The Use of Peat Mineral Hydrophobizers as Anticlodding Agents for Powder Nitrile Butadiene Rubbers

摘要

Problems of clodding of loose materials and the main techniques to prevent it are considered. The main characteristics of nitrile butadiene rubber are briefly overviewed. The principle of the synthesis of hydrophobic modifying additives by thermochemical destruction of the organic substance of peat is described. A research method for an anticlodding agent based on peat mineral compositions is detailed. Comparative analysis of the efficiency of anticlodding agents based on kaolin and chalk is performed. It is established that the use of hydrophobically modified chalk decreases the clodding ability of nitrile butadiene rubber by 22.5 times under the long-term storage.
