Problems solved by technology

[0002] With the development of the economy, the surface of modern cities is gradually covered by buildings and concrete and other materials, and the number of hardened road surfaces is gradually increasing; while traditional ground hardening materials are mainly stone, cement, ordinary ceramic square bricks, etc.; these materials are airtight It is impermeable, causing a lot of inconvenience and harm; when it rains, the rainwater will flow across the hardened ground, and the rainwater will take away a large amount of urban pollutants during the crossflow process, causing the pollution of rivers and lakes; In order to solve the above problems, there are more and more studies on permeable bricks, and economical and practical high-performance permeable bricks have become a research hotspot; and with the ceramic industry With the rapid development of the building ceramics industry, especially the rapid development of the building ceramics industry, the discarded ceramics are also increasing year by year, and the disposal of discarded ceramics has become an increasingly serious environmental problem; there are also some technologies that use ceramic waste to make permeable bricks, such as Pang Wei, etc. People disclosed "a ceramic permeable brick and its production method", which is made of waste wall and floor brick particles, feldspar powder, wood chips, etc., and fired at high temperature
Due to the variety of wall and floor tiles (porcelain and ceramic), there are certain shortcomings in the permeable bricks produced by this method, that is, in actual production, the preparation process is not easy to control due to the different raw materials used, and the performance of the product Large changes; at the same time, wood chips are used as pore-forming agents in the production process, which makes the production process more complicated, the effect of emptying is not obvious, and the firing temperature is relatively high (1300 ° C), so the production cost is relatively high

Abstract

The invention discloses a water-permeable ceramic waste brick and a production method thereof. The water-permeable ceramic waste brick comprises, by weight, 71-79% of ceramic wastes, 3-4% of clay, 8-13% of feldspar and 10-12% of water glass. The water-permeable brick product is obtained through burdening, crushing, mixing, molding, drying, sintering and heat insulation of all above components. The water-permeable brick produced in the invention has the advantages of low sintering temperature, simple production technology, high water-permeable intensity, excellent performances, and greenness and environmental protection.
