| 摘要 |
The invention concerns a composite material composition capable of neutralising acid compounds and of being used in high temperature conditions, said composition being a mixture of a polymer material with a predefined quantity of reactive fillers, the mass fraction of the chemically active products is between 4 and 40 % and the polymer material is chosen from the family of vinylidene fluoride copolymers, comprising a vinylidene fluoride monomer, and at least one monomer being chosen from the following monomers: hexafluoropropylene, perfluoro (methylvinyl) ether, perfluoro (ethylvinyl) ether, perfluoro (propylvinyl) ether, tetrafluoroethylene, perfluorobutylethylene, fluoropropylene, chlorotrifluoroethylene, chlorodifluoroethylene, chlorofluoroethylene, trifluoroethylene, and the monomer of the following formula: CH2=CH-CF2-(CF2)4-CF3 and a pipe comprising at least one sheath produced with the composite material composition. |
