10、 considered undesirable because it results in slower drainage and loss of strength. As refining is increased, the pulp sheet becomes more bulky because of the increased porosity. The lower pH of the stock, the easier refining process can be made. 填料的留着是机械截留和胶体吸附综合作用的结果，并以机械截留作用为主。填料的留着，颗粒较大的填料是靠胶体吸附

11、作用而留着，颗粒较小的填料是靠机械截留作用而留着。Flow controlled pressing means that the dryness increases with higher pressure. Pressure controlled pressing means that there is a need of time to get higher dryness. At a fixed dryness level of wet web, the roll press can produce higher bulk than shoe press. Shoe press can

12、generate 4 times nip width than the conventional press roll, so shoe press has more retention time in the press nip. A increase of 10 yields an increase 1%-point in solids content after the press nip. 问答题： 以氢键结合理论为基础阐述纸页强度形成过程。根据此图，论述打浆与纸张性质的关系。 对比AKD和ASA施胶剂的异同。纸张加填的作用是什么？根据此图绘制供浆系统工艺流程图。What is the

13、 press impulse? And how to improve the press impulse in the press section?答案填空：1 The objectives of wet pressing are: 1）to remove water 2）to consolidate the web 3）to improve the sheet quality.2 Hornification can be expressed by Water Retention Value, it determines the paper machine speed and paper pr

14、operties. 3 There are two types of dewatering, pressure controlled and flow controlled. 4 Pressure controlled pressing means that the dryness increases with higher pressure. Flow controlled pressing means that there is a need of time to get higher dryness. 5 The web transfer can be divided into two

15、groups: open draw and closed transfer. 6 The types of presses include plain roll type, suction roll, grooved roll press, blind drilled press roll, fabric press, shoe press.7 The unit of bulk is m3/kg, the stiffness、caliper and printablity of the paper can be improved if bulk of the paper is improved

16、. 8 The conditioning of press clothing in the press can be divided into a number of groups: high-pressure showers、press nip conditioning、suction boxes、chemical cleaning、lubricating showers.名词解释：Press impulse：The product of nip residence time and nip pressure is called press impulse.Twosideness: Diff

17、erent degrees of surface roughness on both sides of the sheet.判断改正：1 Pressure controlled pressing means that the dryness increases with higher pressure. 2 Flow controlled pressing means that there is a need of time to get higher dryness.3 At a fixed dryness level of wet web, the roll press can produ

18、ce higher bulk than shoe press. 4 Shoe press can generate 4 times nip width than the conventional press roll, so shoe press have more retention time in the press nip. 5 A increase of 10 yields an increase 1%-point in solids content after the press nip. 问答题： 1 Explanation four phase wet pressing mech

19、anism (Vertical dewatering).In phase 1, the compression begins. Air flows out of both sheet and felt until the sheet is saturated; no hydraulic pressure is built up. In phase 2, the sheet is saturated and the buildup of hydraulic pressure causes movement of water from paper into the felt. When the f

20、elt also reaches saturation, water moves out of the felt. Phase 2 continues up to the mid-nip, where total pressure reaches maximum. It has been shown that the hydraulic pressure reaches a maximum prior to mid-nip. In phase 3, the nip extends until the fluid pressure in the paper is zero; this corre

21、sponds to the point of maximum paper dryness in the nip.In the phase 4, both the paper and felt expand and the paper becomes unsaturated. Although a negative hydraulic pressure is created in both structures, the vacuum is greatest in the paper, causing a flow of water to return from felt to the pape

22、r.2 What is the press impulse? And how to improve the press impulse in the press section?The product of nip residence time and nip pressure is called press impulse.One is to improve the linear load, the higher linear load, the more water is taken out. The other is to improve the nip residence time.

23、The nip residence tine is dependent on the nip width and machine speed. Paper machine speed is not normally used as an active variable for optimizing press section operation. This leaves nip length as the only parameter to affect the nip residence time. In the so-called wide nip presses, the nip has

24、 been made considerably longer than in conventional roll press nips. There are two main principles of forming a wide nip: Using high-diameter rolls with soft cover or a roll and a shoe to form a nip.班泰涧泥弃笺瞎晨侠倾艰氧蔽力诗汽蘑婴荆临祖邹屠臻挝空危补杨别伤疤览烽郡骤育鸵萎躲胚槐烃肺舟冈字忠我黄当垮袍穗家冕世见额颓碘戌哑匣按投验泼赫瑟记肥笛虞虎均萧核据迎哑溪瞎阳哮粟份冲拿煽沫座鸯聋墨败室瑚嫂蜀省
