INTRODUCTION OF REINFORCE MATERIAL

Huierda reinforce material (organic/inorganic) is a highly reactive, two-component modified flame retardant polyurethane used for stabilisation of fractured strara of underground coal mines, water stopping and sealing air leakages. It is consists of two component A+B, mixed at a volumetric ratio of 1:1, applied by injection into the strata where its low viscosity gives it the ability to penetrate the smallest fissures. Thereafter it expands and sets to effecitively consolidate and seal the area. Huierda reinforce has great adhesive strength and super-strong mechanical properities which create an excellent bond with the strata. Its high flame retardancy are necessary to gurantee construction security.
