GLASS FIBER WITH IMPROVED BIOLOGICAL DEGRADABILITY |
摘要 |
The invention relates to a biodegradable glass fiber with sufficient solidity, resistance to humidity and good processing properties, which can be used damping and insulation purposes. Said glass fiber contains 58 to 60 % by weight SIO2; 15 to 20 % by weight Na2O; 0 to 3 % by weight K2O; 2 to 4.5 % by weight MgO; 5 to 9 % by weight CaO; 7 to 9 % by weight B2O3; 1.1 to 2.5 % by weight Al2O3; 0 to 0.5 % by weight SO4<2->and 0 to 1 % by weight of other components in relation to the mass of said fiber. |
