Influence of Inertia on Liquid Absorption into Paper Coating Structures
نویسندگان
چکیده
We elucidate in this paper the influence of inertia of the imbibing liquid with special attention to the printing of paper. This is used to explain the observed differences between the absorption properties of fluids into large and small pores in paper coating structures. Without invoking arbitrary changes of the assumed constants in Lucas-Washburn (Washburn 1921) it has been hitherto impossible to describe the retarded imbibition seen when absorbing into highly porous structures containing large pores, for example in matt papers or coatings derived from very steep particle size distribution pigments.

Short Time Spreading of Offset Printing Liquids
Liquid–solid interactions are important for numerous natural and industrial processes in agriculture, coating, filtration, painting and printing. Understanding the effects of sequential absorption of oil components and water, in various arrangements, on porous coatings during the very short time it takes for a paper to pass through a printing machine is a prerequisite for a successful printing ...
متن کاملSensitivity Analysis of Frequency Response of Atomic Force Microscopy in Liquid Environment on Cantilever's Geometrical Parameters
In this paper, the non-linear dynamic response of rectangular atomic force microscopy in tapping mode is considered. The effect of cantilever’s geometrical parameters (e.g., cantilever length, width, thickness, tip length and the angle between the cantilever and the sample's surface in liquid environment has been studied by taking into account the interaction forces. Results indicate that the r...
متن کاملAn Experimental Investigation of Reactive Absorption of Carbon Dioxide into an Aqueous NH3/H2O/NaOH Solution
In this research, the reactive absorption of carbon dioxide in an aqueous solution of NH3, H2O, and NaOH has experimentally been investigated. The experiments were carried out in an absorption pilot plant in different operational conditions. The composition and temperature of both gas and liquid phases were obtained during the column height. The concentration of molecular ...
متن کاملTime-Dependent Structural Behavior of Repaired Corroded RC Columns Located in a Marine Site
The chloride corrosion of reinforcing steel in reinforced concrete (RC) structures is a significant reason for premature deterioration and failure of RC structures in aggressive environments such as Persian Gulf region. This is one of the most important sources of engineering and economic problems in developed countries. So, the repair and maintenance of RC structures exposed to corrosive envir...
متن کاملShort timescale inkjet ink component diffusion: an active part of the absorption mechanism into inkjet coatings.
The structures of inkjet coatings commonly contain a high concentration of fine diameter pores together with a large pore volume capacity. To clarify the interactive role of the porous structure and the coincidentally occurring swelling of binder during inkjet ink vehicle imbibition, coating structures were studied in respect to their absorption behaviour for polar and non-polar liquid. The abs...
