High-strength large-size fiber filter pipe and preparation method thereof
The invention discloses a high-strength large-size fiber filter tube and a preparation method thereof, and belongs to the technical field of flue gas dust removal and denitration integrated ceramic membranes. The formula is optimized and recombined for multiple times, a traditional extrusion mode is adopted, a product binder coating mode is kept, and a low-temperature sintering technology is adopted to ensure high bending strength of the product; the shrinkage resistance of the large-component green body in the firing process is effectively dispersed by utilizing the component force characteristics in mechanics in an inclined loading method, and the cracking phenomenon caused by large shrinkage resistance is avoided; the conditions of collapse and deformation of the product in the high-temperature softening process are effectively supported by a lining circular aluminum oxide sleeve loading method, and the roundness of a large component is guaranteed.
本发明公开了一种高强度大尺寸纤维过滤管及其制备方法，属于烟气除尘脱硝一体化陶瓷膜技术领域。本发明通过配方多次优化重组并采用传统挤出方式，保持产品粘结剂包覆方式，加低温烧结技术保证制品较高的抗弯强度；以倾斜式装载方法利用力学中分力特点，有效分散了大构件坯体在烧制过程中收缩阻力，避免了收缩阻力大带来的开裂现象；以内衬圆形氧化铝套管装载方法在有效支撑了制品在高温软化过程中塌陷、变形情况发生，保证了大构件圆整度。
