KingSoil AC200 is a high performance synthetic polyelectrolyte dispersing agent in liquid form specially designed to prevent clay coalescence during drilling and shield tunneling.
Applications
For drilling and shield tunneling in presence of high content of fine particles and clay in order to prevent the aggregation between the mineral and shield
For Injection on the excavation front or in pressure chamber to avoid clay clogging and lumps formation
In case of drilling application, KingSoil AC200 is applied in the drilling field after being mixed with water, it is recommended to bring the solution in contact with the earth for 6 - 8 hours
In case of TBM application, KingSoil AC200 shall be added to the foaming solution line or to the water line
Advantages
Immediate dispersing effect
Assists in keeping the drilling tools clean by avoiding clay aggregation
