1. This technology belongs to the field of lubrication technology, specifically involving a pipe lubricant or pump lubricant for sky pumps and ground pumps and a preparation method thereof.
Background technology:
2. For traditional pump mortar, concrete companies need to invest manpower Material resources to produce. In the current shortage of cement and sand resources, it is actually a big waste to still use these raw materials to produce pump mortar. In addition, generally a pump lubrication requires at least 1 cubic meter of lubrication mortar. For ground pumps with long pipelines, sometimes 2 to 3 cubic meters of lubrication mortar are needed to lubricate the pump. These raw materials require cash settlement. , and it is also a very large expense for concrete production companies that require advanced financing for concrete products.
3. Pump truck lubricant is made of a variety of polymer materials. It is stirred mechanically or manually for 3 to It can be quickly dissolved within 5 minutes and form a transparent and stable viscous liquid. When the liquid after the pump lubricant is dissolved, the entire liquid passes through the pipeline, and part of the pump solution is lubricated. It adheres to the pipe to lubricate the pump pipe, and the pump solution and the concrete do not dissolve in each other, so it will not affect the various properties of the concrete. It is also very convenient to use. There is no need to add any other equipment or a separate lubricating pump. The lubricating pump fluid goes in front of the concrete and can be carried out at the same time as the concrete pumping, which greatly saves the expenditure of manpower and material resources.
4. Traditional pump mortar sometimes needs to be transported by a separate transport truck, and sometimes the pump mortar is placed in concrete mixing The upper part of the transport truck is loaded with concrete. This is not only a waste of vehicle use, but if the transport truck loaded with pump mortar and concrete at the same time cannot rotate during transportation, otherwise the concrete and mortar will be mixed together. If the road is long or the concrete workability is slightly poor, it will If the workability does not meet the requirements, it will be returned. In addition, the first truck of concrete after the pump cannot be rotated during the road, resulting in poor workability, and it is also easy to cause the pump to become blocked. Pump truck lubricant is very convenient to use, so many pump truck drivers always keep a few bags on their cars, so that they can quickly and easily achieve the purpose of lubricating the pump.
5. Since the strength level of pump mortar is different from that of concrete, it is generally mainly used for pump lubrication and has little other uses. Some construction units use pump mortar for Some places that do not require high strength, such as floors, construction site floors, etc. The cost of pumping mortar is a huge waste if it is paid by the concrete company or the construction unit. At the same time, pump mortar also brings some quality hazards. In the past, there have been serious quality accidents in some construction sites where pump mortar was used for structural parts, resulting in unqualified project acceptance and final demolition.
6. Comparison of pump lubricating performance. The pump lubricating effect of some better quality pump truck lubricating agents is better than that of pump lubricating mortar. The lubricating effect of mortar is better than that of pump lubricating agent. The mechanism is that the friction of the lubrication pump mortar is small. When passing through the pipeline, some cement slurry will adhere to the pipe wall. This cement slurry lubricates the concrete transported later. Based on this principle, the pump truck lubricant is It is composed of polymer materials. The film layer adhered to the pipe wall after wetting has a significantly better wetting ability than the pump mortar.
7. Chinese patent201210221778.6 A concrete pumping pipeline lubricant and a preparation method thereof are disclosed. The concrete pumping pipeline lubricant product prepared by this technical method has stable performance, low price, and low dosage. It has good water solubility and can significantly reduce the friction between the concrete/mortar and the pump pipe
wall. It has no adverse effects on the concrete/mortar and is environmentally friendly and pollution-free. This patent belongs to an aqueous pumping pipe lubricant. Compared with powdered pumping pipe lubricants, the price is too high and it is inconvenient to use. In addition, polyoxyethylene and acrylic polymers are dissolved in water in advance and may degrade and lose their lubrication function.
