Tali (wood)
Tali is the name for a type of wood that is made from the African tree species Erythrophleum suaveolens (Syn. E. guineense ), also Sasswood and Erythrophleum ivorense (Syn. E. micranthum ). In the English-speaking world, the wood of both types is also known as "Missanda".
features
They are evergreen trees from the legume family that reach heights of 20 to 40 meters. The slightly crooked and often out-of-round trunks usually have a trunk diameter of 1.20 meters. The heartwood is yellow-reddish to dark red-brown or copper-colored. The sapwood is light gray to pale brownish and approx. 3–6 cm wide and the smooth surfaces have a matt sheen.
distribution
The species are particularly widespread in West, Central and East Africa, i.e. all countries in Africa with tropical forest cover, especially Ivory Coast , Gabon , Ghana , Cameroon , Congo , Mozambique , Zambia and the Democratic Republic of the Congo .
properties
The wood is very durable and resistant to fungi, insects and burrs (resistance class I-II according to DIN-EN 350-2), even in direct contact with the ground. It contains little to no insect feeding holes ( pinholes ). The wood is twisted and does not contain resin, but it does contain oily and greasy ingredients that make surface treatment difficult. The surface should be degreased before treatment with solvents, and compliance with a weathering period is recommended. The surface can then be treated with solvent-based oil. A surface treatment on an aqueous basis does not promise much success. The swelling and shrinking behavior is so pronounced that it has to be taken into account in designs. The bulk density is around 900 kg / m³.
toxicology
Processing dust is biologically effective and can irritate the mucous membranes and cause general disturbances or paralysis. The juices of the bark are poisonous.
use
Tali wood is offered on the European market as parquet frieze, mosaic parquet, strip parquet, plank and prefabricated parquet, as well as thresholds and decking.
trade
Like all tropical timber, trade is subject to the import regulations of the Timber Safety Act (HolzSiG).
Species protection
There are no trade restrictions based on the CITES list (Convention on International Trade in Endangered Species of Wild Fauna and Flora, CITES for short, German Convention on International Trade in Endangered Species of Wild Fauna and Flora) or the Washington Convention on the Protection of Species.
