GB/T 22770-2008/ISO 12644.1996 Printing technology with falling rod viscometer Paste inks and material rheology1 ScopeThis standard specifies the paste ink was measured at room temperature conditions will not react determination of viscosity and yield value and binders. This standard applies to the apparent viscosity measured at 2Pa · s ~ 200Pa · s and paste inks viscosity and yield value of the binder.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Fluid friction occurs within the flow. Viscosity is generally defined as the ratio of shear stress (2.2) and a shear rate of (2.3), can be used Formula (1). η = (1) Where. --- viscosity [eta], in units of Pascal second (Pa · s); σ --- shear stress, the unit is Pa (Pa); [gamma] --- shear rate in second (s-1). 2.2 Acting on the unit area, and parallel to the plane of the role of force, unit. Pa. Note 1. The total weight is proportional to scram viscometer, the shear stress and the rod and the applied load, the available formula (2). σ = WA = (2) Where. σ --- shear stress, the unit is Pa (Pa); The total weight W --- rod and the loads in units of bovine (N); A --- apparent shear area, in square meters (m2); Note 2. Falling rod viscometer shear hole depth typically includes a tapered hole depth and hole depth. However, A is not an actual shear area, but the apparent shear area. 2.3 Laminar flow occurs when the fluid velocity gradient of each liquid layer, the unit s-1. Note. For rod drop viscometer, shear rate available formula (3).
