Aluminum Honeycomb Composite Panel Thermal Conductivity

Aluminum honeycomb panel is suitable for construction of civil buildings, vehicles and vessels etc. It was originally a specialized aircraft material. Therefore, it must meet strict technical data. Aluminum honeycomb panel thermal conductivity is 0.88w/m.k. Its density is between 3.6 and 5.3kg/m2, and tensile strength more than 83MN/m2. The manufacturing of the aluminum honeycomb composite panel is carried out by advanced modern machines that adopts hot molding technology. Owing to high thermal conductivity between the aluminum sheet and the honeycomb body, the thermal expansion and cold contraction of the inner and outer aluminum skins are synchronized. The aluminum covering sheet has small holes to allow the gas inside the panel to flow freely. The panel has a sliding mounting buckle system which does not deform in either thermal expansion or cold contraction.

　　Aluminum honeycomb panels are mainly made of high quality 3003H24 alloy aluminum plate or 5052AH14 high manganese alloy aluminum plate as the base material. The thickness of the panel ranges from 0.8mm to 1.5mm. The panels can be divided into two types by surface treatments: fluorocarbon roll coated panels or color resistant paint panels. The color resistant paint is resistant to scratches, acid rain and corrosion. It has a self-cleaning ability stronger than PVDF. The thickness of the bottom plate is from 0.6mm to 1.0mm, and the total thickness of the panel is around 25mm.
　　Due to the fact that the aluminum honeycomb panel has excellent performance against high wind pressure, shock absorption, sound insulation, heat preservation (high thermal conductivity inside the panel), flame retardancy and high specific strength, it had been used in various fields abroad in the 1960s. In China, however, honeycomb technology was not applied until its rapid development overseas. A piece of aluminum honeycomb composite panel weighs only 1/5 of the aluminum veneer with the same stiffness and 1/10 of the steel plate. The interconnected aluminum honeycomb core is like a myriad of I-beams. The core layer is fixed in the whole plate to make the plate more stable. Its wind pressure resistance is much superior to aluminum slabs and aluminum veneers, and has the characteristics of good flatness which will not be easily deformed in spite of large cell sizes. All these advantages make it the preferred lightweight material for the construction industry.

Slitting of 1mm 2mm 4mm aluminium strip

图片
What kind of machine is used to make aluminum sheets into 1mm 2mm 4mm aluminium strip belts? Many people might think about a shearing device, but they are actually dealt with by a continuous slitting unit of a similar working principle to that of a shearing device. The difference lies in the point that there is no pause of shearing with a continuous slitting unit. Generally, the mother roll, namely, an  aluminum coil  to be slit, is placed. During the slitting process, the coil roll is divided into several belts which are further rolled into narrow aluminium strip rolls. The slitting method of both  1mm 2mm 4mm aluminium strip  or other aluminum strips can be divided into two types: a straight pull type and a loose sleeve type. The straight pull type refers to the method that aluminum strip rolls are kept in tension from being fed into the unwinding sail to being coiled by the coiling machine, and this production method is suitable for trimming and intermediate ...

Diamond Embossed Aluminum Sheet Application

The  diamond embossed aluminum sheet  refers to aluminium sheets with diamond patterns on the surface. In addition to 1000 series, 5005 and 3003 are frequently applied alloys as well. 5005  diamond embossed aluminum sheet s can be used for conductivity materials, cookware, instrument panels, electronic shells and building ornaments. Their anodized film proves to be brighter than that of 3003, and the color matches perfectly with that of 6063 aluminum alloy products. Generally speaking,  diamond aluminum checker plate s are sold by the unit of pieces. In international business the unit of metric ton is frequently used as well. Their thickness ranges from 1.7mm to 8mm, but those between 2mm and 7.75mm prove to be the most popular. The width is from 1010 to 1500, among which 1250 and 1500 are most frequently adopted. Embossed aluminum sheet s with different patterns usually match varied application scope. Five-bar and one-bar sheets are mostly used for anti-skid pu...

Embossed Aluminium Coil Patterns And Applications

图片
If you have ever used an escalator you might have noticed that there are partition panels respectively at the bottom and top of the escalator. These partitions are usually paved with  embossed aluminium sheet  coil that have a good pressure bearing capacity and are made of composite metals. As a matter of fact, there are various patterns and applications of embossed aluminium coil, and here we will give a simple introduction. 　　Patterns 　　Aluminum sheets with patterns on the surface is called embossed aluminum sheets or  aluminium tread plate . Pattern shapes include lentils, diamonds, round beans, and oblate mixed shapes. The market is most common in lentils. 　　Application 　　The aluminium tread plate has beautiful appearance, excellent anti-slip property, enhanced performances, and material-saving advantage in production. It is widely used in transportation, construction, decoration, equipment, floor, machinery, shipbuilding and other fields. Generally speaking,...
