摘要: Economic and social development of both the country as a whole and its individual regions is impossible without maintaining the required level of development and technical condition of the road network. This also applies directly to agricultural producers. Despite the fact that considerable funds are allocated for the construction and repair of roads, the service life of roads often does not meet the standard values. One of the reasons for the low service life of road structures are design error

摘要: The working tool of machines with circular cutting units is a circular saw, the condition of which largely determines the quality of material processing. Circular saw blades in the process of operation are subjected to a complex effect of force and temperature factors that cause elongation and deformation of the saw blade, and the occurrence of internal stresses that take it out of the flat form of elastic balance and reduce the tool’s performance. The ability of saws to resist these factors is

摘要: At the moment, there is a wide variety of materials for air filtration, however, it is necessary to develop new, more efficient and cost-effective materials. Numerous studies have shown that in order to obtain a highly effective filter material for fine air purification from particles of 0.1–0.5 μm, ultrafine and microfine glass fibers should be introduced into the composition. Glass fibers have a whole complex of unique properties: thermal, chemical and biological resistance, high specific surf

摘要: A method for homogeneous nitration of kraft lignin (KL), which consists in its treatment with acetyl nitrate in 1,4-dioxane, tetrahydrofuran, or dimethyl sulfoxide, has been proposed. The effects of reaction time and consumption of acetyl nitrate on KL nitration were studied. A new absorption band with a maximum at 430 nm due to aromatic nitro groups appears in the ionization spectra upon KL nitration. The intensity of this absorption band rises with an increase in consumption of acetyl nitrate

摘要: The prohibition of drift floating used in the initial timber rafting led to an increase in the cost of supplying timber to consumers. Nowadays, the technology for rafting operations on small and medium-sized rivers is developing in two directions. The first is the use of bunches (micro-bundles) in initial timber rafting which, after rafting along the rivers with limiting rafting dimensions, are joined together to form, for example, a two-tiered bunch of rafting units. The second is the use of fl

摘要: The use of a mobile small-sized berth, the design of which was proposed by the authors in the previous paper, significantly increases capacity and reduces the cost of timber transshipment. When towing the berth over large distances, its ballast tanks are empty, which ensures that draft and water resistance to movement are minimized. At the point of operation the leveling ballast tank is filled with water until the top surface of the berth is leveled. In this position, the berth is moved locally

摘要: The lower curing temperature of phenol formaldehyde binder allows reducing the costs of producing cellulose-containing materials, such as FSF plywood and thermal insulation composites made of plant wastes. However, the low-temperature production mode provides an insufficient degree of the phenol formaldehyde binder curing, leading to a decrease in water resistance of material based on the phenol formaldehyde binder. A modifier should be added to the phenol formaldehyde binder to reduce the amoun

摘要: Wood drying (in particular lumber drying), which almost entirely determines the quality of the wooden products, is one of the most complicated and energy-consuming processes in wood processing. Convective drying of lumber, in all its varieties, remains the most common by far. Computer modeling of wood drying processes is usually based on solving systems of differential heat and mass transfer equations. The methods for solving such systems, both analytical and numerical, are well researched and d
