Abstract

Statement of the problem. The task of studying shungite to create effective radio-absorbing materials in construction production is considered. The need for this is dictated by a high density of electromagnetic fields in places of finding or resolving a person and a negative influence on his health. Results. The influence of the composition of building mixtures based on shungite of the Zazhogihinsky membrane is investigated by the absorption of microwave energy in a wide frequency range. The use of the measuring unit based on a scalar chain analyzer and measuring paths in the form of a microwave resonator, made it possible to measure the absorption values of the electromagnetic energy in a wide range of frequencies. The increase in the absorption of shungite is shown in increasing its concentration in the samples under study with values up to 24 dB/cm. Conclusions. The effectiveness of the use of shungitis is proved as a filler of building mixtures or with binders (plaster, phosphogypsum) to form protective coatings of walls or wall materials from the effects of electromagnetic energy per person. The most optimal ratio is 50-60 percent of shungite and the rest of the knit, while the frequency range of the absorption is 3-12 GHz.

Influence of Kazakhstan’s Shungites on the Physical–Mechanical Properties of Nitrile Butadiene Rubber Composites

Shungite ore and concentrate can partially replace carbon black in nitrile butadiene rubber composites, improving tensile strength and reducing Mooney viscosity without significantly affecting resistance to oil-based media.
