Pipe Lubricant for Pumping Concrete Goo

With the development of economic construction, more and more high-rise and super-high-rise buildings are built in the city. All ready-mixed concrete uses car pumps or concrete pumps and is connected to Long pipes carry concrete to construction sites. During the concrete transportation process, there is friction resistance between the concrete and the inner wall of the transportation pipeline. The existence of this friction resistance greatly slows down the speed of concrete transportation, often causing pump blockage accidents, increasing energy consumption, and increasing production costs.

In order to reduce the frictional resistance generated by concrete during pipeline transportation, the traditional method of lubricating pipelines is to use the cement mortar method, that is, pump the concrete before pumping Send some prepared cement mortar to lubricate the concrete delivery pump and pipes. Since most of the cement mortar used to lubricate the pipes is mixed with the subsequently transported concrete, this will cause the concrete grade to be lowered, and more seriously, it will cause construction quality accidents. , Therefore, the traditional method of lubricating pipes with cement mortar has serious construction quality hazards.

In recent years, a pipeline lubricant formulated from cellulose ethers, alkali and inorganic salts has appeared in the construction market to replace the lubricating pump. Cement mortar, although this substance can play a role in lubricating pipelines, the pipeline lubricant prepared with this type of substance has poor uniformity of solution during use, is prone to sedimentation and stratification, and cannot evenly wet the pipeline in long pipelines. The inner wall, therefore, does not do a good job of lubricating the pipe. Alkali and inorganic salts entering the concrete in large amounts locally will affect the strength of the concrete and corrode the steel bars in the concrete, causing quality hazards to construction projects.
