Description
тель. Последний вступает в химическую реакцию с гидролизованным этилсиликатом.tel. The latter enters into a chemical reaction with hydrolyzed ethyl silicate.
. В процессе химического твердени керамический слой формы (стержн ) преобретает полутвердое упругое состо ние. В этой стадий керамического сло извлекают модель из формы (стержень из стержневого щика) и производ т поджигание выдел юШЙЖй йз кёраййческого сло паров растворител . Одновременно в форму, в частности в глубокие ее ТОЛбСтй, подают сжатый воздух, который способствует равномерному и одновременному выгоранию в форме растворител , что предотвраш,ает по вление в керамике, в том числе и в глубоких полост х формы, сетки грубых трещин. Отсутствие последних приводит к повыщению размерной точности отливок.. In the process of chemical hardening, the ceramic layer of the form (rod) acquires a semi-solid elastic state. In this stage of the ceramic layer, the model is removed from the mold (core from the core box) and the separation of the ceramic layer of the solvent layer is ignited. At the same time, compressed air is supplied to the form, in particular, to its deep TOLBSTY, which contributes to the uniform and simultaneous fading in the form of a solvent, which prevents the formation of coarse cracks in the ceramics, including in deep cavities of the form. The absence of the latter leads to an increase in dimensional accuracy of castings.
