Measuring the propensity of a material to acquire an electrostatic charge

Measuring the propensity of a material to acquire an electrostatic charge

The propensity of a material (eg textile) to pick up electrostatic charge is measured by rubbing a sample S of the material and then sensing the induced electrostatic voltage. A rubbing unit 10, 11 and extendable pedestal 9 enable the rubbing action and a sample table 16 then carries the sample S to...

Zusammenfassung:The propensity of a material (eg textile) to pick up electrostatic charge is measured by rubbing a sample S of the material and then sensing the induced electrostatic voltage. A rubbing unit 10, 11 and extendable pedestal 9 enable the rubbing action and a sample table 16 then carries the sample S to a measuring position beneath an electrostatic voltage sensor 13. A data processor (3, Figure 8) controls the measuring operation and processes the data obtained. ……
