利用酶技术可以控制机械浆过氧化物漂白过程中产生的阴离子废物.Nalco’s公司生产的一种新产品将有助于改进供制造新闻纸和低定量涂布纸用的机械浆的质量,能够减少机械浆过氧化物漂白过程中产生的阴离子废物,这样可以更多地使用过氧化物漂白机械浆配抄纸张,提高纸机生产能力和减少工艺的变化。采用过氧化物漂白的机械浆在造纸过程中纸浆白度有下降趋势,由于在漂白过程中产生大量阴离子物料,它与纸机上阳离子添加剂相互作用.Nalco’s提供的新产品是利用果胶酶技术以降低机械浆过氧化物漂白过程中产生的阴离子量,酶的作用是通过解聚阴离子物料.新产品还包括无机凝聚剂,聚合物凝聚剂和复合凝聚剂.利用酶技术联合监测系统,可以稳定纸机操作、提高生产能力和最终产品质量.此外,新产品还可用于水处理系统,可明显降低化学药品消耗量和改进设备装置.
Using enzyme technology to control the generation of anionic wastes during the mechanical bleaching of peroxide blends, a new product from Nalco’s will help improve the quality of mechanical pulp for newsprint and low-weight coated paper, Anaerobic wastes produced during pulp peroxide bleaching make it possible to use more peroxide bleached mechanical pulp to dispense paper, improve paper machine productivity and reduce process variations. Pulp bleaching with peroxide blends tends to have a declining whiteness in the papermaking process, which interacts with the cationic additives on paper machines due to the large amount of anionic material that is produced during the bleaching process.Nalco’s offers new products using pectinase technology Reducing the amount of anions produced during the bleaching of the mechanical pulp peroxide, the enzyme acts by depolymerization of the anionic material.The new products also include inorganic flocculants, polymer flocculants and complex flocculants.Using enzyme technology combined with monitoring system, can stabilize Paper machine operation to improve productivity and end product quality In addition, the new product can also be used in water treatment systems that significantly reduce chemical consumption and improve plant equipment.
