Cure Kinetics of Epoxy Resin/MP/Anhydride/Accelerant Flame Retardant Composite

Before we start, I like to mention my latest discovery on the internet – chemical slot games. I stumbled on them on accident while researching something and I was so impressed and entertained after playing them for a couple of hours that I had to share it with you. Just visit this site to get a free no deposit bonus and play them without risking money. And now let’s talk about Cure Kinetics.

Abstract Cure kinetics of epoxy resin E51/MP/methyltetrahydrophthalic anhydride (MeTHPA)/ 2-ethyl-4-methyl-imidazole (2,4-EMI) flame retardant composite were studied using the dynamical tortional vibration method. The influence of MP loadings on The cure showed has improved studied were well. The results showed that the rate of cure reactions depended distinctly on the cure temperature. At low MP loadings, the gelation time t g for the systems did Not change obviously while at higher MP loading (higher than 20 phr) t g had a remarkable increase. further, the Flory ‘s gelation theory and Avrami equation could be used to describe the cure behavior of epoxy composite system…

Determination of resorcinol on glassy carbon electrode modified by carbon nanotube and its application in wastewater analysis

Abstract about interesting chemistry news articles for adsorptive stripping method for the determination of resorcinol on multi-walled carbon nanotube modified glassy carbon electrode (MWNT-GCE) was developed. Cyclic voltammetry was used in the study of the electrochemical behavior of resorcinol on MWNT-GCE. The sharp peak of resorcinol appeared at 0.6 V (vs. Ag/AgCl) with the differential …

Determination of Tanshinone IIA in two kinds of Chinese traditional patent medicines by HPLC

Abstract A HPLC method for the determination of Tanshinone IIA in the Dan Qi Pian and Tong Mai Chongji was established. The sample was dissolved in methanol and extracted by ultrasound, then chromatographed on LUNA-C18 column with mobile phase of methanol-water (84:16). The flow rate was set at 0.8mL/min and the detection wavelenghth was of …
