The TBA value of all treatments increased gradually up to the end of the storage time

A similar experiment was performed with THC,this time only evaluating the FBBB stability at refrigerated temperatures.The characteristic red color indicative of the presence of THC did form; however,like the hemp,the color was duller than when performing the usual procedure.Finally,FBBB was preloaded onto PSPME substrates and left in refrigerated temperatures for a week and were then […]

It confirms that there was indeed a direct effect of hemp fabric on the Izod impact energy of the composites

Considering the average lengths before and after extrusion-injection molding , a reduction of about 2 times in the case of HF, 2.5 times for HF and 4 times for HF was observed. It follows that the reduction of fiber length was greater for longer initial fibers, similar to the results on simple PP/HF composites. Moreover, their […]

The values of initial adsorption rate and desorption constant varied in function of the copper concentration

Values of ki and correlation coefficients are listed in Table 3,from which it can be seen that the kinetics of copper adsorption on the SHI-W and SHI-C samples followed this model with R2 values higher than 0.95,indicating that intraparticle diffusion was involved in the adsorption process.For these samples,it seems that physisorption played the main role in […]

Selection for genetically stable cultivars with larger seeds will be important for increasing hemp grain yields

The gel point was taken as the time when the sol did not show any movement on turning the container upside down.For analysis of the binder,the left-over sol contaminated with leached out hemp shiv extractives was aged in a container until the gel point was reached and the specimen was termed the “binding matrix”.A schematic illustration […]
