(5) СПОСОБ ИЗГОТОВЛЕНИЯ (5) METHOD OF MANUFACTURE
АБРАЗИВНОГО ИНСТРУМЕНТАABRASIVE TOOLS
1one
Изобретение относитс к изготовлению абразивного инструмента.The invention relates to the manufacture of an abrasive tool.
Известна абразивна масса, содерх жаща абразив, керамическую св зку, увлажнитель, клеющую добавку и временное св зующее, в которую с целью повышени прочности свежезаформованного и высушенного издели в качест ,ве временного св зующего ввод т 1535 -ный водный раствор сополимера ме.тилметакрилата с натриевой солью метакриловой кислоты 13.A known abrasive mass containing an abrasive, ceramic bond, humidifier, adhesive additive and temporary binder, into which, in order to increase the strength of the freshly molded and dried product, a 1535% aqueous solution of methyl methacrylate copolymer is introduced as a temporary binder. sodium salt of methacrylic acid 13.
При обжиге изделий из указанной массы происходит разложение и выгорание введенного сополимера, что влейет за собой нарушение локальной структуры в упаковке абразивных зерен и приводит к понижению эксплуатационных свойств получаемого инструмента . Кроме того, при выгорании и разложении сополимера наблюдаетс повышенна загазованность атмосферы, что требует дополнительной герметизации существующего термического оборудовани и корректировки режимов термообработки.When firing products from the specified mass, decomposition and burning of the introduced copolymer occurs, which will lead to a violation of the local structure in the packaging of abrasive grains and leads to a decrease in the performance properties of the resulting tool. In addition, when the copolymer burns out and decomposes, the atmosphere becomes more polluted, which requires additional sealing of the existing thermal equipment and adjustment of heat treatment conditions.
Известен также технологический процесс изготовлени абразивного инструмента, при котором абразивна масса, содержаща абразивное зерно, керамическую св зку, жидкое стекло, после перемешивани и прессовани подвергаетс насыщению углекислотой при покощи различных устройств от балонов со сжатым газом. При химическом взаимодействии углекислоты с жидким стеклом происходит отверждение стекла и, как следствие, уппрочнение сырца заготовки 2.Also known is the process of making an abrasive tool, in which the abrasive mass containing abrasive grains, ceramic binder, water glass, after mixing and pressing, is saturated with carbon dioxide while various devices from compressed gas cylinders are poured. In the chemical interaction of carbon dioxide with liquid glass, the glass is cured and, as a result, the raw material is strengthened 2.
Недостатком такого способа вл етс усложнение технологического The disadvantage of this method is the complication of technological
20 . процесса изготовлени абразивного инструмента.20 . abrasive tool making process.
Цель изобретени - упрощение техпроцесса отверждени жидкого стекла.The purpose of the invention is to simplify the process of solidification of liquid glass.
