viscositytemperaturepolyalphaolefinPAOmonoolefinmolecular structuredeterminationFor the liquid products of the oligomerisation of C3-C12 alphaolefins the values of poles of the Walther viscosity dependencies have been found to be a function of monomer size and oligomerisation initiation system. In this ...
1) viscosity-temperature relationship 粘温关系1. Factors affecting the viscosity-temperature relationship have been analysed,and the relavant predica- tion model has been regressed and related to the chemical structure of these viscosity index improvers. 选取3种常用的乙烯丙烯共聚物型粘度指数改进剂,...
SWELLING CAPACITY OF STARCH AND ITS RELATIONSHIP TO SUSPENSION VISCOSITY-EFFECT OF COOKING TIME, TEMPERATURE AND CONCENTRATION A range of concentrations (c) of wheat starch granules dispersed in water were heated at 60, 65, 70 and 75°C for 15, 30, 45, 60 and 75 min. Viscosity (η)......
Fitting expression of relationship gas viscosity, and temperature and/or pressure Gas viscosity is an important parameter for the performance of gas lubrication mechanism such as dry gas seal.The gas viscosity is related to temperature a...
The relationship between dynamic and kinematic viscosity is ν=μρm2s−1=kgm s−1kgm−3 For fluids, the density, ρ, is almost pressure independent. The same applies to ν. On the contrary, as ρ will vary only slightly with increasing temperature, while μ will decrease strongly, ...
The oils are 400 and 100 °°C C viscosity a large decline, viscosity index also dropped to 62, indicating that the oil is the base oil viscosity temperature performance additives, or viscosity index of the anti-shear performance is very poor. In particular, the sharp drop in temperature vis...

Viscosity – temperature stability refers to the difference between the zero- and infinite-temperature viscosities, rather than the activation energy. 展开 关键词: viscosity Arrhenius-type relationship temperature rheology 被引量: 70 年份: 2010
1) dynamic viscosity-temperature relationship 动态粘温关系 1. The concept ofdynamic viscosity-temperature relationshipof polymer melt was firstly proposed. 首次明确提出聚合物熔体的动态粘温关系概念。 2) viscosity-temperature relationship 粘温关系
Viscosity and electrical conductivity are two important physical properties for aluminosilicate melts, but their composition and temperature dependences are very complex because of the amphoteric behaviour of Al2O3. In general, these two properties in literatures are given separately. In the present ...
