FIELD: glass products. SUBSTANCE: high-vacuum glass is preliminarily crushed and screened. Fraction with particle size less than 0.4 mm is subjected to vibration grinding. Resulting powder is converted into emulsion with polyethylene (molecular weight 12000-35000), which is then pulverized to produce powder. Prior to be pressed, the latter is supplemented with 0.05-0.4% zinc stearate. EFFECT: increased coefficient of shrinkage and mechanical strength of glass pellets. 1 tbl

Изобретение относится к производству изделий типа таблеток из электровакуумного стекла и обеспечивает высокий коэффициент усадки и механическую прочность стеклотаблеток. Способ получения пресс-порошка включает предварительное дробление стекла, просеивание и выделение фракции с предельным размером частиц <0,4 мм, последующий вибропомол, приготовление суспензии из стекла, в качестве связки применяют полиэтиленгликоль со средним молекулярным весом 12000 - 35000, и осуществляют распыление суспензии. В полученный стеклопорошок добавляют стеарат цинка в соотношении 0,05 - 0,4 % от массы пресс-порошка.The invention relates to the manufacture of products such as tablets from electrovacuum glass and provides a high shrinkage coefficient and mechanical strength of glass tablets. A method for producing a press powder includes preliminary crushing of glass, sieving and separation of a fraction with a limiting particle size of <0.4 mm, subsequent vibratory grinding, preparation of a suspension of glass, polyethylene glycol with an average molecular weight of 12,000 - 35,000 is used as a binder, and the suspension is sprayed. Zinc stearate is added to the obtained glass powder in a ratio of 0.05 - 0.4% by weight of the press powder.
