摘要： The aqueous dispersions from the polymerization of fluorinated thermoplastics can be worked up to a high value product (e.g., substantially purified of cations resulting from the polymerization) in a continuous manner, if the cations are first removed from the aqueous dispersion, the dispersion is then compressed and decompressed through small openings, thereby being coagulated, the coagulated phase is washed on a filter and partially dewatered, subsequently broken up to give a free-flowing product and this is dried to the desired residual moisture content. Qualitatively high value products, which can be directly fed to a melt extruder, are thus obtained with high throughputs.

摘要： A process for reducing the nitrogen oxide content in waste gases of combustion installations is disclosed. The present process is a catalytic reduction with ammonia wherein the nitrogen oxide-containing waste gases are conducted past temperature-resistant structures which are coated with a mixture of one or more aluminosiliciates of the faujasite group, silica sol and/or silicates and a copper compound.

摘要： The present invention relates to a new type of diaphragm for use in electrolytic cells for the production of hydrogen and oxygen, which diaphragm consists essentially of fluorocarbon polymers which have been oxidized to improve its wettability. According to the present invention the improved diaphragm is characterized in that the fluorocarbon polymers are present in the form of monofilaments, that only the surface of the monofilaments is oxidized, and that the monofilaments are woven into a fabric. In a preferred embodiment the monofilaments have a diameter of less than 0.25 mm in the weft and less than 0.15 mm in the warp. The permeability of gas in the dry state is from 50 to 1000 l.dm.sup.-2.min.sup.-1 when the difference in pressure is 200 Pa. Preferably the monofilaments are evenly spaced to effect even size of the pores between the monofilaments.
摘要翻译：本发明涉及用于生产氢气和氧气的电解池中的新型隔膜，该隔膜基本上由已被氧化以改善其润湿性的碳氟聚合物组成。根据本发明，改进的隔膜的特征在于，氟碳聚合物以单丝的形式存在，只有单丝的表面被氧化，并且将单丝编织成织物。在优选实施例中，单丝在纬纱中的直径小于0.25mm，而在经纱中的直径小于0.15mm。当压力差为200Pa时，干燥状态下的气体的渗透率为50-1000l.dm-2.min-1。优选地，单丝均匀间隔开以实现单丝之间的孔的均匀尺寸。

摘要： The invention describes a sealing material from polytetrafluoroethylene fibers, whose staple length is in the range of from 1 to 20 mm. They are intimately mixed with graphite; oil and finely divided polytetrafluoroethylene being advantageously added. The portion of PTFE fibers is at least 50% by weight, the portion of graphite is from 10 to 30% by weight, and the portion of finely divided PTFE is from 5 to 15% by weight. As PTFE fibers there are also used those which have been obtained by machining sintered PTFE resin. The sealing material is formed into tablets or half-rings.The seals prepared are marked by their applicability at uncommonly high pressures.
