This article introduces the use ofDifferential scanning calorimetrylaw(DSC)applicationDSC determination of crosslinking degree of EVA that has been crosslinked during the lamination process of photovoltaic modules.

Differential scanning calorimetryThe method is to measure temperature under the programThe relationship between measuring the heat flux value of an object and temperature variation. AvailableYuIn the research and development, performance testing, and quality control of materials，Characteristics of materials , such as glass transition temperature, cold crystallization, phase transition, melting, crystallization, product stability, solidification/Crosslinking, oxidation induction period, etc.EVAIn 120℃to230℃betweenTimely releaselifeSolidification reaction.this method 利用EVAMeasure the curing degree of crosslinked and uncrosslinked samples differentlyEVA cross-linking degree
