Description
Известен электроизол ционный материал- плавлена окись магни , примен емый дл изол ции нагревательной спирали от оболочки трубчатого электронагревател СЗднако плавлена окись магни имеет недостаточно высокую электрическую прочность и сопротивление при высоких температурах, а также недостаточно высокую влагостойкость.A known electrical insulation material is fused magnesium oxide used to isolate the heating coil from the shell of a tubular electric heater. However, fused magnesium oxide does not have sufficiently high dielectric strength and resistance at high temperatures, as well as not enough moisture resistance.
Целью изобретени вл етс повып1ение изол ционных свойств и влагостойкости. Дл этого в плавленую окись магни введен карбонитрид бора, предпочтительно в количестве вес. %.The aim of the invention is to develop the insulation properties and moisture resistance. For this, boron carbonitride is introduced into the fused magnesium oxide, preferably in an amount of weight. %
Карбонитрид бора в виде порошка, предпочтительно с размерами частиц не более 0,1 МЛ1, смешивают с плавленой окисью магни , также наход щуюс в виде порошка, предпочтительно с размерами частиц не более 0,5 мм.Boron carbonitride in powder form, preferably with a particle size of not more than 0.1 ML1, is mixed with fused magnesium oxide, also in powder form, preferably with a particle size of not more than 0.5 mm.
Предложенный материал имеет существенно более высокую электрическую прочность и опротивление при высоких температурах, чем плавлена окись магни ; материал также менее чувствителен к воздействию влажной атмосферы .The proposed material has a significantly higher dielectric strength and resistance at high temperatures than fused magnesium oxide; The material is also less sensitive to the effects of a humid atmosphere.
