Patch repair system for collapsible fuel and water tanks
InactiveUS20050112968A1High crystallinityHighly elasticMedical patchesPolyureas/polyurethane adhesivesPolyesterElastomer
The invention is a patch system for repairing collapsible fuel tanks, water tanks, inflatable boats, and other articles fabricated from a flexible structural fabric coated with a polymer. The coated structural fabric is made of nylon or polyester synthetic fibers or a blend thereof, which are coated with a thermoplastic elastomer. The structural coated fabric is coated with a thermoplastic elastomer that is a urethane (TPU), or a TPU alloy polymer. Likewise, the patch is a urethane adhesive having a latent cure coated on a TPU film. The patch can also have an integral reinforcing fabric for applications requiring a higher tensile patch. In the invention, the urethane adhesive of the patch is solvent activated by the application of a thin coating of a volatile, substantially low odor, fugitive solvent like acetone or MEK. While in the activated state, the adhesive has much less cyrstallinity and a lot more tack. The solvent activated adhesive has good wetting, and aggressively wets out and adheres to the surface of the TPU coating on the tank. The activated adhesive side of the patch is pressed against the surface of the tank. The solvent will also partially etch the thermoplastic urethane polymer coating on the tank fabric, and rapidly diffuses therein, ultimately evaporating to the surroundings. The cross-linkable urethane adhesive contains a blocked isocyanate and, preferably, an uretdione. The reduced cyrstallinity in the adhesive imparts greater freedom to the blocked isocyanate that can, depending on the equilibrium of the system, begin to cross-link the adhesive. The curing process can be accelerated through the application of heat, albeit will slowly progress to a cured state at ambient conditions.

Local degraded area repair and restoration component for pressure retaining items
InactiveUS6860297B2Simple and safe and cost-effective and methodReduce eliminateLayered productsLaminationMaterial DegradationEngineering
What is new in the art to which my invention pertains is that it allows for a repair or restoration of a pressure retaining item that has local material degradation to an acceptable state of condition for continued operation without the need to cut out the degraded section of material or breach the pressure boundary of a pressure retaining item. Common methods of repair include removal of degraded or affected material section and replacement with a new section of equivalent material by joining the new material to an existing item at a location of adequate thickness using full or complete penetration welds. This type of repair may be referred to in the industry as a “flush patch repair”. An additional type of repair where a section of material degradation may be localized is a “weld build-up repair’ wherein weld metal is deposited onto the existing area of affected material to return the material to its original thickness. Both “flush patch repair” and weld build-up repair” methods require breaching of the pressure boundary integrity of a pressure retaining item to implement a repair. The invention does not require breaching a pressure boundary.

Method for locally repairing bricked ladle working liner
The invention discloses a method for locally repairing a bricked ladle working liner. The method comprises a step of slag line brick patch repair and a step of wall-wrapping brick patch repair. In the step of slag line brick patch repair, the damaged part is dismantled in the shape of an inverted triangle and then replaced by ladle bricks of the original material and shape after dismantling. In the step of wall-wrapping brick patch repair, the patch repair is performed by local transverse dismantling method in which a severely-damaged ladle brick and two bricks on the left and the right sides and concentric to the ladle brick are dismantled using a pneumatic pick, which are replaced by bricks of the original material and shape after dismantling. The method disclosed by the invention adopts the ladle bricks of the original material and shape, does not need much investment, prevents the whole ladle from being dismantled due to local severe damage, maintains the original service life of the ladle by means of patch repair, and reduces the cost of refractory material per ton steel. For a low-life ladle with a local damage, the whole ladle does not need to be out of service in advance or dismantled by means of patch repair, which can effectively reduce the labor intensity of workers, reduce the discharge of waste refractory materials and bring good environmental benefits.
