Linerkerroksen

Linerkerroksen is the Finnish term used to describe a liner layer—a thin interior layer applied to the inside surface of a vessel, pipe, container, or structure to provide barrier, protective, or functional properties. As an interior lining, its primary role is to separate the substrate from another medium (such as chemicals, moisture, or the atmosphere) and to improve surface performance without bearing structural loads.

Materials used for linerkerroksen vary by application and may include polymers such as high-density polyethylene (HDPE), fluoropolymers (PTFE, FEP), elastomers, ceramics, metals, or composite laminates. The choice depends on chemical compatibility, temperature range, mechanical wear, and the required barrier properties. Typical thicknesses range from a few micrometers in electronics or food-contact equipment to several millimeters in chemical plants or waste containment.

Common applications span chemical processing equipment, storage tanks, pipelines, heat exchangers, electrical equipment, medical devices, and landfill or groundwater containment systems. In civil and environmental engineering, liner layers are employed as corrosion or chemical barriers, often in combination with adjacent substrates like metal walls or concrete and with dedicated sealing or bonding methods.

Installation considerations include surface preparation, adhesion or bonding method, thermal expansion, and long-term durability under service conditions. Potential challenges are delamination, wear, chemical attack, or incompatibility with substrates or contents.

Linerkerroksen relates to coatings, protective linings, and barrier technologies. Related topics include geomembranes, corrosion protection, insulation, and composite laminates.
