Quick Answer
Tarred bankline exhibits superior abrasion resistance, significantly outperforming its untreated counterpart, due to the protective coating of tar which shields the cordage from friction and wear.
Tar Composition and Coating Process
Tarred bankline is created by applying a layer of tar to the cordage, typically using a hand or machine-based application process. A common tar-to-cordage ratio is 1:10, with 10% tar coverage by weight. The tar composition is usually a mix of pine tar, bitumen, and other additives, which provides excellent water resistance, adhesion, and durability.
Abrasion Resistance Testing
Abrasion resistance testing has shown that tarred bankline can withstand up to 300% more wear and tear than untreated bankline, with some tests revealing up to 400% improvement in abrasion resistance. This is due to the protective barrier of tar, which prevents the cordage from coming into direct contact with the surface it’s rubbing against. As a result, tarred bankline remains intact and functional for longer periods, even in harsh environments.
Practical Applications and Maintenance
In practical terms, tarred bankline is ideal for applications where cordage is exposed to heavy wear and tear, such as in mooring systems, towing lines, and other marine hardware. To maintain the tarred bankline’s performance, it’s essential to inspect and reapply tar as needed, typically every 6-12 months, depending on usage and environmental conditions. Regular inspection and maintenance can help extend the lifespan of the tarred bankline and ensure optimal performance.
