高温除尘用微粉SiC多孔陶瓷的制备和性能研究
Preparation and Properties Study of SiC Porous Ceramic for Purifying High Temperature Dusty Gas
摘要
Abstract
The paper takes SiC particles whose mean grain size is 2. 4 μm as the main raw materials, activated carbon and graphite as pore former, and adds ceramic binder and Sodium carboxymethyl cellulose (CMC) solution, mixed to shape with the coated process step by step. It sinters the embryo body after forming into porous ceramics which has different ceramic binder content (5-15wt%) an different forming pressure (5-20 MPa) in 1300 ℃ , and discusses the changes of the porosity rate, shrinkage rate, filter pressure drop and compressive strength over the different ceramic binder content and different forming pressure. The research show that the porosity rate of porous ceramics reduced gradually while the forming pressure increases to 48. 8 MPa from 12. 2 MPa and binder content increases to 15% from 5% , and the compressive strength increases while the forming pressure of the embryo body and the binder content increases. The embryos body shrinkage rate after sintering tias a tendency to increase after a first decreases. When the binder content was 10% and the forming pressure is 19. 52 MPa, the compressive strength and show porosity of the porous ceramics are made of high value, 31.75 MPa and 29.87% respectively,when the air flow is 0. 016 m3·h-1 at room temperature, filter pressure drop is 21.23 hPa.关键词
