A recent trend has emerged in mines, power plants, and cement plants: the traditional steel linings are being replaced by plastic sheets (UHMWPE liner sheet ). This isn't simply a replacement of engineering plastics, but a revolution in advanced production technology driven by significant economic benefits! Today, we'll explore why it has become the preferred product for these heavy industrial sectors.
The key to choose UHMWPE liner sheet lies in three key factors: saving money, reducing time, and improving efficiency.
1. Excellent wear resistance extends its service life and saves material costs
This is the core reason. In conditions with extremely severe abrasive wear, such as in mine crushers and power plant coal chutes, manganese steel sheets can wear through in just 3-6 months, necessitating frequent replacement, which is time-consuming and costly. Therefore, construction sites urgently need more wear-resistant alternatives to manganese steel sheets. Our UHMWPE liners stand out for their exceptionally high wear resistance, boasting over 7 times the wear resistance of manganese steel. After replacing the coal bunker chutes at a power plant in Mexico, the lining life was extended from one year to eight years! Calculating the savings in material costs, labor costs, and downtime, this easily translates to hundreds of thousands of yuan per year.
2. Self-lubricating properties, completely saving time.
Traditional metal liners have a rough surface, making wet coal dust and sticky materials easily adhere to them, causing "sticking" and "arching," which can block the bunker opening and require frequent manual cleaning, which is both dangerous and disruptive to production. UHMWPE liners offer an extremely smooth surface with a very low coefficient of friction, comparable to a non-stick pan. Materials flow smoothly down the chute, eliminating clogging. This is ensuring continuous production and reducing worker workload.
3. Impact-resistant "soft armor" for increased safety and efficiency
UHMWPE offers exceptionally high impact strength and excellent toughness. When large pieces of ore or coal are dropped from a height, it effectively absorbs the energy of the impact through deformation, preventing cracking like ceramic liners or the clanging, noise, and deformation of metal. Like a "soft armor," it silently protects equipment, reduces unplanned downtime, and improves operational efficiency and worker safety.
It also offers several key advantages:
• Lightweight: Weighing only 1/8 of steel, it's particularly easy to install and transport.
• Corrosion-resistant: Resistant to water, weak acids, and weak bases, it offers greater adaptability to environmental conditions.
• Low noise: The noise level from impact is much lower than that of metal, improving the working environment.
UHMWPE liner sheets perfectly meet the ultimate goal of cost reduction and efficiency improvement for mines and power plants, which strive for continuous, stable, and efficient production and maintain strict cost control. Ultra-high molecular weight polyethylene liner sheets extend service life several times, prevent clogging, and reduce maintenance. These are the fundamental reasons why Tianjin Beyond Technology Development Co., Ltd.'s UHMWPE liner sheets have become a perfect alternative to steel liner sheets, rapidly gaining market share and becoming the industry's preferred material.
