竹材化机浆实现工业化生产存在能耗高、漂白白度低、强度性能差的技术障碍。本论文研究表明,碱性过氧化氢预处理是一种较好的化学预处理方式。1.5%NaOH和2%H2O2用量的碱性H2O2预处理条件下,经10%H2O2漂白,可以获得26%ISO的白度增值,比碱性预处理和碱性亚钠预处理制得的化机浆白度增值高出4个白度单位;不同预处理方法浆料的强度性能存在较大差异,碱性过氧化氢预处理制得浆料的抗张指数较高,其抗张强度性能指标近20N.m/g,松厚度2.4cm3/g以上,初步达到纸板芯层浆的指标要求。
Bamboo industrial pulp machine to achieve the existence of high energy consumption, low bleaching whiteness, poor performance of the technical barriers. This paper shows that alkaline hydrogen peroxide pretreatment is a good way of chemical pretreatment. 1.5% NaOH and 2% H2O2 pretreatment conditions, the bleaching of 10% H2O2, you can get 26% ISO value of whiteness, alkaline pretreatment and alkaline than sodium pretreatment machine The whiteness of the pulp increased 4 whiteness units. The strength properties of the pulp with different pretreatment methods were quite different. The tensile index of the pulp prepared by alkaline hydrogen peroxide pretreatment was higher, and its tensile strength performance index Nearly 20N.m / g, bulk density of 2.4cm3 / g or more, initially reached the core of pulp pulp requirements.
