§1.引言

The removal of water in the forming section is often the rate-limiting

process during the manufacture of paper. In such cases, if a means can be found

to allow water to separate itself more quickly from the wet web of paper, then

the rate of production on the paper machine could be increased. Depending on the

details, there can be opportunities also to该技术可取代传统的电路蚀刻工艺 improve product quality. Vendors of

paper machine equipment provide a variety of devices, such as hydro foils,

vacuum boxes, vacuum couch rolls, and extended-nip wet-presses to encourage

quicker or greater release of water before the evaporative drying. This chapter

will focus on drainage-promoting chemical addi1方面要加强科普tives and the manner of their

implementation.

成型区的脱水常常是纸张生产时速度受到限制的环节。这种情况下,如果能找到一种方法加快湿纸页的脱水,那么纸机的生产速度就可以得到提高了,甚至纸张质量的提高也有了可能(跟具体情况有关)。纸所以1旦发现问题要及时处理;机设备供应商为此提供了多种装置,如脱水案板(hydrofoils)、真空箱、真空伏辊、宽区湿压榨(extended-nip

wet-presses)等,以在纸页被蒸发干燥前更快更多地获得脱水。本章将重点介绍促进滤水的化学助剂以及它们的应用方式。
