It is observed by SEM that glass fiber has smooth surface, low crystallization, high density of fracture and shellfish veins of fracture obviously submits ditch form.
用SEM观察到玻璃纤维的表面光滑、低析晶、断口质密度高、断口贝纹呈明显沟状。
However, only the formation of cross-cutting plant fiber paper, there is a non-uniform density distribution, the surface is not smooth, highly absorbent and so on, can not be used in the printing.
然而仅用植物纤维相互交织形成的纸张，存在着密度分布不均匀、表面不平整、吸水极强等问题，不能在印刷中使用。
This series door facing is made of high density wood fiber. The surface with oak wood grain and be finished white primer painting.
此系列模压门板基材为高密度模压门板，表面为橡木纹理，喷涂的白色水性底漆。
