Description
СПОСОБ ОПРЕДЕЛЕНИЯ КРАТНОСТИ ЛАТЕКСНОЙ ПЕНЫMETHOD FOR DETERMINING THE LATEX FOUNDATION BRIEF

Изобретение -относитс к контролю качества полимерных материалов, например латексных пен.The invention relates to quality control of polymeric materials, for example latex foams.
Известен способ определени кратности пен путем определени соотношени злектропроводимости смеси и пены. Этот способ не обеспечивает достаточной точности измерени .There is a method for determining the multiplicity of foams by determining the ratio of the electrical conductivity of the mixture and the foam. This method does not provide sufficient measurement accuracy.
Дл повышени точности измерени предлагаетс определ ть соотношение комплексных проводимостей ,в диапазоне частот переменного тока 1-50 мгц. По предлагаемому способу одновременно определ1 ют удельную электропроводимость и диэлектрическую проницаемость , т. е. комплексную проводимость пены и латексной смеси, по соотношению которых суд т о кратности пены.In order to increase the measurement accuracy, it is proposed to determine the ratio of complex conductances in the frequency range of alternating current of 1-50 MHz. The proposed method simultaneously determines the specific conductivity and dielectric constant, i.e., the complex conductivity of the foam and the latex mixture, the ratio of which determines the multiplicity of the foam.
Один из датчиков устанавливают на трубопровод , -по (KiOTOipOiMy течет латексна смесь.One of the sensors is installed on the pipeline, -po (KiOTOipOiMy flows latex mixture.
а другой - «а трубопровод, по которому течет шена. Соотношение показаний этих датчиiKOiB дает И|3ме|р вмую величину кратности пеиы . Измерение комплексной Проводи мости латеконой смеси и -пены позвол ет П;роводить контроль безконтаа тным способом, что исключает налипание латекса на электроды и повышает его точность.and the other, “and the pipeline through which the Shen flows. The ratio of the readings of these sensors to iKOiB gives And | 3me | p is the magnitude of the multiplicity of the pipe. Measurement of the complex conductivity of the latecone mixture and foam makes it possible to carry out the P; to conduct the control in a non-contact manner, which eliminates sticking of the latex on the electrodes and increases its accuracy.
