High Shear Capillary Viscosity of Coating Color on Paper and Paperboard 纸和纸板涂层颜色的高剪切毛细管粘度
该方法描述了使用带有毛细管结构的高剪切粘度计测量颜料涂层颜色的高剪切粘度的程序。在该方法中,在500000 s-1的剪切速率下,高剪切粘度被确定为mPa·s,简称毛细管粘度。该方法适用于各种涂层工艺中使用的水基颜料涂层颜色,如刀片、棒和薄膜转移涂层。通常,合适的颜料涂层颜色的固体含量在30%到80%之间,并且它们包含矿物颜料、合成和/或天然粘合剂和涂层添加剂。
This method describes a procedure for measuring high shear viscosity of pigment coating colors using a High-Shear Viscometer with a capillary configuration.In this method, high shear viscosity is determined as mPa·s at the shear rate of 500,000 s-1, and simply called Capillary Viscosity.The method is applicable for water-based pigment coating colors used in various coating processes such as in blade, rod, and film transfer coating. Typically, suitable pigment coating colors have a solids content between 30 % and 80 %, and they contain mineral pigments, synthetic and / or natural binders and coating additives.
