pH值对脱墨浆灰分保留和浮选效果的影响

废纸脱墨制浆生产线在生产出优质浆料的同时，应尽量地提高废纸制浆得率。广纸九号机配套的脱墨生产线中，对生产线进行良好的控制，提高浆料中灰分保留率，而又不影响浮选脱墨效果，让生产线稳定高效的运行，生产出符合纸机抄造的优质浆料。PH值作为脱墨制浆系统控制的一个重要的参数，其变化对脱墨生产过程有着很大的影响。

The effects of pH on ash retention and flotation in DIP process

Several key points about the losses of ash in the process of deinking pulp were introduced in this paper. The methods of increasing ash content under the condition of no influence on the flotation effect were discussed. The key work is to find the optimal pH in flotation to achieve the target of increasing ash content in pulp as well as stable and efficient production.
