(54) -СПОСОБ ИЗГОТОВЛЕНИЯ ИЗВЕСТКОВО-КРЕМНЕЗЕМИСТЫХ- ТЕПЛОИЗОЛЯЦИОННЫХ (54) - A METHOD FOR MANUFACTURING LIMESTONE-SILICON-THERMAL INSULATED
12 ИЗДЕЛИЙ12 PRODUCTS
обраэователь дополнительно измельчают смесь до удельной поверхности 67009700 см /г, затвор ют водой, формуют издели и подвергают автоклавной обработке .The former additionally crushed the mixture to a specific surface of 6,7009700 cm / g, closed it with water, molded the product and subjected to autoclave treatment.
Конкретные примеры и свойства полученногб материала представлены в таблице,Specific examples and properties of the resulting material are presented in the table,
Предлагаемый способ позвол ет получить теплоизол ционный материал, приближающийс по объемной массе и теплотехническим свойствам к наиболее эффективным органическим материгшам и обладающий преимуществом по температуростойкости и огнестойкости, а также имеющий пониженную материалоемкость по сравнению с издели ми из теплоизол ционного чеистого бетона.The proposed method makes it possible to obtain a heat insulating material approaching in bulk mass and heat engineering properties to the most effective organic materials and having the advantage in temperature resistance and fire resistance, as well as having lower material consumption compared with products made from heat insulating cellular concrete.

Источники информации, прин тые во внимание при экспертизе 1. Авторское свидетельство СССР по за вке №2198797/29-33, кл. С 04 В 21/02, 1975.component 4000 Nexa lime, gypsum, 10% silica component and slag.,. 6000 Mix of all components 6700 Bulk weight of cellular concrete, kg / m 150 Compressive strength, MPa 0.6 Coefficient of crushed material 23C equal to 0.04. Invention Method for manufacturing lime-silica thermal insulation products by preparing raw materials by hydrating a part of lime, grinding the siliceous component to a specific surface of 4,000-5,000 cm / g, grinding out quicklime, slag and gypsum to a specific surface of 6,000 to 6,500, mixing all the components, forming articles and autoclaving Their work, characterized in that, in order to increase the strength of products, 15-30 wt.% of lime is hydrated from its total amount to fluff condition, 89-95% of the silica component is crushed, the rest of it is crushed together with quicklime, slag and gypsum, and after mixing the bulk components, the mixture is further crushed to a specific surface area of 67009700.
