摘要： The invention discloses a method for selecting potential coating materials forhigh temperature applications. This method consists in measuring the zeta potentials of afouling substance and a coating or a potential surface. The figure shows the experimentaldevice used for the measurement of zeta potential. The pump (1) injects the electrolytein the loop (2). The heating strips (3) are wound around the tubing and are controlled bytemperature controllers (4). A YSZ electrode (5) and a reference electrode (6) on gaugeexternal control measure pH. The system pressure is measured by a pressure gauge (7)and held by a discharge valve (8). The solution is cooled with a cooling jacket (9). Thepulverulent substance (11) to be measured is packed into a rulon column (10) and heldby screens platinum and teflon filters (13). The electrode contacts are made via rulon endcaps (14). A differential pressure transducer (15) is provided.
