Abstract

Inventia se refera la un procedeu pentru taierea maselor ceramice, în dosebi a maselor ceramice cu oxizi nesinterizate. Cu ajutorul inventiei, se urmareste cresterea productivitatii la taierea unor astfel de mase prin realizarea unei mai bune calitari a taieturii, evitîndu-se impurificarea deseurilor de materiale. Sopul inventiei este atins, prin aceea ca, printr-o masa obtinuta prin extruderea, sînt ghidate unul sau mai multe jeturi de lichid cu o viteza de ejectie de cel putin o 100 m/s si cun diametru de 0,05 la 0,5 mm, viteza de înaintare a taierii fiind astfel aleasa, încît prin surplusul de lichid trimis în zona de taiere sa poata fi realizata o racire a masei. Ca lichid de taiere se foloseste o solutie apoasa de 0,5-4% a liantului masei ceramice cu oxizi.The invention relates to a process for cutting ceramic masses in the dosing of ceramic masses with non-sintered oxides. With the help of the invention, it is intended to increase the productivity at cutting such masses by achieving a better quality of the cut, avoiding the contamination of the material waste. The scope of the invention is achieved by the fact that, through a mass obtained by extrusion, one or more liquid jets with an ejection velocity of at least 100 m / s and a diameter of 0.05 to 0.5 mm, the cutting speed being selected so that by means of the surplus of liquid sent to the cutting area a cooling of the mass can be achieved. As a liquid, a 0.5-4% aqueous solution of the ceramic binder with oxides is used.
