PWY泡沫检验方法的修正研究及实证分析（英文）
Title:AStudyontheModificationandEmpiricalAnalysisofPWYFoamInspectionMethod
Abstract:
ThePWYfoaminspectionmethodiscommonlyusedtoassessthequalityandperformanceoffoams.However,overtime,limitationsandshortcomingsoftheoriginalmethodhavebeenidentified.ThispaperaimstoaddresstheseissuesbyproposingmodificationstothePWYfoaminspectionmethod.Additionally,anempiricalanalysisisconductedtoevaluatetheeffectivenessoftheproposedmodifications.Thestudyfindingsprovidevaluableinsightsforprofessionalsinthefoamindustry,enablingthemtomakeinformeddecisionsregardingfoamqualityandperformanceassessment.
Introduction:
Foamsarewidelyusedinvariousindustries,includingconstruction,automotive,andpackaging.Thequalityandperformanceoffoamsarecriticalfactorsindeterminingtheirsuitabilityforspecificapplications.ThePWYfoaminspectionmethodhasbeentraditionallyemployedtoassessfoamqualitybasedonitsporosity,waterabsorption,andyieldstrength.However,theoriginalmethodhasitslimitations,suchassubjectivityandlackofprecision.Therefore,thisstudyaimstomodifythePWYfoaminspectionmethodtoovercometheseshortcomings.
