This article designed two kind of resources recyclings to abandon the line board foundation plate the plan: One: Will abandon the glass fiber resin powder direct mould pressing through the increase epoxy resin and the firming agent which the line board foundation plate smashing obtained will arrive to take shape, takes shape the product to be allowed to take the building materials sale; Hundred million uses the solvent extraction from to abandon in the glass fiber resin powder to recycle the purer glass fiber, these purer glass fiber may take the enhancement material or the building materials padding sale. These two kind of plans merit is: The process load big, the recycling cost low, the craft simple, the market prospect is broad .
The experiment draws the conclusion: The synthesis considered the recycling cost and the product performance, obtain best takes shape the condition is: The solidification suppresses epoxy resin =1:1, abandons the glass fiber epoxy resin/solidification to suppress 10:1:1, warm 45 ℃, heats up time 3h .
The temperature 75 ℃, heats up time 22h, nitric acid solution thick 8mol/l, the ratio is abandons glass fiber nitric acid volume =15g:100ml the decomposition condition to be suitable .
