Zusammenfassung: | Method of reducing up to elimination of reducing core, i.e. inhomogeneity from the final product, to prolong the lifetime of the product, especially after the product was subjected to temperature changes. The method is performed in such a way, that at least one substance from the group comprising sodium silicate, sodium chloride, polyethylene glycol and finely crushed zeolites in amount 0.1 to 20 % by weight, calculated in regard to dry matter of addition, is added to ceramic dough before its drying.
Opisuje sa spôsob zníženia až odstránenia redukčného jadra, t. j. nehomogenít z finálneho produktu,čím sa predĺži životnosť výrobku, najmä pri jeho vystavení tepelným zmenám. Spôsob sa uskutočňuje tak, že sa ku keramickému cestu pred sušením pridáva aspoň jedna látka zo skupiny kremičitan sodný, chlorid sodný, polyetylénglykol a jemne drvené zeolity v množstve 0,1 až 20 % hmotn., počítané sa sušinu prídavku ku keramickému cestu. |
