符合 ASTM D5470 国际标准
使用稳态热板法量测热传导系数,操作简单、量测快速
三种样品模式自动量测:高黏度液体、黏弹性固体、固体
适用在各种固体材料 :薄膜、高分子、金属





使用稳态热板法量测热传导系数:

上下两个平板间放置固定面积A的样品,并於样品施加一定的热流量Q及压力,在不同的点位(T1,T2,T3,T4)间测量通过样品的热流、并依据不同压力下的样品厚度d、热板/ 冷板间的温度梯度slope,可计算出不同厚度下对应的热阻值R并以回归分析得出样品的导热系数K。

依据 ASTM-D5470 标准, 三种样品模式自动量测:
I.   高黏度液体Viscous liquids
II.  黏弹性固体Viscoelastic solids
III. 弹性固体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.


可多点、即时温度感测
