Use of reinforcement glass wire composition comprising e.g. silicon dioxide, zirconium dioxide and sodium oxide to improve the resistance of plastics contacted with corrosive substances (particularly acids or bases)

摘要

Use of reinforcement glass wire composition (I) comprising silicon dioxide, zirconium dioxide, sodium oxide, alkaline earth metal oxides, manganese oxide and zinc oxide, aluminum trioxide, boron trioxide, ferrous oxide, calcium fluoride, titanium dioxide, potassium oxide and/or lithium oxide to improve the resistance of plastics contacted with corrosive substances (particularly basic and acidic). Use of reinforcement glass wire composition (I), comprising silicon dioxide (SiO2) (62-75), zirconium di oxide (ZrO2) (7-11), sodium oxide (Na2O) (13-23), alkaline earth metal oxides, manganese oxide (MnO) and zinc oxide (ZnO) (1-10), aluminum tri oxide (Al2O3) (0-4), boron tri oxide (B2O3) (0-6), ferrous oxide (Fe2O3) (0-5), calcium fluoride (CaF2) (0-2), titanium di oxide (TiO2) (0-4), potassium oxide (K2O) and/or lithium oxide (Li2O) (less than 0.1%) to improve the resistance of plastics brought into contact with corrosive substances (particularly basic and acidic). An independent claim is also included for a composite formed by (I).
