Abstract:
A material film forming method is provided which comprises coating a liquid material on a surface of a substrate to form a material film of the liquid material the on the surface of the substrate, while rotating the substrate, and drying the material film, while rotating the substrate and letting air or nitrogen gas blow onto a predetermined area of the material film.
Abstract:
A sprayable protective coating for preventing excessive aircraft and aircraft engine component deterioration caused by environmental variations comprises a water borne latex-based mixture, an additive for controlling the dielectric constant of the cured coating, and a catalyst for enabling the chemical reaction between the additive, de-ionized water for thinning material and the latex-based liquid. The process for applying and curing the coating uses a robotic spraying device and an iterative heating and soaking curing procedure.

Abstract:
A method and an appliance are disclosed for the non-thermal drying of articles, in particular motor vehicle bodies, freshly painted with a water-based paint. The articles to be dried are subjected to dry air by forced convection in a drying tunnel and the moisture-laden air is dried in an air drying device by condensation to a specific target value of absolute residual moisture. So that fluctuations in the incidence of moisture can be leveled out with a low degree of inertia, with the high condensation performance remaining unchanged, only a fraction of the circulated air which is adapted in size, as required, is dried in the air drying device to a residual moisture markedly below the circulating-air target moisture, and the remaining untreated part of the circulated air is led back into the drier housing after being intermixed with the dried part-air stream.
Abstract:
The method of coating a substrate with plurality of layers of coatings includes moving the substrate along a path through the coating station. A composite layer is formed of first and second coating fluids. The substrate contacts the flowing composite layer to interpose the first coating fluid between the substrate and the second coating fluid. The composite layer is doctored with a gas from a gas knife to remove some portion of the composite layer from the substrate.
Abstract:
A method for the production of a photographic coating support material includes a vacuum drying of the synthetic resin and the master batches as well as a storing and transport these products in a closed system with cleaned and dried air.
Abstract:
An apparatus for coating a hydrophilic film which includes a light reaction chamber having UV lamps on either side of the film, two cooling fans and a solvent deflation fan. There are also an air drying plates and coating nozzles.
Abstract:
A method of powder coating the inside of tubular goods, such as oil field pipe and the like, by connecting one end of the pipe to a means for producing a flow of compressible gases therethrough. The other end of the pipe is open to atmospheric pressure. A valve means is connected upstream of the pipe between the inlet end thereof and a container for holding a single charge of plastic powder. The charge of powdered plastic is isolated upstream of the pipe inlet. The charge is of sufficient size to coat the entire inside peripheral wall surface of the pipe with a substantial uniform coating of plastic. The pipe is heated above the softening temperature of the plastic and rotated so that when the valve is opened air flows through the pipe and establishes a pressure gradient across the entire length of the pipe to cause the captured charge of plastic to form a pocket of dispersed plastic particles which is forced through the pipe by the air flow, causing plastic particles to be deposited and fused to the hot rotating inner surface of the pipe.
Abstract:
A method for treating plastic containers with a resin to improve barrier properties thereof including conditioning with an ionizing gas, dipping container in latex of barrier resin and drying container including removing drop from bottom thereof. Apparatus for carrying out the process is shown.
