With the continuous development of the coal industry, the depth and scale of coal resource mining are also increasing. In this process, a large amount of slime will be produced, which will cause serious pollution to the environment if it is not properly used and treated. As a new type of coal slime utilization, the role of waterless cannon mud has attracted more and more attention. Among them, the role of modified coal asphalt in waterless cannon mud has attracted much attention.
1. Introduction to modified coal asphalt.
Modified coal asphalt is a petroleum asphalt substitute prepared by the processing of coal tar fraction, which has the characteristics of good high temperature stability, low temperature flexibility, cohesiveness and anti-corrosion, and is widely used in construction, road, anti-corrosion and other fields. In waterless cannon mud, modified coal pitch plays a vital role in the performance of waterless cannon mud as the main binder and plasticizer.
Second, the role of modified coal asphalt in waterless cannon mud.
1.Increases the strength of waterless cannon mud.
Modified coal pitch acts as a binder in waterless cannon mud, able to bond a variety of different raw materials together, thereby increasing the strength of waterless cannon mud. Due to the high viscosity of the modified coal asphalt, it can fully infiltrate the surface of various raw materials and form a strong cohesion. At the same time, the modified coal asphalt is not easy to decompose at high temperatures, which ensures the stability of waterless cannon mud in high temperature environments.
2.Improves the flexibility of waterless cannon mud.
Modified coal pitch also has the effect of plasticizer, which can improve the flexibility of waterless cannon mud. By adding an appropriate amount of modified coal asphalt, the brittleness of waterless cannon mud can be reduced, so that it is not easy to crack in low temperature environment. This helps to improve the service life and safety of waterless cannon mud.
3.Enhance the anti-corrosion performance of waterless cannon mud.
The modified coal asphalt itself has certain anti-corrosion properties, and adding it to the waterless cannon mud can improve the anti-corrosion performance of the waterless cannon mud. This helps to extend the life of waterless cannon mud, reduce the frequency of repairs and replacements, and reduce production costs.
4.Optimize the production process of waterless cannon mud.
The use of modified coal pitch can also optimize the production process of waterless cannon mud. Due to the good fluidity of the modified coal asphalt, it can make various raw materials better mixed together, and the production efficiency is improved. At the same time, the addition of modified coal asphalt can also reduce energy and material consumption in the production process, which helps to achieve energy conservation and emission reduction.
3. Practical application of modified coal asphalt in waterless cannon mud.
In practical application, the role of modified coal asphalt in waterless cannon mud has been widely recognized. Through reasonable formula design and process control, the waterless cannon mud prepared by using modified coal asphalt has the advantages of excellent high temperature performance, low temperature performance and anti-corrosion performance. This makes the waterless cannon mud show good performance and stability in practical applications, and makes a positive contribution to the safe production and environmental protection of the coal industry.
IV. Conclusions. The role of modified coal pitch in waterless cannon mud has important practical significance and theoretical value. Through in-depth research and optimization of the application of modified coal asphalt in waterless cannon mud, it is expected to further improve the performance and service life of waterless cannon mud and provide more reliable technical support for the development of coal industry. At the same time, with the continuous improvement of environmental awareness and the increasing scarcity of resources, the wide application of modified coal asphalt as a renewable resource in the field of waterless cannon mud will also help promote the process of sustainable development and green manufacturing.
