Description

Изобретение относитс  к способам определени  злектрическото сопротивлени  листового и рулонного диэлектрических материалов, в частности полимерных покрытий дл  полов.The invention relates to methods for determining the electrical resistance of sheet and rolled dielectric materials, in particular polymeric floor coverings.

Известен способ определени  сопротивлени , при котором плоский образец заданных размеров зажимаетс  между плоскими измерительными электродами, измер етс  ток при оиределенном напр жении на электродах и по его величине определ етс  сопротивление образца .A known method for determining resistance, in which a flat sample of a given size is clamped between flat measuring electrodes, the current is measured at the determined voltage on the electrodes and the resistance of the sample is determined from its value.

Однако такой способ неприменим дл  многослойных неоднородных композиций с тисненной или ворсистой поверхностью, кроме того, известный способ не обеспечивает непрерывного бесконтактного измерени  сопротивлени  движущихс  лент.However, this method is not applicable for multilayer inhomogeneous compositions with an embossed or fuzzy surface, in addition, the known method does not provide continuous non-contact measurement of the resistance of moving belts.

Цель изобретени  - измерение сопротивлени  многослойных неоднородных композиций.The purpose of the invention is to measure the resistance of multilayer inhomogeneous compositions.

Это достигаетс  тем, что по предлагаемому способу исследуемый материал помещают в зону коронного разр да между измерительными электродами и дважды измер ют разр дные токи, протекающие через указанный разр дный пpOJмeжyтoк и идентичный промежуток без материала при одинаковом приложенном напр жении, и по отнощению этих токов определ ют величину сопротивлени  исследуег гых образцов.This is achieved by the fact that according to the proposed method, the material under study is placed in the corona discharge zone between the measuring electrodes and the discharge currents flowing through the discharge discharge and the identical gap without material with the same applied voltage are measured twice and with respect to these currents The magnitude of the resistance of the test samples.

Внесение образца в зону коронного разр да вызывает уменьщение напр жени  на разр дном промежутке на величину падени  напр жени  на образце, равную произведениюThe introduction of the sample into the corona discharge zone causes a decrease in the voltage on the discharge gap by an amount of voltage drop on the sample equal to the product

разр дного тока на сопротивление образца. При этом разр дный ток уменьщаетс  по сравнению с током, проход щим через идентичный разр дный промежуток без образца при одинаковом приложенном напр жении. Отнощение этих токов однозначно определ ет величину падени  напр жени  к разр дному току , протекающему через образец, дает величину сопротивлени  образца.discharge current to sample resistance. In this case, the discharge current is reduced compared with the current passing through an identical discharge gap without a sample with the same applied voltage. Ratio of these currents uniquely determines the magnitude of the voltage drop to the discharge current flowing through the sample, gives the value of the resistance of the sample.
