Abstract

For successful recycling of polymericfluorine wastes by selecting equipment and its operating modes, their grinding to certain sizes of fractions, effective activation of the composite ingredients and their homogeneous combination is ensured. It is found that introducing fine aggregate, made of recycled materials, to polytetrafluoroethylene leads to the crystallization processes intensification that is associated with a decrease in the nucleation energy barrier. An increase in the content of the aggregate is accompanied by a decrease in the thermodynamic parameters of polymer composite materials and high strength and durability levels.

Critical concentration of aggregate, made of recycled materials, which ensure the composite structure homogeneity and the required performance characteristics, is defined. Critical concentration of aggregate, made of recycled materials is 25 %, thus, tensile strength of the composite σt= 20 MPa, compressive strength σc = 25 MPa, specific elongation δ = 140 %, wear rate I = 11,0∙10-6 mm3/N∙m are obtained. The methods of instrumental study have confirmed the efficiency of technology for obtaining polytetrafluorethylene composite with aggregate, made of polymericfluorine materials. Performance characteristics of the composite ensure increasing the service life of the seal assembly of compressor 4HM16-10/200 by 1.5 times.
