PREPARATION OF BACTERIA BACILLUS AMYLOLIGUEFACIENS G TO IMPROVE THE TECHNOLOGICAL PROPERTIES OF CLAYS

Description of the project: the drug is used to improve the technological parameters of clays by their bacterial treatment. A change in certain parameters of clay (plasticity, sensitivity to drying) is due to the use of preparations of different compositions, depending on the initial properties of clay raw materials. 

Advantages: Production tests have shown that bacterial treatment can reduce the viscosity and thickening coefficient of the slip, significantly reduce the duration of the shard collection, and increase the mechanical strength of finished products. Air linear shrinkage of specimens after firing does not exceed 5%. An increase in the plastic properties of the pottery masses was noted.

The bacterial strain Bacillus amyloliguefaciens G is not pathogenic, toxic and toxigenic (Conclusion of the RUE “Institute of Experimental Veterinary Medicine named after S.N. Vyshelessky “No. 421-1-6 / 1409 of July 11, 2016).
