Description
Изобретение относитс к целлюлозно-бумажной промышленности. Оно может примен тьс при изготовлении и эксплуатации силовых кабелей и трансформаторов. Известна масса дл изготовлени стабили- 5 зированной изол ционной бумаги и картона, содержаща сульфитную небеленую целлюлозу и ингибитор. Недостаток такой бумажной массы заключаетс в том, что, изготовленные из нее бума- 10 га и картон не обеснечивают достаточную стабилизацию диэлектрических потерь. Целью насто щего изобретени вл етс расщиренне ассортимента ингибиторов, вводимых в массу способствующих стабилизации 15 диэлектрических потерь в процессе эксплуатации бумажпой изол ции в системе с минеральными нефт ными маслами. Это достигаетс введением в сульфатную небеленую целлюлозу силикагел в количе- 20 стве 0,5-5% от веса абсолютно сухого волокна . Использова И1е в качестве ингибитора снлнкагел нозвол ет стабилизировать диэлектрические характеристики изол ционной бумаги 25 при искусственном старении ее в электроизол ционных нефт ных маслах, приведенные ниже в таблице. Таблица Образцы кабельной бумаги изготовл ют из сульфатной небеленой целлюлозы ЗИ-1 весом -100+2 г. Нанолнитель даетс в начале 1 размола. Режим искусственного старени заключаетс в следующем. Образцы, помещенные в стаканы из кварцевого стекла, сушатс и пропитываютс дегазированным мас.юм С-220, в результате чего они при температуре 120°С в течение 300 час п вакуум-сунп-кизпом ипикЬ} с остаточным давлением 1-2 .м рт. ст. 3 Предмет изобретени Бумажна масса дл изготовлени стабилизированной изол ционной бумаги и картона, содержаща сульфатную небеленую целлю- 5 лозу и ингибитор, отличающа с тем, что, с 4 целью стабилизации диэлектрических потерь в процессе эксплуатации бумажной изол ции в системе с минеральными нефт ными маслами , в качестве ингибитора масса содержит 0,5-5% силикагел от веса абсолютно сухого волокна.The invention relates to the pulp and paper industry. It can be used in the manufacture and operation of power cables and transformers. A known mass for the manufacture of stabilized insulating paper and cardboard, containing sulphite unbleached pulp and an inhibitor. The disadvantage of such paper pulp is that the paper and cardboard made from it do not ensure sufficient stabilization of the dielectric losses. The aim of the present invention is to extend the range of inhibitors introduced into the mass which contribute to stabilizing the 15 dielectric losses during the operation of paper insulation in the system with mineral petroleum oils. This is achieved by introducing into the unbleached sulphate cellulose silica gel in an amount of 0.5-5% by weight of absolutely dry fiber. The use of Ile as a snlnkagel inhibitor makes it possible to stabilize the dielectric characteristics of insulating paper 25 upon its artificial aging in electrical insulating oil oils, which are given in the table below. Table Samples of cable paper are made from ZI-1 sulphate unbleached pulp weighing -100 + 2 g. The filler is given at the start of 1 grinding. The mode of artificial aging is as follows. Samples placed in quartz glasses were dried and impregnated with a degassed mash of C-220, resulting in them at a temperature of 120 ° C for 300 hours with vacuum suction cup with a residual pressure of 1-2 m. . Art. 3 Subject of the invention Paper pulp for the manufacture of stabilized insulating paper and cardboard, containing sulphate unbleached cellulose and an inhibitor, characterized in that, with the 4 aim of stabilizing the dielectric losses during the operation of the paper insulation in a system with mineral oil oils, as an inhibitor, the mass contains 0.5-5% silica gel by weight of absolutely dry fiber.
