摘要： Apparatus and process for producing foam formed fibrous web in which the furnish is made up by mixing a thin water slurry of fibers at a consistency in the range of from about 0.5 to about 7 weight percent fibers with sufficient aqueous foam containing a surfactant and having an air content in the range of from about 55 to about 80 percent by volume to form a foamed fiber furnish containing from about 0.1 to about 3 weight percent fibers which is supplied directly to the forming felt or wire of a twin wire papermaking machine, adding makeup surfactant and discarding excess aqueous foam from the process as required to maintain the desired volume of foamed liquid therein.

摘要： A non-woven web of fibrous material is produced using a moving foraminous element in the practice of the foam process. A first foam slurry of air, water, fibers and a surfactant is generated and centrifugally pumped into contact with the moving foraminous element. Substantially fiber-free foam is withdrawn from the foraminous element while forming a non-woven web of fibrous material on the foraminous element, and at least a part of the substantially fiber-free foam is used in the generation of the first foam slurry. Recycling is also typically practiced using a centrifugal pump, and the centrifugal pumps are preferably degassing pumps which remove some of the gas from the foam. By practicing the invention it is possible to produce fibrous webs using the foam process that are more than two meters wide, and at a forming speed of more than about 100 m/min (e.g. about 200-500 m/min).

摘要： Raw material, energy and waste management are arranged in a production plant manufacturing pulp, paper, or board or a combination thereof from recycled fibres which is advantageously placed in the middle of a residential community or in its immediate vicinity. The plant has equipment for the manufacture of pulp and/or paper and/or board as well as equipment for the production of energy for at least the production plant's own needs. The production plant uses as fibre raw material waste paper and/or board generated by the residential community and as the source of energy combustible waste generated by the residential community. Moreover, it utilizes as far as possible waste fractions which are produced as by-products in production processes and which contain raw materials and energy either as raw material or as energy or, alternatively, these fractions are supplied outside the production plant for useful use.

摘要： Water draining device for a paper machine or the like, in particular for a felted press of such a paper machine, including a receiving tank extending at least essentially over the machine width. The receiving tank includes a first chamber that receives arriving water and is under ambient pressure, and a second chamber that is connected to the first chamber and is under vacuum, into which the water collecting in the first chamber is aspirated and from which the water is eventually drained. A water receiving device of improved efficiency is also provided by forming a water receiving device by at least one suction channel projecting into the wedge-shaped area between the upper press roll and the dewatering belt, and extending transverse to the pulp web, which suction channel is connected to a source of reduced pressure.

摘要： A method for eliminating detrimental substances in a process liquid. The process liquid has a first pH and, in addition to said detrimental substances, comprises metal ions and suspended material. Carbon dioxide is added to the process liquid in order to bring the process liquid to a second pH, lower than the first pH. Thereby, the metal ions comprise hydroxide builders, wherein the carbon dioxide (CO2) is added in an amount which causes the second pH to be between 8 and 6.5, so that the carbon dioxide primarily forms bicarbonate ions (HCO3null) having a pH-buffering effect and the metal ions primarily form metal hydroxides. Thereafter, the detrimental substances coagulate or agglomerate with the metal hydroxides and are adhered to the suspended material so that they become inactive. The method is advantageously used in connection with pulp and/or paper making processes.
摘要翻译：一种消除处理液中有害物质的方法。处理液体具有第一pH，并且除了所述有害物质之外，还包含金属离子和悬浮物质。将二氧化碳加入到工艺液体中，以使处理液体达到比第一pH低的第二pH。因此，金属离子包括氢氧化物助洗剂，其中二氧化碳（CO 2）的加入量使第二pH为8至6.5，使得二氧化碳主要形成具有pH值的碳酸氢根离子（HCO 3 - ），缓冲效应和金属离子主要形成金属氢氧化物。此后，有害物质与金属氢氧化物凝结或附聚，并附着在悬浮物上，使它们变得无活性。该方法有利地用于纸浆和/或造纸工艺。

摘要： Disclosed is a process for preparing a paper web. The paper web is prepared from a low-grade furnish, which contains low-grade pulps, such as recycled pulp and/or groundwood pulp, and which, in one preferred embodiment, is a newsprint furnish. In accordance with the disclosed process, a pre-flocculated filler is added to the furnish prior to forming the paper web from the furnish. Filler will be retained in the web, and retention of undesired components of the furnish in the web will be reduced as compared with newsprint in which a filler is incorporated via conventional processes. Another embodiment contemplates the incorporation of a pre-flocculated coated broke slurry into a paper furnish prior to paper formation. The paper web formed via the process of the invention will have improved properties as a result of the incorporation of the pre-flocculated filler or treated broke into the web.
摘要翻译：公开了一种纸幅的制备方法。纸幅由低级配料制成，其含有低等级纸浆，例如再生纸浆和/或研磨木浆，在一个优选实施方案中，它是新闻纸配料。根据所公开的方法，在从配料形成纸幅之前，将预絮凝的填料添加到配料中。填料将被保留在网中，并且与通过常规方法掺入填料的新闻纸相比，配料在纸幅中不需要的成分的保留将会降低。另一个实施方案考虑在纸形成之前将预絮凝的涂布的破碎浆料掺入纸配料中。通过本发明的方法形成的纸幅将由于将预絮凝的填料或经处理的破碎物结合到网中而具有改进的性能。

摘要： The invention relates to a method in a paper or pulp process to control the chemical state of the pulp and circulation water system. In the process one or more raw-material components (PROCESS WATER, TMP, PULP, REJECT) diluted in liquid, possible fillers, and one or more additives are mixed to form stock. In the method, the electrochemical state of at least one raw-material component (PROCESS WATER, TMP, PULP, REJECT) and/or the stock is regulated, without the regulation substantially affecting the pH values of the raw-material components (PROCESS WATER, TMP, PULP, REJECT) and/or of the stock.
