    • The invention provides a method of improving the digestion of wood chips into pulp. The method involves: adding a liphohydrophilic glycerol-based polymer additive to a solution used in the digestion process. This additive is unexpectedly effective at facilitating digestion. The branched and ether structure of the additive allows it to withstand the harsh nature of a highly alkaline environment. In addition, it is more soluble in high pH than other surfactants. The structure, resistance, and particular balance between hydrophobic and hydrophilic regions, causes the additive to increases the interaction between the wood chips and the digestion chemicals. This in turn reduces the costs, the amount of additive needed, and the amount of reject wood chunks that result from the digestion process.
    • 本发明提供了一种改善木屑进入纸浆的消化方法。 该方法涉及:将一种亲水基亲油甘油基聚合物添加剂加入到消化过程中使用的溶液中。 这种添加剂在促进消化方面出人意料地有效。 添加剂的支链和醚结构使其能够承受高碱性环境的苛刻性质。 此外,它比其他表面活性剂更易溶于高pH。 疏水和亲水区域之间的结构,电阻和特殊的平衡导致添加剂增加了木片与消化化学物质之间的相互作用。 这又降低了成本,所需添加剂的量以及消化过程产生的拒收木块的量。
