摘要： 通过观察在热油面上泡沫状态和油品温度的变化，研究了泡沫热态稳定性及泡沫性能对油温的影响因素。试验证明，油品温度决定泡沫的热态稳定性，泡沫在油面上稳定停留的临界油温为125 ℃；当油温＞135 ℃时，随着油温增加，泡沫消失速度越来越快。油温降速与油品温度、泡沫析液速度、油品黏度有关，而与发泡倍数无关。油温越高、泡沫析液速度越快、油品黏度越低，油品降温速度越快。

Abstract:

By observing the change of foam state and oil temperature on hot oil surface, the influence factors of foam thermal stability and foam performance on oil temperature were studied. The test proves that the temperature of the oil determines the thermal stability of the foam. The critical oil temperature at which the foam stays on the oil is 125 ℃; when the oil temperature is higher than 125 ℃, as the oil temperature increases, the foam disappears faster and faster. The decrease rate of oil temperature is related to the temperature of oil, the foam drainage rate, and the viscosity of oil, but has nothing to do with the foam expansion ratio. The higher the oil temperature, the faster the foam drainage rate and the lower the viscosity of the oil, the faster the decrease rate of the oil temperature
