Materials used for the manufacture of slate:

Technical parameters of slate

  • Stamp concentrated load – at least 150 kgf (for 40/150 – any thickness. In other words, slate must withstand the weight of objects of 150 or 200 kg. You can walk quite freely on a slate roof during installation, at the stage of operation and possible subsequent repair. Large snow loads are also not terrible.
  • Density – an indicator at a level of at least 1.6 g / cm3 – for type 40/150; The higher the density, the higher the strength of the slate and its weight.
  • Bending strength – 16 MPa – for type 40/150;
  • Residual strength – noted at the level of 90%. This is the strength level of the damaged slate.
  • Water resistant – 24 hours.
  • Frost resistance – from 25 cycles These figures show the number of freeze and thaw cycles that do not lead to visible destruction of the slate.

Manufacturing technology of 8-wave slate

Amvrosievsky slate 8-wave is made using chrysolite-asbestos fibers with the addition of cement and water.
Pulp preparation and extraction. The process takes place in specialized mixers. In which the initial components of the raw material is mixed equally with water. Then the special With a tool, such an amount of material is extracted from the prepared mass as is necessary for the production of one sheet. The design features of the extractor allow water to run off. After removing excess liquid, the prepared mixture is transferred to another production site. It is possible to form the required profile using the shaper. Residual water is removed using a vacuum pump. After that, the billet formed and passed the initial drying is placed in the presser. Here the remaining water and the initial hardening of the material are completely removed. The removed moisture can be reused. After the final curing of the product, the sheets are cut to the desired size. Excess trimming can be reused. This is followed by quality control and packaging with shipment to the consumer.
