Глазурь готов т следующим образом .The glaze is prepared as follows.
Компоненты шихты измельчают до прохождени через сито 64 о-гз/см и вар т при от одного до двух часов, затем фритту гранулируют в холодной воде. Полученную фритту после высушивани измельчают до прохождени через сито 10000 отв/см.глазурь нанос т на керамические издели методом окунани или пульверизации и отжигают в нейтральйо-окислительной среде в течение часа при 950-1050 с. Глазурь предназначена дл покрыти фасадных керамических плиток и обладает повышенной микротвердостью .The components of the mixture are crushed to pass through a sieve of 64 o-gz / cm and cook for one to two hours, then the frit is granulated in cold water. After drying, the obtained Frit is crushed before passing through a sieve of 10,000 holes / cm. The glaze is applied to the ceramic products by dipping or spraying and annealed in a neutral-oxidizing medium for one hour at 950-1050 s. The glaze is intended for coating facade tiles and has a high microhardness.
