SU168178A1 - CEMENT DUST FOR INTRODUCTION TO CERAMIC MASS - Google Patents

Description

It is known the introduction of cement dust into the ceramic mass used in the manufacture of porcelain and fax products. But at the same time, due to the high content of soluble salts in the cement sore, coagulation of the slurries occurs.

A solution was proposed: to eliminate the coagulating properties of nonentar dust by transferring soluble salts into insoluble ones.

To do this, cement dust is sewn in certain proportions with alkaline-earth oxides and kaolin, after which the mixture is burned at 1100-1400 ° C; the resulting spec is granulated and ground.

Snack preparation can be carried out in various inappropriate settings. The temperature of the roasting depends on the composition, the cake, and may vary between 1100 and 1400 ° C.

The ratio of the components in the specimen is established in accordance with the variations in the chemical composition of the materials used

for the preparation of porcelain masses, as well as depending on the technical requirements for porcelain products of the same type.

According to the procedure, the composition of the mixture (in wt. O / o is as follows: cement dust 14-76; alkaline earth oxides 0.5-6; kaolin 18-80.

Subject invention

The method of preparing cement dust for introduction into the ceramic mass used for the manufacture, mainly of porcelain products, characterized in that, in order to eliminate the coagulating properties of cement

dust by transferring soluble forces into insoluble, cement dust is mixed with alkaline earth oxides and kaolinos, respectively, in an amount (by weight%): 14-76; 0.5-6; 18-80, after which the mixture is calcined at 1100-1400 ° C to obtain a cake, which is granulated and ground.
