Technology turns bad wood into good wood

The reserves of planted timber such as pine, cashew and rubber in our country are very large. However, the basic volume, mechanical properties, hardness of these woods is very low, at only 154 kg / cm ^3, so it is difficult to produce furniture for other industries.

Dr Hoang Thi Thanh Huong from HCM University of Agriculture and Forestry used methods of thermodynamics, thermal chemistry and chemistry to denature them. Accordingly, rubber wood, wood is applied thermal mechanical methods to increase durability; For hips, thermoplastic. It is also possible to convert rubber wood and chemical by-products.

The results show that the static bending strength of wood has increased from 30 to 50%: rubber from 963 kg / cm3 increased to 1287 kg / cm ³ ; from 843 kg / cm ³ increased to 1151.82 kg / m ³ ; hips from 449 kg / cm ³ to 720 kg / cm ³ .

This technology is also used to modify many types of light wood, not sustainable to supply the market and export.
