废纸制浆再造纸的障碍—胶黏物,用生物酶、窄缝压力筛、轻质除渣器、热分散搓揉的方法,只能减少大粒度的胶黏物,但不能彻底解决问题。我们在生产实践中总结消除胶黏物得规律为“机械方法筛除、轻重比例分离、有机溶剂软化、无机溶剂氧化,改变胶黏物的性质,生成没有黏性能起浮选剂作用的液体,起浮于浆面与纸浆纤维分离排除。
Waste paper Pulp and paper recycling obstacles - stickies, with biological enzymes, narrow slit pressure screen, light Cleaner, heat dispersion kneading method, can only reduce the size of the stickies, but can not completely solve the problem . We summarize the practice in practice to eliminate sticky was ”mechanical screening, separation of light and heavy, organic solvent softening, inorganic solvent oxidation, change the nature of the sticky, non-sticky flotation agent to generate the role of the liquid , From floating in pulp surface and pulp fiber separation and exclusion.
