摘要： There is provided a method of making white sack paper having a grammage of 50-140 g/m 2 and a Gurley porosity (ISO 5636/5) of 2-10 s, comprising the steps of:
a) providing bleached pulp, such as bleached sulphate pulp;
b) subjecting the pulp to high consistency (HC) refining and optionally low consistency (LC) refining to the extent that the sack paper obtains the Gurley porosity;
c) adding cationic polymer, such as cationic starch, to the pulp in an amount of 1.5-5.0 kg/ton paper; and
d) adding size to the pulp in an amount of 0.4-2.0 kg/ton paper; and
e) forming the sack paper from the pulp,
wherein less than 2 kg/ton paper of anionic starch is added to the pulp.
摘要翻译：提供了一种制备具有50-140g / m 2的克重和2-10秒的Gurley孔隙率（ISO 5636/5）的白袋纸的方法，包括以下步骤：a）提供漂白的纸浆，例如漂白硫酸盐纸浆; b）对纸浆进行高稠度（HC）精炼和任选的低稠度（LC）精炼，使得纸袋获得Gurley孔隙度; c）向纸浆中加入阳离子聚合物如阳离子淀粉，其量为1.5-5.0kg /吨纸; 和d）以0.4-2.0kg /吨纸张的量向纸浆中加入大小; 和e）从纸浆中形成袋纸，其中向纸浆中加入少于2kg /吨的阴离子淀粉纸。

摘要： There is provided a drop tester for a filled sack, comprising a substantially vertical linear drive unit having a sleigh movable in the direction of the extension of the linear drive unit, a platform for receiving the filled sack attached to the sleigh such that the platform may be moved in a substantially vertical direction, a fundament arranged under the platform such that the platform may be positioned on or just above the fundament, and a motor system connected to the sleigh, said motor system being capable of accelerating the platform above 1 g downwards. There is also provided method of drop-testing a filled sack, comprising the steps of: providing the sack on a platform in an upper position; accelerating the platform downwards above 1 g such that the sack is allowed to fall freely from the upper position; and stopping the platform in a lower position on or just above a fundament such that the falling sack hits the platform in the lower position and the impact of the hit is absorbed by the fundament.
摘要翻译：提供一种用于填充袋的跌落测试器，其包括基本上垂直的线性驱动单元，该线性驱动单元具有可在线性驱动单元的延伸方向上移动的滑块，用于接收附接到滑块的填充袋的平台，使得平台可以在基本上垂直的方向上移动，布置在平台下方的基础使得平台可以定位在基础上或正好在基础上方，以及连接到雪橇的马达系统，所述马达系统能够使平台加速超过1克向下。还提供了对装满的袋子进行跌落测试的方法，包括以下步骤：将袋子提供在处于上部位置的平台上; 将平台向下加速至1g以上，使得袋子可以从上部位置自由落下; 并将平台停止在基础上方或正好在基础上方的较低位置，使得落下的袋子在较低位置撞击平台并且击打的影响被基础吸收。
