經(jīng)由TMA獲得的材料特性信息對于各式產(chǎn)品的設(shè)計及制程卻極為重要,舉凡電子芯片封裝、電路板、高分子材料、纖維染色到引擎的設(shè)計等,各種其尺寸會隨溫度而變化的產(chǎn)品,TMA都是*的重要儀器。
廣泛的應(yīng)用范圍
TMA的施力范圍從0.01mN 至 5.8N,能提供極廣的樣品種類分析,當(dāng)然包括須施加較大力量的軟化點測試,從單一纖維質(zhì)到高密度復(fù)合材質(zhì)皆可適用。對于加溫過程尺寸變化非常高的樣品,如纖維或薄膜等可以提供±5000 μm的位移范圍,讓儀器足以在尺寸變化極大的情況下進(jìn)行連續(xù)性的監(jiān)測與應(yīng)用分析。
TMA 可以測得以下各項數(shù)據(jù):
- 楊氏系數(shù) Young’s modulus
- 陶磁燒結(jié) Sinterine
- 機(jī)械黏彈性質(zhì) Modulus / Viscosity & tan δ
- 壓力復(fù)原 Stress-relaxation
- 應(yīng)力應(yīng)變 Stress-strain
- 潛變值 Creep
- 膠化時間 Gel time
- 剝離時間 Peeling time
- 收縮點 Shrinking
- 軟化點 Softening
- 玻璃移轉(zhuǎn)溫度 Glass transition Temperature
- 膨脹系數(shù) CTE (Coefficient of Thermal Expansion)
