Experimental Study on The Recycling Technology of Waste Thermosetting Phenolic Resin Based on Mechanical and Physical Method

Propose a recycling technology of waste thermosetting phenolic resin based on mechanical and physical method,use the range and variance analysis of orthogonal test of four factors at three different levels, obtain the affection of speed,time, feeding material weight,feeding particle size on degradation efficiency of thermosetting phenolic resin. According to the affection,the influencing factors could be arranged as follows : speed>feeding particle size> time>feeding material weight,and optimal technology parameters are determined as follows: speed is 3000 r / min, time is 90 min, feeding material weight is 50 g, feeding particle size is 0.425 mm.
