Method for preparing methyl silicate |
| abstract |
The invention relates to the production of ceramic casting molds in melted models. The purpose of the invention is to increase the binding properties of the subsequent hydrolysis and stability of the strength characteristics of ceramics based on it. Ethyl silicate is prepared by treating it with an alkali metal hydroxide in the amount of 0.05-0. , 5% of the mass of ethyl silicate in the form of a 5–15% solution and keeping it for 2 50 hours. The introduction of an alkali metal hydroxide into ethyl silicate leads to a catalytic rearrangement with remaining CPMPHO ethyl silicate, as hydroxides actively absorb on the processes of disproportionation of oligoethoxy siloxanes Flexural strength of raw samples 5.0 5.3 MPa, and calcined 7.4-7.9 MPa The invention stabilizes the technological processes of manufacturing ceramic forms and use ethyl citrus-40 from various plants.
