A paper tube that functions as a core of a rolled sheet, the paper tube includes an inside base paper layer at an inside peripheral surface of the paper tube; and an outside base paper layer at an outside peripheral surface of the paper tube, polyphenol and glycerin being impregnated in at least one of the inside base paper layer and the outside base paper layer.
摘要:
Disclosed is an apparatus and method for forming lubricant recesses having minute configurations by applying a photolithograph method in a curved inner surface, such as a cylinder bore surface of a cylinder block, the inside of a cylinder liner, the inside of a compressor cylinder, a big end of a connecting rod, a big end bearing, a shaft insertion hole of a rocker arm, or the like in an internal combustion engine.
摘要:
A method and apparatus is disclosed for additive manufacturing and three-dimensional printing, and specifically for extruding tubular objects. A print head extrudes a curable material into a tubular object, while simultaneously curing the tubular object and utilizing the interior of the cured portion of the tubular object for stabilizing and propelling the print head.

Methods and systems for providing cleaning and providing barrier coatings to interior wall surfaces of small diameter nonmetal and composite piping systems in buildings, swimming pools, underground pipes, in-slab piping systems, piping under driveways and various liquid transmission lines. An entire piping system can be cleaned in one single pass by dry particulates forced by air throughout the building piping system by an external generator, and the entire piping system can be coated in one single pass by a machine connected exterior to the piping system. Small pipes can be protected by the effects of water corrosion, erosion and electrolysis, extending the life of piping systems such as plastics, PVC (polyvinyl chloride), composite materials, polybutylene. Coatings can be applied to pipes having diameters of approximately ⅜″ up to approximately 6″ so that entire piping systems such as potable water lines, natural gas lines, HVAC piping systems, drain lines, and fire sprinkler systems in single-family homes to apartments to high-rise hotel/resort facilities and office towers, apartment and condominium buildings and schools, can be cleaned and coated to pipes within existing walls. The coating forms at least a 4 mils or greater covering inside of pipes. Buildings can return to service within approximately 24 to approximately 96 hours.
摘要:
The present invention is directed to a certain method of catalytically coating a honeycomb monolith, in particular a so-called flow-through monolith. These types of monoliths can be quite precisely be coated by a method using an indirect coating via a displacement body. The present invention further improves this method through controlling the process by monitoring the certain measures.
摘要:
Two-part coating compositions are described comprising an aliphatic cyclic secondary amine and methods of coating surfaces of a (e.g. drinking water) pipeline.
摘要:
A method to protect and modify surface properties of articles is disclosed. In one embodiment of the method, an intermediate layer is first deposited onto a substrate of the article. The intermediate layer has a thickness of at least 2 mils containing a plurality of pores with a total pore volume of 5 to 50% within a depth of at least 2 mils. A lubricant material is deposited onto the intermediate layer, wherein the lubricant material infiltrates at least a portion of the pores and forms a surface layer. The surface layer can be tailored with the selection of the appropriate material for the intermediate layer and the lubricant material, for the surface layer to have the desired surface tension depending on the application.
摘要:
A method for regeneration of internal conduit surfaces by thermal projection of metals, includes inserting a device including a vehicle having a rolling assembly to permit rolling of the vehicle and carrying a thermal projection system, through a manhole in a conduit installation, including the steps of inserting the device in a conduit with the rolling assembly in a retracted position, and expanding the rolling assembly inside the conduit until the device is centered in the conduit; inserting electrical, pneumatic and/or hydraulic conduits and conduits for supplying metal to be thermally projected, through the manhole, such that the conduits are connected with the vehicle; positioning a regeneration device including the thermal projection system connected with the vehicle by a remote-control pulling system in a particular position to be regenerated; thermally projecting metal from the regeneration device; advancing the vehicle and connected regeneration device to a new regeneration position.
