Изобретение относитс к литью по выплавл емым моделЯМ и быть использовано дл увеличени прочности этилсиликатиых керамических форм при нракаливаHHIH .The invention relates to casting on melted models and to be used to increase the strength of ethyl silicate ceramic forms with HHIH.
Известел раствор дл повышени- качества форм, включа.ющий 2%-ный водный раствор сол ной кислоты. Однако вследствие образовани сетки мик,ро- и мак|ротрещн1Н формы, обработан.иые указанным растворо м, имеют инзкую механическую прочность при прокалив а-нии.The solution was known for improving the quality of the forms, including an aqueous 2% hydrochloric acid solution. However, due to the formation of a mesh, the mic, ro-, and macrostocrescent forms, treated with these solutions, have an intangible mechanical strength during calcination of a-nii.
Предлагаемый раствор позвол ет значительно повысить прочность форм при их прокаливадиИ . Это достигаетс тем, что в состав 2%-1Ного водного раствора сол ной кислоты введен хлорид щелочиоземельного -металла, например хлористый кальций, при следующем соотношении коМ|ПО«ентов (в вес. %): 2%-ный водный раствор сол йой кислотыОсноваThe proposed solution allows to significantly increase the strength of the forms when they are calcined. This is achieved by adding alkaline earth metal chloride, for example, calcium chloride, to a 2% -1N aqueous aqueous solution of hydrochloric acid in the following ratio of comm | 2% aqueous solution of hydrochloric acid.

При пракалива1НИ1И форм, обработанных описываемым раствором, прои-сх-одит образова1ние те|рмоустойчиЕых кальциевосиликатных соединеадий, имеющих мемьщее линейное расширение , а хлориды мелаллов, не вступивщие в реакцию с аморф|ным гелем кре-мнезема ил-и другим св зующим основы форумы, при температуре выше расплавл ютс , заполн ют M Kipo- и ма«ротрещины в фор-мах и самым цементируют их, увеличива прочность и улучша качество форм.During the treatment of the forms treated with the solution described, the formation of heat-resistant calcium-silicate compounds, which have linear linear expansion, and the chlorides of the metal, which did not react with the amorphous gel with silica gel and other relevant bases, will form at temperatures above, they melt, fill the Kipo- and my fractures in the molds and cement them most, increasing strength and improving the quality of the molds.
