| you are: Air izvest
At limestone roasting the carbonic gas making 44% from weight leaves, therefore komovaja negashennaja izvest it turns out in the form of the porous pieces actively co-operating with water. 123456
Clearing air to exhaust consists in hydration okisi calcium at water action on komovuju negashennuju izvest. Clearing is accompanied by a warming up of weight owing to allocation of a significant amount of heat - 950 kdzhkg. 123456 In the course of clearing pieces negashennoj to exhaust spontaneously dispergirujutsja, breaking up to thin particles in the size in some microns (is more thin, than at cement). Air izvest is unique knitting substance which turns in tonkodispersnoe a condition chemical dispergirovaniem. 123456 Enormous specific surface of particles causes the big water-retaining ability and plasticity of the limy test. After upholding the limy dough contains about 50% of firm particles and 50% of water. Each particle is surrounded by a thin layer of the adsorbed water playing a role of original hydrodynamic greasing. High plasticity of the limy test in a mix with sand is that property which so is appreciated at manufacturing of building solutions. 123456
Clearing komovoj to exhaust in the dough on specialised rastvornyh factories make in izvestegasilnyh cars. The mechanised clearing accelerates process, raises quality of the limy test. On small buildings komovuju izvest at first extinguish in tvorilah, and the limy dough through a grid merge in izves-tegasilnuju a hole in which clearing comes to the end.
