METHOD OF CONTINUOUS PREPARATION OF RECLAIMED RUBBER USING MULTI-STAGE SCREW EXTRUDERS

The invention relates to a method of preparing reclaimed rubber, especially using multi-stage screw extruders, which belongs to the field of recycling and reusing of waste rubber. The rubber powder and softener which were preliminarily mixed are compacted and added into first counter rotating twin screw extruder through thermal insulation and metering apparatus, the softener permeates the waste rubber powder uniformly under the action of temperature in the extruder to finish primary desulfurization of rubber waste powder; add preliminary devulcanized material continuously into second multi screw extruder after cooling by transformation device, rapid desulfurization and regeneration can be achieved by means of activator and shear action; The desulfurized rubber powder is cooled and transported into the third multi-screw extruder in series, the performance of deprocessing can be improved by shear action under low temperature; After extrusion, the recycled rubber is obtained by molding device and cooling device. The whole process is completed under closed oxygen isolation condition, realizing safe, simple and continuous desulfurization regeneration. It is energy saving and environmental protection with excellent properties.

Plastic articles made from the segregation, decontamination, and purification of biomedical waste plastics in a system leveraging waste production data to modify material purification and product manufacturing

A process for the segregation, sterilization, and purification of recycled plastic medical waste with the subsequent production of plastic products made therefrom is disclosed. Also disclosed is a method for the front-end segregation of recycled plastic medical waste into a polypropylene waste stream and a mixed plastic waste stream. These segregated streams are further purified through a processing method that removes contaminating fibrous, metal and other waste products. Polypropylene and mixed plastic streams isolated using these methods yield a homogenous material that can be blended with other materials for the production of raw plastic or for extrusion to form commercial plastic products. A method for tracking regulated and non-regulated medical waste stream production kinetics and chain of custody from discrete waste disposal sites is also disclosed.
