Product introduction

CLB F5/M is a new chemical product mainly used in the construction of EPB shield.

CLB F5 / M injects foam generated by expansion into the face to improve the soil in front:

■ Better control of earth pressure
■ Reduce torque and cutter head wear
■ Improve propulsion conditions
■ Improve propulsion conditions

Important characteristics

Foam is delicate and dry < br / > High strength of foam membrane wall < br / > High expansion capacity
Low usage
Biodegradable has no impact on the environment (*)

Product performance

CLB F5/M is mainly used for composite formation.

CLB F5/M mainly improves soil mass by adjusting concentration, expansion rate (FER) and injection rate (FIR).

The concentration of CLB F5/M mixed liquid can be selected according to geological conditions and earth pressure. The following effects can be achieved by using CLB F5/M:

■ Improve propulsion conditions
■ Improve screw press
■ Prevent mud cake, and the belt conveyor is easy to be unearthed
■ Compatible with most polymers
