Temperature dependence of starch gel rheological properties

In this paper the mobility and factots affecting mobility of phenyl silicone rubber is studied. The results showed that the crystallinity of phenyl silicone rubber was declined because of the presence of phenyl and the higher the phenyl content, the lower the crystallinity when the phenyl content was low. The viscosity of the phenyl silicone rubber was rised as molar mass and phenyl content of the rubber was increased but the changes was not uniform. The viscosity of the phenyl silicone rubber was declined as temperature was increased and viscosity-temperature dependence of the high molar mass phenyl silicone rubber was larger. The influence of shearing on the viscosity and mobility of the phenyl silicone rubber were evident.

Physical Chemical

The temperature dependence of physical-chemical and biological properties of high-paraffin oil was studied in laboratory conditions. The experiments were carried out on the oil samples without agents and with addition of 800 g/t composition developed at the ratio of Difron-4201 + Difron-3705 = 1:1. The increase in the density for 3.8 %, in the ratio of surface tension for 16 %, in the ratio of kinematic and dynamic viscosity up to 88 %, as well as in the ratio of the thermal expansion for 50.11 % was observed in the samples without agents in the temperature rise to 50K. In the samples included in the composition, the surface tension, kinematic and dynamic viscosity sharply decresed in all temperature fields compared to the samples without agents, the density practically did not change, and the ratio of thermal expansion volume slightly differed in all temperature fields.
