腰果酚聚氧乙烯醚复配脱墨剂的制备及应用
Preparation and Application of Cardanol Polyoxyethylene Ether Compounded Deinking Agent
摘要
Abstract
Cardanol polyoxyethylene ether( CPE) was prepared from natural cardanol and characterized by FT-IR and 1 H NMR. By combining with other commercially available surfactants ( fatty alcohol polyoxyethylene ether ( AEO-9 ) , fatty alcohol polyoxyethylene ether sulfate ( AES ) , sodium dodecyl sulfate ( K12 ) , Tween-60 and Tween-80 ) , CPE was used as flotation deinking agent of mixed office waste paper. The experimental results showed that CPE was effective and compatible, which could achieve better effect when mixed with a variety of surfactants. The deinking effect of CPE compounded with other two surfactants was better than that of double components and CPE alone. Results showed that the blend of three surfactants, composed of CPE:AES:AEO-9 with mass ratio of 1:1:1, could provide best effect, and the brightness of the recycled paper product reached to 90. 45% ( ISO) , ink removal efficiency was 91. 96% and pulp yield reached to 75. 7% .关键词
