靜電紡絲—循環熱壓法製備PVDF膜之多態結晶相分析
為了解決Air viscosity 的問題,作者蘇柏諺 這樣論述:
本研究先將聚偏二氟乙烯(PVDF)以靜電紡絲之製程產生一定量的β相,然後再使用循環熱壓的方式來探討其對於PVDF生成β相之影響及三相(α、β、γ)的相變化與熱穩定性。其中的重點在於循環熱壓法可否影響靜電紡絲PVDF的極性相(β、γ)之生成。本研究分成兩部分,第一部分先利用機械壓縮的方式來探討在何種壓力(50 ~ 500 MPa)的條件下最有利於靜電紡絲PVDF中極性相的生成;第二部分則沿用第一部分的最佳壓力(300 MPa)來對靜電紡絲PVDF進行循環熱壓的實驗。試片表面形貌由SEM觀察,而DSC與FTIR可以分別計算總結晶度(Xc)與個別的相含量(F(α)、F(β)、F(γ)),且總結晶度
與相含量相乘可得到單相結晶度(Xα、Xβ、Xγ)最後在使用XRD來推估試片的應變與晶粒大小。首先,第一部分中以機械壓力對電紡PVDF進行壓縮,由FTIR的計算結果發現在壓力為300MPa的條件下PVDF的F(β)由原本電紡的56.22 %上升到最高值66.94 %,因此後續循環熱壓便全部在壓力為300 MPa的固定壓力下進行。第二部分實驗中的SEM圖表現出在熱壓溫度大於100 oC時,試片會有較低的孔隙率。但是因為電紡PVDF初始孔隙較多,因此有機會出現空氣團聚而形成孔洞。從DSC計算的結晶性中可以發現所有試片均在熱壓溫度為140 oC時有最高的結晶性,表示PVDF在此溫度最容易生成穩定的結晶
型態,其中最高結晶度為試140 oC熱壓1循環(140-1)的58.74 %。此外,在FTIR中我們不只單純計算出各相的含量,我們必須將DSC計算的結晶度(Xc)與各別相含量(F(α)、F(β)及F(γ))相乘,從而得到真正的單相結晶度(Xα、Xβ及Xγ),以便更好觀察循環熱壓法對於電紡PVDF的影響。而其中試片160-1有最高的Xβ = 43.7 %,試片140-1有最高的Xα = 15.4 %以及第二高的Xβ = 43.3 %。另外,在熱壓溫度低於165 oC時Xβ會隨熱壓溫度增加而增加。由此可知在140 oC ~ 165 oC時我們可以此為基礎來增加更多的β相結晶度。然而,本研究中的循環
熱壓法的Xβ與Xc會隨著熱壓的循環次數增加而急遽減少,就像是在4循環實驗中熱壓溫度高於140 oC時的各相結晶性皆不超過15 %,在8循環中更是不超過10 %。在DSC與FTIR的資料整合中,我們還可以整理出在電紡PVDF的熱壓製程後對各相熱穩定性的影響。從試片165-2與170-2的DSC圖中可以發現γ相的吸熱峰值最低點為172.69 oC,也是本研究中發現的γ相存在的最低熔點。另外,在試片165-8中觀察到兩個吸熱峰(174.87 oC及176.37 oC),再加上此試片中的β相結晶度大於α相結晶度,推斷β相在此條件下的熱穩定性是大於α相的,所以174.87 oC為β相的最高熔點。再由XR
D的分析結果中我們得知α相的應變一直高於β相,並且隨著循環次數增加而略為增加,符合文獻資料中提到的β相可以由受應力影響的α相變化而來。雖然電紡PVDF的結晶度會隨熱壓溫度及循環次數增加而降低,而由Scherrer’s 方程式估算的晶粒大小中顯示各相的平均晶粒大小會隨著熱壓的溫度及循環次數提高而增加。綜上所述,相較於原始的電紡纖維膜,循環熱壓製程可以有效增加試片的密度以及降低試片的缺陷。當熱壓溫度低於或等於140 oC時,熱壓循環次數的增加亦同時增加Xc與Xβ;而當熱壓溫度高於140 oC時會增加高分子鏈的活動性從而使Xc與Xβ呈現相反的趨勢。在140 oC及160 oC的1循環熱壓條件下可得到
最佳的Xβ為43.5 %,因為此溫度最接近PVDF的再結晶溫度。為獲得大晶粒與高結晶度的β相,熱壓溫度應該要低於 165 oC且低於4次循環;而大晶粒與高結晶度的γ相熱壓溫度則是要大於160 oC且循環約2 ~ 4次。
Practical Atlas for Bacterial Identification
![](/images/books_new/F01/573/30/F015730408.webp)
為了解決Air viscosity 的問題,作者Cullimore, D. Roy 這樣論述:
Published nearly ten years ago, the first edition of Practical Atlas for Bacterial Identification broke new ground with the wealth of detail and breadth of information it provided. The second edition is poised to do the same. Differing fundamentally from the first edition, this book begins by introd
ucing the concept of bacteria community intelligence as reflected in corrosion, plugging, and shifts in the quality parameters in the product whether it be water, gas, oil, or even air. It presents a new classification system for bacterial communities based upon their effect and activities, and not
