On August 1, 2018, the German specialty chemicals company LANXESS brought the polyurethane application solution to the 16th China International Polyurethane Exhibition. From ATM machines to roller coasters, from wind power to mining and transportation, exhibited polyurethane system products. Both are receiving attention.
'Polyurethane applications have high requirements for abrasion resistance, scratch resistance, chemical resistance and UV resistance. LANXESS offers a wide range of customized high performance solutions,' LANXESS Polyurethane Systems Business Unit (URE The head of the survey, Dr. Markus Eckert, said, 'analytical work, formulation development and synthesis of innovative products enable us to meet market demands with highly differentiated technologies.'
Stick to the precision and wear-resistant lifeline
One of the highlights of the LANXESS booth is the ATM roller. In our everyday ATM machines, the banknote and the roller are critical components that require high dimensional stability and hardness stability. Polyurethane materials, especially those from LANXESS, meet these needs with their heat and antistatic properties, ensuring an accurate and unpredictable access to 8 million banknotes – 5 sheets per second The speed of the banknotes is issued, and the banknotes do not stick to each other.
In our daily ATM machines, the banknote and the banknote roller are vital components. They have high requirements for dimensional stability and hardness stability.
As a key exhibit of the LANXESS booth, the polyurethane system's low free Adiprene polyurethane prepolymer, Vibrathane polyurethane prepolymer is also widely used in the wheels of modern high speed roller coasters. The wheels of this material have lower endogenous in operation. Heat and better fatigue resistance, which avoids excessive temperature inside the wheel and stress cracking under heavy load, which can withstand higher loads and higher speeds to ensure that the body is safely fixed in these Awesome steel track.
Hot-cast polyurethane absorbs less energy during deformation and produces lower heat (low hysteresis). This avoids excessive wheel temperatures and can withstand higher loads and higher speeds to ensure the body is Securely fixed on these formidable steel tracks.
Make green energy more convenient
LANXESS polyurethane systems also provide protection and securing of submarine cables for offshore wind turbines. In extremely harsh environments, submarine cables must resist corrosion and wear, as well as the impact of scattered ocean currents. In offshore platforms, polyurethane materials can satisfy pipelines. Bending restrictions, risers, hose bending stress protection, subsea tubing, cable fixing and other application requirements.
In offshore oil platforms, polyurethane materials can meet the application requirements of pipeline bending limits, risers, hose bending stress protection, subsea tubing, cable fixing and other applications.
Sea ceiling and cable housing
Take the two polyurethane systems Adiprene and Vibrathane highlighted by LANXESS as examples. These products have excellent wear resistance, tear resistance and high resilience. They can be used in mining, ore dressing, tailings processing, etc. Working conditions, and easy to process. Therefore, it is widely used in equipment sealing (including hydraulic bracket sealing, engineering mechanical seal), screen (fine screen, relaxation screen, dewatering screen, ordinary sieve), cleaner (low speed sweeper, High-speed cleaner), pipe lining, cyclone, etc. For example, the sweeper is used to scrape the dust and powder material adhered to the coal on the conveyor belt, while the polyurethane scraper in the cleaner is highly resistant. Grinding, aging resistant, solvent resistant, and long service life, these components can increase production efficiency while reducing maintenance costs as the service life increases.
LANXESS' polyurethane systems are widely used for equipment sealing (including hydraulic support seals, engineering mechanical seals), screens (fine screens, relaxation screens, dewatering screens, common screens), cleaners (low speed cleaners, high speed cleaners) , pipe lining, cyclone and so on.
Customized solution
The product categories offered by LANXESS Polyurethane Systems include: Hot-cast polyurethane systems covering prepolymers, chain extenders and additives, special waterborne polyurethane dispersants (PUD), for surface coatings, adhesives and sealants. End-capped prepolymers and additives (USC), special thermoplastic polyurethane elastomers (TPU), special polyester polyols. LANXESS's carefully designed systems are designed to withstand the toughest environments and show extraordinary dynamics in related applications. performance.
Liu Shengqiang, Vice President, Asia Pacific, LANXESS Polyurethanes Business Unit, said: 'Langsheng is already a partner and supplier of component processors and application developers in the Asia Pacific region. In the future, LANXESS Polyurethane Systems will rely on our Nanjing Application Development Center, USA. The Nogtag R&D Center, as well as a new laboratory for the development and application of polyurethane dispersion applications in Italy, to better develop customized solutions for customer needs.
Polyurethane is an elastic material between rubber and plastic, which has high elasticity of rubber and high strength of plastic. It has large elongation and wide hardness range; its wear resistance is particularly prominent. It also has excellent oil resistance, impact resistance, low temperature resistance, radiation resistance and load bearing, heat insulation, insulation and so on. Just as this, polyurethane is a versatile material that can truly meet various special requirements, in industry, mining, Transportation, electronics, energy, tires, construction, paper, consumer goods and even the healthcare industry can see it.
