SU91629A1 - Method for the production of silicate building products - Google Patents

Description

Usually, brick of silicates, silicate regions, acidic slabs and other building materials are made by welding pressed lime-sand mixture in steam boilers (aeTOKTaBaxI in P | p1) for 8-10 hours at the pressure, and napia in the boiler 8-9 atm.

The dryness of the proposed method consists in the production of silicate products without an ABT (chemical method, by adding to the dry, ordinary: sandy-sandy mixture (90% of quartz sand and 10% of lime) 5–7% granulated dry sodium silicate, sulfate, or soda, and then shut off: and this carefully peregM; yes Mass in the mass of 7-8% of the total weight of the mixture.

From the obtained wet silicate material, it is molded by pressing at a pressure of 180–200 kg / cm — the required products (bricks, slabs, etc.), which are then steamed in 8–10 hours. In addition, the vapor pressure is 1.0-1.1 atm in a steam chamber of a lane, ididic or continuous, after which the products acquire the required standard 1mexical durability and (Can be used.

The property of the proposed method lies in the fact that it excludes the use of autoclave kotlyuv, economy, and consumption on the basis of fuel: on, on, and allows the possibility of pr: and: me / n steaming chambers of continuous operation.

Subject invention

The method is made up of silicate streams, characterized in that a granulated dry sodium silicate is added to the dry lime-green mixture, the mixture is water-sealed and the articles are molded: steamed.
