PATH OF LIFE
He was born in 1936 in the Poltava region. In 1961 he graduated from the Faculty of Road Construction of the Kyiv Automobile and Road Institute. After graduation he worked at the design institute as an engineer.
From 1962 he worked at our institute as an Engineer, Junior Researcher, Researcher and Head of Department. In 1967 he defended his thesis and received the title of PhD.
WORKING PATH
From 1969 to 1997 he was the Head of the Department of Organic Binders. The scientific activity of the department under his leadership was aimed at improving the properties of traditional organic binders (bitumen, tar) and the development of new types of binders.
Under his leadership, the institute developed and implemented a fundamentally new technology for producing bitumen emulsions by chemical emulsification. A new method of emulsification is a special kind of processes of self (spontaneous) emulsification, associated with the chemical reactions at the interface of bitumen - an aqueous solution of alkali or acid. A distinctive feature of this technology is the formation of an emulsifier in situ (in the system itself), which allowed by such chemical reaction of small formation, grinding bitumen into drops of about 1 μm. In order to make full use of the chemical activity of the reaction, it is necessary to create optimal conditions for its occurrence.
It is these conditions Kuchma M.I. was able to develop by specially designed and very simple device, which was introduced into further production. In almost all regions of Ukraine there were installations for the production of bitumen emulsions which were used to perform various types of work in the construction and repair of road pavement. In terms of their use, Ukrainian road workers occupied leading positions in the former Soviet Union. To implement the method of chemical emulsification of bitumen, special cationic emulsifiers, which were synthesized in the department and called carboxylamines were required. Carboxylamines could also be used as effective adhesive additives to improve the adhesion of bitumen to stone material.
SCIENTIFIC INTERESTS
Scientific development, which is directly involved Kuchma M.I. became a technology for the production of surfactants of the cationic type, which at one time significantly affected the technical progress in the road sector, and later received a new impetus in the development and production of domestic emulsifier “Desetam” and adhesive additive UDOM-1 and UDOM-2, the release of which allowed abandoning much more expensive imported.
