酚醛树脂对高软化点沥青的发泡行为及生物挂膜性能的影响
Effects of Phenolic Resin on the Foaming Behavior and Biofilm Biomass of High Softening Point Pitch
摘要
Abstract
Carbon foams were synthesized by self-foaming method derived from high softening point pitch as packing media in biological aerated filter system.To achieve a high biofilm biomass,phenolic resin was added into the high softening point pitch to improve the open porosity of carbon foam.When the additive mass fraction of phenolic resin is 30%,the open porosity and mass fraction of biofilm biomass of the resultant carbon foam are 100% and 5.4%,respectively.When the additive mass fraction of phenolic resin is 40%,the carbon foam has a high compressive strength of 5.2 MPa accompanied with a low open porosity and a poor uniformity of pore structure.关键词
