Visualizing curing process inside polymers

Applied Physics Letters, 2020
The curing process of polymer materials and structures has a crucial influence on their final properties. However, existing methods are only capable of characterizing their time-resolved information. To comprehensively reveal curing behaviors inside polymers, we report a method that combines optical coherence tomography and quantitative phase imaging ...

Evolution of temperature stress and tensile properties of concrete during steam-curing process

Construction and Building Materials, 2021
Nowadays, steam curing is widely used in the production of prefabricated components. However, studies have shown that steam curing can lead to micro or macro-cracks in concrete caused by the curing regime which can affect the performance of the concrete ...

Monitoring the curing process of epoxy adhesive using ultrasound and Lamb wave dispersion curves

, 2021
Monitoring the stiffness of adhesives is a crucial issue when considering the durability and strength of adhesive joints. While there are many studies conducted on specimens made only from adhesive, the problem of curing of an adhesive film in real ...

Effect of microwave-assisted curing process on strength development and curing duration of cellular lightweight geopolymer mortar

, 2021
The heat curing process using an electric oven has been generally applied for curing geopolymer material as it accelerates strength development. However, a microwave curing process is an alternative approach to obtain a shorter heat curing process.

Cured colour development during sausage processing

Meat Science, 1996
A study of colour evolution in dry cured sausage manufactured using industrial technology was made. Parameters which define changes related to nitrosation during curing were determined. The main changes in the colour characteristics of Spanish sausage took place during the fermentation stage.

Heat Curing Processes

2020
Molding sand hardening in these technologies occurs as a result of warming of sand and resin mixture, or more often by contact of this mixture with warmed pattern system. All processes of this type assure good dimensional accuracy, provided that good-quality patterns (metal), which can be very expensive, are used.
