Preservative treatement of muli bamboo (Melocanna baccifera) by pressure process
2001 - IRG/WP 01-40194
This study was carried out in order to investigate the possibility of preservative treatment of split bamboo by pressure process. Whole bamboo is very difficult to treat by pressure process, which is the best and most dependable of all treating processes. Because it surface has a coat of impervious cutiular which make it very resistance to the penetration of liquid. Beside this it is prone to deve...

Treatability and natural durability of some lesser used or unused wood species of Bangladesh
2000 - IRG/WP 00-40170
A research study was conducted to determine the natural durability and treatability of heartwood of some lesser used or unused wood species. The treatability of species has been studied along with certain anatomical concepts association with preservative penetrability of the wood. It was observed that grain structure and presence of tyloses appeared to be correlated with penetrability of the wood....

Preservative treatment of different thatching materials for low cost housing
1999 - IRG/WP 99-40144
Preservative treatment were made in seven different roofing materials with Copper-Chrome-Boron (CCB) at different concentration by soaking process. These were paddy straw, wheat straw, jute stick, sungrass, ulu grass, sugercane leaf and Nipa fruticans. It was observed that retention of preservative chemicals varies from species to species at the same concentration. From the service test it was obs...

Preservative treatment of Gollah cane (Daemonorops jenkinsiana) by soaking method
2001 - IRG/WP 01-40197
The feasibility of preservative treatment of gollah cane (Daemonorops jenkinsiana (Griff.) Mart.) by soaking method was tested in the present study. Cane samples of 1m, 2m and 3m long were soaked with 10% borax and boric acid solution. The study revealed that adequate dry salt retention (DSR) in the above samples could be obtained in 3 days, 4 days and 5 days of soaking, respectively. Within these...

CCB Preservative treatment of split muli (Melocanna baccifera ) bamboo by soaking process
2006 - IRG/WP 06-40336
This study was carried out in order to investigate the retention of chemicals inside the split muli ( Melocanna baccifera ) bamboo after preservative treatment by soaking process. Treatment with 10% aqueous solution of CCB (copper-chrome-boron) was applied in split bamboo of two sizes (1/4 part and 1/8 part) at three different moisture contents and five time periods (24, 48, 72, 96, 120 hours). It...

Preservative treatment of Golla cane (Daemonorops jenkinsiana) by pressure process
2007 - IRG/WP 07-40379
The feasibility of preservative treatment of golla cane (Daemonorops jenkinsiana (Griff) Mart). by pressure process has been studied using water borne preservatives CCB (copper-chrome-boron). Cane samples of three different lengths 1m, 2m and 3 m. were treated at different pressure and time period to evaluate the extent of penetration and retention of preservative chemicals. It was observed that t...

Preservative treatment of strips of Bambusa balcooa by soaking process using Borax-Boric acid
2008 - IRG/WP 08-30478
Bamboo strips made from Borak bamboo (Bambusa balcooa) were treated with 10% borax-boric acid aqueous solution by soaking process. The moisture contents of the bamboo strips were 12%, 20% and 30%. The strips were soaked for one, two, three, four and five days. The penetration of the solution was investigated by colour test after soaking and drying. Full penetration was observed after three days ...

Photostabilization of Wood with Higher Molecular Weight UV Absorbers
2010 - IRG/WP 10-30524
Higher molecular weight UV absorbers were created by reacting the epoxy-functionalized UV absorber 2-hydroxy-4(2,3-epoxypropoxy)-benzophenone (HEPBP) with maleic, phthalic or succinic anhydride. The ability of the UV absorbers to photostabilize wood was then examined. FTIR-spectroscopy confirmed that HEPBP reacted with phthalic anhydride to create a polyester that preserved the UV-absorbing benzop...

Development of composite furniture using bamboo strips, bamboo mat and rubber wood veneer
2014 - IRG/WP 14-40679
Bamboo offers cost-effective component in panel form is well suited to wood substitute can be used as furniture components. In the present study, borak (Bambusa balcooa ) bamboo were used for manufacturing bamboo panel. Mitinga (B. tulda) bamboo were used for making mat and rubber wood veneers were used for manufacturing mat overlaid veneer board. Borax-boric acid (BB) treatments were given to enh...
