Description
372899 После полимеризации образец шлифуют и полируют обычными способами. Пример, 5 г порошка стиракрила и 3 г порошка алюминида никел смешивают с 8-10 мл жидкости дл полимеризации стиракрила. Полученную смесь заливают в обойму, установленную на магнитную плиту, включают магнитное поле с удельной силой прит жени 3 кг/см и осущест-вл ют полимеризацию смолы в течениею ЗО мин до полного ее отвердени .. Полученный образец шлифуют абразивными шкурками и полируют с использовацием окиси хрома. Осуществление процесса полимериза- is ции смолы в магнитном поле обеспечивает осаждение порошка на поверхности шлифа в количестве в 6-8 раз большем, чем при получении шлифа известным способом. Это позвол ет уменьшить количество из- 20 готовл емых шлифов дл металлографических исследований, что приводит к повыибнию производительности предложенного способа , . 34 ор мула.изобретен :и Способ изготовлени микрошлифо& из порошков магнитных материалов, вклрчающий смешивание порошка с быстротвердек щей акриловой смолой, заливку смесрн в обойму, полимеризацию смолы, шлифовку и полировку, отличающийс тем, что, с целью повышени произв|од№тельности ,полимеризацию осуществл Ьт в магнитном поле с удельной силой прит же ни 2-4 кг/см.i ; Источники информации,: прин тые во внимание при экспертизе : 1.

For example, 5 g of styracryl powder and 3 g of nickel aluminide powder are mixed with 8-10 ml of styracrylic polymerization liquid. The resulting mixture is poured into a holder mounted on a magnetic plate, including a magnetic field with a specific gravity of 3 kg / cm, and the resin is polymerized for 30 min. Until it is completely cured. chromium. The implementation of the process of polymerization of the resin in a magnetic field provides for the deposition of powder on the surface of the thin section in an amount of 6-8 times more than when a thin section is obtained in a known manner. This reduces the number of manufactured sections for metallographic studies, which leads to an increase in the productivity of the proposed method,. 34 ormula. Invented: and A method of making microsection & powders of magnetic materials, including mixing the powder with a quick-hardening acrylic resin, pouring the mixture into a holder, polymerizing the resin, grinding and polishing, characterized in that, in order to increase production, polymerization takes place in a magnetic field however, not 2-4 kg / cm; i; Sources of information: taken into account in the examination: 1.
