Some surface reactions which occur between modified under the action of small doses (D) of penetrating radiation on aerosil with polyamide and epoxy resins have been studied. Experimental data on the basis of the reconstruction of surface hydratehydroxylic cover have been discussed. It has been shown that adhesive properties of glues prepared using aerosil-type modified fillers depend on the conditions of preliminary treating of blends. The diffractographic analysis of unmodified and modified with γ-radiation (D = 100 Gy) silicon samples shows that under the action of radiation, phase transition occurs on SiO2 crystoballite and tridimite phases are formed.

Abstract


Some surface reactions which occur between modified under the action of small doses (D) of penetrating radiation on aerosil with polyamide and epoxy resins have been studied. Experimental data on the basis of the reconstruction of surface hydratehydroxylic cover have been discussed. It has been shown that adhesive properties of glues prepared using aerosil-type modified fillers depend on the conditions of preliminary treating of blends. The diffractographic analysis of unmodified and modified with γ-radiation (D = 100 Gy) silicon samples shows that under the action of radiation, phase transition occurs on SiO2 crystoballite and tridimite phases are formed.
