Abstract (English):
Liquid glass is widely used in various industries due to its unique properties, such as high chemical resistance, adhesion, permeability and the ability to form strong silicate compounds. The main areas of application are mechanical engineering, pulp and paper, chemical and petrochemical industries, as well as in the production of building materials. Quartz sand is used as a raw material for the production of liquid glass. Alternative sources of silica, such as flask, are of interest from the point of view of resource conservation. The main criterion for the suitability of raw materials is a high content of amorphous SiO₂ and a minimum content of impurities. In the presented work, the possibility of obtaining liquid glass based on natural siliceous raw materials - flask of the Taskalinsky deposit, located in the West Kazakhstan region of the Republic of Kazakhstan. Flask is a sedimentary rock of siliceous origin with high porosity, adsorption activity and content of amorphous silicon dioxide, which makes it a promising raw material for chemical processing. The study included comprehensive physicochemical analyses of the source material: the chemical and mineralogical composition, silica content, clay components, and physicomechanical parameters were determined. Based on the results of X-ray phase analysis, it was found that the main components of the rock are opal, clay minerals, quartz, and minor impurities of calcite and organogenic residues. The chemical composition showed a SiO₂ content of 70-78%, which meets the requirements for raw materials for producing liquid glass. The process of alkaline treatment of flask using 20% solutions of sodium and potassium hydroxide was experimentally studied. The temperature and time parameters affecting the completeness of silica dissolution were studied. It was found that at a temperature of 95-98 °C and a duration of 2-3 hours in a raw material:alkali ratio of 1:2, the best result in terms of the yield of liquid glass with a silicate modulus within the standard values is achieved. The resulting product has undergone quality assessment according to the main parameters: density, SiO₂ and Na₂O/K₂O content, pH, silicate modulus. All parameters comply with the requirements of GOST 13078-81. Thus, the Taskalinskoye deposit flask can be effectively used as a raw material for the production of liquid glass, which is confirmed by laboratory tests and a feasibility study of the process.
