Polyurethane bonding process for fuel bladders
A method of bonding a metal fitting to a polyurethane structure, the method comprising abrading a surface of the metal fitting with an abrasive; cleaning the metal fitting with a solvent; cleaning a surface of the polyurethane structure with an alcohol; applying a primer to the surface of the metal fitting; applying an adhesive to the surface of the metal fitting and the surface of the polyurethane structure; applying a liquid polyurethane compound to the surface of the metal fitting and the surface of the polyurethane structure; and pressing the surface of the metal fitting against the surface of the polyurethane structure to form an assembly. The primer can comprise a first resin and a first catalyst in a ratio of about 1.1 to 1; the adhesive can comprise a second resin and a second catalyst in a ratio of about 3 to 1; and the liquid polyurethane compound can comprise a third resin and a third catalyst in a ratio of about 10 to 1.
METHOD FOR BONDING RUBBER AND ADHESIVE FOR BONDING RUBBER
The invention relates to a high-strength and permanently elastic curable adhesive for bonding at least two surfaces, of which at least one surface is a surface of a permanently elastic plastic wherein the adhesive is an adhesive that cures in at least two different hardening mechanisms, wherein the first hardening mechanism comprises a chemical reaction to form a chemical bond including a sulphur atom, and the second hardening mechanism comprises the formation of crystalline structures from amorphous polymers. The invention also relates to a method for high-strength and permanently elastic bonding of at least two surfaces to one another, of which at least one surface is that of a permanently elastic plastic, by means of such an adhesive, said method comprising the steps of: applying the adhesive to at least a first of the surfaces to be connected, ensuring conditions under which at least the first hardening mechanism of the adhesive can take place, bringing the first surface into contact with the second surface, and ensuring conditions under which the second hardening mechanism of the adhesive can take place.
Liquid shim adhesive injection tool
A tool for installing a liquid shim material into a clearance formed between an assembly first and second component includes a body having a first end and a second end. The first end includes a planar surface and the second end includes a first surface and a second surface arranged at an angle to the first end and to one another. At least one hole is formed in the body. The at least one hole extends from the first end to the second end and is configured to provide a passageway through the body. The tool is arranged adjacent the assembled first and second component such that the passageway formed by the at least one hole is arranged in fluid communication with the clearance.
METHOD FOR OBTAINING A JOINT BETWEEN ELEMENTS OF DIFFERENT MATERIALS
A joint between at least one element of metal material and at least one element of plastic material is obtained by pressing these elements in contact against each other, with a simultaneous application of heat. A cladding of metal material and/or of plastic material is applied above the joint by additive manufacturing technology.
System and Method for Thermal Treatment of Surface Bonding Optical Patch Cord
A system, apparatus and method for thermal treatment of surface bonding optical is provided. An optical patch cord is surface bonded via thermal treatment with a tracer optical fiber which provides patch cord tracing in a bonding apparatus. During the process, the optical patch cord is also thermally treated to have the mechanical stress contained in its jacket relieved by rollers in the bonding apparatus to solve the patch cord shrink-back problem.
CORNER PROFILES AND/OR CORNER REINFORCEMENT FOR LINERS AND LININGS SUITABLE FOR USE WITH TANKS AND OTHER STORAGE/CONTAINMENT VESSELS
The present disclosure relates to corner profiles and/or corner reinforcement for liners and linings that are suitable for use with tanks and other storage/containment vessels, such as process tanks, immersion tanks, indoor or outdoor containment pits, gravity feed conduits (e.g., concrete trench, canal, or drain, etc.) for transferring or conveying liquid, grain storage tanks or containers (e.g., dielectric or electrically non-conductive liners for grain storage, etc.), etc. The present disclosure also relates to tanks and other storage/containment vessels including liners and linings with corner profiles and/or corner reinforcement. Additionally, the present disclosure relates to methods, systems, and apparatus for providing corner profiles and/or corner reinforcement for liners and linings.
Dispenser Device for Applying Structural Adhesive and A Method Using Such A Dispenser Device
This invention relates to a dispenser device for and a method of applying a structural adhesive to an application surface on a wind turbine blade structure, wherein the dispenser device comprises a housing forming a reservoir configured to hold a surplus of structural adhesive during dispensing. The reservoir is connected to an inlet for supplying the structural adhesive and an outlet for dispensing the structural adhesive. The outlet may be a side opening arranged in an exchangeable housing part. The dispenser device may also comprise an adjustable mechanism connected to a plate member configured to be moved relative to the side opening. The operation of the adjustable mechanism is controlled via a control unit or a control element. The exchangeable housing part or adjustable mechanism enables the cross-sectional profile, the width and/or the height of the dispensed structural adhesive to be changed before or during dispensing.
APPARATUS AND METHOD FOR PRODUCING SEALING RINGS, ALSO A CONTROL DEVICE AND USE THEREOF FOR THIS PURPOSE, USE OF A ROTATABLY MOUNTED DISC FOR THIS PURPOSE, AND A SEALING RING
A device for producing sealing rings made of an endless-material. The device includes a feeder unit which conveys and positions the endless-material in a cutting position, a cutting unit which cuts off a section of the endless-material, a gripper unit which grips and displaces the endless-material or the section of the endless-material and which controls a displacement of at least one free end of the section of the endless-material along a predefined path of motion in and/or out of a wetting position, a control device connected with the feeder unit, the at least one gripper unit and/or the cutting unit, and a feeding device for a bonding fluid. The feeding device is connected with the control device and is arranged so that the bonding fluid is deposited in a controlled manner on the at least one free end of the section of the endless material in the wetting position.
LOAD INTRODUCTION DEVICE AND METHOD FOR ADHESIVE BONDING OF A LOAD INTRODUCTION DEVICE
A load introduction device and a method for adhesive bonding of a load introduction device for fiber composite materials is disclosed. A sealant, particularly a first adhesive is used in the creation of a cavity and in the creation of a secured arrangement for the injection of adhesive into the cavity.
METHOD FOR REPAIRING DELAMINATION AND MOISTURE BY HEAT, PRESSURE AND ADHESIVE
A method for repairing aircraft window laminates in which two plies have become separated to create a void, and wherein moisture may have entered through an edge of the window laminate and into the void. The method includes the steps of: placing the window laminate in a vacuum bag and inserting the vacuum bag containing the window laminate into an oven or autoclave for a minimum of ten minutes at a minimum temperature of 120 degrees Fahrenheit to remove the moisture between the plies; removing the vacuum bag and window laminate from the oven, and removing the window from the vacuum bag; forcing a needle on a syringe through the edge of the window laminate in the area of the void; and injecting an adhesive in the syringe into the void to fill the void with the adhesive.
