混凝土润管剂的研制和应用

Research and application of lubricant for concrete pumping pipe

预拌混凝土在开泵前必须对泵车和管道予以润湿和润滑。过去几十年来,全国各地预拌混凝土行业一直采用水和砂浆润管,其成本较高,而且浪费材料和车辆。通过研制的润管剂,降低成本,效果良好,节约用水、车辆和能源,有着良好的推广前景。

The ready-mixed concrete should be pumped before the pipe is processed with humidification and lubricant.Over the past few decades, the pipe was humidified and lubricated by mortar and water around all regions of China.The cost is high on the waste materials and vehicles.The studied and promoted lubricant for concrete pumping pipe features for lower cost, better effects, saving on water, vehicles and power.
