| 摘 要： | 研究了不同螯合剂对脱墨浆过氧化氢漂白的稳定作用以及不同硅酸盐阻垢剂对硅酸盐垢的分散作用.复配出一种既可以稳定过氧化氢漂白又可以抑制硅酸盐结垢的双功能助剂（以质量分数计,DTPMPA 2.25%、DTPA 4.50%、EDTA 4.50%、硅酸盐阻垢剂A 15.00%,蒸馏水73.75%）.使用此助剂进行一段过氧化氢漂白,漂浆ISO白度可达到58%,比单独使用DTPMPA,ISO白度提高2.5%.

| Abstract: | The effect of different chelating agents on the stability of hydrogen peroxide bleaching of deinked pulp and chelating effect of different scale inhibitors on calcium in forming silicate scales were studied.A bifunctional agents which can not only stabilize the hydrogen peroxide but also inhibit scaling was obtained.It contains DTPMPA 2.25%,DTPA 4.50%,EDTA 4.50%,scale inhibitors A 15.00% and distilled water 73.75%.Using this bifuntional agents,the brightness of the bleached pulp by one stage peroxide bleaching could reach 58% ISO compared to the unbleached pulp,and the brightness could increase 2.5% ISO than that using DTPMPA only. |
