生产全木浆印刷书写纸张时,在高速造纸机压榨部的靴型压榨装置压区里为了提高对湿纸幅进行水分脱除作业的效率有必要装设一种将压缩毯与沟纹压榨(垫)组合成新系统。该文论述该组合系统在其运行过程里对靴型压榨装置的影响,如设计沟纹压榨(垫)带带体结构形式,使之能与压榨毯匹配。在文中还论述了该组合系统的毯体/带体的空隙容积当它在压区里时与其中水分流动之间的关系。使用了该系统后还出现了新的要求和新的参数。以及诸如对脱除水分的流量和水分脱除的速率的测定,使成纸纸幅表面的两面性平滑度和松厚度有较大的提高。
In order to increase the efficiency of moisture removal of the wet web in the nip of the shoe press in the press section of a high speed paper machine during the production of all wood pulp printed writing papers it is necessary to provide a system for compressing the blanket and groove Pad) into a new system. This article discusses the impact of the combined system on the shoe press during its operation, such as designing the form of the grooved belt (mat) belt to match the press mat. The relationship between the void volume of the blanket / belt body of the combined system and the flow of moisture therein when it is in the nip is also discussed. After the system was used, new requirements and new parameters appeared. As well as the determination of the rate of removal of moisture and the rate of moisture removal, provides a greater increase in smoothness and bulk on both sides of the finished paper web.
