标准摘要
[中文适用范围]: 本国际标准规定了一种加速方法,用于通过模拟印刷过程中的行为来确定涂层和未涂层纸和纸板的沾粘速度和抗沾粘性以及纸板上衬纸的抗分层性方面的表面强度。 过程。 由于测试区域有限和测试的一般特征,它通常不会检测局部缺陷,例如表面碎片。 该测试对于以平版胶印或凸版印刷的纸张和纸板尤其重要,因为这些技术中使用的油墨传统上具有高粘度和高粘性值。 由于现代柔性版油墨的粘性和粘度越来越高的趋势,该方法也可用于该领域。 在解释测试结果时,必须注意测试条件的差异、仪器的差异以及测试设备的校准状态的差异会严重影响结果。 这里确定的拾取速度等不应被解释为实际印刷机的运行速度。 注 1:虽然摆式 IGT 型测试仪不在本国际标准的范围内,但所描述的方法也可用于这些仪器。 由于速度剖面的差异,结果会略有不同。 注 2:本国际标准不包括 Westvaco 型设备的使用和粘性分级油墨的使用。 [外文原描述]: ISO 3783:2006 specifies an accelerated speed method for determining the surface strength in terms of the pick velocity and pick resistance of coated and uncoated paper and board, and in terms of the delamination resistance of the liner on paperboard, by simulating the behaviour in the printing process. Because of the limited area tested and the general character of the test, it will not usually detect local imperfections such as surface debris. This test is especially important for papers and boards which are to be printed in lithographic offset or letterpress, because the inks used in these techniques traditionally have a high viscosity and high tack values. Due to the increasing tendency for the tack and viscosity of modern flexographic inks to be high, this method is also useful in that field.
