Ningxia mining water blocking materials

Polymer filling materials are used for filling, isolating air and sealing gas. After the two raw materials are mixed, they react quickly to form foam, which quickly expands to ~ times its original volume. After expansion, the foam will harden within a few minutes. The polymer filling material is rapidly foamed and molded, with a high foaming ratio. After curing, it has greater toughness, is not brittle or cracked, and has excellent sealing performance. It is filled and sealed when the requirements for mechanical strength are high. best choice. Scope of use
, permanent sealing within a certain pressure range
, rapid interception of harmful underground gases
, gas drainage tunnels, high-level drilling site filling and sealing
, sealing containment Rock cracks to prevent air seepage
, Construct airtight walls and firewalls within a certain range
, Hollow filling and roof filling of tunnels and working faces
, Back-wall filling of gob-side tunnel retaining supports and The small coal pillar cracks along the goaf tunnel are sealed.
Product Advantages
Rapid foaming, high foaming ratio, good flame retardant performance, good toughness and pressure deformation, able to adapt to the movement of rock formations, excellent sealing performance, simple and efficient construction.
