Известен способ изготовлени  активной массы дп  электродов аккумул тора путем резки синтетического волокна и смешивани  |его с„ исходными компонентами массы. I Синтетические волокна при резке ножами спекаютс  между собой в месте действи  . ножа, что приводит к необходимости введени  дополнительной операции расчесывани  волокон.There is a known method of making active mass dp of battery electrodes by cutting synthetic fiber and mixing it with the original mass components. I Synthetic fibers, when cutting with knives, are sintered among themselves at the site of action. knife, which necessitates the introduction of an additional combing operation.

Легкое, эластичное, склонное к перепле- тению и комкованию волокно при смешивании неравномерно распредел етс  в акти& ной массе, что снижает прочность электрода .The lightweight, elastic, tangled and clumping fiber, when mixed, is unevenly distributed in the active & mass, which reduces the strength of the electrode.

По предложенному способу с целью упрошени  технологии и повышени  механической прочности предлагаетс  перед резкой подвергать волокно переохлаждению до температуры стекловани .According to the proposed method, in order to simplify the technology and increase the mechanical strength, it is proposed to subcool the fiber to glass transition temperature before cutting.

При стекловании полимер волокна переходит из упруго-эластичного состо ни  в хрупко-стеклообразное. Степень стекловани  волокна можно определить руками на излом. Переохлажденное волокно хорошо рубитс , при этом спекание исключаетс . После рубки переохлажденное волокно смешивают с остальными компо11ентами. Если после резки волокно нагрелось до упруго-эластичного состо ни , то перед введением его пере охлаждают до состо ни  стекловани  или до состо ни , близкого к стеклованию.During glass transition, the polymer of the fiber changes from an elastic to a brittle-glassy state. The degree of fiberglass fiber can be determined by hands on a fracture. The supercooled fiber is well chopped, and sintering is eliminated. After chopping, the supercooled fiber is mixed with the remaining components. If, after cutting, the fiber is heated to an elastic-elastic state, before introduction it is re-cooled to a glass transition state or to a state close to glass transition.

В начальной стадии перемешивани  переохлажденное волокно не успевает нагречЬс  до такой степени, чтобы происходило его комкование, и равномерно распредел емс  в массе. В процессе дальнейшего перемешивани  комковани  не происходит, |раз- мер.отдельных волокон незначителен и они уже равномерно распределились в массе.In the initial stage of mixing, the supercooled fiber does not have time to heat to such an extent that its clumping occurs, and is evenly distributed in the mass. In the process of further mixing, the clumping does not occur, the size of the individual fibers is insignificant and they are already evenly distributed in the mass.

При изготовлении активной массы элект. родов свинцовых аккумул торов волокно ввод т и перемешивают до введени  серной кислоты.In the manufacture of active mass elect. of lead battery generators, fiber is introduced and mixed prior to the introduction of sulfuric acid.
