Application advantages of UHMWPE sheets as wear-resistant liners:‌

‌Role of coal bunker liners:‌ In the mining industry, UHMWPE is used as the sliding surface for chutes and hoppers, leveraging its excellent wear resistance and chemical resistance. It addresses practical challenges such as material adhesion, difficulty in conveying raw materials, and poor wear resistance in coal mines and coal washing plants.

‌Examples:‌ The new generation of self-discharging ore carriers, railway wagons, and large trucks may use UHMWPE due to its smooth surface, non-stick properties, and wear resistance. These characteristics also make it suitable for agricultural and earthmoving machinery, where UHMWPE is used to protect steel. When cargo compartments are loaded with sand or clay for extended periods, UHMWPE sheets provide excellent wear resistance and non-stick properties.

Ultra-high molecular weight polyethylene (UHMWPE) is a high-molecular-weight polymer known for its exceptional wear resistance, self-lubricating properties, high strength, chemical stability, and strong anti-aging capabilities. When identifying genuine UHMWPE sheets, it is essential to focus on these characteristics.

 

Here are specific identification methods:

• Weight Measurement Method‌:

Genuine UHMWPE products have a specific gravity between 0.93 and 0.96, making them less dense than water and able to float. If the material is not pure polyethylene, it will sink.

 

‌• Temperature Test‌:

Pure UHMWPE does not melt or deform at 200°C but will soften. Non-pure polyethylene materials may deform at this temperature.

 

‌• Visual Inspection‌:

Genuine UHMWPE has a smooth, uniform, and glossy surface with a very even cross-section density. Non-pure materials may appear dull and uneven.

 

‌• Edge Test‌:

The edges of genuine UHMWPE are rounded, uniform, and smooth. Non-pure materials may have cracks, and the edges may chip when heated during processing.

Ultra-high molecular weight polyethylene (UHMWPE) wear-resistant liners are widely used in industries such as mining, coal washing plants, metallurgy, thermal power plants, and shipbuilding. They are applied in chutes, hoppers, flip plates, scraper conveyor slides, jig screens, flotation cell liners, ship cargo hold liners, large sliders, mine cars, and dump truck liners for wear and corrosion resistance, offering exceptional value.

 

Detailed step to install the liner as below : ‌

• Special Countersunk Steel Bolts with Locking (Anti-Loose) Nuts‌:

These bolts are designed to secure the liner in place while preventing loosening.

 

‌• Impact Screws with Washers‌:

Threaded screws are driven into the steel plate, eliminating the need for nuts. This method requires extensive drilling, increasing labor and tool wear costs.

 

‌• Stud Welding for Convenience‌:

1. Threaded studs are welded onto the steel plates of storage bins and chutes. To ensure weld quality and protect the plastic liner from high temperatures during welding, ceramic ring-protected arc welding is used. This method concentrates the arc, allows the workpiece to cool slowly, and creates neat, standard welds.

2. Due to the liner's thermal expansion coefficient of 2×10⁻⁴/°C, the fixing method must accommodate free expansion or contraction when operational or environmental temperatures vary significantly.

(UHMWPE) profiles are increasingly used in modern industrial production due to their exceptional properties, including high wear resistance, low friction coefficient, impact resistance, self-lubrication, low-temperature resistance, non-toxicity, non-stickiness, water resistance, and low density. This material is often referred to as the "wonder plastic."

UHMWPE profile products include pulleys, bushings, bearings, rollers, chains, guides, gaskets, and blocks, and can also be custom-made to meet specific requirements.

Yes, phenolic composite board is internationally recognized as one of the most promising new insulation materials in the construction industry. Unlike conventional polymer resins that rely on flame retardants, this new material is fundamentally different—it does not burn, melt, or release toxic smoke when exposed to fire. It is also lightweight, non-corrosive, energy-efficient, soundproof, and cost-effective. Additionally, it does not use Freon foaming, making it environmentally friendly, easy to process, and convenient to install. Its comprehensive performance is unmatched by other insulation materials.

In developed countries, phenolic composite boards have developed rapidly and are widely used in construction, foreign trade, storage, and energy sectors. In the U.S., phenolic materials account for 40% of the soundproofing and insulation foam plastics used in the construction industry. Japan has also established a phenolic foam promotion association to promote this new material.
