产品名称：德国PTI纸张吸水率测定仪

描述

For the determination of the water absorption of sized paper and board, including corrugated fibreboard, under standard conditions. It may not be suitable for paper of less than 50 g/m� or for porous papers such as newsprint or un-sized papers such as blotting paper or other papers having a relatively

的大小的纸和纸板吸水率的测定，包括瓦楞纸板，在标准条件下。它可能不适用于纸张小于50克/米�或纸张如新闻纸或联合国大小的纸等吸水纸或其他文件有一个相对

high water absorption. A test piece is weighed immediately before and immediately after exposure of one surface to the water for a specified time, followed by blotting. The result of the increase in mass is expressed in grams per square metre (g/m2). The standard model has a test area of 100 cm�. The model NV50 is delivered with 100, 50 and 10 cm� area.

高吸水性。试件称重之前和一个表面的一个特定的时间与水接触后立即，其次是印迹。在质量的增加，其结果是克每平方米表示（克/平方米）。标准模型有100厘米�试验区。该模型nv50交付100，50和10厘米�地区。

Test description

测试描述

100 ml � 5 ml of water, or proportionately less for a smaller test area, are poured into the cylinder, thus providing a head of 10 mm. The sample is placed on top and the lid closed. As the cylinder is turned over the timer starts automatically. The exposure time is selected according to the degree of water absorption of the paper and board. If, for example, a test time of 60 s has been selected, the cylinder is turned back after 50 s. The sample is quickly unclamped and placed (test face up) on a sheet of dry blotting paper on the couching table. 60 s after commencement of the test a second sheet of blotting paper is placed on top of the test piece and the excess water removed by pushing the couching table fully in under the couch roll and pulling it back again.

100毫升�5毫升的水，或相对少的一个较小的试验区，倒入缸，从而提供了一头10毫米。样品被放置在顶部和盖子关闭。当筒体翻转计时器自动启动。曝光时间是根据对纸和纸板吸水度选择。如果，例如，测试时间为60 s已被选定，气缸转身后50秒。样品快速松开并放置（测试面）上贴一张吸墨纸上干。60秒后，测试的二张吸墨纸开始被放置在顶部的试件和多余的水推拨表完全在伏辊和拉回来取下。
