Rock Mineral Wool — DEA Measurement

For the DEA measurement, A mineral wool infiltrated with the uncured resin was analyzed using the DEA 288.

Presented is the logarithm of the Ion ViscosityIon viscosity is the reciprocal value of the ion conductivity, which is calculated from the dielectric loss factor.ion viscosity and loss factor of the polyester resin on the wool versus temperature. During heating, the Ion ViscosityIon viscosity is the reciprocal value of the ion conductivity, which is calculated from the dielectric loss factor.ion viscosity decreases above approx. 70°C and the loss factor increases in the same temperature range. This is due to the softening of the dried resin. Above 153°C, the Ion ViscosityIon viscosity is the reciprocal value of the ion conductivity, which is calculated from the dielectric loss factor.ion viscosity increases up to approx. 237°C. This indicates a decrease in the ion mobility and therefore represents the Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing process of the resin. The Curing (Crosslinking Reactions)Literally translated, the term “crosslinking“ means “cross networking”. In the chemical context, it is used for reactions in which molecules are linked together by introducing covalent bonds and forming three-dimensional networks.curing process is finished at this temperature.
