lamp (semiconductor lamp) has better energy saving effect. Manually swinging the power generation equipment can easily make a row of LED lights light up. "LED lamps consume only one-tenth the power of incandescent lamps." The staff said that this newly developed semiconductor lamp is the most energy-efficient lamp available today, and its life span can be extended 100 times compared to ordinary incandescent lamps. There is another "contrast" that is equally remarkable, and that is Permeable bricks and ordinary cement bricks who are more absorbent. There is not much difference in appearance between the two bricks, but when they are drenched with water, the water can quickly penetrate. "This is very representative information on environmental protection and energy saving." Staff leaked that the permeable brick is a kind of highly permeable pavement information. When it rains, the permeable brick can directly put rainwater into the soil and reduce the water in the road area to avoid it. Water is lost and groundwater is made up for rainwater collection and reuse.
