Preparation method of high-porosity particle catcher
The invention relates to a preparation method of a high-porosity particle catcher, which comprises the following steps: mixing 10-60% of a starch pore-forming material, 0.1-30% of an organic matter pellet pore-forming material and 5-30% of a carbon source pore-forming material to form a pore-forming material; mixing 40-45% of talc, 10-20% of kaolin, 20-30% of aluminum oxide and 10-15% of silicon oxide to form an inorganic raw material; mixing the inorganic raw materials and the pore-forming material according to a ratio of 10:2-5, adding 6-10% of a binder and 1-2% of a lubricant, adding 20-30%of water, and fully stirring all the components; extruding the mixture through an extruder; carrying out drying treatment on the honeycomb ceramic blank through a drying machine; putting the dried honeycomb ceramic blank into a sintering furnace, gradually raising the temperature from room temperature to 1420 DEG C in a manner of raising the temperature at 30 DEG C per hour and then keeping the temperature at 1420 DEG C for 8 hours. According to the invention, a ternary pore-forming material system is utilized, the requirement for high porosity is met, heat accumulation during sintering is reduced through a method of staggering heating peaks, and therefore sintering cracking is reduced.
本发明涉及一种高孔隙率颗粒捕捉器制备方法,采用下述步骤制成:采用淀粉类造孔材10‑60%、有机物小球造孔材0.1‑30%、碳源造孔材5‑30%,混合形成造孔材;采用滑石40‑45%、高岭土10‑20%、氧化铝20‑30%和氧化硅10‑15%混合,形成无机原料;然后按照无机原料与造孔材比例10:2‑5的比例混合,并且加入粘结剂6‑10%和润滑剂1‑2%份,再加入水20‑30%份充分搅拌;采用上述物料通过挤出机挤出物料;将蜂窝陶瓷胚体通过干燥机进行干燥处理;将干燥后的蜂窝陶瓷胚体放入烧结炉内,温度为从室温逐步上升至1420℃,按照每小时30℃进行升温,然后在1420℃恒温8小时。利用三元造孔材系统,既达到高孔隙率的需求,又通过错开发热峰的方法,降低烧结时的热量积累,从而减少烧结开裂的发生。
