Abstract

Forming a harmonious color environment is an important aspect in creating comfortable living conditions in northern cities. Currently, there is a problem of using bark waste in woodworking and rubble waste during its processing. Thus, the use of these materials, including the creation of coatings and the formation of certain colors of city buildings, is relevant. This article presents a study of the color characteristics of dry blends and composites based on environmentally friendly raw materials. The purpose of the paper is to identify patterns of changing of color characteristics by varying the composition of wood and mineral mixtures and composites based on them. In the study we used the bark from the dump of a timber processing plant. The sifting of the basalt crushing from the Myandukha deposit was used as a mineral modifying component. Dry wood-mineral compositions were obtained by mixing wood and mineral fine powders. The study revealed a darkening of the wood-mineral composite in the process of structure formation and curing. In addition, there was a shift of chromatic color characteristics towards the original finely dispersed basalt. The obtained functional dependences of the color coordinates on the composition make it possible to determine the percentage of components in the finished composite and its strength by a non-destructive method. The results of the color characteristics study of dry blends and wood-mineral composites can be the basis for obtaining blends with desired color properties in the innovative coatings production. This, in turn, will allow to form and adjust the city color environment.
