Abstract: The present invention discloses an in-line production method for providing a retention agent into a liquid flow of a stock suspension and into the short circulation of a paper making machine, wherein the method comprises the steps of: (i) providing a liquid flow of a stock suspension; and (ii) feeding at least one additive into said liquid flow of the stock suspension, wherein said retention agent is formed directly in said stock suspension. The at least one additive may be added to the stock suspension e.g. as a liquid flow. The retention agent provided by the method of the invention may further improve the control of the dewatering rate and subsequently the strength properties of the paper. By this method there is provided a way of forming a retention agent directly into the stock suspension. The need of transporting, e.g. a readymade solution of a retention agent is thereby abolished, and thus the retention aid may be formed in a very cost-efficient way. Further as the retention agent is formed directly into the stock suspension it may very quickly and efficiently adhere to the fine particles, or the filler in the stock suspension and thus a more efficient effect may be achieved.
Abstract translation: 本发明公开了一种在制浆机的液体流中提供保留剂并进入造纸机的短循环的在线生产方法，其中所述方法包括以下步骤：（i）提供液体流 股票暂停; 和（ii）将至少一种添加剂进料到原料悬浮液的液体流中，其中所述保留剂直接形成在所述原料悬浮液中。 可以将至少一种添加剂加入到原料悬浮液中。 作为液体流动。 通过本发明的方法提供的保留剂可以进一步改善脱水速率的控制以及随后的纸的强度性能。 通过该方法，提供了将保留剂直接形成到浆料悬浮液中的方法。 运输的需要，例如 由此可以消除保留剂的现成溶液，从而可以非常成本有效地形成助留剂。 此外，由于保留剂直接形成在原料悬浮液中，因此可以非常快速且有效地粘附到细颗粒或浆料悬浮液中的填料，从而可以实现更有效的效果。
