POLYURETHANE IN INTIMATE CONTACT WITH FIBROUS MATERIAL

摘要

A sprayable polymeric material and a process for preparing the material whic h contains a fibrous material, dispersed throughout the polymeric material. A restriction free spray nozzle is provided for mixing and spraying the polymeric material having a fibrous material, the nozzle having a restrictio n free check valve. A reinforced structure, and a method of making the structu re are provided, the structure having layers of the polymeric material (both fi lm and foam) containing the fibrous material. The flexible liner is provided of a porous geotextile fabric and a polyurethane composition comprising the fibro us material sprayed over the geotextile fabric.
