Definitions

  • the perforated cement panels give an unsightly, very hard surface to the feet and spine, slippery after the rain.
  • the rebound of the ball is slow, a defect which is corrected by applying paint to the detriment of permeability.
  • the clay-sawdust slab lacks flexibility and yet it is ' . . brittle. Its fragility is due to the impossibility of obtaining a complete combustion of the clay-sawdust mixture and of controlling the formation of the porosity channels due to the inability to carry out the intimate clay-sawdust mixture and the completion of the combustion of these two elements.
  • porous concrete has a porosity which is not scientifically guaranteed by the well-known phenomenon of capillary tension, but by a fortuitous juxtaposition of gravel. Porous concrete has marked considerable progress in the construction of tennis courts when it comes to minimum maintenance and the possibility of playing outdoors all year round. Unfortunately, it has the following shortcomings that make the big
  • WIPO players refuse to use this surface: hardness at the ankles and spine, very slippery surface after rain, rapid wear of balls and shoes due to the very large roughness of the surface, irregular rebound of the ball due to roughness due to the very nature of porous concrete, change in the geometric profile of the balls resulting in modifications in their ballistics.
  • the present invention is an important step in the search for a material which makes it possible to obtain, if one speaks of the construction of tennis courts, terraces, sports fields, the following advantages:
  • the present invention has other important uses, in particular in the following fields: dialysis, buildings, roads, runways.
  • the present invention relates to a new material and its manufacturing process.
  • This new material with high otic and capillary bone permeability consists solely of mineral products. It has the property of absorbing and desorbing a large quantity of water or other liquids.
  • This material can have many applications in various chemical, medical, civil engineering, construction, road development, driveways, yards, terraces, sports fields, etc. industries.
  • this material can be in the form of insulating panels, slabs of different dimensions and different rates of otic bone permeability, etc.
  • semi-permeable membranes for dialysis and cationic and anionic membranes can be made.
  • the basic mineral product is alumina hydrosilicate called kaolinite which, in its pure state, is white. This product must be free of certain substances such as carbonate of lime, chalk, pyrite and rutile.
  • degreasing mineral substances which also have a high degree of wettability with water.
  • This degreaser is composed of several substances such as: quartz - mica - glass and silica.
  • this porosity it will be necessary to use a matrix made up of a combustible substance.
  • This matrix according to this process is made of carbon in the pulverized state. After a finely fined b ⁇ o age, this charcoal is selected according to the diameter of its grains, by several sieves. We can thus obtain grams of pulverized coal of a different particle size whose average grain diameter can range from 200 to 10 microns. This pulverized coal is then mixed with the colloidal material of clay or kaolin in the dry state, then with degreasing substances. After hydration of the well homogenized mixture, this dough is shaped, dried at 110 ° C and finally baked.
  • the oxygen necessary for this combustion will be supplied directly in the form of metal oxides or peroxides. These substances in powder form are mixed intimately with the grains of carbon before they are mixed with kaolin or clay. During cooking, the temperature of the oven will produce a cracking of the molecules of these oxides and the oxygen atoms thus released will be used for the combustion of coal. This internal combustion will produce combustion gases, in the form of onoxide or carbon dioxide. To obtain this chemical process, several reactions can be used, depending on the characteristics of the osmotic material to be obtained, either with a chemical potential or with an anionic potential.
  • the iron atoms being also released will remain in the osmotic matter and, therefore, give it an anionic potential .
  • the copper will give it a cationic potential.
  • each grain of carbon will produce a microcell in the material and in each of these cells the combustion gases will remain trapped. However, these gases being at high temperature, by their expansion, will produce a pressure on the walls of their cells and, by multiple capillary cracks, will escape. Thus, all these micro ⁇ cells will be united by a network of capillary cracks. The internal surface of these microcells as well as all this capillary network will be all the more important as the diameter of the grains will be smaller and their number more important.
  • the second process is the use of pulverized mineral coal, but which contains volatile matter in greater quantity, about 20 to 30%, such as houi l fatty or semi-fatty.
  • volatile matter in greater quantity, about 20 to 30%, such as houi l fatty or semi-fatty.
  • this volatile matter will be vaporized and, at its point of ignition, will burn with the grains of carbon using the oxygen supplied by the metal oxides.
