Why Does the Service Life of Traction Tread Planks Decrease?

Why does the service life of traction tread planks decrease?

As people’s living standards continue to rise, there is an increasing demand for the establishment of surrounding public facilities. Traction tread planks, as essential construction materials, are used in a growing number of applications due to their strength. With the increasing demand, customers are becoming more meticulous in their purchases, hoping that the traction tread planks they acquire are durable and reliable.

The longer the service life of traction tread planks, the lower the cost for customers. Therefore, it is essential for customers to have sufficient knowledge of traction tread planks.

Firstly, in the selection of materials for traction tread planks, it is crucial to strictly follow the design’s load-bearing requirements. Cutting corners in materials, such as using 3.5mm thick flat steel instead of the required 4mm, can lead to deformation, bending, and even fracture of traction tread planks under prolonged overload conditions. This could result in increased costs instead of cost savings.

Additionally, the surface treatment and the operating environment of traction tread planks are factors affecting their service life. Surface treatments typically include hot-dip galvanizing, cold galvanizing, and painting. Traction tread planks treated with hot-dip galvanizing exhibit excellent resistance to acid and alkali corrosion. The zinc layer forms a stable protective film on the surface, and with a zinc layer thickness of 100μm, the product’s lifespan varies in different environments: up to 30 years in dry outdoor conditions, around 25 years in normal outdoor conditions, 15 years in coastal areas, and 10 years in typical industrial areas. Even in harsh marine environments, the lifespan is between 5-8 years, and the product can endure 3 years in extremely adverse conditions. Traction tread planks treated with cold galvanizing have weaker corrosion resistance, lasting around 2 years in dry conditions and only about 6 months in wet conditions. The lifespan of painted traction tread planks is typically around 1 year.

Traction tread planks are susceptible to corrosion from impurities in the atmosphere.

As circulating cooling water evaporates and concentrates, the salt concentration increases, leading to deposition and scaling.

Additives in the cooling water treatment process can produce precipitates.

Various impurities in the atmosphere, such as dust and suspended solids, as well as leaks and peeling of cooling tower fan oil, can enter the water.

The loss of CO₂ during the spraying process in the cooling tower exacerbates the precipitation of CaCO₂ in the water. Meanwhile, the increase in O2 content in the water enhances its corrosiveness.

Microbial growth and secretions in the system form sticky deposits.

To extend the service life of traction tread planks, attention must be paid to cleaning and protection. Traction tread planks have excellent corrosion resistance due to the dense passivation protective film on their surface. This film, a stable oxide layer, can exist in a highly stable state in the natural environment, resulting in a longer lifespan and appealing aesthetics. Therefore, to ensure the decorative and durable properties of traction tread planks, cleaning and maintenance are indispensable.

Cleaning and maintenance methods for traction tread planks

Cleaning with water is recommended to prevent the use of bleach and abrasive washing solutions, steel balls, or abrasive tools. Rinse the appearance with water after cleaning, taking care not to scratch the surface, as this could damage the protective film and affect the lifespan of traction tread planks.

For dust removal, use warm water for cleaning. For stubborn dirt, use mild cleaners or soapy water. For grease and difficult-to-clean dirt, use a soft cloth and then clean with a neutral detergent or ammonia solution. After cleaning, promptly remove any residual detergent from the surface with clean water.

If external rust removal with various acids is necessary, rinse with water immediately after rust removal. Then soak in an ammonia solution or neutral sodium carbonate solution and clean with a mild cleaner or warm water. After cleaning, apply rust-proof paint promptly to prevent rust stains from spreading.
