Abstract:
Method of applying and/or heat melting with optional contemporaneous or subsequent thermosetting thermally meltable powdered polymers by using hot air generators and convectors with variable velocity output and temperature. (Heats Guns for spray powder coatings or powder adhesives).
Abstract:
A method for providing a protective coating on an underground or underwater pipeline tube (1), said coating including at least one polypropylene and/or polyethylene layer. The method comprises the steps of depositing at least one layer (2) of anticorrosive epoxy material, at least one layer of adhesive material (3), or at least one layer of a material forming a protective shell (4). The deposition process is carried out by spraying particles of said materials in a controlled atmosphere and in the presence of a flame using at least one particle spraying torch.
Abstract:
A high temperature thermal sprayable material, such as a metal or metal oxide, is adhered to the surface of a plastic particle to form a cladding layer thereon. The high temperatue material cladding layer provides a thermal barrier that allows use of the plastic in a high temperature thermal spray process to create a duplex coating containing plastic.
Abstract:
Method of a coating a roll in a paper machine with powder of thermo plastic and/or speciality plastic. The coating is carried out by spraying by using hypersonic plasma.
Abstract:
A coated prosthetic implant and a method of forming a continuous coating of highly crystalline polymer over a prosthetic implant by means of passing particles of polymer through a high temperature plasma and subsequently depositing the molten particles over the implant surface. This invention is especially useful for coating polymer composite implants, such as a femoral insert for a hip joint prosthesis, with a coating of poly(aryl-ether-ketone).
Abstract:
Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. Also described are systems for performing the various processes.
Abstract:
A fabric or belt and a method for forming such a fabric or belt, including a base support structure and at least one coating with the coating being applied by a thermal spray process.
Abstract:
Application of a resin to a pool surface to provide a colored finish that is ultraviolet resistant. The resin may be a powder that can be melted at a fairly low temperature and applied to the pool surface. A first later of resin may be applied (thermally sprayed) to an epoxy layer that is applied to the pool surface after the epoxy has become tacky and before it has cured to provide better adhesion and cause the resin and the epoxy to blend into a single layer. An additional layer of resin may be applied after the epoxy and the first layer of resin fully cured. After the second layer of resin has cured an additional layer may be applied to provide designs and/or markings. The designs/markings may be produced with tape and/or stencils and the next layer may be applied to the non-covered areas to provide the desired look.
