COMPOSITE MATERIAL COMPOSITION FOR NEUTRALIZING ACID COMPOUNDS AND PIPE COMPRISING A SHEATH MADE FROM SAME
First Claim
1. A composite material composition for neutralizing at least one acid compound among carbon dioxide CO2 and hydrogen sulfide H2S, said composition comprising a mixture of a polymer material with a predetermined amount of chemically active products with said acid compound so as to irreversibly neutralize the corrosive effects of said acid compounds, characterized in that the mass fraction of said chemically active products ranges between 4 and 40% and said polymer material is selected from the vinylidene fluoride copolymers family, comprising at least one monomer selected from among the following monomers:
- hexafluoropropylene, perfluoro(methylvinyl)ether, perfluoro(ethylvinyl)ether, perfluoro(propylvinyl)ether, tetrafluoroethylene, perfluoro-butylethylene, fluoropropylene, chlorotrifluoroethylene, chlorodifluoroethylene, chloro-fluoroethylene, trifluoroethylene, and the monomer with the following formulation;
