在常温下基质的粘度在450Pa.s，与管壁接触时会产生较强的粘附作用。当金属表面粗糙时，在其表面就会粘附一层基质，管壁表面越粗糙，粘附层越厚，这时这层粘附物不断受到冷却，粘附作用也越强，导热阻是这层粘附物与金属管壁的导热阻之和，导致传热系数入下降;
因素四、传热面积S
由热传导公式可知，基质与金属管壁接触的面积S越大，则冷却效果越好;
因素五、冷却水温
由热传导公式可知，当△T大时，则热交换的Q值大。经试验，当冷却水温在40度以下时，随着冷却水温度的下降，基质的温度与冷却水温之差越大，即温度变化越大，粘附在金属管壁的基质就越厚，如推动基质的压力过低，管壁上的基质不运动，致使导热阻增加。只有水温在40度以上时，温度变化越大，冷却笑过才会越好;
因素六、冷却水列管间距
