Abstract: A treatment method for EVA waste materials includes the following steps: step 1: crushing waste EVA shoe soles, waste EVA sheets, and waste EVA trimmings to obtain block-shaped crushed materials with a length of less than 7 cm and a width of less than 5 cm; then, putting the block-shaped crushed materials into a waste crusher to obtain strip-shaped crushed materials; step 2: putting the strip-shaped crushed materials obtained in step 1, Surlyn resin, and PMP into an internal mixer in a weight ratio of 85:(4-10):(4-8), wherein an internal mixing temperature gradually rises, a highest temperature of the internal mixing temperature is 150° C., and an internal mixing time is 18 to 25 minutes, so as to obtain block-shaped mixed materials; and step 3: processing the block-shaped mixed materials, which have been subjected to internal mixing by a screw extruder and an open mill to obtain an EVA recycled film.

Abstract: Various embodiments of the present technology generally relate to systems, tools, and processes for change control systems. More specifically, some embodiments relate to machine learning-based systems, methods, and computer-readable storage media for job approvals, logging, and validation of critical functions and tasks based on compliance requirements, threat models, intended outcomes, rules, regulations, and similar restrictions or combinations thereof. Job approvals, rejections, and deferrals may be combined with machine learning techniques to conduct behavioral analysis in some implementations. The system disclosed herein provides for an improvement over existing change control methods requiring manual and time-consuming analysis.
