Special adhesive compositions

Special glue compounds are used for temporary connection of aluminum pipes. They do not withstand significant loads, and are used when it is not possible to perform cold welding in production conditions. The two-component adhesive includes an epoxy resin and a steel powder added therein as a filler. Supplier Avlob offers to buy aluminum at a bargain price. The price is the best in this segment of rental.

Sequence of operations

• The epoxy component is kneaded to a pasty state.
• When the resin becomes a high viscosity paste, a solvent is added to it and mixed;
• The finished composition is applied to the jointed joints of aluminum products, which are then tightly pressed against each other;
• After a while, the mixture polymerizes, which can be detected by changing its color. Then the pressure on the joint can be removed, and the design of the pores can be used.

Die-dressing and deformation of deformable aluminum

It is necessary to use special deforming equipment — presses, but the quality of the connection in its mechanical characteristics is not inferior to the original metal, and in some cases exceeds it. Two technological solutions are used:

• Cold stave. Special holes (hollow or solid) of deformable aluminum alloy are inserted into the holes between the parts to be joined. Then the special tools riveted the rivets. As a result, a reliable fastening is formed; The strength of the joint corresponds to the strength of the rivet on the shear:
• Cold disembarkation / sedimentation. Can be used for both flat surfaces and joints. In the first case, protuberances are squeezed out from opposite sides by cone-shaped punches, which are then subjected to draft on hydraulic presses. The place of cold welding is kept under pressure for a few seconds to overcome the plastic inertia of the metal. At the butt-cold welding, the butt ends are placed in matrices with a protrusion of 2… 4 mm, after which they are tightly compressed under the hydraulic press slider. In this case, the joint is further strengthened due to plastic deformation of aluminum.
