Uhmwpe wear strips

Types of UHMWPE Wear Strips

UHMWPE wear strips are manufactured in various types. Each type use varies depending on the industry and application required. Below is a list of some popular ones.

Static Wear Strips

These wear strips are designated for fixed applications where there is no movement. Such applications include conveyor beds or guide rails. Their durable nature and high abrasion resistance make them ideal for protecting surfaces from wear. The users mainly use static strips to extend the life of equipment in low-load environments.

Roller Wear Strips

This type of strip is commonly used in conveyor systems. Roller wear strips are designed to accommodate rollers and reduce friction. Hence, they provide smooth operation. Their lightweight and impact-resistant properties enhance the overall efficiency of material handling systems.

Dynamic Wear Strips

As the name suggests, people use these types of strips in dynamic applications involving constant movement. Common examples include sliding surfaces in machinery and conveying systems. Users choose to Dynamic Wear Strips because of their exceptional resistance to fatigue and wear. Therefore, they are ideal for high-traffic areas where consistent motion occurs.

Wear Strip Chains

Adding a wear strip to a chain provides a solution to protect it from excessive wear while also improving its longevity. This type of wear strip is commonly used in bucket elevators, conveyors, and other types of machinery that have chains. Usually, they come from durable UHMWPE materials. Thus, they help minimize friction between the chain and the surface it contacts.

Crawler Wear Strips

Wear strips are critical components for extending the life and reducing the impact of Crawler and other heavy machinery. Often, users install Crawler on concrete floors. therefore, having a durable anti-scratch coating for concrete is essential. These strips not only reduce wear on the machine but also provide a smoother ride over various terrains.

How to Use and Install UHMWPE Wear Strips

Using UHMWPE Wear Strips

Wear strips have multiple applications throughout industrial settings. Usually, due to their unique properties, users favor them for heavy-duty, high-wear environments.

• Conveyor Systems: In most cases, wear strips are installed in conveyor systems to reduce friction. Moreover, they enhance the smooth operation of materials being transported. Ontop of that, their low friction surface minimizes wear on conveyor components. This extends the life of the systems.
• Guides and Tracks: Users install wear strips along guides and tracks in various machinery. This is to create a smooth sliding surface for moving parts. UHMWPE's ability to withstand heavy loads and resist abrasion makes it ideal for high-traffic areas.
• Bucket Elevators: Often, bucket elevators integrate wear strips into their design. This protects compartments and buckets from excessive wear. Usually, the strips reduce friction during the movement of materials. This makes it easier for the elevator to transport bulk goods.
• Automated Systems: Users also apply wear strips in robotic and automated systems to ensure precise movements. These strips act as buffers between components. They prevent metal-on-metal contact, which can lead to wear and tear.
• Trolleys and Carts: In addition, trolleys and carts benefit from UHMWPE wear strips. This helps to minimize wear on wheels and tracks. Commonly, these strips provide a durable surface that absorbs shocks. Hence, they are ideal for reducing impact in sensitive environments.
• Rail and Piping Systems: People also use wear strips in rail and piping systems. The strips serve as a protective barrier against corrosion and abrasion. Thus, prolonging the lifespan of essential components.

Installation of UHMWPE Wear Strips

Normally, installing a UHMWPE wear strip is a straightforward process. Here is some basic guidance for a successful installation:

• Surface Preparation: The installation surface should be thoroughly cleaned. Check for any debris, dirt, or old materials that may hinder the strip from having a good surface contact.
• Cutting the Strip: The wear strip needs to be cut into the desired size. This should be done prior to the installation. Use a fine-toothed saw or a bandsaw. Avoid using power tools that generate heat. This is because excessive heat will degrade the UHMWPE material.
• Application of Adhesive: Depending on the requirements, the use of adhesive will be necessary. Normally, a strong epoxy or construction adhesive is recommended. Apply a thin, even layer on the back of the wear strip. Also, a corresponding layer on the surface where the strip will seat.
• Pressing the Strip: Position the wear strip into place and firmly press it down. Make sure the strip has even contact with the surface. This ensures maximum adhesion.
• Use of Fasteners: For added security, fasteners such as screws or bolts should be used. This is especially important in high-wear areas where additional mechanical fixing may be required.
• Curing Time: Allow sufficient time for the adhesive to cure. Follow the manufacturer's instructions for guidelines on curing time.

Benefits and Disadvantages of UHMWPE Wear Strips

Benefits of UHMWPE Wear Strips

• High Abrasion Resistance: Normally, UHMWPE wear strips have an exceptional ability to withstand abrasion. Thus, making them ideal for harsh environments. The general use of wear strips is to extend the life of machinery and equipment.
• Low Coefficient of Friction: Usually, these wear strips have a low coefficient of friction. Therefore, they provide smooth operation with minimal resistance. This feature helps to enhance efficiency in systems where sliding or movement occurs.
• Shock Absorption: In addition, the wear strips offer superior shock-absorbing properties. They reduce the impact on equipment. Therefore, leading to less wear and tear over time.
• Lightweight: The materials used in manufacturing UHMWPE wear strips are relatively lightweight. Although not as strong as metals, the strips are easier to handle and install without requiring heavy-duty equipment.
• Chemical and Moisture Resistance: They possess the ability to withstand various chemicals, oils, and moisture. Hence, making them suitable for use in outdoor and industrial settings.

Disadvantages of UHMWPE Wear Strips

• Limited Temperature Range: At extreme temperatures, the wear strips start to lose their effectiveness. Although they are resistant to heat, they can only manage up to 80°C.
• Surface Scoring: In high-load applications, their low friction surface can sometimes score adjacent metal surfaces. This leads to unwanted wear on nearby components. While reducing friction is generally advantageous, it may lead to surface damage when not properly managed.

This is because the material cannot form a protective layer, which in most cases prevents the metal from contacting UHMWPE.

• UV Degradation: Long-term exposure to direct sunlight ideally causes degradation of the strip material. Sadly, the wear strips become brittle and lose their properties. Although UHMWPE has UV resistance, it degrades with time. So, it is not suitable for long-term outdoor applications without protection.
• Cost Considerations: When compared to alternative materials, the initial cost of purchasing UHMWPE wear strips is relatively high. This makes them less favorable for industries on a tight budget.
