The Features of Rheological and Tribological Behavior of High-Viscosity Polyolefine Compositions Depending on Their Content

Abstract

The influence of additive nature as well as its ratio on the rheological, tribological and technological properties of blends based on ultra-high molecular weight polyethylene has been determined. The energy costs impact in the polymer blends processing has been studied. It is shown that the rheological and tribological properties of the samples have a complicated dependence, which is determined by inhomogeneity of the system. The paper takes into consideration the influence of the friction coefficient of material and the viscosity of its melt on energy costs during processing by injection molding or extrusion

Adjusting the Performance Properties of Products Obtained by Injection Molding from Polyamide

“…Recent studies demonstrate the possibility of reducing energy costs by avoiding overloading the drive of injection units by optimizing process conditions. 15 Scientists are also focusing on improving the products obtained by this method. In particular, they show the methods of deformation optimization even at the initial stage by modeling and integrating an artificial neural network and using integrated automatic optimization tools.…”

Bio-Electrochemical Recovery of Copper from Dilute Acidic Solutions as a Function of External Resistance, Copper and Iron Concentrations

“…2 However, due to the multicomponent composition of the dispersed matrix, it is practically impossible to predict the functional effect of its components. 3 One of the key structure-forming components of colloidal dispersion systems is proteins of plant or animal origin. Each type of protein has different functional properties, such as solubility, structure formation, emulsification, gel and foam formation, viscosity increase, binding, and retention of water molecules.…”

“…Each type of protein has different functional properties, such as solubility, structure formation, emulsification, gel and foam formation, viscosity increase, binding, and retention of water molecules. 2,3 The use of nanomaterials is a promising area of innovative development of industrial technologies. The interaction of nanoparticles with biopolymers of dispersed systems (proteins, carbohydrates, lipoproteins) is a complex of complex chemical interactions, where the supramolecular organization of nanoparticles and the structure of the organic matrix play an essential role.…”

Simulation of Change in Density and Viscosity of Crude Oil When Mixing

“…6 Mathematical models, which describe the viscosity of oil mixtures, take into account the degree of dilution, the corresponding viscosity, and density of oil and diluents. 7 The formula for calculating the mixture viscosity was first proposed by Arrhenius 6 in 1887 and became the starting point for subsequent researchers. 8 The equation of exponent, 9 which is based on the values of molar fractions of the mixture components, is in close agreement with the experimental results.…”
