Enhancing Thermal Efficiency and Temperature Uniformity of Barrel Using Induction Heating
No full text[[abstract]]在塑膠射出成型過程中，熔膠品質與穩定性是影響塑膠成品品質重要的因素之一，熔膠品質穩定性取決於料管持溫階段的內表面溫度穩定性以及整體溫度均勻性表現，現今射出成型機料管主要加熱方式為傳統電阻式電熱片加熱，隨著時代演進需要更高的加熱效能及更加節能的方法。感應加熱有著相當快的加熱速度及能源使用效率等優點，但是較差的感應線圈設計會導致磁場間的相互干擾現象，使溫度均勻性下降更可能導致熱效率降低，所以感應線圈設計也相當重要。本研究首先使用COMSOL模擬軟體分析感應線圈的纏繞方式對溫度均勻性影響，以及改善磁場間干擾現象等，並經由各種感應線圈優化設計找出最佳感應線圈纏繞方式或料管外形設計，最後實際製作出感應線圈與料管進行實驗以驗證模擬的結果，並比較感應加熱與傳統電阻式加熱熱效率與均溫性。由模擬結果顯示，料管外形設計為螺旋式時，不論電流方向皆有約98%的溫度均勻性與80%的熱效率，是所有設計型式中最佳結果，且可有效解決因鄰近效應所產生的磁場干擾問題；單段料管加熱實驗顯示，電阻式加熱加熱段熱效率為51%感應加熱為86%，電阻式加熱持溫段熱效率為10%感應加熱為23%，電阻式持溫段均溫性為79%感應加熱為68%；雙段料管加熱實驗結果顯示，電阻式加熱加熱段熱效率為58%感應加熱為69%，電阻式加熱持溫段熱效率為3.9%感應加熱為5.4%，電阻式持溫段均溫性為92%感應加熱為93%。模擬與實驗結果證實使用感應加熱以及優化料管外形設計可以有效提升熱效率與溫度均勻性。[[abstract]]Intheinjectionmolding,themeltqualityandstabilityarebothimportantfactorsthatdirectlyaffectthemoldingquality.Themeltqualityisdependingonthestabilityanduniformityofbarreltemperature.Thetraditionalinjectionmachineusestheresistanceheatingtoperformthebarrelheatingprocess,buttheresistanceheatinghavingaproblemofslowheatingandlowenergyefficiency.Inrecentyears,usingtheinductionheatingtechnologyinbarrelheatinghasbeenmentioninsomeresearch.Fastheatingrateandenergyefficiencyarebothadvantagesofinductionheating.However,poordesignofinductioncoilcauseseriousmagneticfieldinterference.Therefore,howtodesignasuitableinductioncoilisthemostimportantchallengeforthebarrelinductionheating.Inthisstudy,bothofthesimulationandexperimentalmethodwereperformedtoanalyzethemagneticfieldandtemperaturedistributionunderdifferencebarrelshapeandcoildesign.Thesimulationresultsshowthebarrelwithgrooveshasbetterheatingrateandtemperatureuniformity,andcaneffectivelysolvethemagneticfieldinterferencebytheproximityeffect.Single-sectionbarrelheatingexperimentsshowthat,theheatingsectionthermalefficiencyofresistiveheatingis51%andinductionheatingis86%,theholdingsectionthermalefficiencyofresistiveheatingis10%andinductionheatingis23%,andtheholdingsectiontemperatureuniformityofresistiveheatingis79%andinductionheatingis68%.Double-sectionbarrelheatingexperimentsshowthat,theheatingsectionthermalefficiencyofresistiveheatingis58%andinductionheatingis69%,theholdingsectionthermalefficiencyofresistiveheatingis3.9%andinductionheatingis5.4%,andtheholdingsectiontemperatureuniformityofresistiveheatingis92%andinductionheatingis93%.Simulationandexperimentalresultsconfirmedthattheusinginductionheatingandoptimizethebarrelshapedesigncaneffectivelyenhancethethermalefficiencyandtemperatureuniformity
Assessment of children’s exposure to phthalate esters in house dust
No full text[[abstract]]鄰苯二甲酸酯類(Phthalateesters,PAEs)為使用最普遍之塑化劑，主要添加於聚氯乙烯(PVC)塑膠中。PAEs用於許多室內外產品，目前已廣泛流布於室內外環境中，其可能造成不良健康效應亦不容勿視。目前國內對鄰苯二甲酸酯於居家室內環境之研究有限，許多相關議題均值得加以深入探討。本研究主要針對居家為研究場址進行採樣分析，探討居家環境中灰塵中鄰苯二甲酸酯類濃度，再利用灰塵中鄰苯二甲酸酯類濃度計算鄰苯二甲酸酯類暴露量，並與國內PAEs每人每日耐受量(TDI)進行比較。研究結果顯示：在同一居家室內外PAEs濃度比較，發現灰塵中室內PAEs濃度明顯高於室外PAEs濃度。室內以DEHP濃度最高，DEHP濃度範圍為218.98~5308.50μg/g，中位數濃度877.32μg/g；其次為DNOP濃度範圍為70.92~1395.84μg/g，中位數濃度168.60μg/g；室外以DEHP濃度最高，DEHP濃度範圍為47.65~1378.55μg/g，中位數濃度143.70μg/g，其次為DNOP濃度範圍為12.52~649.66μg/g，中位數濃度20.10μg/g。其原因推估為居家室內木質家具、塑膠類製品、地毯、電腦、電源線、巧拼地板等及打掃頻率有關，都會導致PAEs吸附及累積。暴露評估計算結果，兒童一天暴露於PAEs之暴露量，以DEHP暴露量為最高，次高為DINP，BBP暴露量為最低，均低於國內TDI值。[[abstract]]Phthalateesters(PAEs)areusedmainlyasplasticizersinthemanufactureofpolyvinylchloride(PVC)plasticproduct.PAEsareubiquitousandwidelydistributedthroughouttheindoorandoutdoorenvironments.HealthissuescausedbychildrenexposuretoPAEsshouldbeaconcern.ThemajorgoalsofthecurrentstudyweretoinvestigateandconcentrationofPAEsinindoordustfromresidenceenvironmentinTaiwanandtoassesschildren'sexposureandhealthrisktothesePAEs.TheresultsshowedthatthedustPAEslevelsindoorswerehigherthanthatforoutdoorsatsameresidence.TheindoordustDEHPandDNOPlevelswererangedfrom218.98-5308.50μg/g(median:877.32μg/g)and70.92-1395.84μg/g(median:168.60μg/g),respectively.TheoutdoordustDEHPandDNOPlevelswererangedfrom47.65-1378.55μg/g(median:143.70μg/g)and12.52-649.66μg/g(median:20.10μg/g),respectively.TheresultsshowedthatexposurestodustPAEsintheresidenceenvironmentsdidnotexceedthetolerabledailyintake(TDI)setbytheTaiwan
