【摘要】：本研究采用摩擦電選法回收廢棄線路板中的有機組分,主要探究了廢棄線路板非金屬組分的摩擦荷電特性,以及在最優(yōu)分選參數(shù)條件下進行靜電分選的效果。不同組分荷質比的測量結果顯示,PMMA作為摩擦材料使廢棄線路板非金屬組分中的有機物與無機物荷電性質相反,荷質比差異較大,說明PMMA作為摩擦材料時廢棄線路板非金屬組分中的有機物與無機物可實現(xiàn)摩擦靜電分選。分選結果表明靠近兩極位置的收集槽中產品的產率較高,分別為27.22%和51.71%,靠近正極收集槽中產物有機組分的燒失量達到了81.42%。該研究證明了摩擦電選回收廢棄線路板中有機組分的可行性,為廢棄線路板有價組分的回收和再利用提供了一種有效的途徑。
[Abstract]:In this study, friction electrolysis was used to recover the organic components from the waste circuit board. The friction charge characteristics of the non-metallic components of the waste circuit board and the effect of electrostatic separation under the optimal separation parameters were investigated. The results of the measurement of the charge / mass ratio of different components show that PMMA is used as friction material to make the charge properties of organic compounds in non-metallic components of waste circuit boards contrary to those of inorganic materials, and the charge / mass ratio is quite different. The results show that PMMA can be used as friction material to separate organic and inorganic compounds from non-metallic components of waste circuit board. The separation results showed that the yield of the product in the collection tank near the two poles was 27.22% and 51.71%, respectively, and the burning loss of the organic components of the product near the positive electrode collecting tank reached 81.42%. This study proves the feasibility of triboelectric separation and recovery of the components in the waste circuit board, and provides an effective way for the recovery and reuse of the valuable components of the waste circuit board.
