It is understood that bromobutyl rubber is an irreplaceable raw material for the production of tubeless radial tire inner liners for vehicles. With the rapid development of China's tire industry, the consumption of bromobutyl rubber has exceeded that of ordinary butyl rubber. Currently, domestic demand all depends on imports, and the price is above 30,000 yuan/ton. Brominated butyl rubber is the trend of the future development of butyl rubber, and the prospects are very promising. For this reason, Yanshan Petrochemical's brominated butyl rubber technology development was included in the “Ten Long Tackling†project during Sinopec Group's “Eleventh Five-Year Plan†period. . It is expected that the device will be completed and put into operation by the end of 2008.
An excavator grading beam is a specialized attachment that can be fitted to an excavator. It is designed to help with grading, leveling, and excavating tasks. The grading beam is typically made of high-strength steel and is equipped with a series of teeth or blades that can be adjusted to different angles and depths.
The grading beam is attached to the excavator's arm, and the operator can use the machine's hydraulic controls to adjust the angle and depth of the teeth or blades. This allows the operator to precisely control the amount of material being excavated or leveled.
Excavator grading beams are commonly used in construction and landscaping projects, where they can be used to prepare building sites, level ground, and excavate trenches. They are also used in agricultural applications, such as land leveling and drainage work.
Overall, the excavator grading beam is a versatile and efficient tool that can help save time and effort on a range of excavation and grading tasks.
