Definitions

  • the present invention relates to a litter for elimination and prevention of snow and Eislätte.
  • Liquid crystals such as alcohols and glycols are described recently, but these can hardly compete with known Streusalzm ischungen due to the high evaporation losses. In addition, such liquid mixtures are often easily inflammable.
  • the object of the present invention is to provide a litter for elimination or prevention of snow and Eislätte, on the one hand has an over the prior art improved environmental compatibility, on the other hand shows a good effect against snow and Eisglätte and finally can be produced with low costs.
  • the dew effect should last as long as possible.
  • the substrate should become as handy as possible by using the litter.
  • the object is achieved by a litter to prevent ice and Schneeglätte that contains an ammonium salt on the phosphoric acid.
  • the litter according to the invention has an excellent effect in terms of the removal of ice and Schneeglätte. If an ice layer is sprinkled, the ice layer thaws very quickly and no new layer of ice is formed over a longer period of time. In contrast to known road salt, this effect occurs even at least -20 °.
  • the litter according to the invention also leads to a substrate made of asphalt, for example a road surface, becoming very grippy, as a result of which the braking angle of motor vehicles is reduced.
  • diamonium hydro gen phosphate (NhU) 2 HPO 4 ) is used. This is approved as a fertilizer and thus much more environmentally friendly than known grit salt.
  • the litter may also be produced by a mixture of an ammonium salt of phosphate acid and common salt.
  • a 1: 1 mixture of diam monium hydrogen phosphate and common salt has almost the same effects as pure litter from di di ammonium hydrogen phosphate. This has the advantage that on the one hand cost savings are possible, on the other hand, environmental pollution can be reduced by half. Even with this mixture, the effect is retained much longer than with a litter that consists only of common salt.
  • a further improvement according to the invention can be achieved if the ammonium salt of the phosphate acid calcium chloride is added.
  • Calcium chloride reacts with a strong exothermic heat development when in contact with water.
  • littering with calcium chloride is noticeably warmer on contact with condensation water, which further improves the dewing effect.
  • This effect is also obtained when a litter mixture of diamonium hydrogen phosphate, common salt (eg sodium chloride) and calcium chloride is chosen.
  • diamonium hydrogen phosphate, common salt eg sodium chloride
  • common salt eg sodium chloride
  • it makes sense to mix fumed silica.
  • 1% pyrogenic silica is suitable. This is hydrophobic and largely prevents the negative effect of clumping.
  • a scattering agent may have the following compositions:
  • a) pure ammonium salt of phosphoric acid e.g., diammonium hydrogen phosphate
  • ammonium salt of phosphoric acid and common salt eg sodium chloride
  • the proportion of common salt may be up to 70% by volume, preferably 50% by volume, or c) dispersant according to a) or b) with an addition of up to 30% by volume Calcium chloride, preferably 10% by volume, or d) Dispersant according to a) to c), with in addition up to 10% by volume of fumed silica (1%).
