DEVELOPMENT OF A QUANTITATIVE ANALYSIS OF SMALL QUANTTITIES OF ORGANIC COMPONENTS WITH THEIR JOINT CONTENT IN THE COMPOSITION OF A BINDER FOR CERAMIC SUSPENSIONS
A method has been developed for the quantitative analysis of a wetting agent, antifoam and an adhesive component, which are in the form of a mixture in a binder for the manufacture of foundry ceramic molds. The technique is based on the study of the optical density of solutions of pure components and their mixtures depending on the wavelength of transmitted radiation, available for a conventional laboratory photocolorimeter. The determination of the concentrations of organic components is based on a cyclic iterative calculation procedure based on a series of approximating equations describing the concentrations of components in a limited concentration range characteristic of a given binder.
