Durability of Bamboos in India against termites and fungi and chemical treatments for its enhancement
2005 - IRG/WP 05-10553
Bamboo is a very important forest resource that benefits the life of people in a myriad ways including meeting the need for structural uses like posts, pole fencing, scaffoldings, house building, etc. Although it is one of the strongest structural material available, often succumbs to fungal decay and biodeterioration by insects (termites and powder post beetles) during storage and usage. Studies...

The evaluation of the effectiveness of wood preservatives by means of IUFRO's method for field tests with wooden stakes
1985 - IRG/WP 3348
Pinus elliottii and Eucalyptus saligna stakes treated with CCA-A, CCA-C, CCB, Cashew Nut Shell Oil and Benzotar solutions were exposed in seven test sites in Sao Paulo State, Brazil. After five years of exposure, between oil-borne preservatives Benzotar show better performance than CNSL (cashew nut shell liquid), and within waterborne preservatives the performance of CCB is not so good as that of ...

Evaluation of copperised Cashew nut shell liquid and Neem oil as wood preservatives
2005 - IRG/WP 05-30368
An effort has been made to develop eco-friendly wood preservatives using naturally available plant by-products with less toxicity. Copper was incorporated into Cashew nut shell liquid (CNSL) and Neem seed oil. Rubber wood samples were treated with these solutions employing dipping and pressure techniques in 3 different levels. These samples have been evaluated to find out the effectiveness as wood...

Effectiveness of wood preservatives by IUFRO's method
1984 - IRG/WP 3305
Pinus elliottii and Eucalyptus saligna stakes treated with 4.9; 6.9; 9.6 and 13.5 kg/m³ of CCA-A, CCA-C and CCB and with 30-50; 60-80; 90-110 and 120-140 kg/m³ of Benzotar and CNSL (cashew-nut shell liquid) were exposed in seven test sites in Sao Paulo State, Brazil. After 4 years it was concluded that the mean useful life of untreated Pinus elliottii stakes was 8 months and of untreated Eucalyp...

Composition of urushiol and cardanol from Japanese lacquer tree and related origins
1991 - IRG/WP 3667
Wood may be protected against insects and weathering based on the paints. Japan has been used to protect wood from weathering, insects, checking that ordinarily develop when unprotected wood is exposed to the weather. Japaned wood gives a hard, durable, various gloss especially black. The yield of culture-urus hiol obtained from Japanese lacquer tree (Rhus vermiciflua Stokes) was 0.6% based on the...

Durability of timber from exotic species against termite attack in Indian conditions
2007 - IRG/WP 07-10629
Exotic trees species, Acacia mangium Willd. and A. auriculiformis A. Cunn. ex Benth. and their hybrid are widely grown in India for multiple uses including use as timber. It is essential to know the natural durability of timbers against termites for predicting the service life of the timber and deciding on the application of preservatives to enhance the durability. Studies were conducted to test t...

Effect of bio-resin from cashew nut shell liquid (CNSL) on decay resistance properties of wood
2013 - IRG/WP 13-40649
This study assesses the decay resistance properties of bio-resin modified wood against decay fungi of the Basidiomycota according to the EN 113 protocol. A bio-resin system was developed by ozonolysis process from cashew nut shell liquid (CNSL), a naturally occurring mixture of phenolics. Small wood blocks from sapwood of Scots pine (Pinus sylvestris), Obeche (Triplochiton scleroxylon) and Gmelina...

Liquefaction of woody waste: A novel approach in wood protection from CNSL based liquefied wood polyols
2017 - IRG/WP 17-30711
Liquefaction of lingo-cellulosic biomass is one of the thermo-chemical conversion processes for developing new materials, adhesives, preservatives and energy systems. The process also provides an opportunity to utilize waste wood such as saw-dust, woody wastes, branches and twigs for the development of value added products. Thus, this research paper deals with an investigation of antifungal and a...
