The assessment by visual grading, change of color and ergosterol content ratings, the resistance to mould fungi of treated with wood preservative Scots pine sapwood
2013 - IRG/WP 13-20514
The filamentous (mould) fungi belonging to Ascomycetes, Deuteromycetes group are an cosmopolitan organisms which attacks wooden elements disfiguring them, dropping their value and causing environmental and health hazard. The fungi in a short time cause mainly disfigurement of wood does not effect on strength properties of wood, but with strong prolongation of duration of conditions favourable for ...

Assessment of Scots pine sapwood susceptibility to moulds by determination of fungi growth and ergosterol content in infested wood
2014 - IRG/WP 14-20540
The susceptibility of wood to filamentous fungi (mould) attack is determine mainly by laboratory methods with descriptive grading of fungal growth on the surface of the wood specimens. It is a lot of different grading scale of fungi growth, but determination of the size of fungi growth is many times not easy, not clear and often difficult. Although the filamentous fungi are not included to microor...

Comparison of gauge and assay retention in crossties treated with copper naphthenate
2014 - IRG/WP 14-40667
Creosote has been the most widely used preservative for wooden railroad crossties or sleepers for over 100 years. Alternative preservatives such as copper naphthenate (CuN) have been shown to provide equivalent performance against decay fungi and wood destroying insects; however, the use and specification of CuN involves an education process for treaters and railroad customers alike. One differe...

Antifungal properties of wood treated with IPBC and organosilicone compounds against Coniophora puteana
2015 - IRG/WP 15-30676
The aim of the research was to increase durability of Scots pine wood treated with 3-Iodo-2-propynyl butylcarbamate (IPBC) through organosilicon compounds. The IPBC was combined with organosilicon compounds (alkylsilane and alkylsilane with amino groups) for supporting its antifungal properties. The mycological examination against Coniophora puteana was performed to determine the resistance of woo...

Wood Protection Using Nano Metal Oxides in Propylene Glycol
2022 - IRG/WP 22-30760
Metals and metal oxides are known to have properties that can protect wood from degradation. Nanoparticles, due to its unique physical and chemical properties can enhance the protection to a much greater extent. Major constraints in dealing with nanoparticle dispersion can only be resolved by identifying a proper dispersive medium. Studies were carried out by preparing nanodispersion of four metal...
