商品說明資料

SST系列纖維定向測試儀採用超音波技術，用於分析薄片的纖維/分子的定向，如紙張和塑料薄膜。 SST分析結果與代表抗張挺度的楊式彈性模量有良好的相關性。對紙張和薄膜而言，無論是在高速精確的彩色印刷過程中保持良好的運行性，還是高強瓦楞紙箱結構的加工等，抗張挺度和纖維/分子的定向性都是非常重要的指標。 TSI和TSO的定義 SST採用8對超聲波發射器和傳感器，測量超聲波脈衝在紙張中16個方向（每個方向的角度為11.25°）傳播速度，並計算每個方向傳播速度V（km/s）的平方。因為V²與楊式彈性模量有良好的相關性，因此，SST的抗張挺度指數定義如下：「TSI＝V²」，紙機方向抗張挺度指數為TSImd，紙幅橫向的抗張挺度指數為TSIcd。另外，SST還能計算最大TSI方向和最小TSI方向的抗張挺度定向角度「TSOpeak」和「TSOdeep」所有的測試操作和數據分析都通過裝有WindowsXP操作系統的筆記本電腦完成。 A4（21×29.7cm）紙大小或相近尺寸的單張薄片適用於單片測量模式。開始測試15s後，所有關鍵測量數值和橢圓形指示圖都會顯示在螢幕上。橫向圖像的測量可用自動進樣器選件完成。測試圖像可在螢幕上顯示，測量長度間隔可在10－1000mm間選擇。較長的縱向試樣也可選用自動進樣器附件測試。測量長度間隔可在10－1000mm間選擇。最多可以測試65000個點。規格：尺寸：D420×W240×H250mm（10.5Kg）電源：AC 100－240V 50/60Hz 100W 氣源：0.3-0.6MPa，1 L/min 測試元件數：16 測試角度間隔：11.25° 超聲波的路程：120mm 測試速度範圍：0.75-500km/s 測試速度精確度：±0.3% 測試角度精確度：±0.5° 測試時間：大約13s FD-1自動進樣器（選配）尺寸：D550×W550×H128mm（14.5Kg）進樣速度：100mm/s 進樣精確度：±0.5%(1000mm內) FD-1自動進樣器

SST-4000 / Manufactuerd by NOMURA SHOJI Ultra Sonic Fiber & Molecular Orientation Tester SST-4000 is a fiber/molecular orientation measuring equipment based on ultrasonic technique Since starting to sell in 1983, SST series has been turned over 400 or more sets in the paper and the film manufacture industry in the world and has obtained high evaluation as a measuring instrument of the quality control. Fiber/Molecular Orientation affects the greatly curl, the twist, the size modification and the mechanical strength, and determines the quality of paper. This is an important factor. SST-4000 makes it possible to manufacture the high quality paper and film. FEATURE Orientation measurement of Tensile Stiffness (fiber/molecule) Stable measurement technology with plenty of experience * High robust measurement by ultrasonic * Stable high precision measurement by ultrasonic * High-speed measurement by multi- ultrasonic sensors Fusion of a personal computer and a measuring instrument * User-friendly man machine interface * Visually screen display / report * Facile data storage/ data processing * Facile measurement data analysis by store-bought S/W (Excel etc.) Automatic profile measurement of Long sample with a FD-1 Feeding Device (option ) Ease of maintenance PRINCIPLE Ultrasonic pulse transmits in a paper or film sheet of density “ρ “with speed “C” for a fixed length “L” in a certain time “T”. Then Young’s modulus “E” can be described by the following formula. [ Formula ] SST measures T in msec or C in Km/sec by 11.25 degree interval for 360 degree, calculates fiber (molecular) orientation/ cross-length ratio/ peak values (max and min)/ tensile stiffness index, and presents graphical and numerical results as below.
