Balsa wood-常識百科
輕木、白塞木(Balsa wood)
白塞木(balsa wood)又名輕木,產於非洲熱帶地區,是一種很輕的天然木材。在顯微鏡下,白塞木的細胞個體很大,但是細胞壁很薄。它的木質纖維僅佔總體積的40%,固態物含量極低。生長中的白塞木細胞中充滿了水,它的樹幹長得又直又硬,就好像被充滿了氣的汽車輪胎一樣。白塞木含水量相當於它自身木質纖維重量的5倍,被砍伐後要徹底烘乾,整個乾燥過程需要2週,直到木材的含水量達到6%。乾燥後的白塞木密度為385kg/m3。
白塞木是一種非常昂貴的木材,它通常只被少量地運用。當它被用於汽車製造業中,成為了美國汽車文化一個標誌。雪佛萊跑車誕辰五十週年紀念上的 Corvette汽車的地板是用白塞木的木芯製成的。這是一種類似於三明治結構的人造板。白塞木內部蜂窩狀的構造,不僅有效地降低了汽車的震動和噪音,而且還增強了汽車地板的強度。

在南美洲厄瓜多爾盛產輕木,一根又粗又長的木材,兩個人抬起來快步如飛。輕木比做軟木塞的栓皮櫟還要輕一半,是世界上最輕的樹木。每立方米僅重115公斤。一個正常的成年人可以抬起約等於自身體積8倍的輕木甚至更多。

Ecuador supplies 95% or more of commercial balsa. In recent years, about 60% of the balsa has been plantation-grown in densely packed patches of around 1000 trees per hectare (compared to about two to three per hectare in nature). It is evergreen or dry-season deciduous, with large (30–50 cm or 11.8–19.7 in) weakly palmately lobed leaves. Being a deciduous angiosperm, balsa is classified as a hardwood despite the wood itself being very soft. It is the softest commercial hardwood. The trees are harvested after six to 10 years of growth. The name balsa comes from the Spanish word for "raft".
