It is a problem that has troubled people for more than 100 years. Water not only has a negative effect on the lubrication of grease, but also damages machine parts. Research results in recent years have shown that Calcium Sulfonate lubrication can be used for water environment, so it is suitable for various industrial equipment and food processing equipment. (According to industry people, manufacturers should vigorously try to develop calcium sulfonate lubricating fat, because calcium sulfonate can also play an effective role in a water environment.)
Calcium sulfonate has superior waterproofing, and has become the fastest developed lubricant thick agent in recent years. As the number of calcium sulfonic acid lubricating fat continues to rise, more and more people have applied it to the equipment and food production equipment of steelmaking factory. (1) Utilization and advantages and disadvantages of anti -water lubrication According to the United States Lubrication Association, it is learned that the relevant data of the lubricating production survey report: In recent years, the global output of calcium sulfonate lubricating fat is steadily rising, from 6,500 tons in 2001 to 32,000 tons in 2015. Calcium sulfonic acid lubrication is now applied to a working environment of high temperature, humidity and high load, such as the mechanical equipment of mining, steelmaking plant, power plant, railway and paper mill, and electric valves, ship equipment, underwater equipment, underwater equipment , Food processing equipment and off -road equipment. Adding additives to calcium sulfonic acid lubrication can make the performance better. Although the main disadvantage of calcium sulfonate is the low temperature performance and weak pumping properties. However, these problems can be improved by using additives. Although different types of calcium sulfonate have different advantages and disadvantages, they all have high pouring points and excellent pole pressure resistance. (2) Anti -water anti -water resistance test In order to understand the working mechanism of calcium sulfonate lubricating fat when encountering water, industry people conducted a lubricating grease and water -resistant washing test (ISO 11009) and lubricating fat spraying test (ASTM D4049). The total alkali value of this kind of fat is 400, the quality loss after water was washed less than 2%, and the quality loss after injection was 15%. In addition, the standard of the "ASTM D8022) standard" ASTM D8022) standard shows that the working environment of the water does not affect the cone entering. Some steelmaking equipment requires less than 5%after washing the fat. At this time, some additives need to be added to improve water resistance.
