The results showed that the shear viscosity of the polyacrylamide solution decreased with the increase of the temperature,furthermore the relation between ln η_a of polyacrylamide solution and 1/T consisted with the Arrhenius equation. 结果表明,随着温度升高,聚丙烯酰胺水溶液剪切粘度随之下降,剪切粘度...
The data from the corresponding load-displacement curves is converted into viscosity against shear rate adopting Stefans equation for flow between two parallel planes. The viscosity at processing conditions, i.e. at processing temperatures in the range of 1470 to 1480°C and zero to two minutes ...
1) relationship of lv and ling(law and codes) 律令关系 2) command relationship 命令关系 3) power law relation 幂律关系 1. Apower law relationwas found to be existed between viscosity coefficient n and shear rate r: and the exponent n was found to change gradually from O to—1/2 at ge...
This article proposes four relationships of dynamic viscosity – shear rate dependence for vegetable oils. The purpose of this study was to find a exponential dependence between temperature and dynamic viscosity of vegetable oil, using the equations. Equation constants A, B and C were determined by...
Relationship between rheological properties and structure of poly(vinyl chloride)The viscosity and extrudate swell as functions of shear rate and temperature as well as flow profiles and complex shear modulus were measured on the melt of three suspension poly(vinyl chlorides) of different molecular ...
starting and ending log10ηvalues, i.e., −2.93 and 12, respectively, in theTg-scaled inverse-temperature range between 0 and 1, corresponding toTg/T∞andTg/Tg, respectively. The distinct nature of the viscosity curves of different glasses can then be primarily described by the convex ...
55. Calf thymus DNA shows decreasing viscosity with shear rate and an increasing viscosity with temperature55. A recent study by Bravo-Anayaet al. has shown that the rheological behaviour is a result of interacting aggregates of the DNA molecules in flow54. The interaction between segments of ...
A power law relation was found to be existed between viscosity coefficient n and shear rate r: and the exponent n was found to change gradually from O to—1/2 at gel point during the development of gelation. 本文研究了明胶胶凝过程中的流变力学性质,发现粘滞系数η与切速 r 有幂律关系;在...
By identifying the dominating mechanisms that control the elastic and dissipative response, we can explain the rheology of these widely studied soft particle assemblies from the onset of elasticity deep into the overpacked regime. Interestingly, our results suggest that the friction between the ...
