DEVELOPMENT OF AN IMPROVED METHOD OF COMPLEX EXPRESS QUALITY CONTROL OF VARNISHES AND PAINTS

Abstract

This article analyzed the main characteristics of different types of paints. Defined requirements for paint property depending on conditions and methods of use. Established the property list of paint and varnish materials that determine its quality. Defined dependence to property of paints from the type of shape, structure and porosity of the surfaces that they are applied on. The existing methods of control of individual properties of paints and varnishes are analyzed. The need to develop a comprehensive method of express quality control of paint and varnish material to ensure its quality control in the specific conditions of its application to a certain surface under the given conditions of use was substantiated. Based on a simulation of the process of wetting a certain surface with a paint and varnish material, it was established that with the help of this method, it is possible to control the quality of the paint and determine the conditions of its use. Substantiated that it is advisable to control the speed of the process of wetting a specific surface with paint in an automated mode based on an optical method, which makes it possible to perform express control of paint and varnish material in a dynamic visual mode.
