METHOD AND APPARATUS FOR REUSING FLUOROPLASTIC WASTE AND PRODUCING FINE POWDER Russian patent published in 1999 - IPC

Abstract RU 2133196 C1

FIELD: polymer production. SUBSTANCE: apparatus is preliminarily pumped through with dry nitrogen and then filled with equal portions of waste. Batch melt is heated in reactor and hot fluoroplastic destruction products are cooled by gas carrier and displaced into tube. Products are deposited on walls and in cooler and further are collected in receivers in the form of powder material, which is are packed. Remaining destruction material having been separated from powder product is loaded into afterburner, from which, resulting product is discharged through discharge port for further processing. EFFECT: increased degree of dispersity of product. 5 cl, 1 dwg
