Decay Resistance and Physical Properties of Oil Heat Treated Aspen Wood
The decay resistance of oil-heat treated aspen wood (Populus tremula l.) against white rot fungi (Coriolus versicolor) and brown rot fungi (Coniophora puteana) was investigated. Three different temperature stages and two time levels for oil heat treatment for the selection of optimum conditions were determined. Linseed oil as a heating medium was used. The mass loss of treated samples that were...
متن کاملChemical Modification of Pine Wood with Propionic Anhydride: Effect on Decay Resistance and Sorption of Water Vapour
The purpose of this paper is to show the effects of level of substitution with a linear chain anhydride (propionic anhydride) on decay resistance and on water vapour sorption of modified Scots pine sapwood. The work described herein has demonstrated that chemically modified Scots pine sapwood with propionic anhydride afforded substantial bioprotection against Coniophora puteana. It required a w...
متن کاملCopper Complexes Grafted to Amino-functionalized Silica Gel as Wood Preservatives against Fungal Decay: Mini-blocks and Standard Test
Previous preliminary studies showed good efficacy of treatments based on a mixture of siloxane materials, functionalized with amino groups and coupled with copper, against the brown rot fungus Coniophora puteana (Palanti et al. 2011). In the present work, a one-step impregnation was performed on two sets of samples differing in size, in order to verify and compare the homogeneity of treatments....
متن کاملStudy of Dimensional Stability, Decay Resistance, and Light Stability of Phenylisothiocyanate Modified Rubberwood
Rubber wood (Hevea brasiliensis) was esterfied with phenylisothiocyanate, and dimensional stability, decay resistance, and photo stability of the modified wood was assessed. The chemically modified wood was characterized by FTIR and CP/MAS C NMR spectroscopy. Unmodified and modified samples were exposed to a brown rot (Polyporus meliae) and a white rot (Coriolus versicolor) fungus for 12 weeks....
متن کاملDecay mechanisms of brown-rot fungi
Brown-rot fungi, e.g. the dryrot fungus (Serpula lacrymans), are the most harmful microorganisms in wood in service in Finland and in temperate regions. Brownrot fungi cause wood decay primarly by attacking the carbohydrates of the cell walls, leaving lignin essentially undigested. At the initial stage of the decay, the brown-rot fungi seem to operate by a mechanism which cause extensive change...
