摘要： The invention provides methods and compositions for enhancing the digestion of pulp in a chemical pulping process. The method uses ultra-low, economically feasible dosages of BH applied right before the pulping process begins, in a stable alkaline solution fed into white liquor line, to improve the process by saving pulping chemicals, increasing pulp brightness and yield and reducing the kappa number.

摘要： Methods to enhance the brightness and brightness stability of paper and paperboard made with Mechanical Pulp are described and claimed. The method involves applying a Penetrant Compound to paper or paperboard in an amount from about 0.001 percent to about 1 percent by weight. The Penetrant Compound can have one component that is either polyamino polyether methylene phosphonate (PAPEMP) and alpha-glucoheptonic-gamma-lactone (GL); or the Penetrant Compound can have two components, where the first component is selected from the group consisting of PAPEMP and GL and the second component is an inorganic salt; or the Penetrant Compound can have three components where one component is selected from the group consisting of PAPEMP and GL, the second component is selected from the group consisting of 3,5-dimethylperhydrothiadiazine-2-thion and dialkyldithiocarbamates and the third component is an inorganic salt.

摘要： A method and apparatus for measuring the deposit forming propensity of a continuously flowing fluid having a bulk pH of about 1 to about 12 comprising measuring the rate at which deposit forms on a quartz crystal microbalance having a top side comprising a working electrode in contact with the fluid and a bottom side isolated from the fluid, wherein the pH of the fluid proximate to the microbalance is controlled electrochemically at about 1 to about 14 by applying to the working electrode a cathodic current of about -0.001 to about -100 mA/cm 2 or an anodic current of from about 0.001 to about 100 mA/cm 2 and wherein the working electrode is coated with or made of a conductive material on which the rate of hydrogen gas evolution is at least 10 times lower than on a gold cathode in acidic solution.

摘要： This invention provides a composition and method for improving a mechanical pulping process by decreasing freeness and amount of shives, providing energy and chemical savings, and enhancing brightness and mechanical strength of a paper product made from a pulp material in the process. The composition includes formulations, such as surfactants, chelants, hydrotropes, reductive and oxidative pulp modifiers, and pH-controlling chemicals. The method includes selectively introducing these formulations to the pulp material in the mechanical pulping process.

摘要： A challenge in using recycled material in the papermaking process is the presence of hydrophobic organics with adhesive properties commonly known as “stickies.” Hydrophobic agglomerates can result in spots or defects in the final paper product or deposit on papermaking equipment resulting in poor runnability and downtime. Technologies for monitoring and controlling microstickies exist. However, a need exists for a technique to rapidly determine the size and content of macrostickies (diameter>100 microns) in recycled pulp process streams. The present invention is a device and method to perform real-time macrostickies and/or any visible hydrophobic particle analysis in an aqueous medium. Using the present invention, furnish quality can be monitored and treatment performance can be monitored and controlled. The technique is based on fluorescence image analysis to identify and count sticky particles as well as measure their size.
摘要翻译：在造纸过程中使用再生材料的一个挑战是与俗称粘合性能的疏水性有机物的存在下“胶粘物”。可以导致在上造纸设备的最终纸产品或沉积斑点或缺陷中的运行性能差和停机时间所得到的疏水附聚物，监测技术和控制微胶存在。然而，需要一种技术来快速确定矿的大小和在再生纸浆工艺流macrostickies（直径> 100微米）的含量。本发明是一种装置和方法，在wässrige介质来执行实时macrostickies和/或任何可见的疏水性颗粒分析。使用本发明，提供的质量可以被监控和处理的性能可以被监测和控制。该技术是基于荧光图像分析来识别和计数粘性颗粒以及测量它们的大小。
