Polyurethane Glue Ballast Adhesive For High-speed Railway
Polyurethane ballast adhesive is specially used for high-speed railway ballast bonding. It can effectively solidify the track bed, avoid the displacement of the gravel ballast, reduce rail wear and extend the service life of the railway, and can eliminate the noise generated by the train.
The glue is a two-component polyurethane adhesive, with good adhesion to ballast, high bonding strength, water and cold resistance, and curing at room temperature; the cured product is an insoluble and infusible rigid elastomer, which can withstand strong impact and not cause ballast The whole is broken; the glue layer does not affect the moisture permeability, which not only stabilizes the roadbed but also facilitates rainwater discharge.
