Abstract

Problem Statement (Relevance). Most often, the production of paints and varnishes consists of the main stages: from receipt to warehouses to packaging in boxes. And quality control is carried out at the entrance and at the exit. However, in the production of paints and varnishes, it is necessary to introduce intermediate control at the stage of grinding pigment raw materials into finely ground powder, since the main qualities of the finished paintwork product depend on the size range of particles of the finely ground powder. GOST 2093-82 recommends the use of sieve analysis, which is a sieving mechanism with a sieve from the largest mesh sizes to the smallest. However, this method is inferior to more modern ones in terms of analysis speed by more than 10 minutes, in terms of particle measurement range by 10-30%, and in terms of information content of the analysis. Objectives. Improving the quality of paints and varnishes through the introduction of intermediate control by laser diffraction. Methods Applied. In the presented work, methods such as mathematical modeling, the method of idealization and formalization of the research processes of paints and varnishes were applied. Originality. In the course of the work, new mechanisms were developed for assessing and controlling the quality of the particles of the coloring pigment powder, as well as new ways to improve the efficiency of the production of paints and varnishes. In the course of the study, an analysis of the technological process was carried out. Result. The result of the work was the developed model for improving the quality control system for the particles of the coloring pigment powder. Practical Relevance. The developed model will increase the effectiveness of current processes for the production of paints and varnishes through the introduction of intermediate control, which will increase the profit of the organization and reduce quality costs.
