Description
Известные электроизол ционные бумаги на основе модифицированной целлюлозы обладают низкой нагревостойкостью.The known electrically insulating papers based on modified cellulose have low heat resistance.
Дл повышени нагревостойкости бумаги предлагаетс волокниста масса, содержаща борилированную целлюлозу. При этом бумагу вырабатывают как из 100% борилированной целлюлозы, так и в композиции с сульфатной небеленой целлюлозой; используема борилированна целлюлоза содержит 6-8 вес. % бора.To increase the heat resistance of the paper, a fibrous mass containing boronated cellulose is proposed. At the same time, paper is produced both from 100% borylated cellulose, and in composition with unbleached sulphate pulp; Used borilated cellulose contains 6-8 wt. % boron.
Пебеленую сульфитную целлюлозу обрабатывают смесью тетрабората натри и мочевины или смесью борной кислоты и мочевины.The white sulphite pulp is treated with a mixture of sodium tetraborate and urea or a mixture of boric acid and urea.
Затем борилированную целлюлозу размалывают до степени помола 97-98° ШР и изготавливают конденсаторную бумагу.Then borilated cellulose is ground to the degree of grinding 97-98 ° SHR and make capacitor paper.
Бумага, изготовленна из массы описываемого состава, обладает повышенной нагревостойкостью .Paper made from the mass of the described composition has a high heat resistance.
