Abstract:
According one embodiment, a film forming apparatus includes a stage, a coating section, a vapor supply section, a blower section, and a controller. On the stage, an coating target is placed. The coating section applies a material to a predetermined region on the coating target placed on the stage to form a coating film. The vapor supply section generates solvent vapor capable of dissolving the coating film. The blower section blows the solvent vapor generated by the vapor supply section onto the coating film on the coating target placed on the stage. The controller controls an amount of the solvent vapor to be blown by the blower section so that: the coating film is dissolved; viscosity in a part of the coating film on a surface layer side is lower than that in a part thereof on the coating target side; and the viscosity in the part on the surface layer side and the viscosity of the coating target side take such values that prevent the coating film on the coating target from spreading.
Abstract:
[Object] There are provided a fluorocarbon resin composite having improved abrasion resistance while nonadhesiveness, which is a feature of a fluorocarbon resin, is maintained, cookware, and a roller and a belt for use in office automation equipment.[Solving Means] A fluorocarbon resin composite includes a fluorocarbon resin layer on a base, in which a fluorocarbon resin constituting the fluorocarbon resin layer is crosslinked by electron beam irradiation, and the base has a desired shape obtained by machining. The fluorocarbon resin is composed of a tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer, polytetrafluoroethylene, or a mixture of the tetrafluoroethylene-perfluoro(alkyl vinyl ether) copolymer and polytetrafluoroethylene. A fluorocarbon resin composite, cookware, and a roller and a belt for use in office automation equipment are each produced by applying an uncrosslinked fluorocarbon resin on a base, subjecting the fluorocarbon resin to electron beam irradiation in a low-oxygen atmosphere to crosslink the fluorocarbon resin while the temperature of the fluorocarbon resin is maintained at a temperature equal to or higher than the melting point of the fluorocarbon resin, and machining the base into a desired shape. There is also provided methods for producing them.
Abstract:
An aqueous polymer coating composition containing at least one latex or pseudolatex is coated on a substrate in a high humidity coating process followed by heat treatment of the coated substrate above the film forming temperature of the coating at low humidity. The coated substrate gives a stable reproducible dissolution profile substantially insensitive to temperature or humidity conditions upon storage. The high humidity coating process is achieved by addition of water to the coating chamber through dilution of the coating formulation or humidification of inlet air. Contrary to the conventional low humidity coating process, residual water is retained in the coating layer of the coated substrates in the coating step. When the coated substrates are heat treated at a temperature greater than the minimum film forming temperature, the residual water in the coating layer will ensure adequate capillary force for the completion of film coalescence. High humidity heat treatment is not needed.
Abstract:
A method and apparatus for controlling the thickness of a thin film or thin layer of discrete particles or of a heterogeneous mixture characterized in that the interfacial tension forces between the solution or suspension and its environment are used as the driving forces to evenly spread the solution, suspension or mixture while the solvent evaporates and/or dilutes.
Abstract:
The boundary layer of a substrate is exposed to a low-energy inert-gas atmospheric plasma that disrupts the layer's bonds, thereby permitting the removal of most oxygen from the surface of the substrate. The substrate is then passed through an exhaust section to remove the disrupted boundary layer prior to conventional plasma treatment. The subsequent plasma treatment is carried out in conventional manner in a substantially oxygen-free environment. As a result of the invention, the high surface-energy levels provided by plasma treatment are more lasting and plasma applications requiring a substantially oxygen-free environment are more efficient.

Abstract:
According to the method and the apparatus for curing a coated film of the present invention, since an ionization radiation is applied after the O2 concentration in the near-surface layer within 1 mm above the surface of the coated film is adjusted to 1000 ppm or lower, the coated film can be sufficiently cured by irradiation of the ionization radiation. In other words, according to the method and the apparatus for curing a coated film of the present invention, since the O2 concentration in a thin near-surface layer on the surface of a coated film is decreased, the coated film can be sufficiently cured by irradiation of an ionization radiation. As a result, the amount of inert gas supplied upon irradiation of an ionization radiation can be reduced, and downsizing and cost reduction of equipment can be achieved.
