Description

Известна бумага дл  сепараторов щелочных аккумул торов, также известно применение дл  сепараторов капронового и асбестового волокна.Known paper for alkaline battery separators, it is also known to use nylon and asbestos fiber for separators.

Однако, известна  бумага дл  сепараторов имеет недостаточно хорошее качество и значительную стоимость, стоимость капронового волокна еще выше. Бумага дл  сепараторов щелочных аккумул торов, изготовленна  согласно изобретению, лишена этих недостатков. Сущность изобретени  заключаетс  в том, что предложенна  бу.мага изготавливаетс  из 60% капронового и 40% асбестового волокна, проклеенных спиртораствори.мым полиамидом.However, the well-known paper for separators has insufficient quality and considerable cost, the cost of nylon fiber is even higher. The paper for alkaline battery separators made according to the invention does not have these disadvantages. The essence of the invention is that the proposed paper is manufactured from 60% nylon and 40% asbestos fibers, glued with an alcohol-soluble polyamide.

Дл  изготовлени  капроновое волокно беретс  с номером элементарного волокна 2100 и выше и длиной резки 35 мм, а асбест - длинноволокнистый , предварительно обработанный щелочью. Волокниста  смесь капрона и асбеста тщательно расчесываетс  на вак -умформующей машине и получаетс  бумажное полотно с мелкой пористостью, которое проклеиваетс  1%-ным раствором поливинилового спирта и высушиваетс . Затем бумага обрабатываетс  (проклеиваетс ) спирторастворимым полиамидом на пропиточном станке с двум  пропиточными ваннами , прессом и сушильны.м устройством.For the manufacture of nylon fiber is taken with the number of elementary fibers 2100 and above and a cutting length of 35 mm, and asbestos - long-staple, pre-treated with alkali. The fiber mixture of caprone and asbestos is thoroughly combed on a vacuum forming machine and a paper web with fine porosity is obtained, which is glued with a 1% solution of polyvinyl alcohol and dried. The paper is then processed (glued) with an alcohol-soluble polyamide on an impregnating machine with two impregnating baths, a press and a dryer.

Перва  пропитывающа  ванна обогреваетс  глухим паром. В нее заливаетс  спиртовый раствор полиамида. Пропитка полотна производитс  при температуре 60-80°, затем отжимаетс  на прессе от избытка св зующего вещества и поступает во вторую-коагул ционную ванну , наполненную дистиллированной водой или конденсатом. После этого полотно отжимаетс  и просушиваетс  при температуре 120-130°. В случае необходимости готова  бумага подвергаетс  легкому каландрированию на гор чих валах при температуре 100-120°.The first impregnation bath is heated by dumb steam. An alcoholic solution of polyamide is poured into it. The fabric is impregnated at a temperature of 60-80 °, then is pressed on the press from an excess of binder and enters the second coagulation bath filled with distilled water or condensate. After that, the web is pressed and dried at a temperature of 120-130 °. If necessary, the prepared paper is subjected to light calendering on hot shafts at a temperature of 100-120 °.

№ 143848 2Одна из особенностей примененной пропитки полиамидом состоит в том, что дл  повышени  объемного сопротивлени  материала до 1.102 ож. см полиамидную крошку до растворени  в спирте нужно подвергнуть 3-4-кратному экстрагированию кип щей водой и сушке гор чим воздухом при температуру 80-100°.No. 143848 2One of the features of the polyamide impregnation used is that in order to increase the volume resistance of the material to 1.102 ozh. See polyamide crumbs before dissolving in alcohol should be extracted 3-4 times with boiling water and dried with hot air at a temperature of 80-100 °.

Проведенные лабораторные испытани  показали, что полученна  бумага устойчива к длительному действию щелочей аккумул торов.Conducted laboratory tests showed that the paper obtained was resistant to the long-term effect of alkalis of batteries.

Предмет изобретени Subject invention

Бумага дл  сепараторов щелочных аккумул торов, отличающа с  тем, что, с целью улучшени  качества и снижени  стоимости изготовлени  сепараторов, бумага изготавливаетс  из 60% капронового и 40% асбестового волокна, проклеенного спирторастворимым полиамидом .Paper for alkaline battery separators, characterized in that, in order to improve the quality and reduce the cost of manufacture of separators, paper is made from 60% nylon and 40% asbestos fibers, glued with soluble polyamide.
