Lubricant is a new material used to replace water and mortar to moisten the pump and pump pipes before pumping. For example, the lubricant produced by Beijing Green Concrete Technology Co., Ltd. is divided into ordinary type and high-efficiency lubricant specially designed for ground pumps. The special lubricating agent for floor pumps can be used for lubricating pipes up to a length of more than 200m. Each 500g can replace 1.5-2m³ of mortar and moisten the pipe for 100m. The product is white powder. At room temperature, the lubricating agent: water = 1:100-1:120. Stir mechanically or manually for 3-5 minutes to quickly dissolve and form In order to prevent moisture residue and allow the lubricating agent to fully lubricate the pipeline, place a sponge ball at the feed port before unloading the viscous solution into the pump bucket, start the pump to pump at low pressure and speed, and unload the lubricating agent when the lubricating agent is about to be pumped out. Pour in the concrete and use the concrete to push the lubricating agent along the pipe. The lubricating agent can form a 1-2mm lubricating layer in the pump pipe, which is beneficial to the passage of concrete. The very small amount of lubricating agent residue discharged from the front end of the pump pipe can be unloaded on the formwork. In addition, because the amount is very small and it is alkaline, it is harmless even if mixed into concrete. This product is a green and environmentally friendly product. After use, it can also improve the wear resistance of the pump pipe wall by 15%.
The use of lubricant can reduce the amount of lubricating mortar and eliminate the need for vehicles to transport water and mortar, thus reducing fuel consumption and environmental pollution. The cost of lubricating agent is low, about 1/8 of that of mortar of the same strength level. , is an energy-saving and consumption-reducing product worth promoting.
