Abstract

L'invenzione copre procedimenti per la fabbricazione di pietre artificiali, le cui caratteristiche sono le seguenti:1. toni di colore di carattere elegante, toni di colore di dimensioni grandi e piccole di cristallizzazione del tono di colore, eccellente colore uguale o colore complementare di aspetto, resistenza all'usura, buona durezza e resistenza, migliore basso assorbimento rispetto alla pietra naturale, il vantaggio di risparmiare energia di sinterizzazione, ecc., mediante un notevole miglioramento di difetti irrisolti delle pietre artificiali prodotte mediante procedimenti tecnologici sinora utilizzati e così reggono il confronto con il granito naturale e provvedono un'efficace conservazione dell'energia.2. Parecchi procedimenti di fabbricazione dal procedimento 1 al procedimento 4:A. Procedimento 1: si mescolano e si agitano 100% di sabbia silicea, 70% di polvere di feldspato e 6% di polvere di pietra, con pigmenti inorganici per i toni colorati e una certa quantità di materiali fondenti. Quindi si aggiunge silicato di sodio alla miscela e nello stesso tempo si riscalda a 100-200°C insufflando aria calda nella macchina per 10-20 minuti. Quindi si essicca e si riveste la superficie delle particelle uniformemente con sabbia silicea.B. Procedimento 2: si aggiunge una quantità adatta di silicato di sodio al semi-prodotto ottenuto nel procedimento 1 a seconda della qualità e dei toni di colore, e dopo aver introdotto nello stampo, si comprime e si stampa in un prodotto.C. Procedimento 3: si essicca il prodotto stampato ottenuto nel procedimento 2 a 100-150°C mediante aria calda.D. Procedimento 4: si applica un aumento di temperatura graduale e lento al prodotto stampato ottenuto nel precedente procedimento dalla temperatura superiore allo zero a 750-850°C, mantenendo a tale temperatura per circa 30-60 minuti per rendere possibile ai materiali fondenti rivestiti del semi-prodotto di fondere, e si raffredda lentamente per 30 minuti sino a che la temperatura raggiunge 100°C.The invention covers procedures for the manufacture of artificial stones, the characteristics of which are as follows: 1. color tones of elegant character, color tones of large and small size of color tone crystallization, excellent equal color or complementary color of appearance, wear resistance, good hardness and strength, better low absorption than natural stone, the advantage of saving sintering energy, etc., through a considerable improvement of unsolved defects of the artificial stones produced by technological processes used so far and thus stand up to comparison with natural granite and provide effective conservation of energy. 2. Several manufacturing processes from process 1 to process 4: A. Procedure 1: 100% of silica sand, 70% of feldspar powder and 6% of stone powder are mixed and stirred, with inorganic pigments for the colored tones and a certain quantity of melting materials. Then sodium silicate is added to the mixture and at the same time heated to 100-200 ° C by blowing hot air into the machine for 10-20 minutes. Then the surface of the particles is dried and coated uniformly with silica sand. Method 2: a suitable quantity of sodium silicate is added to the semi-product obtained in method 1 according to the quality and color tones, and after having been introduced into the mold, it is compressed and printed in a product. Process 3: the molded product obtained in process 2 is dried at 100-150 ° C by hot air. Method 4: a gradual and slow temperature increase is applied to the molded product obtained in the previous process from a temperature above zero to 750-850 ° C, keeping at this temperature for about 30-60 minutes to make it possible for the semi-coated melting materials -product of melting, and it cools slowly for 30 minutes until the temperature reaches 100 ° C.
