Abstract

Розроблено технологічні схеми формування епоксикомпозитних захисних покриттів з комбінованим наповненням мінеральними волокнами та дисперсними наповнювачами на робочі поверхні технологічного обладнання. Схеми побудовано на основі досліджень умов формування структур композитних матеріалів у зонах міжфазних взаємодій біля поверхні наповнювача.

The development of polymer composite materials (CM) for components of the process equipment is based on the study of physical and chemical processes in the system, "the matrix-filler." In the solid state epoxy polymers possess complex of valuable technical properties: cohesive and adhesive strength, chemical resistance and dielectric performance. Modification of filler followed by UVR compositions provides increased speed of matrix stitching and significant increase in the degree of gel formation fraction with aluminum oxide and basalt fibers contain as compared with other studied materials. Based on the performed studies, methods and ways of improvement of the wear resistance of the material were developed. A new polymer СM and coatings based on them to protect equipment from the surfaces of complex profile, as well as technologies for their formation were created. Increased performance of the developed coatings demonstrates their high efficiency and the need to broaden their production. The method of forming epoxy composite coatings and technological scheme of composite material with fiberfill and protective coatings manufacturing equipment is proposed in the paper. Flowsheet consists of 4 stations. Each station is connected respectively with each other in order to improve the quality of CM. Setting for external protective coating can be carried out in a mobile version. Control of chemical and physical interaction mechanisms at the interface provides the ability to adjust the parameters of the structure of the matrix and as a result – their performance. That is why presented development of the technology combining the components in the composite for their implementation in the industrial production is of great importance as well the need to broaden implementation in enterprises of different industries in Ukraine.
