Overcome the problem of high corrosion transportation! !Zhengju New Materials' ultra-high molecular weight polyethylene pipes were successfully delivered to the Guizhou gold mine project.
Recently, a batch of customized ultra-high molecular weight polyethylene (UHMWPE) pipelines of Luoyang Zhengju New Materials Technology Co., Ltd. (hereinafter referred to as "Zhengju New Materials") have been produced, tested and loaded, and officially sent to a high-value gold mine project in Guizhou, which will be specially used for the highly corrosive mineral processing agent conveying system in the mining area, providing a core guarantee for the stable and safe operation of the gold ore dressing process.
Many gold mines in Guizhou are associated with complex geological conditions. The mineral processing links need to transport highly corrosive mineral processing reagents containing cyanide, thiourea and other components for a long time, and the pH value of the medium is large (strong acid is strong to alkaline). The long-term use of traditional steel pipes and ordinary PE pipes is prone to corrosion perforation, scaling blockage, aging leakage and other problems, and the average service life is less than 2 years. Frequent replacement not only pushes up the operation and maintenance costs, but also affects the mineral processing efficiency more easily due to shutdown and maintenance, and there is a risk of environmental leakage.
Aiming at the core requirements of "strong corrosion, continuous transportation, safety and environmental protection" of the project, Zhengju New Materials Technology Team has customized a high corrosion-resistant UHMWPE pipeline solution based on years of research and development experience of mine pipelines. The pipeline is made of ultra-high molecular weight polyethylene, which has three core advantages: extreme corrosion resistance and adaptability to strong corrosive media; the material has strong chemical stability, can withstand the corrosion of acid and alkali media with pH of 2-13 for a long time, and is perfectly suitable for the transportation of strong corrosive fluids such as gold ore dressing and leaching solution, thus eliminating the hidden danger of corrosion perforation of metal pipelines from the root.
| Project Parameter | Traditional Steel / Regular PE Pipes | Zhengju Customized UHMWPE Pipeline |
|---|---|---|
| Chemical pH Range | Poor resistance (Prone to perforation) | pH 2 - 13 Long-term resistance |
| Wear Performance | Rapid friction thinning | 4 - 7 times higher than carbon steel |
| Average Lifespan | Less than 2 years | More than 10 years service life |
| Structural Weight | Heavy (Requires heavy equipment) | Only 1/8 weight of steel pipes |
| Scaling & Blockage | High risk of scaling & mud hanging | Smooth inner wall, zero scaling blockage |
Wear-resistant and anti-manufacturing, extending service life: the wear-resistant performance is 4-7 times that of ordinary steel pipes, and the inner wall is smooth without scaling and mud hanging, and the mineral processing agent containing trace solid particles is not easy to wear after long-term transportation, and the service life can reach more than 10 years, greatly reducing the replacement frequency. Light weight and safety, convenient installation, operation and maintenance: the weight is only 1/8 of that of steel pipe, so it can be transported and installed without large equipment, and it is connected by special joints without hot work, which is suitable for complex construction environment in mining area; At the same time, the material has no metal ion precipitation, which avoids the secondary pollution of mineral processing agent and meets the requirements of environmental protection.
This order was efficiently promoted from technical docking, scheme customization to production delivery. Zhengju New Materials relies on three automatic production lines with an annual production capacity of 500,000 meters, and strictly implements 12 quality inspection procedures to ensure that the wall thickness, pressure resistance and corrosion resistance of each batch of pipes meet the standards and successfully pass the on-site acceptance of the project party.
As a backbone enterprise in the field of mine polymer pipelines in China, we are raising new materials and deeply cultivating ultra-high polymer materials for many years. Our products have been widely used in industrial and mining scenes such as gold mines, copper mines and tailings transportation, and accumulated more than 100 mine anti-corrosion transportation projects. The successful delivery of the gold mine project in Guizhou once again confirmed the company's technical strength and delivery ability in the field of highly corrosive and wear-resistant industrial and mining pipelines. In the future, Zhengju New Materials will continue to focus on the pain points of the mining industry, increase the R&D and innovation of polymer materials pipelines, provide more efficient, durable and environmentally friendly pipeline transportation solutions for more high-value mineral projects, and help the mining industry to reduce costs and increase efficiency. Green development.
