本文研究了消失模涂料透气性随温度变化的规律 ,并从空气粘度、耐火骨料热膨胀和有机物热分解三个方面分析了温度对涂料透气性的影响
In this paper, the law of the air permeability of the lost foam coating with temperature is studied. The influence of temperature on the air permeability of the coating is analyzed from three aspects: the air viscosity, the thermal expansion of refractory aggregate and the thermal decomposition of organic matter
