Description
(5k) СПОСОБ ИЗГОТОВЛЕНИЯ ЭЛЕКТРОИЗОЛЯЦИОННОЙ Изобретение относитс к целлюлозно-бумажной промышленности, в частности к изготовлению электроизол ционной бумаги. Известен бумажный диэлектрик, содержащий в качестве сорбента природный алюмосиликат, в котором ионы щелочных металлов замещены ионами двух- и трехвалентных металлов D . . Однако при проведении ионообменной реакции замещени в суспензии алюмосиликата вытесненные ионы остаютс в жидкой фазе системы, и введение такой суспензии непосредственно в бумажную массу повышает диэлектри ческие потери бумажного диэлектрика Поэтому тверда фаза суспензии алюмосиликата при такой обработке долж на быть выделена и тщательно отмыта как от ионов, вытесненных из минерала , так и от водорастворимых солей , которые об зательно присутствуют в природных алюмосиликатах и(5k) METHOD OF MANUFACTURING ELECTRICAL INSULATION The invention relates to the pulp and paper industry, in particular to the manufacture of electrical insulation paper. Known paper dielectric containing as a sorbent natural aluminosilicate, in which alkali metal ions are replaced by ions of divalent and trivalent metals D. . However, when carrying out an ion exchange substitution in an aluminosilicate suspension, the displaced ions remain in the liquid phase of the system, and the introduction of such a suspension directly into the paper pulp increases the dielectric losses of the paper dielectric. displaced from the mineral and from water-soluble salts, which are necessarily present in natural aluminosilicates and
БУМАГИ повышают тангенс угла диэлектрических потерь бумаги с таким сорбентом. Известен способ изготовлени электроизол ционной бумаги, например конденсаторной, включающий очистку от примесей сорбента - природного алюмосиликата, введение его в бумаж- . ную массу и отлив полотна. Очистку алюмосиликата от примесей осуществл ют путем пропуска суспензии алюмосиликата через слой катионитовой смолы в Н-форме 2}. Однако така очистка позвол ет удалить только катионы катионно-обменного комплекса самого минерала, но не удал ет водорастворимые ионные примеси, и, следовательно, не обеспечивает снижение тангенса угла диэлектрических потерь. Цель изобретени - снижение тангенса угла диэлектрических потерь. - Ухааанна цель достигаетс тем, что согласно известному способу изготовлени электроизол ционной бумаг,PAPERS increase the dielectric loss tangent of paper with such a sorbent. A known method of manufacturing an electrically insulating paper, such as a capacitor paper, involves cleaning the sorbent, a natural aluminosilicate, from impurities and introducing it into the paper. the mass and flow of the canvas. Purification of aluminosilicate from impurities is carried out by passing a suspension of aluminosilicate through a layer of cation resin in the H-form 2}. However, this cleaning only removes the cations of the cation-exchange complex of the mineral itself, but does not remove the water-soluble ionic impurities, and, therefore, does not reduce the dielectric loss tangent. The purpose of the invention is to reduce the dielectric loss tangent. - The goal is achieved by the fact that, according to the known method of making electrically insulating papers,
