Concrete is a commonly used building material. During on-site construction, it is mainly poured by pumping technology. Before pumping concrete, the pump truck and pipes must be moistened and lubricated to reduce the friction resistance of the pipes during concrete pumping and ensure smooth pumping. The traditional method of pump lubrication mainly uses pump lubrication mortar. In the past few decades, the ready-mixed concrete industry across the country has been using water and mortar to lubricate pipes. This requires concrete companies to invest a lot of manpower, material resources, and financial resources in production.
First, in terms of raw materials, when cement, river sand, and water resources for production are currently in short supply, still using these raw materials to produce mortar that only has the function of lubricating pumps will cause a lot of resources. Waste; second, in terms of dosage, generally at least 1 cubic meter of pump mortar is needed, while ground pumps with long pipelines require 2-3 cubic meters of pump mortar. The amount of mortar used over the years is huge; third, in terms of funds , the concrete industry has serious financing problems and long capital turnover time. However, raw materials need to be settled in cash. The long-term use of pump mortar in large quantities will increase the pressure on working capital for concrete production companies. In view of the shortcomings of traditional mortar, which include high cost, waste of materials, damage to vehicles, waste of equipment, and are neither economical nor energy-saving and environmentally friendly, the development of high-performance, economical concrete pumping agents is a good solution to improve concrete pumping capacity. .
The lubricant is made of a variety of polymer materials. It can be quickly dissolved by manual stirring for 3-5 minutes at room temperature and form a transparent and stable viscous liquid. The liquid after the lubricating agent is dissolved passes through the pipeline as a whole, and part of the lubricating pump solution adheres to the pipeline, thereby achieving the effect of lubricating the pump tube. Each pumping only requires 1-2 packages of lubricating pump, and each package weighs about 300 Gram, easy to carry, and the lubricating pump solution and concrete do not dissolve each other, so it will not affect the working performance and quality of the concrete. It is also very convenient to use. There is no need to add any other equipment or separate lubricating pump. The lubricating pump liquid is in The front end of concrete can also be carried out at the same time as concrete pumping, greatly reducing manpower and material expenditures.
