Resumen

POONIA, Pawan Kumar  y  TRIPATHI, Sadhna. Effect of microwave heating on ph and termite resistance of Pinus roxburghii wood. Maderas, Cienc. tecnol. [online]. 2018, vol.20, n.3, pp.499-504. ISSN 0718-221X.  http://dx.doi.org/10.4067/S0718-221X2018005031901.

This study investigated the effect of microwave treatment on wood pH and termite resistance. Pinus roxburghii heartwood was exposed to four different microwave intensities at 2450 MHz frequency for 5 minutes. Preservative impregnation, pH variation and termite resistance of microwave-treated and control specimens were studied. Wood pH decreased from 4,6 (C1) to 3,9 (T4) and preservative uptake increased (i.e., 10,41 to 21,61 kgm-3) with increasing microwave treatment intensities. However, microwave treatment had little effect on termite resistance.
