T-600 TBM Tail Sealing Grease
Aiddem T-600 TBM Tail Sealing Grease offers excellent sealing and lubrication during shield tunneling, with good water resistance and pumpability. It prevents groundwater and mortar from infiltrating into the shield machine while improving operational efficiency and surface protection.
T-600 TBM Tail Sealing Grease is a specialized paste used for sealing, waterproofing, and lubrication in the shield tunneling process. It prevents mortar and groundwater infiltration and reduces friction between the segment and shield tail.
T-600 TBM Tail Sealing Grease
▋Description :
T-600 TBM Tail Sealing Grease is a homogeneous paste made through a special process using fibers, thickeners, fillers, sealants, and other ingredients. Its main functions are to provide sealing, waterproofing, and lubrication during the shield tunneling process.
▋Application :
●Prevent the mortar outside the shield machine and groundwater from infiltrating into the shield machine;
●When the segment exits the shield tail, apply a layer of grease to the outside of the segment to reduce friction between the segment and the shield tail.
▋Features :
●Moderate water resistance and sealing performance;
●Excellent lubricating properties;
●Good pumpability over a wide temperature range;
●Strong resistance to water washout.
