Abstract:
A liner and method of application for use on a metal surface to protect metal structures such as cooling towers, evaporative condensers, and other liquid containing vessels such as tanks from corrosion, leaks, and wear. The liner is an inexpensive apparatus and process comprising a coated metal having a second sealing and bonding layer and a third protective sealing layer. The liner method comprises applying an organic bonding layer onto the galvanized substrate, and applying an elastomeric barrier coating to the bonding layer. The barrier coating material is applied to preseal the seams between adjoining panels assembled to form the basin. The barrier coating is applied to the entire inside of the basin to form a homogenous barrier coating extending out of the basin. The liner edge is isolated from the basin by extending the liner to a point between the basin and an upper section. The liner comprises galvanizing layer, a bonding layer on the galvanized metal, and an elastomeric third layer on the bonding layer. The liner further comprises preseals at the seams, corner molds and link holes in the substrate to attach and protect the liners integrity.
Abstract:
A coating film is formed on a surface of a coating object by adhering a coating powder to the coating object by spraying the coating powder from an electrostatic gun together with a compressed gas. A voltage not smaller than 80 kV but not larger than 100 kV is applied between the electrostatic gun and the coating object. Moreover, a current flowed between the electrostatic gun and the coating object is set to be not smaller than 10 μA but not larger than 20 μA. Further, a pressure of the compressed gas for spraying the coating powder is set to be not smaller than 3 kgf/cm2 but not larger than 6 kgf/cm2.

Abstract:
A powder hopper is provided with a low turbulence zone for supplying powder to a spray gun. The low turbulence zone is defined by a baffle inside the hopper with the low turbulence zone being within a volume of the baffle, and an annular zone between the baffle and the hopper is used to bulk feed powder into the hopper. The low turbulence zone may alternatively be in the annular zone with powder added to the volume of the baffle. One preferred application for this hopper is in connection with the use of fine powder coating materials to coat the interior of small diameter cans.
