| titleOfInvention | Cracks and fissures in foundry sand molds |
| abstract | "ANTITRINCES AND FISSURES IN FOUNDRY SAND MOLDS". Patent for a reddish-beige powder in the average particle size of MESH 325, with a density of 3.2 g / cm ^ 3, composed of magnesium aluminum silicate, with small percentages of iron oxide, calcium oxides, oxides of sodium and potassium oxides which is added to the sand before the resin is placed in a proportion calculated by the reaction stoichiometry causing contact with the material to be melted to form a film and this reaction creates small spaces which causes the Sand having its thermal expansion does not exceed the volume of the mold not causing the cracks and cracks and these spaces makes the mold easy to break. |
