Abstract
Methods of treating wood and wood products include irradiating untreated wood having a first molecular weight with ionizing radiation to cause an increase in the molecular weight of a cellulosic component of the wood to a second, relatively higher molecular weight.
Claims10
A method of treating wood, the method comprising:
- irradiating untreated wood having a first molecular weight with from about 0.25 to about 10 MRad of electron beam radiation, having an energy of about 2.5 to about 10 MeV, to increase the molecular weight of a cellulosic component of the wood to a second, relatively higher molecular weight at least about 10% higher than the first weight.
