Method for preparing foamed ceramic from ceramic production waste
The invention relates to the field of ceramic material production, in particular to a method for preparing foamed ceramic from ceramic production waste. The method comprises the following steps: 1, batching: a high-temperature foaming agent is added into well-known ceramic production waste serving as a main raw material to prepare a foamed ceramic raw material; 2, material distributing and firing: the prepared raw material is subjected to punch forming or directly scattered in refractory kiln furniture to be fired in a kiln, the firing stage is provided with a transition cooling section, the transition cooling section is located between a firing section and a quenching section, the temperature range is from the highest firing temperature to 1000 DEG C, and the cooling rate of the transition cooling section is 2-8 DEG C/min; and 3, polishing and cutting: a foamed ceramic blank obtained after firing in the step 2 is subjected to polishing and cutting treatment to obtain the required foamed ceramic product. Compared with the prior art, the scheme can ensure that the foamed ceramic has high quality and high-quality product rate while a large amount of ceramic production waste materials are utilized.
本发明涉及陶瓷材料生产领域，具体为一种使用陶瓷生产废料制备发泡陶瓷的方法。此方法包括如下步骤：包括如下步骤：步骤1：配料；以公知的陶瓷生产废料为主要原料，添加高温发泡剂制成发泡陶瓷原料；步骤2：布料烧成，将配好的原料冲压成型或直接布撒在耐火窑具内入窑炉烧成；烧成阶段设有过渡降温段，过渡降温段位于烧成段和急冷段之间，其温度区间为最高烧成温度～1000℃,过渡降温段的降温速率为2℃～8℃/min;步骤3：抛磨切割，经步骤2烧成后获得的发泡陶瓷毛坯经过抛磨切割处理获得所需发泡陶瓷产品。和现有技术相比，本方案可在大量利用陶瓷生产废料的同时也保证发泡陶瓷具有较高的品质和优等品率。
