Известна паста дл  положительного электрода свинцового аккумул тора, содержаща  окислы свинца, серную кислоту и фторопласт, например, марки 4Д, который ввод т в пасту в виде порошка. Недостатком такой пасты  вл етс  низкий коэффициент ее использовани  и небольшой срок службы. с)то объ сн етс  тем, что фторопласт, служащий св зующим л порообразователем, комкуетс  и неравномерно распредел етс  по всей массе также из-за большой разности удельных весов окислов свинца и фторопласта.A known paste for a positive electrode of a lead battery, containing lead oxides, sulfuric acid and a fluoroplastic, for example, brand 4D, which is introduced into the paste in the form of a powder. The disadvantage of such a paste is a low coefficient of its use and a short service life. c) This is due to the fact that the fluoroplastic, which serves as a binding agent for the pore-forming agent, is crumpled and unevenly distributed throughout the whole mass, also due to the large difference in the specific weights of lead oxides and fluoroplastic.

Дл  повышени  срока службы и коэффициента использовани  в предлагаемую naciy фторопласт введен в виде его водной суспенз ,ии.In order to increase the service life and utilization ratio, the proposed naciy fluoroplastic is introduced in the form of its aqueous suspension, ai.

Водна  суспензи  фторопласта марки 4Д  вл етс  продуктом капельной полимеризации тетрафторэтилена в водной среде. Дл  улучшени  эмульгировани  мономера и повышени  стабильности эмульсии в сторону добавл ют поверхностно-активное вещество, ко горое в дальнейшем, после проведени  процесса полимеризации удерживает гранулы нол;;мера в воде во взвешенном состо нии. Величина гранул не превышает 0,5 мкм. Они эластичны , клейки и при разрушении сталилизатора суспензии коагулируют, образу  однородную клейкую массу. Полимер ни в чем не раствор етс  ,и обладает высокой химической стойкО|Стью к действию кислот, щелочей и органических растворителей.Aqueous suspension of fluoroplastic grade 4D is the product of droplet polymerization of tetrafluoroethylene in an aqueous medium. To improve the emulsification of the monomer and to increase the stability of the emulsion, a surfactant is added to the side, which later, after carrying out the polymerization process, keeps the granules to zero ;; the measure in water is suspended. The size of the granules does not exceed 0.5 microns. They are elastic, gluing, and when the stalyizer is destroyed, the suspensions coagulate, forming a uniform adhesive mass. The polymer does not dissolve in anything, and has a high chemical resistance to acids, alkalis and organic solvents.

При изготовлении пасты водна  суспензи  фторопласта подаетс  из жидкостного дозатора в свинцовый порошок или порошкообразные окислы свинца ,и равномерно распредел етс  по всей массе. Равномерность распределени  суспензии обеспечиваетс  наличием в ней поверхностно-активного вещества и сравнительно небольшими размера.ми гранул. При перемешивании массы защитна  лленка стабилизатора разрушаетс  и гранулы полимера оседают на частицах свинца, склеиваютс  одна с другой и образуют эластичный каркас при намазке электрода. В дальнейшем каркасудерживает пасту от оплывани . Кроме того,In the manufacture of the paste, the aqueous suspension of fluoroplastic is supplied from the liquid dispenser to the lead powder or powdered lead oxides, and is evenly distributed throughout the mass. The uniform distribution of the suspension is ensured by the presence of a surfactant and relatively small size of the granules. When the mass is mixed, the stabilizer's protective film collapses and the polymer granules settle on the lead particles, stick together with each other and form an elastic frame when the electrode is spread. Subsequently, the framework holds the paste from being swollen. Besides,

электрод с такой пастой мало набухает и более прочен. Благодар  этому практически полностью устран ютс  короткие замыкани  через прорастание сепараторов и отпадает необходимость применени  двойной сепарацииelectrode with such a paste swells little and more durable. Due to this, short circuits through the germination of separators are almost completely eliminated and there is no need to use double separation.

при сборке аккумул тора. Срок службы при этом увеличиваетс  на 30-40%.when assembling the battery. The lifetime is increased by 30-40%.
