In the course of this work the reduction of emissions of free formaldehyde from the finished plywood is identified, as well as an increase in shear strength to the adhesive layer. Obtained effects in the manufacture of plywood are due to the use of adhesive compositions using natural zeolite sorbent filler – clinoptilolite, previously activated in various electromagnetic fields (fields of over high frequency and weak pulsed magnetic fields). The optimal processing modes of minerals with electromagnetic fields are defined, providing an optimum ratio of values ​​of free formaldehyde emission levels and shear strength to the adhesive layer. The results indicate the possibility of industrial use of the developed techniques.

Change of nature and ratios of the active centers had been carried out, by the test reaction of conversion of methylbutanol (МВОН), was defined resizing of particles and stability of zeo-lite by dynamic light scattering (DLS), changing of level of wastewater treatment from formal-dehyde and heavy metals depending on the method of activation clinoptilolite are shown in paper
