研究了涂布纸的摩擦性能与纸在印刷过程中遇到的困难(如双面进纸)之间的关系。在高岭土与沉淀碳酸钙(PCC)的混合涂料中,PCC的比例大,会产生更大的静态和动态摩擦因数(COFs)。颜料的微观粗糙度如粒径的大小与摩擦因数有关,因为PCC粒子的形状会增大摩擦。在研磨碳酸钙(GCC)用量较高时压光会降低摩擦因数,但只用高岭土却不会改变摩擦因数。涂料中加入GCC会减少摩擦因数,动摩擦因数受GCC添加量的影响要比PCC的大,主要是由于GCC组分的特性,在表面会有选择性地被压平。将苯乙烯-丁二烯胶乳的加入量增加到14份,会降低摩擦因数,但是静摩擦因数在18份时达到最大。苯乙烯-丁二烯胶乳的防滑性质仅在静态下起作用。在润滑剂中,蜡在降低摩擦因数方面,对动摩擦因数的影响要比静摩擦因数的影响大得多。
The relationship between the frictional properties of coated paper and the difficulties encountered by the paper during printing, such as double-sided feeding, was investigated. In mixed coatings of kaolin and precipitated calcium carbonate (PCC), a large proportion of PCC results in greater static and dynamic frictional coefficients (COFs). The micro-roughness of a pigment, such as particle size, is related to the friction factor because the shape of the PCC particles increases the friction. Calendering reduces the coefficient of friction when GCC is used at higher levels but does not change the coefficient of friction with kaolin alone. The addition of GCC to the coating reduces the coefficient of friction and the kinetic friction factor is more affected by the amount of GCC than PCC, which is selectively flattened on the surface due to the nature of the GCC component. Increasing the amount of styrene-butadiene latex to 14 would reduce the friction factor, but the maximum static friction factor will be 18. The non-slip properties of styrene-butadiene latex work only in static state. In lubricants, waxes have a much greater effect on the kinetic friction factor than the static friction factor in reducing the friction factor.
