Description

(54) CERAMIC MASS Mergelista flask is a natural material containing mainly quartz L 65%, and in the impurity complex there are capite and zeopite. When entering into the ceramic mass of the flask, instead of otstochitey such as quartz, chamotte, tiled or caplet battle, the mineralogical composition of the burned patch changed; Cristobadat was not detected, and the presence in the shard of mulpit, quartz and anorthite with the corresponding quality of the glass phase ensures the formation of a flow structure, which, in turn, ensures high performance properties of the products. The presence of impurity oxides in nepheline nienite, which are mineralizers of active calcium, formed during the decarbonation of calcite, and the ops creates the favorable conditions necessary for the formation of anorthite. The mixture is prepared as follows. Under laboratory conditions, the ground material is ground in a ball mill using a wet method to a residue on a sieve of 1OOOO resp. / Cm - 4%. The mill was loaded at a ratio of the smallest bodies of the material input equal to 2: 1: 1. Electrolytes are introduced together with water - liquid glass O 3, 3% (over 1% of dry material). Speaker dehydrate. From the press powder with a moisture content of 7.5%, tiles are formed at a specific pressure of 80 kg / cm. Samples are dried in a radiation dryer at a temperature of 270 ° C, fired in a tunnel kiln at temperatures 1. 63 1I DP pogguchenn optimapnoy charge prepare three mixtures, each of which contains, wt%: gpina kaopinite-hydrosypyudistuyu (p tykhatskuyu) 35-40, clay kaolinitovuyu (Nicholas) 22-35, flask marly (Mikhailovskaya) 152O, nephelineine (Mikhailovskoy) 152O, nephelineine (Mikhailovsky), 21-o, markelitan (Mikhailovskoy) clay, nepheline, Nikolayivskaya, 22-35; Syenite 1O-25. Example 1. In a laboratory mill load clay kaolin-hydromica (Ptykhatsky) in the amount of 35 wt.% From the weight of the whole mixture, clay kaolinite (Nikolaev) 35 wt.%, Topoka marly (Michael) 15 wt.%, Nepheline syenig 15 weight.%. The amount of BOftti is 50%, in which OC, 3% (in excess of 1OO%) of liquid glass is dissolved. The finished shyker has a moisture content of 50% and a residue on a sieve of 10OOO holes / cm -4.2%. A dry powder with a moisture content of 7.5% is prepared from the dried slip. Ceramic tiles are molded on the KRKP-125 press at a specific pressure of 8O kg / cm. The water absorption of the test specimens after calcination at 11OO C is 3.2%, and the frost resistance is more than 35 cycles. Example 2. The second composition of the charge is prepared similarly to the first, according to the technology of preparation and the composition of the main components. The mixture is characterized by the amount of kaolin-hydromica (clay) clay 4O wt.% And the amount of flask - 2 O wt.%. The water absorption index for this mass is 5.2%, the frost resistance is more than 35 cycles. The compositions of the proposed mass and properties of the samples are presented in the table.
