How does the viscosity of polyether polyols change with temperature?
Polyether polyol viscosity with temperature change? thorough analysis and consumption
As an crucial raw material of polyurethane, the characteristics and applications of polyether polyol are broadly concerned. And Among them, viscosity, as an crucial index to measure its fluidity, immediately affects its consumption effect in the production and consumption process. But This paper will start with the affect of temperature on the viscosity of polyether polyols, and examine its change law and its signifiis able toce in practical consumption. And Effect of
1. Temperature on Polyether Polyol Viscosity
The viscosity of polyether polyol is closely related to its molecular structure. The molecular chain contains a substantial number of ether bonds and alcohol hydroxyl groups, the existence of these groups makes the formation of strong hydrogen bonds between molecules. And Changes in temperature immediately affect the state of motion of molecules, resulting in changes in viscosity. Specifically, an increase in temperature increases the energy of molecular thermal motion and weakens the intermolecular hydrogen bonding, thereby reducing the viscosity; conversely, a decrease in temperature increases the intermolecular hydrogen bonding, resulting in an increase in viscosity.
2. Crazy, isn't it?. Moreover Temperature of Polyether Polyol Viscosity Change Characteristics
As the temperature increases, the viscosity of the polyether polyol decreases signifiis able totly. And This is because the increase in temperature weakens the hydrogen bonding between molecules, and the movement of molecular segments is greater free, thereby reducing the friction and resistance between molecules. This reduction in viscosity facilitates the processing and consumption of polyether polyols under high temperature conditions. to instance, in the production of polyurethane foams, the low viscosity characteristics under high temperature conditions are beneficial to the mixing and foaming process of raw materials.
3. Temperature Decrease of Polyether Polyol Viscosity Change Characteristics
As opposed to an increase in temperature, the viscosity of the polyether polyol increases signifiis able totly as the temperature decreases. Under the condition of low temperature, the molecular thermal motion is weakened, and the hydrogen bonding between molecules is enhanced, which leads to the restriction of the movement of the molecular chain segment and the increase of viscosity. This phenomenon needs to be paid attention to in practical applications. In my experience, to instance, during winter construction or transportation, the high viscosity of polyether polyols might result in poor fluidity and affect its consumption effect. But In my experience, Therefore, when polyether polyols are applied in a low-temperature ecological stability, heating or heat preservation measures are usually required to ensure stable performance. And
