Electron Beam Curing
Electron beams are frequently used to initiate polymerization reactions and crosslinking of plastic materials. This process works by reacting liquid, uncured monomer substrates with highly accelerated electrons. This reaction instantaneously polymerizes the liquid monomer to a non-tacky, cured solid state.
Often, the EB chamber requires purging to eliminate any oxygen from air. Oxygen can be converted to ozone in the chamber, which can then attack unsaturated bonds. This may lead to less glossy finishes, or other adverse results. Linde can help you install and operate effective purging on your electron beam lines.
Electron beam technology is used in an extensive number of applications including:
Inks and Varnishes
Automotive Interior / Exterior Trim
Fiber Optics and Telecommunication Cable
It is often necessary to cool high pressure hose during manufacture to make the hose more rigid. This rigidity allows the layers of metal wire or high-tensile filament to be more uniformly applied before final vulcanization. While dry ice or a liquid bath can be tried, liquid nitrogen offers the best method for quality, efficiency and control.
Cooling with liquid nitrogen is accomplished in a chamber with a central tunnel. The hose passes through the tunnel and liquid nitrogen flows through an internal cooling spiral. The system design forces cold nitrogen gas back towards the tunnel entrance to precool the entering hose. Temperature control is automatic and adjustments are simple and fast acting.
Liquid nitrogen offers many advantages during hose cooling:
Production line speed increase
Lower operating cost versus other cooling methods
Adjustable temperatures for material type, hose size, etc.
Reduced wear on the weaving equipment since less tension is needed since upon warming the hose will expand to yield final braid tightness
Improved hose quality
Raw Material Quality
Have your raw materials ever discolored, absorbed moisture or degraded during storage?
Nitrogen gas could be the answer to your problems. Using nitrogen gas to displace oxygen and moisture provides a safe, dry environment for storage of valuable raw materials. Blanketing applications protect materials exposed to elevated temperatures from oxidation during processing and extrusion. Enhancing them in a nitrogen rich atmosphere and shielding them from moisture and oxygen, can improve the quality of your raw materials and the products made from them.
The cryogenic approach to this environmental problem is characterized by low investment costs and energy consumption. Controlling the consumption of liquid nitrogen is key to operating economics. A number of such plants are in operation around the world. Reference installations can be suggested and visited at any time
