Overview

Product overview

T-600 Shield Tail Sealant Grease is a uniform paste produced from fibers, thickeners, fillers, sealants and other materials through a specialized process. It is designed for shield tunneling applications where sealing, waterproofing and lubrication are required.

The product helps prevent mortar and groundwater outside the shield machine from seeping into the machine. When segments exit the shield tail, a layer of grease is applied on the outer side of the segment to reduce friction between the segment and the shield tail. The product is suitable for pump-fed shield tail sealing operations requiring stable pumpability and water impact resistance.

T-600盾尾密封油脂是由纤维、增稠剂、填料、密封剂等材料经特殊工艺制成的均匀膏状材料，适用于需要密封、防水和润滑的盾构施工场景。

该产品可防止盾构机外部砂浆和地下水渗入机内；当管片推出盾尾时，可在管片外侧形成油脂层，减少管片与盾尾之间的摩擦。该产品适用于需要稳定泵送性能和抗水冲击性能的盾尾密封作业。
