T-700 TBM Tail Sealing Grease
Aiddem T-700 TBM Tail Sealing Grease enhances efficiency in shield tunneling with excellent water resistance and lubrication properties. It prevents mortar and groundwater infiltration and reduces friction between the segment and shield tail, with superior adhesion and no water leakage.
T-700 TBM Tail Sealing Grease provides sealing, waterproofing, and lubrication during the shield tunneling process, ensuring no water leakage and excellent adhesion. It is effective under a wide range of temperatures and conditions.
T-700 TBM Tail Sealing Grease
▋Description :
T-700 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 :
●Excellent water-resistant sealing properties;
●Excellent lubrication properties;
●Good pumpability over a wide temperature range;
●Good resistance to water impact;
●Excellent adhesion.
