Preparation process of porous heat-insulating ceramic material
The invention discloses a preparation process of a porous heat-insulating ceramic material. The preparation process is characterized by comprising the following steps: premixing raw materials, grinding and stirring, performing spray granulation, presintering, sieving, mixing formed auxiliary materials, forming, sintering, and inspecting. The material uses a glue solution. The key point of the preparation process lies in that before a conventional forming procedure, a spray granulation method which is commonly used in ceramic dry pressing forming or powder metallurgy forming is used, a spherical particle structure body required by a porous material structure is obtained in advance, and the particle size is strict through optimized process parameter control and screen sieving. The preparation process has the beneficial effects that spherical particles are easy to sieve, the size uniformity is well controlled, the size of pores obtained through accumulation is uniform, and liquid leakage and blockage are not prone to occurring. Meanwhile, the particles are of a hollow structure, heat conduction channels are greatly reduced, the good heat insulation performance is achieved, the atomization efficiency is greatly improved, and long-time overheating denaturation of effective components of atomized liquid making contact with the atomizer is also avoided.
本发明公开了一种多孔隔热陶瓷材料的制备工艺，其特征在于包括以下步骤，原料预混，研磨搅拌，喷雾造粒，预烧结，过筛，形成辅料混合，成型，烧结，检验，胶液；本方案的关键点在于，在常规的成型工序之前，使用了常见于陶瓷干压成型或粉末冶金成型的喷雾造粒方法，预先得到多孔材料结构所需的球形颗粒结构体，并经过优化的工艺参数控制和筛网过筛，严格颗粒尺寸大小；有益效果在于这种在球形颗粒容易过筛，尺寸均匀性很好控制，堆积得到的孔隙大小均匀一致，不易漏液，也不易堵塞。同时颗粒具有中空结构，大大减少了导热通道，具有非常好的隔热性能，大大提高了雾化效率，也避免了与雾化器接触的雾化液的有效成分长时间过热变性。
