spinnerette

Through threshold transforming , dilation and area labeling of the source image which , input into computer by scanner , contains the information of the whole spinneret , the system can compute locations of every micro - hole . then the pickup camera equipped with microscope is moved on every micro - hole driven by step - by - step motors . the image of the micro - hole is captured to the computer after auto - focusing 該系統經過對掃描儀掃入的整塊的噴絲板圖像進行閾值處理、圖像膨脹、區域標記等圖像處理的手段分析出各個微孔的分布情況,然后用步進電機驅動加有高倍顯微鏡的攝像頭自動搜尋到每個微孔,對微孔自動的聚好焦后,采集微孔圖像。

The simulation results show that the shaped degree is decreasing when the spinning temperature and intrinsic viscosity are increasing ; the spinning speed has little effect on the shaped degree when the pump mass throughput is constant ; the shaped degree is increasing with the increasing of pump mass throughput when the spinning speed is constant ; the cross air - blow conditions have much effect on the shaped degree ; the scope of shaped cegree is increasing when the aspect ratio of spinneret hole is increasing ; the shaped degree has obvious decreasing tendency in the small zone of spinning path and this decreasing became gently when the pump mass throughput is increasing 模擬的結果表明:扁平纖維的異形度隨著紡絲溫度及特性黏度的升高而降低;泵供量一定時,紡速對異形度的影響不大;紡絲速度一定,異形度隨著泵供量的增大而增大;吹風條件對異形度的影響較大;隨著噴絲孔的長寬比的增大,異形度增加的幅度也較大;異形度在紡程上較小的區間內有明顯的下降趨勢,并隨著泵供量的增加其下降的趨勢變緩。

The spinneret material used in melt spinning , the spinneret shape , the rheological behaviour of the melt in orifice , the spinneret microhole geometric important indexes , the orifice arrange mode , the orifice opened scope and distance , the spinneret thickness were introduced in detail 摘要介紹了熔融紡絲所用噴絲板的材質、噴絲板形狀、熔體在噴絲孔中的流變特征,噴絲板微孔幾何形狀重要參數,噴絲孔排列方式,開孔范圍及孔間距,噴絲板的厚度。

The technologies for the preparation of polymer nanofibers include electrospinning , sea - island model spinning , catalyzed extrusion polymerization , and molecular spinneret spinning etc . electrospinning is the focus way recently and has demonstrated a large potential 高聚物納米纖維的制備技術有電紡絲、海島形雙組分復合紡絲、催化擠出聚合、分子噴絲板紡絲等,其中電紡絲技術是目前研究的熱點,而且具有較大的發展前景。

Part of the electronic apparatus , medical equipment , spare part production and maintenance of the automobile , motorcycle , engine , aeroplane , metal press piese , oil , pump glib , compressor part and spinneret and washing , filtration of core of chemical fibre industry 應用范圍:電子電器零件、醫療器械、汽車、摩托車、機車、飛機零部件的生產與維修,金屬沖壓件、油泵油嘴、壓縮機零件及化纖行業的噴絲板與過濾芯的清洗。

This image then will be recovered and threshold transformed , thickened and rotated . finally system measures the parameters of the micro - hole and outputs the result . the high - automation of the system makes the worker with responsibility for measuring spinneret do much less than before 然后通過去噪、閾值處理、圖像細化、邊緣檢測、圖像旋轉等預處理后,再對微孔的形狀分析和參數測量。

The paper analyzed the features and present state of the measuring system for spinneret , and then applying the technology of digital image processing , we designed a type of new measuring system for spinneret 本文分析了噴絲板檢測系統的特點和現狀,設計了一種應用數字圖像處理技術的噴絲板檢測系統。

It is convenient for you to adjust the warming temperature , if install it far from the spinneret . if you like , you can also install it outdoor 為了方便您洗浴時隨時調節取暖溫度,建議安裝在遠離噴頭的位置,如用戶想安裝在浴室外是完全可以的。

And it ' s high - efficiency high - precision and high - speed make the system competent for measuring the spinneret 系統具有高效、快速、精確的特點,且適用于多種孔型。
