MH-300W木材基本密度專用比重計MH-300W Hydrometer
MH-300W木材基本密度專用比重計臺灣matsuhaku
技術數據:
1密度是認定木材物理特性、力學特性時的一個重要參數。也許可以說密度是唯一檢驗一塊木材力學性能的重要物理特性,也是質量認定的一項重要指標。木材是由一連串細胞、氣管胞、木質素細胞壁組成的一種生物。氣管細胞像管子,沿著樹莖運輸的液汁,使他們填補養分。木材的密度是一個非常有趣的變量,因為不同木材部位所量測的密度不同。
2許多木材密度定義,林業的測量是使用已被風干已知木材體積的重量。視各國對空氣干燥的規定不同:留在木材樣品水的部分可能是12 % ,或15 % 。木材密度在技術上定義為烘干的木材樣品重量除以生胚體積置換水的重量之比(木材的比重,或WSG),測量烘干的重量結合測量生胚體積是可以計算出來的。各部分支和外部樹干其密度往往比木材樹心為低,木材的密度值影響木材本身的吸濕性、收縮的程度、膨賬力學、熱量、聽覺、電力和其它基本特性。可見木材密度值的量測是何等的重要。

MH-300W wood basic density for MH-300W Hydrometerhydrometer
MH-300W wood basic density of Taiwan matsuhakuspecial hydrometer
Technical data:
1 density is an important parameter for determination ofwood physical properties, mechanical properties.Perhaps it can be said that the density is an important physical properties of a piece of wood mechanical properties only test, but also is an important index ofquality identification. Wood is a kind of biological cells, by a series of tracheal cell, the cell wall composition of lignin.Tracheal cells such as pipes, along the tree stemtransport sap, so that they fill the nutrient. Wood densityis a very interesting variables, because different parts ofthe measured density of wood.
2 many wood density is defined, forestry is measured using a known has been dried wood volume weight. As countries according to the regulations of the air driedwood samples of different: in part of the water may be 12%, or 15%. Wood density in the technology is defined as the drying of the wood sample weight divided by theembryo volume replacement water weight ratio (the proportion of wood, or WSG), embryo size measurementscan be calculated by measuring dry weight. Each branchand trunk of the external density than timber tree heart islow, influence of wood itself, hygroscopicity, degree of contraction, expansion mechanics, heat, sound, electricity and other basic characteristics of wood density. Visiblewood density measurement is very important.
