Effect of light burned magnesium powder on the properties of liquid phase

Liquid phase quantity of a clinker

The clinker has too little liquid phase and is not easy to form grain. Too many easy to form compact bulk clinker. The amount of liquid phase is related to the content of Al2O3, Fe2O3, K2O, Na2O and MgO in the liquid phase. The coefficient of MgO is improved, indicating that MgO has a great effect on liquid phase and is close to the coefficient of Fe2O3. When the liquid phase amount is from 25% to 28%, it is the most favorable for the grain.

Surface tension of two liquid phase

The surface tension of liquid phase is an important property of liquid phase. It has a direct relationship with the nodal particles. The surface tension of the liquid phase increases easily, and the size of the clinker particles has a good linear relationship with the surface tension of the liquid phase.

The surface tension of the liquid phase is related to the electronegativity of the electrons in the outer layer. Some elements such as K, Cl and S have low surface tension values, which are not conducive to the granulation, but the surface tension of Mg and Al is higher, which is beneficial to the granulation.

Three liquid viscosity

The viscosity value of the liquid phase of different ingredients is different. Generally speaking, the viscosity of liquid phase decreases. It is beneficial to CaO and C2S to produce C3S in liquid phase, and also to grain. The viscosity of liquid phase is related to temperature, and decreases with the increase of temperature.

The liquid viscosity values of several elements coexisting are not the superposition of liquid viscosity values of single elements.
