Hollow brick prepared based on recycled foundry waste sand and preparation method thereof
The invention discloses a hollow brick prepared based on recycled foundry waste sand and a preparation method of the hollow brick, and belongs to the technical field of foundry waste sand recycling. The invention discloses a hollow brick prepared based on recycled foundry waste sand and a preparation method thereof, and the hollow brick is prepared from the following raw materials in parts by weight: 35-55 parts of foundry waste sand, 20-35 parts of silicate cement, 10-15 parts of glass fiber, 10-12 parts of fly ash, 9-12 parts of aluminum oxide, 5-6 parts of aluminum hydroxide, 5-6 parts of quick lime and 3-6 parts of a coloring agent. In order to solve the problem that the whole production line is greatly limited due to the facts that existing casting waste sand is various in variety, and different types of waste sand cannot be effectively treated at the same time through a single recycling process, the types of the casting waste sand are distinguished; corresponding recycling technology, regeneration technology and resource utilization technology can be provided for different types of casting waste sand and dedusting ash.
本发明公开了一种基于回收铸造废砂制备的空心砖及其制备方法，属于铸造废砂回收技术领域。基于回收铸造废砂制备的空心砖及其制备方法，由以下重量份的原料制成，铸造废砂35—55份、硅盐水泥20—35份、玻璃纤维10—15份、粉煤灰10—12份、三氧化二铝9—12份、氢氧化铝5—6份、生石灰5—6份和着色剂3—6份。为解决现有的铸造废砂种类繁多，单一的回收工序无法同时针对不同种类的废砂进行有效的处理，从而导致整个生产线存在着较大的局限性的问题，通过对铸造废砂的种类进行区分，不同种类的铸造废砂和除尘灰可有相应的回用技术、再生技术和资源化利用技术。
