云点。云点也称浊点,馏分油在规定的条件下降温冷却,油品中所含的石蜡开始结晶而出现云雾状混浊时的温度称为云点。该温度与燃料的烃类组成及馏程范围有关,含直链烷烃愈多者云点愈高。值得注意的是,云点仅表现在测试瓶的 Cloud point. Cloud point cloud point, also known as the point, the cooling oil under the conditions of cooling, the oil contained in the paraffin began to crystallize cloud-like cloudy when the temperature is called cloud point. The temperature is related to the hydrocarbon composition and range of the fuel, and the higher the cloud point, the more straight-chain alkanes. It is noteworthy that the cloud point is only reflected in the test bottle
