摘　　要：采用离心成型工艺,以1#纤维、2#纤维、3#纤维、骨料、硅溶胶、氧化铝为主要原料,制备成耐高温复合滤筒。研究了原料配比、离心转速、不同纤维和工艺参数对复合滤筒性能的影响。结果表明:按离心转速为1000 r/min,纤维和粉料的质量比为1∶1.5,布料速度为0.6 m/s,纤维比克值接近210 mL(5 g),在150℃烘箱固化12 h,可获得表层致密性更高、层状结构明显、纤维分布更均匀、内外壁平整的复合滤筒,其C环抗压强度达到0.581 MPa,气孔率达到80.7%,压降为553 Pa。High temperature resistant composite filter cartridges were prepared using centrifugal molding technology,with 1#fiber,2#fiber,3#fiber,aggregate,silica sol,and alumina as the main raw materials.By studying the effects of raw material ratio,centrifugal speed,different fibers,and process parameters on the performance of composite filter cartridges.The results show that at a centrifugal speed of 1000 r/min,the mass ratio of fiber to powder is 1:1.5,the fabric speed is 0.6m/s,and the fiber specific weight is close to 210ml(5g).After curing in a 150℃oven for 12 hours,a composite filter cartridge with higher surface density,obvious layered structure,more uniform fiber distribution,and flat inner and outer walls can be obtained.Its C-ring compressive strength reaches 0.581Mpa,porosity reaches 80.7%,and pressure drop is 553Pa.
