| Abstract:The dispersion performances of polyolefin long-fiber suspension were investigated by changing the suspension consistency, fiber disintegration time and application of various surfactants. Based on sedimentation volume method, fiber suspension observation and testing of the properties of resultant paper suitable pulp concentration and fiber disintegration time as well as a suitable surface surfactant were identified. The results showed that, when the pulp consistency was 0.04%, disintegration time was 2 mins, the dispersion of the long fibers could meet the basic requirements. The 4%concentration of AESA solution had better dispersive performance than that of SDS thanks to its lower surface tension. The paper formation, pore size, and the tensile strength of the sheet were better compared to the application of SDS. Its tensile index was 37.5 N·m/g, pore size of paper mainly distributed in 15～25 μm. |
