摘要： A method for continuously producing a mat of cellulose fibres intended for producing roofing elements made from bitumen-impregnated cellulose fibres, from a dilute slurry of cellulose fibres spread by a headbox on a dewatering fabric of a forming table having a predefined width, the dewatering fabric moving between an inlet of the forming table at the headbox side and an outlet of the forming table, moving the dilute slurry towards the outlet, gradually removing the liquids of the dilute through the dewatering fabric during the movement to obtain, at the outlet, the mat having a thickness of at least 2 mm, the dilute slurry having a certain level of pre-existing mineral materials. The method involves adding mineral material to the cellulose fibres by spraying a controlled quantity of aqueous solution or dispersion of mineral fillers over the width of the forming table onto the surface of the dilute slurry.

摘要： Methods of making the burnthrough resistant non-woven mat include forming the mat from glass fibers and at least two binders, a first binder having a vinyl component and a second binder having a strengthening component. The vinyl component may be, for example, ethylene vinyl chloride, and the strengthening component may be, for example, melamine formaldehyde. In one method, the vinyl component is added to the glass fibers by a beater addition process and the strengthening component is sprayed onto the glass fibers. The burnthrough resistant non-woven mat may be used in conjunction with an insulation blanket, and may be especially suited to use in insulating aircraft.

摘要： Formulations and methods for papermaking are disclosed herein using one or more volatile debonders, where the volatile debonder forms a solution or an emulsion with water in a paper precursor, and where the volatile debonder is evaporable from the paper precursor before the paper precursor is completely dried to form a paper sheet during papermaking. Two volatile debonders having different boiling points can be used, where they are miscible in water and in each other, and where one volatile debonder has a higher molecular weight and the other volatile debonder has a lower boiling point.

摘要： A method for treating a web of paper or board with a wetting substance or calendering the web prior to the cylinder dryer section of a paper- or boardmaking machine while the solids content of the web is still very low, typically in the range of 10–60%, wherein the web can be conveyed when so desired fully supported from the wire section of the paper- or boardmaking machine up to the winder, while simultaneously utilizing the quality benefits obtained from a controlled reduction of the web moisture content and dewatering of the same. The web is conveyed supported by a transfer belt (9) through at least one web surface treatment apparatus such as a coater station (S1B) or a calender prior to passing the web to the first dryer cylinder group (1) of the paper- or boardmaking machine. One nip (11, 13) supported by a transfer belt (9) is suitable for dewatering simultaneously with the application of a treatment substance to the web. The dewatering nip (11, 13) may be formed between a transfer belt (9) and the wire (2) of the wire section or the felt (14) of the press section.

摘要： A new foam coated nonwoven fibrous mat having properties particularly suited for a facer on gypsum wallboard, laminates made therefrom and the method of making the mat is disclosed. The mat preferably contains a major portion of glass fibers and a minor portion of a resinous binder. The foam coating is permeable and reduces fiber dust and abrasion experienced in the past with relatively coarse, relatively inexpensive glass fibers in the mat. Contrary to previous methods, the foam coated fibrous mat is made in-line on a wet mat forming production line by applying a wet foam binder onto a wet, fibrous web followed by drying and curing in-line.

摘要： A method and apparatus for incorporating feature substances into a still moist but already sufficiently consolidated paper web provides for directing a feature substance suspension onto the surface of the paper web as a laminar jet with low jet pressure. A special pressure control circuit ensures that the jet pressure is always constant regardless of the number of parallel feature substance suspension jets directed onto the paper web. This makes it possible to incorporate a great variety of line codings in paper under the same process conditions without any visible changes in fiber structure occurring in the paper.
