PRODUCT SPARE PARTS - Polyethylene Ship Nose Assembly – 2 pcs - Polyethylene Ship Panel – 4 pcs - Ship Panel Metal Bolts – 8 pcs POLYETHYLENE PRODUCTS Low‑density linear polyethylene (LLDPE – Linear Low Density Polyethylene) is a thermoplastic used in a variety of applications. It is a semi‑permeable, easily moldable, and highly durable polymer that is favored in industry for its low cost and high resistance. Polyethylene grades are classified according to density and chemical properties. Its mechanical characteristics depend on molecular weight, crystal structure, and branching type. While properties vary by grade, the material generally offers good resistance to outdoor conditions and moisture, flexibility, low mechanical strength, and excellent chemical resistance. Polyethylene components are used to manufacture slides, stairs, railings, barriers, accessories, roofs, etc. To prevent colour fade, masterbatch dyes used for colouring polyethylene must have a light fastness rating of 6 or higher. The material thickness must be at least 6 mm (0.2 in) in areas exposed to pressure and friction, and a minimum of 4 mm (0.2 in) for barriers and shade structures that are not pressure‑loaded. The material should be evenly distributed to achieve uniform thickness. Dimensional tolerance for part thickness and measurements is ±5 %. CARRIER CONSTRUCTION The carrier structure will be fabricated from cold‑formed steel tubes with a minimum outer diameter of 114 mm (4.5 in) and a minimum wall thickness of 2 mm (0.1 in), complying with TS EN 10219‑2, TS‑6476, and DIN 2394 standards. Tubes will be welded using high‑frequency welding within the specified tolerance, dimensional, and cross‑section ranges. After sandblasting, the tubes will be coated with a polyester‑based electrostatic powder paint applied in a furnace. ELECTROSTATIC POWDER COATING All metal components will be sandblasted to remove oils, dirt, and rust, creating a porous surface that improves paint adhesion. A fine‑ball material inside a pressure‑resistant cabinet will be sprayed with compressed air to open additional pores and remove contaminants from the metal surface. After fabrication, each metal part will be coated with polyester‑based electrostatic powder and baked at 200‑220 °C for 20 minutes. Following this, parts will undergo a 10‑minute dip in a 70 °C, 5 % concentration degreasing bath, then a 15‑minute dip in a 50 °C, 1 % concentration iron bath. After thorough rinsing and drying, the components will receive a final polyester‑based powder coat and be cured in a 180‑200 °C oven for 20‑30 minutes. Weld seams will be fully painted after welding to prevent corrosion.
