Definitions

  • the present invention relates to a novel type of mineral fibres.
  • Such known mineral fibres typically have the following composition:
  • the known mineral fibres are characterized by their high temperature resistance, but they are only slightly affected by salt solutions. Therefore they degrade very slowly when deposited at a tip or in other places in nature after use.
  • Mineral fibres of the above-mentioned composition can be produced from naturally occuring raw materials and other readily obtainable and inexpensive materials such as waste products from the production of mineral wool fibres and glass. Examples of such raw material compositions are listed in Table I. Tabl e I
  • Clay briquettes consisting of:
  • Clay briquettes consisting of:
  • Clay briquettes consisting of: 6 Clay 50 %
  • the solubility of the mineral fibres of the invention and known fibres has been examined by storing fibre samples weighing 830 mg in 250 ml of said Gamble's solution for 5 hours at a temperature which was increased from 37°C to 60 ⁇ C and by measuring the SiO ⁇ -concentration of the solution at the end of the test.
  • the mineral fibres according to the invention have a considerably higher solubility in the salt solution than the conventional known fibres.
  • a fibre sample according to NO patent application No. 874323 was subject to a similar examination.
  • the fibres had the following composition:
  • the tests were carried out with mineral fiber samples weighing from 0.5 to 1 g. These samples were placed on a refractory plate and then inserted into an oven which was preheated to a given temperature. After 30 minutes in the oven at this given temperature the fibre samples were removed from the oven and examined. If the dimensions, structures and elasticity of the fibres were unchanged this was taken as an indication of the fibres being resistant at the given temperature.
  • tests 3-6 listed in Table II showed that they were all resistant at a temperature higher than 750 ⁇ C which corresponds to the tem- perature resistance of the mineral fibre sample according to NO patent application No. 874323.
