EFFECT OF TEMPERATURE, HEATING RATE AND HOLDING TIME ON THE PROPERTIES OF CARBON WEB MADE FROM ACRYLIC WASTE

Popis výsledku v původním jazyce

In this study carbon webs are prepared through controlled pyrolysis of web from acrylic waste usingphysical activation in high temperature furnace. The objective is to analyze the effect of three factors (effect of final temperature, holding time after carbonization and heating rate) on physicalcharacteristics of carbon web. The effect of these factors on the yield (%), shrinkage, flexibility, surfacearea and electrical conductivity have been analyzed. The yield of carbon web decreases by increasingtemperature, heating rate and holding time due to more decomposition of PAN. The surface area ofcarbon web is found to be maximum at optimum values of heating rate , highertemperature with no holding time. Higher heating rate causes sudden release of volatile matter, whichis not good for getting good results. The electrical conductivity is found to increase with increase of holding time, temperature and reduces with increasing of heating rate. Athigh temperature the basal planes in the carbon becomes more parallel oriented, hence electricalconductivity increases at high temperature.
