摘要
The mechanical properties of the glue have great effects on the forward roll coating,which are analyzed here. The analysis shows that liquid viscosity,up and down rollers' speeds,diameters and the size of their gap have major impacts on coating property.The pressure and the shear force increase with the increases of the roll rotation speed,the radii and the viscosity of the glue,while decrease with the increase of the size of the roller gap. At a position of about 0. 8 mm from the nip symmetry axis by removing dimensionality,the pressure produces a maximum or minimum value,and the direction of the shear force changes.
