Abstract
If it is possible to prepare a series of standard carriers which differ in tribo-electric property in a certain orderly manner, one can expect to determine tribo-electric coodinates (positions in tribo-electric series) of fine particles compared with such carriers by “blow-off” method.
Such a series of standard carriers have been obtained by coating natural sand with mixtures of tribo-electrically positive ethyl cellulose and negative nitro cellulose in varying mixing ratios.
Several inorganic and organic compounds were subjected to TEC measurements by using this series of standard carriers to successively determine their TEC values.