  • the large amount of gas produced in this way will create a larger capillary network and therefore greater porosity throughout the mass of the material. This increase in porosity will decrease its coefficient of thermal conductivity and its density.
  • This insulating material thus obtained has the advantage of being mineral and therefore non-combustible. It can be used advantageously in the thermal insulation of buildings.
  • This substance is opaque to infrared radiation and will thus prevent heat loss by radiation.
  • the matrix will be made only with charcoal pulverized with great finesse, the diameter of the grains of which will be less than 20 microns.
  • the carbon will be mixed with the peroxides to provide it with the oxygen necessary for combustion.
  • This super-insulator may be used in certain advanced industries, particularly in the cryogenic field. It is also possible by this process to produce other osmotic materials by modifying the permeability such as semi-permeable membranes for dialysis as well as micron filters for the chemical industry and
  • f WIPO 7 also membranes for the purification of water by reverse osmosis. With membranes with cationic and anionic potential, we can even make electrical generators by RED (reverse-electro-dialysis). Another use is the development of roads and playgrounds where it is desirable to have a material which can quickly absorb rainwater and therefore an external surface which can dry quickly. In winter, this material can prevent the formation of ice. For roads, this material must also have the quality of being of great compressive strength, a high roughness on the surface on the rolling side so as to obtain the highest possible coefficient of adhesion. For the manufacture of this material, a fatty but infusible clay is used, above all containing no alkali and allowing it to be cooked at a higher temperature.
  • quartz and silica will be used, the dosage of which will be made so as to obtain greater hardness and a non-gelling product.
  • combustible matrix we will take semi fatty mineral coal, pulverized but of weak fineese. The diameter of the grains being thus larger, we will obtain slabs with a more grainy surface and a higher roughness. To also obtain good osmotic permeability, the carbon dosage will be determined accordingly.
  • the method of manufacturing slabs for equipping tennis courts ⁇ e will be as follows: Clay, pure, very fatty, is used, the particle size of which will be controlled by sieving.
  • a mixture of silica or quartz sprayed with fine granulometry and the dosage is done so as to obtain a hardness of the material of approximately 2 to 4 Kg / mm 2.
  • charcoal can be used, but preferably mineral charcoal, pulverized semi-fatty coal.
  • This coal will be dry mixed with Fe3 04 agn ⁇ t to supply the oxygen necessary for its combustion.
  • the presence of silica or quartz will increase the wetting angle and the use of small diameter carbon grains produce smaller microcells in the mass but in greater number for the same weight dosage.
  • the volatile matter of the carbon will produce a greater quantity of combustion gases, thus forming a larger capillary network. All of these factors will contribute to raising the permeability rate. in the mass of the material and to increase the speed of transport of the water through the material of the slabs.
  • a 38/24 / 4cm size slab manufactured using this method will contain 14.10 (1.4 billion) microcells with a diameter of 50 to 100 microns.
  • the internal surface of these microcells is approximately 85 m2; it is understood that this large surface makes it possible to obtain a very high permeability rate.
  • Figure 1 shows us a cross section of a slab and Figure 2 a view of its lower surface.
  • the upper surface l (fig. 1) is smooth, it is machined so as to be perfectly flat.
  • the lower surface is constituted by a double groove (x and y) in width and in length.
  • the groove in width is formed by a series of hollows 2 (fig. 1) and vertices 3 (fig 1).
  • the same form of grooves is also made along the length of the slab (z and).
  • This double crossed groove has the advantage, through their hollows, of producing drains in both directions, of channeling the water desorbed towards the discharge outside.
  • the tops of these double grooves have a dice-shaped geometry 4 (fig 2) on which the tiles are fixed to the ground.
  • This form of grooves therefore has a double advantage: to increase the outlet surface of the water relative to the upper inlet surface and to allow intercommunication between the drains so that the water flow can take place, even in partial obstruction of some drains.
  • the bituminous aggregate sole unlike concrete, is plastic to deformation as well as to compression. Therefore, it can follow any possible deformation of the soil without cracking.
  • the soleplate can be cast in one piece, without expansion joints which are often caused by water infiltration.
  • this sole by its plasticity is capable of absorbing all the instantaneous compression forces received by the feet of the player.
  • the elastic neoprene layer will largely absorb the contact force between the player 's feet and the tiles.
  • This sand-sole laminate support system of plastic aggregate plus elastic layer of neoprene produces a feeling of softness on the feet, like a grass field.
