The market for thermally modified exterior products increased very rapidly as European consumers increasingly looked for alternatives to tropical woods from Asia, Africa and South America. A Turkish producer, Nova Wood, also started producing of thermally modified wood and became a minor player in European markets.
Alternative natural materials are natural materials like rock or adobe that are not as commonly used as materials such as wood or iron. Alternative natural materials have many practical uses in areas such as sustainable architecture and engineering. The main purpose of using such materials is to minimize the negative effects that built ...
In the furfurylation process, the walls of woody cells are initially swollen with the furfuryl-alcohol-based solution. Due to its polarity and size, furfuryl alcohol penetrates the cell wall. [ 3 ] The polymerization of furfuryl alcohol in wood is a complex reaction whose processes are not fully understood.
Acetylated wood is a type of modified wood that is produced through a chemical modification process and does not contain any toxic substances. [1] It produced from a chemical reaction (named as acetylation), involving acetic anhydride and a modification process to make wood highly resistant to biological attacks by fungi and wood-boring insects and durable to environmental conditions.
Posts and poles can be treated directly on endangered areas, but should be treated at least 30 cm (0.98 ft) above the future ground level. The depth obtained during regular steeping periods varies from 5 to 10 mm (0.20 to 0.39 in) up to 30 mm (1.2 in) by sap pine.
The bamboo must be treated to protect it against insects (namely beetles and termites). The most common and appropriate chemical to treat bamboo is boron, normally either a mixture of borax and boric acid , but it also comes in one compound (di-sodium tetraborate decahydrate).
