Description
2 мин, затем загружают прокаленный пылевидный кварц 50-70% от расчетного количества , все перемешивают 8-10 мин. После этого ввод т подкисленную дисциллированную воду малыми порци ми. Температура суспензии не должна превышать 36-38°С, дл чего включают вод ное охлаждение стенок бака. Затем ввод т остальную часть эфироальдегидной фракции, глицерин, кислоту и пылевидный кварц до требуемой плотности. После этого всю суспензию перемешивают в течение 60 мин до получени однородной массы с температурой не выше 25°С. Приготовленна керамическа суспензи используетс дл нанесени первого сло керамики на модельные блоки. Дл нанесени второго и последуюш,их слоев керамики в состав ввод т дополнительно графит.2 minutes, then charged calcined powdered quartz is charged 50-70% of the calculated amount, everything is mixed for 8-10 minutes. Thereafter, the acidified, distilled water is introduced in small portions. The temperature of the suspension should not exceed 36-38 ° С, for which water cooling of the tank walls is included. Then the rest of the ether-aldehyde fraction, glycerin, acid and powdered quartz are introduced to the required density. After that, the entire suspension is stirred for 60 minutes until a homogeneous mass with a temperature not exceeding 25 ° C is obtained. The prepared ceramic slurry is used to apply the first ceramic layer to the model blocks. For the application of the second and subsequent layers of ceramics, additional graphite is added to the composition.
