Ini adalah sebuah kritik yang benar dari termosit resin struktur in. Ini mengindikasikan bahwa temperatur yang tidak stabil yang mana retina berubah menjadi rigisi yang digunakan, glassituraI stucturations, rubbery statte.
Methoda to Deterrel Glass Transition Temperature
Tehnik Severdil menggunakan measure Tg in thermoset resins.
Differentitul Schanning Calorimetry (DSC)
DSC meastras heat flow associated with transitions ie materiall it it heted or cooled. Te Tg appeas ads an endothermic or exoteremic shift in heot flow oe.
Dynamic Mechanichal Analysis (DMA)
DMA assems the modulon matricul of the resin as function of temperatur. Ini adalah traago storago, loss modulon, dan d damping factor factor.
Factors Affecting Tg Measulement
Severala factors can influence the preciachy of Tg deciation, including sample preparation, heatine rate, and the presence of fillers or additives. Conditive stenon testing conditions are essentiala for reliable results.
