Performance principle of ceramic ecological permeable brick and its use effect
At present, in urban development, excessive and disorderly use of groundwater resources constitutes a decline in groundwater levels; but when heavy rain is approaching, rainwater resources are not used well, which constitutes the two extremes of waterlogging and groundwater resources shortage. Effective backflow and recharge of groundwater resources have become an inevitable trend in urban development today. Ceramic permeable bricks , this kind of product that uses solid waste resources to return to the ground for the second time came into being. Ecological ceramic permeable bricks use high-temperature porcelainized ceramic melt-wrapping process. At the same time as the ceramic body is ceramicized, a honeycomb multi-particulate structure is produced to ensure high strength and water-permeability uniformity, and to enhance the stability of product performance. .
The ceramic permeable bricks are made of discarded ceramics, which are ground, screened, finely screened, self-dosed, and a 16,000-ton press twice to form the cloth once to ensure the strength and structural stability of the product. Although the brick itself is under high pressure, it has small holes, which reserves pores for rainy days or flooding into the ground. It effectively addresses the lack of water permeability of urban paving stones, alleviates the decline of urban groundwater levels, and is useful to avoid the ground. Downward trend. The ecological ceramic permeable bricks fired at high temperature, the rainwater penetrates into the ground through layers of filtration, and no harmful substances will occur, which is useful to ensure the safety of groundwater.
Ceramic permeable brick
The permeability of ecological ceramic permeable bricks is good, so what is the principle? How can we effectively protect the water permeable effect of ceramic permeable bricks for long-term usefulness? Wanxin Xiaobian reveals the secrets of ecological ceramic permeable bricks for you.
Due to the large amount of impervious materials such as concrete, asphalt, stone, etc., and the large increase in fuel consumption equipment, heat absorption cannot be performed on the ground, and heat is stagnated inside the city to form a heat island effect. At the same time, when the heavy rain is coming, imperfections such as ditches, sewers, and grounds lead to water in the road area and rainwater is drained away, which cannot help to relieve the groundwater. Even if it rains, the city after the rain is no doubt Become a "steamer." The current city needs to upgrade the drainage system, and it is also necessary to continuously improve the condition of the road surface to return the water to the "source".
Urban roads have serious water accumulation and cannot quickly infiltrate rainwater into the ground, resulting in waterlogging
The phenomenon of weathering and weathering of cement permeable bricks and the double-layer structure of permeable bricks have a large correlation with the expansion coefficient, which easily constitutes a delamination phenomenon.
Ecological ceramic permeable bricks have very high water retention characteristics. The porosity reaches 25%. Under a normal state of water retention, a 300 * 300 * 55mm brick can hold 0.98kg of water. When it rains, it absorbs and retains a large amount of water. Under the sun's rays, the water retained in the brick body and the bottom layer can transpiration and heat absorption, alleviating the heat island effect; it can also bring moisture to the surrounding plants. It is precisely based on the water retention of ecological ceramic permeable bricks that the road surface will not accumulate water and facilitate pedestrians to walk, and achieve "light rain without wet shoes, heavy rain without water", so in the construction of sponge cities, some road drainage equipment can be saved. Cut municipal construction costs.
Refinement of ceramic permeable bricks
The use of permeable bricks in gardens and squares changes with the season, and the space for collecting rainwater also changes. The garden in the dry season can effectively play a role in retaining water and alleviating the heat island effect. The rainwater collected by the beautification of the roof, the construction of the ecological stay area, and the permeable brick paving is collected in the garden-type reservoir, and becomes a pond for storing rainwater. It “replenishes” the groundwater resources. Reasonable planning can use rainwater resources to achieve green ecology The role of sponge cities.
Wanxin ceramic permeable bricks are scientifically and usefully paved, and can store more than 55k of water per square meter. Especially in the north where groundwater is scarce, the construction of permeable bricks on the ground should be strengthened to improve the use of groundwater resources.
