The amount for use in foundry industry, moldable composition for the production of amounts for the foundry industry, process for the preparation of a moldable composition for the production of amounts for the foundry industry and use of rice husk ash
Summary "amount for use in foundry industry, moldable composition for the production of amounts for the foundry industry, process for the preparation of a moldable composition for the production of amounts for the foundry industry and use of rice husk ash "We describe amounts for use in foundry industry comprising (a) ash of rice husk containingBased on the total amount of the components detected in the ash of rice husk for the quantitative analysis of difratometria phase using X - rays (I) crystal modifications of silicon dioxide, (II) and (III) monoclinic feldspar amorphous silicon dioxide, a total content of at least 70% by weight,Preferably greater than 75% by weight of (I) crystal modifications of silicon dioxide and (II) the monoclinic feldspar and, based on the total weight of the composition moldable amount, the amount of ash of rice husk is in the range of 5 to 50% by weight, preferably of 5 The 25% by weight, (b) a cured binder, (c) optionally fibrous material.(d) optionally one or more additional loads, and (E) optionally an oxidizable metal and an oxidizing agent for the metal oxidizable. 1 / 1
