符合 ASTM D5470 國際標準
使用穩態熱板法量測熱傳導係數,操作簡單、量測快速
三種樣品模式自動量測:高黏度液體、黏彈性固體、固體
適用在各種固體材料 :薄膜、高分子、金屬





使用穩態熱板法量測熱傳導係數:

上下兩個平板間放置固定面積A的樣品,並於樣品施加一定的熱流量Q及壓力,在不同的點位(T1,T2,T3,T4)間測量通過樣品的熱流、並依據不同壓力下的樣品厚度d、熱板/ 冷板間的溫度梯度slope,可計算出不同厚度下對應的熱阻值R並以迴歸分析得出樣品的導熱係數K。

依據 ASTM-D5470 標準, 三種樣品模式自動量測:
I.   高黏度液體Viscous liquids
II.  黏彈性固體Viscoelastic solids
III. 彈性固體Elastic solids

ASTM D5470 is useful for measuring the thermal impedance of the following material types.
Type I—
Viscous liquids that exhibit unlimited deformation when a stress is applied. These include liquid compounds such as greases, pastes, and phase change materials. These materials exhibit no evidence of elastic behavior or the tendency to return to initial shape after deflection stresses are removed.

Type II—Viscoelastic solids where stresses of deformation are ultimately balanced by internal material stresses thus limiting further deformation. Examples include gels, soft, and hard rubbers. These materials exhibit linear elastic properties with significant deflection relative to material thickness.

Type III—Elastic solids which exhibit negligible deflection. Examples include ceramics, metals, and some types of plastics.


可多點、即時溫度感測