their composition.The book represents a radical departure from the classical reductionist identification of bacteria dominated by genetic and biochemical analyses of separated strains. The author takes a holistic approach based on form, function, and habitat of communities (consorms) of bacteria in
real environments. He uses factors related to the oxidation-reduction potential at the site where the consorm is active and the viscosity of the bound water within that consorm to position their community structures within a two-dimensional bacteriological positioning system (BPS) that then allows t
he functional role to be defined. This book has an overarching ability to define bacterial activities as consorms in a very effective and applied manner useful to an applied audience involved in bacterial challenges.Organized for ease of use, the book allows readers to start with the symptom, uncove
r the bacterial activities, and then indentify the communities distinctly enough to allow management and control practices that minimize the damage. The broad spectrum approach, new to this edition, lumps compatible bacteria together into a relatively harmonious consortia that share a common primary
purpose. It gives a big picture view of the role of bacteria not as single strains but collectively as communities and uses this information to provide key answe Roy Cullimore has a PhD in Agricultural Microbiology and went on to develop a number of patents, edited a series of books for CRC Press
on Sustainable Water Wells, and has published in the area of applied microbial ecology. Cullimore was involved in deep-ocean research and presently has seven experiments on the RMS Titanic together with experiments on other ship wrecks to determine the rates of decay.
二段式真空產生器之參數分析與優化應用
為了解決Air viscosity 的問題,作者陳品勳 這樣論述:
噴射真空產生器因體積小且產生真空方便之特性,在搬運精密及不規則形狀之物品具有優勢,故於自動化生產之應用十分廣泛。本數值研究模擬分析二段式真空產生器之流場及性能參數,包括吸入量、消耗量、真空度以及第二段最高真空度;並執行系統化之參數分析工作,包括主噴嘴、連接管、與混合排氣管之幾何參數對其性能之影響。最後整理參數分析之結果,並據以設計出兩款優化真空產生器,其中一款是以性能為目標的優化模型,另一為符合實際性能需求之最短長度真空產生器,可使其降低成本且安置更加彈性。經由數值計算與參數分析之結果顯示,原始二段式真空產生器之長度為55.5mm,達到真空度-90KPa之供給壓力為0.43MPa,此壓力下之
吸入量為45.2L/min、能源效率為20.1%,至於真空度峰值-94.2KPa則須供給壓力0.55MPa。而本文之最小體積模型之長度僅有35.5mm,於各壓力下之性能與原始模型相近,而其能源效率為20.6%;另外,此模型在供給壓力0.45MPa即可達到真空度峰值,這表示最小體積模型在運作更節省能源,且具有方便安置與成本優勢。至於另一款性能優化模型之長度為54.5mm,此模型在各壓力下所有性能皆優於原始模型,特別是在供給壓力0.4MPa時,此優化模型就已達到真空度-90KPa,且所產生之吸入量為49.0 L/min、能源效率為24.8%,明顯地較原始真空產生器高出許多;這代表性能優化模型除具有
節省能源之優勢外,還能更快地達到所需之真空度並提供更多的吸入量。綜合歸納來說,本研究建立一套系統化的設計流程,也取得各重要參數對真空產生器性能之影響,並藉此成果規劃出兩款優化模型,以滿足特定需求之二段式真空產生器的應用。
