Abstract
Изобретение относитс к способам получени волластонита, используемого в качестве сырь дл производства высококачественной керамики, фарфоровой посуды, акустических плиток, в качестве добавки при производстве пластмасс, эластомеров, феноловых смол, и позвол ет повысить чистоту продукта при сохранении его высокой белизны. Смешивают кварцевый песок, карбонат кальци , окись магни и CAO, причем CAO берут в количестве 15,5 - 19,9 мас.% от общей массы шихты и затем провод т обжиг смеси при 1280 - 1300°С. 2 табл.The invention relates to methods for producing wollastonite used as a raw material for the production of high-quality ceramics, porcelain dishes, acoustic tiles, as an additive in the production of plastics, elastomers, phenolic resins, and allows for increasing the purity of the product while maintaining its high whiteness. Quartz sand, calcium carbonate, magnesium oxide, and CAO are mixed, and the CAO is taken in an amount of 15.5–19.9% by weight of the total mass of the mixture, and then the mixture is calcined at 1280–1300 ° C. 2 tab.
Description
Изобретение относитс к способам получени волластонита, используемого в качестве сырь дл производства высококачественной керамики фарфоровой посудч акустических плиток, в качестве добавки при производстве ппастмасс, эластомеров феноловых смолThe invention relates to methods for producing wollastonite, used as a raw material for the production of high-quality ceramics of porcelain saucer, acoustic tiles, as an additive in the production of pastes, phenol resin elastomers.
Целью изобретени вл етс повышение чистоты продукта при сохранении его высокой белилныThe aim of the invention is to increase the purity of the product while maintaining its high quality.
П р и м е р. 53 г измельченного кварцевого песка смешивают с 45 г измельченного известн ка, добавл ют 25 г гашеной извести в количест ее 19,9 мае % от массы шихты, добавл ют 1,5 мас.% (от смеси) МдОтех (доломит ), шихту перемешивают и обжигают пои 1300°С в течение 30 минPRI me R. 53 g of crushed silica sand are mixed with 45 g of crushed lime, 25 g of hydrated lime are added in the amount of 19.9% by weight of the charge, 1.5% by weight (from the mixture) of MDOtech (dolomite) are added, the mixture is mixed and burn poi 1300 ° C for 30 min
Химический анализ продукта показал отсутствие СаОсв. Рентгенограмма образца хорошо согласуетс с данными высокотемпературного волластонита ( а-СаЗЮз) ИК- спектр поглощени данного образца идентичен спектру а-СаЗЮзChemical analysis of the product showed the absence of CaOs. The radiograph of the sample is in good agreement with the data of high-temperature wollastonite (a-CASUz). The IR absorption spectrum of this sample is identical to the spectrum of a-CASU3.
Белизна продукта не менее 85% по отношению к эталонуThe whiteness of the product is not less than 85% relative to the standard
Результаты остальных ОПЫТОЕ представлены в таблицеThe results of the rest are experienced in the table.
По прототипу получают продукт, не содержащий свободного СаО с белизной 85%, содержащий в качестве примесей 0,1-0,5 мае % или N320The prototype receive a product that does not contain free CaO with a whiteness of 85%, containing as impurities 0.1-0.5 May% or N320
Повышение чистоты продукта по предложенному способу достигаетс за счет ис- ключени загр знени его окислами щелочных металловAn increase in the purity of the product according to the proposed method is achieved by eliminating its contamination with oxides of alkali metals.
