Advanced coating of Tank Interior as means of Rising Environmental Safety of Tankers/RIM technology
The application of Reaction Injection Molding (RIM) technique for forming an elastic polyurethane coating that displays selected strength characteristics, and chemical and thermal resistance is described. The study was conducted on technical-scale using a mixing dosing device that allowed direct dosing of liquid polyurethane system into the steel bulkhead, onto the steel surfaces, and the formation of polyurethane coating. Hard coating formed after polymer gelation and crosslinking. The elaborated technology also allowed joining of ceramsite concrete which resulted in the sandwich costruction consisting of steel, concrete and polyurethane.
