As usual, permeable bricks, Dutch bricks, etc. are used in major parks, greenways, squares and other places. Why are they so popular with everyone? Then you have to talk about their functions!
1. Turn waste into treasure with low raw material cost. The raw materials used are various waste ceramics and quartz sand. Square brick waste is used as the fabric of permeable bricks. The bottom material can be used from our ceramic waste products and collected from other manufacturers at low prices. In this way, the waste products of the factory products are digested in situ and converted into qualified products of another product, forming a closed product consumption chain. In this way, the cost of the product is reduced and the economic benefits are improved.
2. The product has very strong water permeability and water retention. The water permeability can reach more than 5mm / s, and its water retention can reach more than 12l / m2. Due to its good water permeability and water retention, the rainwater will automatically penetrate the bottom of the brick to the ground when it rains, and a part of the water is stored in the brick. Rainwater does not flow around like it does on a concrete road, and finally flows into the river intact through the sewer. When the weather is fine, the water that has penetrated under the bricks or stored in the bricks will evaporate into the atmosphere, playing a role in conditioning the humidity of the air, reducing the atmospheric temperature, and eliminating the city's "heat island".
3. Its excellent water permeability and water retention are derived from the porosity of about 20% of the product. With such a large porosity, ordinary people wonder if its strength is as small as lightweight refractory bricks. In fact, the strength of this product can reach more than 90kgf / cm2. When it is laid in a parking lot, it can overload cars with a load of more than 10t . In foreign countries, such as Japan, urban sidewalks, pedestrian streets, apartment parking lots, and airports are basically replaced by cement and stone hardened pavements. Why does this product have such great strength? One is that the thickness of the product reaches 60-80mm, the other is that the product participates in special release agents when blending the ingredients, and the third is that the product has been fired at a temperature of about 1200 ° C. The permeable brick of Guangzhou Wanxin Ecological Ceramics Co., Ltd. uses electromagnetic as the raw material, and its firing temperature reaches about 1230 ℃ -1250 ℃, and the firing cycle is about 20 hours. Therefore, although the porosity of the product is large, the strength is still guaranteed.
4. The product has significant economic benefits and the market is very broad. Because of its low-cost raw materials and few consumer manufacturers (the manufacturers that once controlled the consumer technology of the product, the products have been put on the market, and have been recognized by the market need only Guangzhou Wanxin Ecological Ceramics Company and Foshan Wanxin Ceramics Company), It has good water permeability, air permeability, water retention, temperature reduction, noise reduction, climate conditioning, elimination of the city's "heat island effect", multiple functions of improving air quality, and insisting on surface water circulation. The raw materials used are industrial ceramic residues such as waste ceramics, which change waste into Treasure is an important method to dispose of waste residue, one of the "three wastes" of the ceramic industry. Therefore, it has good environmental protection benefits and has received preferential support from government policies. Its price currently reaches 200 yuan / square meter in China, and around 400 yuan / square meter in Hong Kong and Japan. (Data and prices are for reference only.
