Composite aluminum foil insulation material heat reflectivity

In recent years, composite aluminum foil insulation materials have become more and more popular in the thermal insulation building materials industry. They are widely used in the insulation of building roofs and external wall insulation. This is mainly because the aluminum foil sheet blocks the excellent performance of heat transfer and is incomparable to other insulation materials.

　　It is understood that the energy loss of housing in China is about 50% of the wall, about 10% of the roof, and about 25% of the doors and windows. Therefore, the insulation building materials are particularly important for the national energy conservation and environmental protection requirements. As early as 2007, the state issued the GB50411-2007 "Building Energy Efficiency Engineering Construction Quality Acceptance Specification", which stipulates that after completion of all construction projects, the building energy conservation must pass the acceptance before allowing the subsequent branch engineering acceptance. The promotion of the concept of environmental protection and energy conservation has promoted the rapid development of China's thermal insulation building materials industry, and composite aluminum foil insulationmaterials have gradually emerged among a wide variety of insulation materials.
　　According to a company specialized in the production of thermal insulation materials, the composite aluminum foil insulation material is made of aluminum foil veneer + polyethylene film + fiber braid + metal coating, laminated by hot melt adhesive, and absorbed by sunlight. Very low rate (only 0.07), with excellent thermal insulation properties, can reflect more than 93% of radiant heat. In general, heat will always run up in the building. When the aluminum foil insulation inside the wall heats up, the aluminum material has a very low thermal emissivity, which can maintain the indoor temperature well. Compared with insulation materials such as vacuum plates and nano-series insulation blankets, aluminum foil composites are most satisfactory for the reflectivity and transmittance of radiation. In addition, the composite aluminum foil insulation material adopts the latest rubber and plastic modification technology in the world. The main raw materials are polyethylene and EPDM rubber, which are PVC-free, safe and reliable. The insulation performance of the insulation is based on ordinary rubber and plastic foam materials. It has been comprehensively upgraded and has become an upgraded product of rubber and plastic foam materials.

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 ...

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,...
