Epoxy resin is a kind of polymer material with high performance. It is a two-component system composed of epoxy group and amine group, which forms polymer compound by mixing and reaction. It has strong adhesive force, corrosion resistance, heat resistance, electrical insulation and mechanical strength, and is widely used in aviation, aerospace, automotive, construction, electronics, ships and other fields.

The preparation process of epoxy resin is to mix epoxy resin monomer and amine Curing Agent in a certain proportion, and react at a certain temperature to form a polymer compound. Epoxy resins with different properties can be obtained by changing the type of monomer, the type and proportion of curing agent.
The advantage of epoxy resin is that its properties can be adjusted according to needs, and materials with high strength, high stiffness, high toughness, high temperature resistance, corrosion resistance and other characteristics can be prepared. Because of its excellent properties, epoxy resins are widely used in various fields. For example, in the aerospace field, epoxy resins are used in the manufacture of aircraft and rocket structural parts, composites, coatings and adhesives; In the automotive field, epoxy resins are used in the production of automobile body and engine parts; In the field of construction, epoxy resins are used in coatings, floors, waterproof materials and so on.
In addition, carbon fiber reinforced epoxy resin composites are also one of the most widely used epoxy resin products at present. Carbon fiber reinforced epoxy resin composites have the advantages of high strength, high modulus and low density, and are widely used in aviation, aerospace, automobile, sporting goods and other fields.
In general, epoxy resin is a high-performance material with a wide range of application prospects, and its properties can be adjusted according to needs, and it is widely used in various fields.
It is reported that Rolls-Royce plans to supply the LNG propulsion system to a cargo ship being built at the Tersan shipyard in Turkey, designed by NSK Marine Design Company for the Norwegian shipowner NSK.
The newly built ship is slightly larger than the sister ship MS Høydal, which was also built by Tersan shipyard in 2012. At the time, the "MS Høydal" was the world's first LNG-powered freighter.
With a total length of 81.5 meters, the vessel can deliver 2,700 tons of fish food for the BioMar Group's multiple fisheries on the Norwegian coast.
Dristian Høydal, Managing Director of NSK Shipping, said: "We are very proud to once again win the trust of the BioMar Group to deliver relevant feed products to the fish farming industry and to work closely with Rolls-Royce to provide environmentally friendly and efficient The LNG powered ship."
Helge Gjerde, President of Marine and Merchant Marine Systems Solutions, said: "The modern technology jointly invested by BioMar Group and NSK Shipping Company can effectively reduce fuel costs and reduce environmental impact. Both parties are leading in offshore shipping."
It is understood that the entire LNG propulsion system includes an 8-cylinder Bergen C26:33 gas engine with a power of 2160 kW; a Promas integrated paddle rudder system; a side thruster and a side thruster; and a set of Rolle Royce Automation and Dynamic Positioning System.
In addition, the ship is equipped with a Rolls-Royce hybrid shaft generator (HSG) propulsion system. This means that the ship's main engine can also generate electricity for the entire ship at different speeds, thus effectively reducing fuel consumption. Moreover, the shaft generator can also be operated as a propulsion motor (PTI condition), so that the diesel auxiliary machine can also carry out the whole ship propulsion when the ship is in operation.
The Bergen B and C-Series gas engines emit 22% less CO2 than conventional diesel engines (including methane emissions), 90% reduction in NOx emissions, and virtually eliminate sulfur oxide emissions. The LNG system can effectively reduce maintenance costs while providing a more comfortable working environment for the crew.
According to the plan, the ship will be completed and delivered in 2017.
