determining the effective parameters in performing polymeric activities in extruder

using extruder as batch reactors, for processes such as polymerization, polymer adjustment or polymeric alloy adaptation is among the technologies which are getting more favorable day to day and 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 flow mechanism performance in extruder have been investigated and studied, and the effective parameters on the process condition have been surveyed. the results indicate that the extruder is appropriate for reactor processes because of its capability in performing the processes step by step, supreme transmit and distributing integration, and temperature controllability. the investigations also indicate that effective parameters on performing proximate polymeric processes in reactor extruders include tarriance time, distribution state, and rate and type of energy, that it is required to be informed about the characteristics and nature of process and needed and special equipments to perform it, before choosing these instruments for extruder activities, besides, it is required to consider effective parameters such as tarriance time, extruder volume, variants and specification of the starter type in choosing extrusion process in order to improve the product quality by controlling these parametermost results are according to investigation on existence extruder in polypropylene company, model zsk 320 during producing varicose grades.
