黑胡桃木皮分直纹和花纹吗
分直纹和花纹。
黑胡桃木通常为直纹,亦会带有波纹状或卷曲纹理,产生好看具装饰效果的花纹。黑胡桃木皮呈浅黑褐色带紫色,弦切面为美丽的大抛物线花纹。深色的黑胡桃木皮体现沉稳,理性。北美黑胡桃木以直纹理、波形纹理以及卷曲纹理为主。黑胡桃木的高辨析度也体现在花纹上。
黑胡桃木发展及分布
黑胡桃,又名黑核桃,生长良好的胡桃木平均高度20-30m,直径1m-1.5m,黑胡桃木心边材区分明显,边材浅黄褐色至浅栗褐色,心材红褐色至栗褐色,有时带紫色,间有深色条纹,久露空气呈现巧克力色,生长轮明显,半散孔材。
侵填体常见,木射线细,放大镜下明显,轴向薄壁组织放大镜下明显,径切面上有射线斑纹,波痕未见。木材强度和韧性中等,并具有优良的加工性能。木材切面光滑,胶接,油漆性能好,是制作高档家具和室内装饰,装修的上等材料。
原木木材盛产于北美洲,北欧等地,东南亚地区也有广泛种植。其片材面具光泽,无特殊气味和滋味,纹理直,结构细至略粗,均匀。黑胡桃经刨切出来的木皮常常用于建筑工程木造部分及高级教室家具上。
木皮刨切的原木纹理分为两种。一种是直纹木皮,一种是山纹木皮(也有叫花纹木皮)。这个主要是根据原木纹理及大小有关。山纹木皮一般是一根原木去皮后开始刨切。直纹是把木头1/2开后开始刨切。直纹木皮纹理就是条纹直的,花纹木皮有直有花纹,花纹木皮中很多纹理想一座座山峰重叠,所以叫做山纹。希望可以帮到你!
欧洲山纹(英文)
The half log, or flitch , is mounted with the heart side flat against the
flitch table of the slicer and the slicing is done parallel to a line through
the center of the log. This produces a distinct figure.

Rift Cut(OAK)
Rift cut veneer is produced in the various species of Oak. Oak has medullary
ray cells which radiate from the center of the log. The rift or comb grain
effect is obtained by cutting at an angle of about 15% off of the quartered
position to avoid the flake figure of the medullary rays.

Quarter Sliced
The quarter log or flitch is mounted on the flitch table so that the growth
rings of the log strike the knife at approximately right angles, producing a
series of stripes, straight in some woods, varied in others.
