Determining the effective parameters in performing polymeric activities in extruder

Using extruder as batch reactors, for processes such as polymerization, polymer adjustmentor polymeric alloy adaptation is among the technologies which are getting more favorable day to dayand they can challenge traditional ways through their economical efficiency. In the present paper,technical advantages, disadvantages and characteristics of reactor extruder and the state of flowmechanism performance in extruder have been investigated and studied, and the effective parameters onthe process condition have been surveyed. The results indicate that the extruder is appropriate forreactor processes because of its capability in performing the processes step by step, supreme transmitand distributing integration, and temperature controllability. The investigations also indicate thateffective parameters on performing proximate polymeric processes in reactor extruders include tarriancetime, distribution state, and rate and type of energy, that it is required to be informed about thecharacteristics and nature of process and needed and special equipments to perform it, before choosingthese instruments for extruder activities, besides, it is required to consider effective parameters such astarriance time, extruder volume, variants and specification of the starter type in choosing extrusionprocess in order to improve the product quality by controlling these parameterMost results areaccording to investigation on existence extruder in Polypropylene Company, model ZSK 320 duringproducing varicose grades.
