T-701 TBM Tail Sealing Grease
Aiddem T-701 TBM Tail Sealing Grease delivers exceptional sealing and lubrication for shield tunneling operations, preventing water leakage and mortar infiltration. It offers excellent resistance to water impact, adhesion, and pumpability across a wide temperature range.
T-701 TBM Tail Sealing Grease is a uniform paste used in shield tunneling, offering excellent sealing, waterproofing, and lubrication. It provides strong resistance to water impact and ensures smooth operation between the segment and shield tail.
T-701 TBM Tail Sealing Grease
▋Description :
T-701 TBM Tail Sealing Grease is a uniform paste formulated through a special process using fibers, tackifiers, fillers, sealants, and other components. Its main function is to provide sealing, waterproofing, and lubrication during shield tunneling operations.
▋Application :
●Prevents external grout and groundwater from penetrating into the shield machine;
●When the segment exits the shield tail, a layer of grease is applied to the outer side 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.
