发明名称 A method for manufacturing paper with a constant filler content
摘要 A method of controlling the production of filler-containing paper. Filler and retention agent are delivered to a paper manufacturing system in a process of paper manufacture. The amount of filler in the paper is measured, as is also the filler concentration or the total concentration in the white water or the stock. Filler is delivered such that the system will be buffered with filler to a generally pre-determined concentration level. The continual addition of retention agent is based exclusively on the amount of filler in the paper measured at that moment in time. When the measured amount of filler present is lower than a desired level, the addition is increased. When the measured amount of filler present is higher than a desired level, the addition is reduced. The continual addition of filler is based, exclusively on the concentration level of filler measured in the white water or the stock.
