为研究高速造纸用自支撑绑定成形网(self-supporting binding,SSB)结构对其耐磨性能的影响,分析不同参数(编织网纹、底面纬线直径、经纬纱线密度和插接方式等)下的 SSB成形网在 500、750、1 000、2 500 和 5 000 转的磨损试验条件下的质量损失率.结果表明:SSB成形网的磨损程度随摩擦转数增加而加重;编织网纹对SSB成形网耐磨性能的影响随经纬密度变化存在差异,经纬密较小时,底层采用 10 枚变则经面缎纹成形网时质量损失率最大,经纬密较大时,底层采用 10 枚变则经面缎纹成形网时质量损失率最小;其他参数相同条件下,SSB成形网耐磨性能与底纬直径、经纬密度呈正相关;SSB成形网主体结构耐磨性能优于插接工序形成的插接结构部分.
Structure and abrasion resistance properties of SSB forming fabric in high-speed paper manufacturing
To study the effect of the structure of self-supporting binding(SSB)forming fabrics for high-speed papermaking on their abrasion resistance,we analyzed the mass loss rate of SSB forming fabrics with different parameters(weave pattern,bottom weft diameter,warp and weft yarn density,and insertion method,etc.)under the abrasion test conditions of 500,750,1 000,2 500,and 5 000 cycles.The results show that the abrasion degree of SSB forming fabrics increases with the increase of friction cycles,and the influence of weaving pattern on the abrasion resistance of SSB forming fabrics varies with warp and weft densities.When the warp and weft densities are small,the mass loss rate is the highest with the bottom layer made of 10-variant warp satin pattern,whereas when the warp and weft densities are large,the mass loss rate is the lowest.Under the same conditions,the abrasion resistance of SSB forming fabrics is positively correlated with the bottom weft diameter and the warp and weft densities.The abrasion resistance of the main structure of SSB forming fabrics is better than that of the inserted structure formed by the inserting process.
