New Frost-Resistant Sand-Control Agent
Across China: Chinese researchers develop new frost-resistant sand-control agent LANZHOU -- A Chinese research team has developed a chemical sand-fixation material suitable for use in cold desert regions, which is expected to serve as a new tool for sand control and desertification prevention in such areas. The application of chemical materials to stabilize shifting sands is one of the primary methods of desertification control. This approach involves the use of adhesive chemical substances to bind loose sand particles together, thereby mitigating encroachment by wind-blown sand. However, conventional chemical sand-fixation materials have been mainly designed for hot and arid regions. In colder, high-altitude or high-latitude desert regions, such as the Qinghai-Xizang Plateau and the Mongolian Plateau, which are located in Northwest, Southwest and North China, cooler temperatures often render traditional methods of sand control ineffective. Researchers from the Northwest Institut...
