一种实验用长形刨花的制备方法

基于生产长形刨花的设备价格昂贵，提出一种实验用长形刨花的简易制备方法。以杉木Cuninghamia lanceolata生材为原料，采用平刨法和压刨法制备长形刨花，并对刨花尺寸和形态进行分析。结果表明：平刨法刨切的70mm长圆木段的刨花长度为60～80mm的占70％左右，压刨法刨切的90mm长的方材的刨花长度为80～100mm的约占55％；长度为70mm的刨花的形态系数约半数为100～150，90mm长的刨花形态系数约半数为200～300。因此2种方法所制得的刨花尺寸、形态系数等都符合实验要求，取适当长度的木块及调节合适的刀片伸出量即可生产各种规格的刨花。

Simple method for producing strand used in laboratory

In terms of the equipment to produce strand is extremely expensive,this paper presented a simple method for producing strand used in lab.The strands were made by planning slicing and pressure slicing with Cunninghamia lanceolata as material and their dimension and shape were analyzed.The results were as follows: the length of strand between 60 mm and 80 mm,made by planning slicing method from round wood 70 mm long,accounted for 70% or so while the length of strand between 80 mm and 100 mm,made by pressure slicing method from cant wood 90 mm long,accounted for about 55%.The shape coefficient of about half of the strand 70 mm long was between 100-150 and that of about half of the strand 90 mm long was between 200-300.In conclusion,the dimension and shape coefficient of the strands produced by this simple method were suitable for use in lab.Moreover,strand of different dimension and shape can be produced by using wood cant with certain size and adjusting the length of the blade.[Ch,7 fig.8 ref.]
