Optimization of Ingredients upon Development of the Protective Polymeric Composite Coatings for the River and Sea Transport

Abstract

It is proved that in order to increase the operational characteristics of parts of the river and sea transport, including their physical and mechanical properties, it is advisable to use the protective polymeric composite coatings.
 The effect of fillers on the flexural stresses of the developed epoxy composite was analyzed. The critical content of components was determined by the method of mathematical planning of the experiment: the synthesized powder mixture - 0.05 pts.wt., discrete fibers - 0.10 to 0.15 pts.wt. per 100 pts.wt. of epoxy oligomer ED-20. Introduction of such ingredients into the epoxy binder allows to increase the flexural stresses to σ f=77.4…78.6 MPa. The obtained results allow to create materials with improved values of physical and mechanical properties.

Epoxy Nanocomposites with Increased Hydroabrasive Wear Resistance for Use in Vehicles

“…Taking into account the results of previous studies [18][19][20][21], we tested and established indicators of wear intensity under the influence of hydroabrasive of the following materials:…”

Ecotoxicity Study of New Composite Materials Based on Epoxy Matrix DER-331 Filled with Biocides Used for Industrial Applications

“…Additionally, two fillers in the complex (nanosilver and oxytetracycline) were used to improve the properties of the protective coatings, the optimal content of which was determined by the method of the mathematical planning of the experiment using the STATGRAPHICS ® Centurion XVI application package. Orthogonal central compositional planning was used to optimize the content of fillers of different nature to form the protective coating [50,51]. The content of the main and additional fillers was selected based on complex studies of the physical and mechanical properties of CM.…”

“…According to the experimental design scheme, nine experiments were performed (N = 9), each of which was repeated three times (p = 3) to rule out system errors (Table 2). In order to obtain an orthogonal planning matrix [50][51][52], the corrected level values, x , were entered and calculated using (1).…”
