32 Intumescent coatings for fire protection of lithium-ion batteries — Candidate of Military Sci. Savelyev D. V., Doctor of Tech. Sci. Drinberg A. S., Candidate of Chem. Sci. Pavlovich A. V., Doctor of Tech. Sci. Zybina O. A.
Abstract.
The combustion mechanism of lithium-ion batteries (LIB) has been studied. Research on the development of fire-intumescent coatings to protect LIB from fire is reviewed. Еstablished that the most effective means of fighting fire in LIA is the combination of fireproofing agents with non-flammable ballistic fabrics has been. revealed that to create an ORP to protect LIBs, paint and varnish compositions based on intercalated graphite and vinyl alkyds should be used has been.
Keywords: lithium-ion battery (LIB), intumescent coatings, thermal runaway, ballistic fabric, foam coke, jet fire, intercalated graphite, vinyl alkyd.

17 Silver — for electronics, electrical engineers, jewelers, but not to the coatings producers — Candidate of Tech. Sci., Associate Professor, Voitovich V. A., Candidate of Tech. Sci., Prof. Khryapchenkova I. N.
Abstract.
The article argues that silver, as a biocide, cannot be used to protect water-based coatings from biological damage, because being in nature, their waste will disrupt the microbiological balance in natural ecosystems. More environmentally friendly biocides have been proposed to protect water-based paints from bio-contamination.
Keywords: silver, biocides, bioimages, quaternary ammonium compounds, polyvinyl acetate dispersion.

22 Activity of mono- and dizirconyl carboxylates in the presence of cobalt and manganese dryers in the curing of alkyd binders — Sotnikov A.V., Candidate of Chem. Sci. Stoyanov V.M., Doctor of Tech. Sci. Prof. Savostyanov A.P.
Abstract.
The activity of zirconyl and dizirconyl carboxylates as dryers in combination with cobalt and manganese in the most common types of alkyd binders – fatty alkyd varnish, alkyd-urethane and alkyd-styrene lacquers, was studied.
In this purpose, 2-ethylhexanoates of zirconyl and dizirconyl were put in various ratios with primary dryers (2-ethylhexanoates of cobalt and manganese) into varnishes and applied to a glass substrate. Then the drying time and the rate of hardness gain of the obtained films were measured.
It was found out that for all types of binders, the activity of zirconium dryer depends only on the amount of metal introduced into the varnish and, in the case of using 2-ethylhexanoates of zirconyl and dizirconyl, does not depend on the type of zirconium compound used. The optimal molar ratios of cobalt with zirconium (1:2) and manganese with zirconium (1:1) have also been identified, which allow to obtain the maximum drying rate and a set of hardness of alkyd binders.
Keywords: dryers, carboxylates of zirconyl and dicirconyl, 2-ethylhexanoate of cobalt.

TECHNOLOGIES AND EQUIPMENT
37 Design management and operation of the lines for the production and application of powder paints — Candidate of Tech. Sci., Associate Professor Boldyrev V. S., Doctor of Tech. Sci., Prof. Menshikov V. V., Tishkin V. V., Candidate of Tech. Sci., Associate Prof. Nevmjatullina H. A., Zubarev A. M., Volodin D. V.
Abstract.
The article discusses the possibilities of using innovative methods for the design and development of powder paint production lines. The problem of choosing software for searching and identifying problem areas of the line for subsequent effective solution of the found shortcomings has been solved. The features of the production of epoxy powder paints and the development of production lines for the paint and varnish industry were studied. Using the AutoCAD software environment, a project was created to modify and reengineer a section of the production line for producing and applying powder paints.
Keywords: paint technologies, chemical-technological system, production organization, computer-aided design, epoxy paints, powder coatings, production lines, engineering.
