Honeycomb aluminum foil, also known as aluminum honeycomb core, is a type of lightweight core material made from two layers of aluminum foil that are bonded together in a way that creates a series of hexagonal cells, much like a honeycomb.
Honeycomb aluminum foil, also known as aluminum honeycomb core, is a type of lightweight core material made from two layers of aluminum foil that are bonded together in a way that creates a series of hexagonal cells, much like a honeycomb. These cells are then expanded into a core material that is lightweight, strong, and rigid.
Honeycomb aluminum foil is commonly used in a variety of applications, such as aerospace and aviation industries, marine and naval structures, as well as in construction and architecture. The lightweight and high strength properties of honeycomb aluminum make it an ideal material for sandwich panels, which are made by bonding two outer layers of material (such as fiberglass or carbon fiber) to a honeycomb aluminum core.
Honeycomb aluminum foil also has excellent sound and vibration dampening properties, making it useful in applications such as speaker grills, acoustic panels, and industrial enclosures.
Executable standards for honeycomb aluminum foil: national standard, American standard, European standard, Russian standard, Chinese standard, etc.
|Width||20-1500mm, Common 914/1020mm, max 1500mm|
|Honeycomb side length||5/6/8/10/12 mm|
|Surface technology||Pickling+water washing+silane passivation+epoxy varnish|
Aluminum foil for honeycomb core is a type of aluminum foil that is used as a raw material to manufacture honeycomb cores.
The common alloy grades are 3003/3004/3104/5052, the mechanical and mechanical properties of 3004 and 3104 are basically the same, usually 3004 can be used instead of 3104 alloy aluminum;
The biggest difference between honeycomb core used aluminum foil and conventional aluminum foil is the surface treatment;
1. High board surface flatness – good board shape
Equipped with a shape controller to monitor the shape in real time; the follow-up straightening process, the second correction of the shape; to ensure that the aluminum foil shape is good, the layout is high, and the shape accuracy is good!
2. High strength – not easy to deform after processing
3003-h18 aluminum foil is used as the aluminum foil base material for the honeycomb core, which has high strength, the finished product is not easy to deform, the end surface is flat, the edge is free of burrs, and the board surface is flat after bonding and laminating;
3. The surface of the aluminum foil is degreased and clean – the glue is not easy to fall off
Special degreasing equipment and passivation process ensure that the surface of the aluminum foil is free of oil, the adhesive is firm, not easy to fall off, and has a long service life;
The upper and lower bottom plates and panels of aluminum honeycomb panels are made of aluminum alloy plates, with a thick and light honeycomb core sandwiched in the middle (the aluminum honeycomb core is made of aluminum foil through complicated processes;), the panel and the sandwich core are bonded The agent is cemented into a monolithic rigid structure.
Panel surface treatment can be fluorocarbon, roller coating, thermal transfer printing, wire drawing, oxidation; aluminum honeycomb panels can also be pasted and compounded with fireproof boards, stone materials, and ceramics.
Aluminum honeycomb panels have the characteristics of light weight, high strength, sound insulation, heat insulation, waterproof, moisture-proof, and heat preservation;
Derived from dyne, it is the unit of force, expressed as dyne/cm, expressing the size of the surface tension coefficient, defined as the force of mutual traction per unit length between two adjacent parts of the liquid surface, 1dyn/cm=1mN /m.
When the surface tension coefficient is large, the liquid can wet the solid surface better, that is, the surface dyne value of the material is high.
The wettability of solid surfaces is usually evaluated by surface free energy, contact angle, and dyne value. Relatively speaking, the contact angle measuring instrument will be more accurate, followed by the surface free energy, and the dyne pen can quickly and roughly judge.
Dyne Pen Test
Dyne pen specifications generally range from 30-70, and our common ones are 36/38/40/42/44. These numbers represent that the surface tension coefficient of the material is so large
How to use Dyne pen:
Choose a pen with an estimated dyne size.
Draw a straight line (5-10cm) evenly on the surface of the measured object with the Dyne pen.
After 2~3 seconds, observe whether the handwriting shrinks and condenses into water droplets. If there are shrinkage drops, change to a dyne pen with a lower value and draw a straight line until there is no shrinkage and no droplet points to determine the surface tension value of the object.
If the handwriting is smooth, change to a dyne pen with a higher value and draw again until the handwriting shrinks, then the dyne pen number of the previous value is the dyne value on the surface of the measured object.
Dyne pen result analysis:
If the drawn lines are evenly distributed without any beads, it means that the surface tension of the film is higher than the dyne pen index, and it can be printed in this case.
If the drawn line shrinks slowly, it means that the surface tension of the film is slightly lower than the dyne pen index. In this case, the printing effect is not good.
If the drawn line shrinks immediately and forms bead points, it means that the surface tension of the film is very lower than the dyne pen index. This case cannot be printed.
Cable aluminum foil, also known as aluminum foil for cable, refers to a specific type of aluminum foil that is used in the manufacturing of cables and wires.
