Аннотация: The paper studies the effect of violation of the spreading of powder paints when they are compounded with nanofibers of aluminum oxide. It is shown that with the addition of small fractions of aluminum oxide nanofibers equal to 0.05 wt%, the grains of the powder paint do not have time to wet each other, the crosslinking of the coatПоказать полностьюing structure occurs up to this point, which is fixed by a characteristic granular texture. The paper also illustrates the features of the distribution of nanofibers of aluminum oxide in the coating. The increase in cohesion energy leads to a natural increase in the surface tension in the paint, which we observe in the form of the characteristic morphology of the coating. Investigation of coatings of a reference powder paint and a modified addition of aluminum oxide nanofibers) were carried out using an optical microscope. Separately, the morphology of the resin was investigated by scanning electron microscopy. Increasing the proportion of the flow agent based on acrylic compounds in the polyester resin from 0.8 to 1.8 wt% solves this problem, while the strengthening effect of nanofibers of alumina in the paint is retained. © 2021 Institute of Physics Publishing.
