    • A method of forming a layer of coating of tin on an inner surface of a copper pipe by passing a substitutional electroless tin plating liquid through an inner portion of the pipe, comprising a first plating step in which the plating is done by regulating a deposition rate of a layer of coating of tin so that a value obtained by dividing a total copper ion concentration in the portion of the plating liquid which has passed through the inner portion of the copper pipe and just flowed out therefrom by a concentration of bivalent tin ions in the same plating liquid becomes not more than 0.8, and a second plating step in which the plating is done with the temperature of the plating liquid set higher than that of the plating liquid in the first plating step. A plating liquid preferably used is a plating liquid containing 0.05-0.3 mol/l of positive bivalent Sn ion, 0.5-2.0 mol/l of thiourea, 0.5-2.0 mol/l of sulfuric acid, 0.05-2.0 mol/l of alkyl benzene sulfonic acid and 0.5-5.0 g/l of nonionic surface active agent. A corrosion resisting internally tin-plated copper pipe used as a water supply pipe, a hot water supply pipe and a heat exchanger pipe can be manufactured in the form of a long size coil, and a layer of coating of tin thus formed has small scatter of thickness, and high adhesion and a high corrosion resistance.
    • 一种在铜管的内表面上形成锡涂层的方法,该方法通过使取代的无电镀锡液通过管的内部,包括第一镀层步骤,其中通过调节沉积速率进行电镀 的镀层,使得通过将通过铜管内部的电镀液的部分中的总铜离子浓度除以由二价锡离子浓度刚刚流出的值而得到的值 相同的电镀液变得不大于0.8,并且在第一电镀步骤中,在电镀液的温度设定为高于电镀液的温度的情况下进行电镀的第二电镀步骤。 优选使用的电镀液是含有0.05-0.3mol / l的正二价Sn离子,0.5-2.0mol / l的硫脲,0.5-2.0mol / l的硫酸,0.05-2.0mol / l的烷基苯 磺酸和0.5-5.0g / l非离子表面活性剂。 用作供水管的耐腐蚀内部镀锡铜管,热水供应管和热交换器管可以制成长尺寸线圈的形式,并且由此形成的锡涂层具有小的散射 的厚度,高粘合性和高耐腐蚀性。

    • An object of the present invention is to provide a headbox for a paper machine in which correction of the fiber orientation of paper is possible over the entire width of the C/D direction, regardless of the slice width, and in which the fiber orientation in the direction of paper thickness can be corrected over the entire thickness of the paper. A headbox (1) for a paper machine according to claim (1) of the present invention discharges paper raw material onto a wire as a raw material jet gj from a slice (5) which is supplied with the paper raw material, and comprises orientation correcting means (h3) for correcting the pulp fiber orientation by supplying paper raw material, which is extracted from a taper header (2) in which paper raw material for a main flow is stored, or from a correction-only taper header (2s) in which paper raw material for correcting the pulp fiber orientation is stored, as a correction flow to a single location in a central portion of the slice (5) via at least one flow control valve (b3).
    • 本发明的一个目的是提供一种用于造纸机的流浆箱,其中不管切片宽度如何,在C / D方向的整个宽度上可以校正纸的纤维取向,并且其中纤维取向 可以在纸张的整个厚度上校正纸张厚度的方向。 根据本发明的权利要求(1)的造纸机的流浆箱(1)将纸原料从作为原料射流gj从作为纸原料的切片(5)排出到线材上,并且包括取向 用于通过供给从其中存储有用于主流的纸原料的锥形集管(2)中提取的纸原料或从仅校正锥形头(2s)提取的纸浆纤维取向来校正纸浆纤维取向的校正装置(h3) 其中用于校正纸浆纤维取向的纸原料经由至少一个流量控制阀(b3)作为校正流被存储到切片(5)的中心部分中的单个位置。
