HOW ELECTRON BEAM WORKS
Electron Beam (EB) processing is extremely precise and can be controlled and measured to provide the exact level of cure desired. Both the dose (the amount of electrons) and the depth of penetration can be precisely controlled. This is done with a computerized system that controls the dose and penetration depth of the electrons.
High voltage is applied to tungsten filaments inside a vacuum chamber. Filaments are super-heated electrically to generate a cloud of electrons. Electrons are drawn from the cloud and accelerated to extremely high speeds. Accelerated electrons pass through a foil window to penetrate the target product. Electrons cause desired molecular changes in the product.
EB CURING IS BOTH
PRECISE & MEASURABLE
HOW FILM CROSSLINKING WORKS
Upon absorbing the electrons, polyethylene molecules form free radicals. These free radicals are postulated to be formed on adjacent chains, accompanied by the loss of hydrogen molecules, known as the hydrogen abstraction process. Hydrogen gas is liberated upon cross-linking, and the polymer radicals combine readily to form a three-dimensional network, as shown in Figures 2A, 2B and 2C.
