摘要： PROBLEM TO BE SOLVED: To provide a corrosion-preventive structure of pipeline which simply improves corrosion-preventive performance of buried pipeline.SOLUTION: A corrosion-preventive structure of pipeline in which an outer circumference of buried metal pipe is covered with polyethylene sleeve, adjacent edge parts of the polyethylene sleeves are overlapped with each other, a rubber band is wound around the outer circumference of overlapped part of the polyethylene sleeve and, thereby, water permeation from the edge part of the polyethylene sleeve is prevented, comprises water-absorbing swelling material disposed between the outer circumference of the pipe and the inner circumference of the rubber band. Thereby, even when water permeation occurs from the edge part of the polyethylene sleeve to the inner side, the water-absorbing swelling material is swollen, therefore, closes an advancing path of water, strengthens the tightening by means of the rubber band, stops the water permeation to the buried pipeline and can prevent corrosion of the pipeline.
摘要翻译：要解决的问题：提供简单提高埋管线路防腐蚀性能的管道防腐结构。解决方案：埋管金属管外周覆盖聚乙烯套管的管道防腐结构，相邻聚乙烯套筒的边缘部分彼此重叠，橡胶带缠绕在聚乙烯套筒的重叠部分的外圆周上，从而防止从聚乙烯套筒的边缘部分渗透水分，包括吸水膨胀配置在管的外周与橡胶带的内周之间的材料。因此，即使从聚乙烯套筒的边缘部到内侧发生水渗透，吸水膨胀材料膨胀，因此封闭水的前进路径，通过橡胶带增强紧固，停止水渗透到埋地管道，可以防止管道腐蚀。

摘要： PROBLEM TO BE SOLVED: To provide a powder coating recovery treatment apparatus which enhances the recovery efficiency when the metal powder included in the powder coating is removed.
SOLUTION: The powder coating recovery treatment apparatus is characterized by incorporating the recovered powder coating W into a fluid tank 20 to maintain a fluid state and arranging a magnet 31 within the fluid tank 20 so that the metal powder included in the recovered powder coating W is removed by adsorbing the same to the magnet 31. A porous plate 22 is installed to the bottom plate of the fluid tank 20. The gas G in a gas reservoir 23 is supplied through the pores 24 of the porous plate 22 and the powder coating W is agitated. The magnet 31 is arranged on the porous plate 22. A lot of the metal powder can be adsorbed to the magnet because the chance of access of the metal powder included in the powder coating W to the magnet 31 is increased by installing the magnet 31 within the fluid tank 20. Therefor, the removal efficiency can be enhanced. Also, the transferring step and transferring working of the powder coating is simplified and the constitution of the apparatus can be simplified because the necessity to provide the removal step and removal device excluding the fluid tank 20 is eliminated.

摘要翻译：要解决的问题：提供一种除去粉末涂料中包含的金属粉末时提高回收效率的粉末涂料回收处理装置。解决方案：粉末涂料回收处理装置的特征在于将回收的粉末涂料W并入流体箱20中以保持流体状态，并将磁体31设置在流体箱20内，使得包含在回收粉末中的金属粉末通过将其吸附到磁体31而除去涂层W.多孔板22安装在流体槽20的底板上。气体储存器23中的气体G通过多孔板22的孔24供给，粉末涂层W被搅动。磁体31设置在多孔板22上。由于通过将磁体31安装在磁体31内而使包含在粉末涂层W中的金属粉末进入磁体31的机会增加，所以许多金属粉末可以被吸附到磁体上流体箱20.因此，可以提高去除效率。此外，由于不需要提供除了流体箱20之外的除去步骤和除去装置，所以简化了粉末涂层的转印步骤和转印加工，并且可以简化装置的结构。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To obtain a lining layer to the vessel inside inexpensive, and having acid resistance and abrasion resistance.
SOLUTION: While moving a rotary Hume pipe 1 in its vessel axis direction, aggregate b and molten sulfur c are supplied to the vessel 1 inside to mix these by the rotation, and the mixture is subjected to lining a to the vessel inside using the molten sulfur c as a binder of the aggregate b. The recycling of sulfur or the like refined by desulfurization of petroleum and natural gas which are not conventionally sufficiently recycled is facilitated. Using the sulfur, a sulfur-possessed acid-resistant and abrasion-resistant vessel 1 of lining to the vessel inside can be obtained at a low cost. If the vessel 1 employs a hardly deformable vessel by strength in a diameter direction such as ductile cast iron and the Hume pipe, due to its resistance to deformation, the above-described performance can be obtained for a long period of time even in sulfur mixture lining a without toughness.

摘要翻译：要解决的问题：为了在容器内部获得廉价的并具有耐酸性和耐磨性的内衬层。
解决方案：在旋转休谟管1沿其容器轴线方向移动时，将聚集体b和熔融硫c供应到容器1内部以通过旋转进行混合，并将混合物经受衬里a到容器内部使用熔融硫磺作为聚集体b的粘合剂。通过不常规地充分再循环的石油和天然气的脱硫来精炼的硫等的再循环便利。使用硫，可以以低成本获得含硫耐酸耐磨损容器1的衬里到容器内部。如果容器1由于其耐变形性而在诸如球墨铸铁和休斯管之类的直径方向上采用几何变形的容器，所以即使在硫混合物中也可以长期获得上述性能衬里没有韧性。版权所有（C）2008，JPO＆INPIT
