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.
A pipe lubricant for pumping concrete viscous materials. It is based on water-soluble silicone oil and adds sodium alginate, xanthan gum and other substances. It greatly improves the lubrication performance of pipeline lubricants. Compared with the traditional way of lubricating pipelines with cement mortar and pipeline lubricants formulated with cellulose ethers, alkali and inorganic salts and other substances, the lubrication of the inner wall is better and will not reduce The strength of concrete has no corrosive effect on steel bars. Because the aqueous solution of sodium alginate, xanthan gum, polyacrylamide and water-soluble silicone oil has a certain water-reducing and leveling effect on concrete, after the lubricant enters the concrete, it can be The concrete has better fluidity in the mold, vibrates more densely, and the surface of the concrete structural column is brighter.
This lubricant is insoluble in concrete and has good lubricity on the inner wall of pipes transporting concrete. It can be used to pump viscous objects such as concrete over long distances. Significantly reduces the friction between concrete and pipelines and pipeline resistance, extends the service life of pipelines and pumps, does not reduce the strength of concrete, is non-toxic, non-polluting, has good environmental performance, and has no corrosive effect on steel bars, making the concrete project more efficient. Quality is guaranteed.
This product is suitable for lubrication of on-site pump pipes for pumping concrete and various dry mortars. It has good adaptability to various grades of concrete and completely replaces the pump mortar of various pump pipes. At the same time, it can avoid the problem of pump clogging of concrete pumps and on-site sand pumps, reduce transportation vehicles, improve equipment utilization, and reduce the costs of enterprises using ready-mixed concrete and ready-mixed dry mortar.
Features: Reduce the process and shorten the operation time. It has the advantages of resistance to embroidery, fast, convenient, environmentally friendly, time-saving, labor-saving, and money-saving. It is a brand-new New technology for pumping construction.
For the past few decades, the ready-mixed concrete industry across the country has been using water and mortar to lubricate concrete pumps. The result is neither economical nor cost-effective. The concept of carbon environmental protection and energy saving and emission reduction. Concrete has attracted more and more attention and attention from the society. Every time concrete is made, pipe moistening is an essential process. Through the developed pipe moistening agent, the cost is reduced, the effect is good, water is saved, and there is a good prospect for promotion. The successful development and application of pump truck lubricant has made a positive contribution to the low-carbon, energy-saving and emission reduction of the concrete industry.
At present, lubricant has been successfully used and is a good substitute for mortar to lubricate pump tubes. Moreover, the investment and development cost is low. Taking small-scale investment as an example, it can be operated with a 100 square meter workshop and the equipment investment is less than 100,000. The profit margin is huge. Economic development has driven the development of the entire construction industry, and has also brought a broader market to our commercial concrete industry. In the future, the demand for pumped commercial concrete will also increase, which has good economic and social benefits.
This patent has been successfully applied and the technology is mature. We hope that people with a pattern, channel resources and vision can cooperate together. Contribute to environmental protection and save costs for corporate operations.
