Challenge the extreme cold zone! Russia independently develops low-temperature silicone oil to solve the problem of Arctic equipment
——Ultra-low temperature lubrication technology promotes resource development in the cold economic zone
Facing the extremely cold climate of -60℃ in Siberia, mechanical equipment has difficulty starting and lubrication failure has always been a "neck-breaking" problem that restricts the development of Russian Arctic resources. Recently, the low-temperature silicone oil jointly developed by Russian local enterprises and European materials laboratories was officially put into production, marking a new era for cold zone equipment technology.
Core technology: Molecular structure innovation achieves ultra-low temperature fluidity at -80℃
The viscosity of traditional mineral oil rises sharply to 10^5 mPa·s at -40℃, while the silicone oil is compounded with branched siloxane molecules and low-temperature plasticizers, and the viscosity remains below 3000 mPa·s at -80℃, and the oil film strength is increased to the L-XCCHA level of ISO 6743-9 standard. In the field verification at the Yakutsk Polar Test Station, the cold start time of the transport vehicle gearbox equipped with this silicone oil was shortened to 8 seconds at -65℃, which is 80% more efficient than traditional lubricants.
Application scenarios: Comprehensive empowerment from oil and gas pipelines to polar scientific research
At present, the product has been supplied in batches to the snowmobiles, drilling platform hydraulic systems and Nord Stream natural gas pipeline cryogenic pumping stations of the "Arctic-2024" scientific expedition team. Its anti-freezing properties can ensure that the valve can be opened and closed 20 times per second in extreme environments, ensuring the stability of energy transmission. In addition, the product has passed the ROHS certification, meeting the EU's environmental protection requirements, and clearing technical barriers for Russian equipment exports to the European market.
Strategic significance: A key step in breaking the Western technological blockade
"Previously, 95% of special lubricants for cold regions relied on imports, and our product costs are only 60% of similar products in Europe and the United States." Anna Ivanova, chief scientist of the project, emphasized. It is reported that the Russian Ministry of Industry and Trade has included this technology in the priority procurement catalog of the "2030 Polar Development Strategy", and it is expected that the production capacity will be expanded to 5,000 tons/year in 2025, covering 85% of the demand for cold-region industrial equipment in Russia.
