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。

SOLUTION: After coating an inner surface 2 as the back surface of a higher appropriate temperature of the inner and outer surfaces 2 and 3 of a ductile cast iron pipe 1 as an object to be coated at the appropriate temperature of 200°C, the ductile cast iron pipe 1 is forcibly cooled to the lower appropriate temperature by spraying cooling water from cooling water nozzles 6a and 6b and blowing air from an air nozzle 7, and the outer surface 3 as the front surface of the lower appropriate temperature is coated at the appropriate temperature of 70°C. Thus, the interval time from the coating of the inner surface 2 to the coating of the outer surface 3 is shortened, and the entire coating time is shortened. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To efficiently execute the suction of a coating material for an over- sprayed component by forming an air flow passage in which air flows from an aperture side to a recovering device side. SOLUTION: A special shaped pipe P is hung by a hook 15 and is carried in this state into a coating chamber 1a by a chain conveyor 10 when the coating of the special shaped pipe P is carried out in a coating booth 1. The door of a boot side wall is then closed and the spray coating by a coating gun 8 is executed in the state of operating the recovering device 35. The inside of the coating boot 1 is partitioned by a partition panel 20 to the coating chamber 1a and a recovering chamber 1b. This partition panel 20 is formed to a key shape in side view having a horizontal partition section 21 and a perpendicular partition section 22. The section between the horizontal partition section 21 and the ceiling 2 of the booth 1 is formed as the air flow passage 23. As a result, even if the powder coating material rises through a slit 24, the powder coating material is carried to the recovering chamber 1b and is recovered by the recovering device 35.

摘要： PROBLEM TO BE SOLVED: To obtain the subject composition, giving a coating film excellent, e.g. in flexibility and resistance to impact, by blending a powder coating composition of epoxy resin with a polyolefin resin or modification thereof to produce the powder coating material. SOLUTION: This composition comprises compounding (A) 100 pts.wt. of a powder coating composition of epoxy resin and (B) 10 to 100 pts.wt. of a polyolefin resin or modification thereof having a number-average molecular weight of 3,000 to 20,000. The component A contains a hardening agent, pigment, additive and the like, in addition to the epoxy resin. The component B may be a homopolymer or copolymer of 2-6C olefin. This composition can be obtained by mixing the components A and B at normal temperature, kneading the mixture by a kneader for powder coating, crushing the produced pellets and adjusting particle size distribution of the powder to a desired level. Thus, a 2-layered structure of epoxy and polyolefin resin layers is performed by a coating film forming process comprising one-coating and one-baking step.
