通过改变浆料纤维的配比,研究不同打浆度下吸液滤纸性能的变化,以期获得高质量的生物快检试纸用的低定量吸液滤纸。结果表明:在相同打浆度下,100%棉浆吸液滤纸的平均孔径最小,其最大孔径和平均孔径比较接近;配加针叶木丝光浆后平均孔径提高,配加20%针叶木丝光浆吸液滤纸在打浆度22～26°SR时可获得较均匀的孔径分布。100%棉浆吸液滤纸在200g·m-2定量下难以满足生物快检试纸的要求,配加20%～25%丝光浆并控制19～20°SR的打浆度可满足低定量吸液滤纸吸液性580～590g·m-2和厚度0.4mm的要求。
By changing the ratio of pulp fiber, the change of performance of filter paper under different beating degree was studied in order to obtain low-quality liquid-absorbing filter paper for high-quality bio-test paper. The results showed that the average pore diameter of the 100% cotton swab was the smallest under the same beating degree, and the maximum pore diameter and the average pore diameter were close to each other. The average pore diameter of the filter paper increased with the softwood softwood pulp added with 20% softwood pulp Liquid filter paper in the beating degree 22 ~ 26 ° SR can get more uniform pore size distribution. 100% cotton absorbent filter paper in the 200g · m-2 quantitative determination of bio-fast test paper is difficult to meet with 20% ~ 25% mercerized pulp and control 19 ~ 20 ° SR beating degree to meet the low-weight liquid filter paper Liquid absorption of 580 ~ 590g · m-2 and the thickness of 0.4mm requirements.
