Performance index of aluminum foil

Aluminium foil is a kind of coil, strip or sheet product with thin thickness after rolling of aluminium alloy. In general, we call the Aluminum Alloy which thickness is less than 0.2 mm as aluminum foil. The properties of aluminum foil are thin and light-weight, high strength, good gloss, high thermal conductivity and electrical conductivity, high moisture resistance, non-toxic, tasteless, good cover rotation, heat insulation, good corrosion resistance. So what is the performance index of aluminum foil? Here we can give you the answer!
aluminum foil

Tensile strength: refers to the maximum stress value of material before breaking. At present, the most common method to measure tensile strength in China is using the universal material testing machine to measure the tensile and compressive strength of materials. Elongation rate: the percentage of total elongation and original gauge length after tensile fracture. Yield strength: the critical stress value of material yielding. Cupping: refers to the process stamping performance of products. In aluminum foil factory testing, the tensile strength and elongation of the product are the data test most, and the cupping value is generally used for performance testing of aluminum foil products for deep drawing, such as air conditioning heat sink aluminum foil, aluminum foil food container and so on.

Differences between PS and CTP base plate

图片
With the increasing maturity and the rapid development of CTP technology, as well as the declining of price, CTP technology has been more and more welcomed by the majority of printing practitioners, usage of CTP plates have the potential trend to catch up with the traditional PS plate. The overall requirements of the printing plate is very high, especially the current CTP plate is mostly used for high-grade color printing plate, to ensure the quality of the plate, the plate based apparent quality is the premise. The characteristic of CTP technology is the quality of CTP based plate, such as the apparent quality, physical property and electrolytic performance. The aluminum plate base is widely used according to CTP plate technical requirement. The difference between CTP plates and PS plate on the apparent properties of aluminum plate base are as follows. The basic appearance requirements of the aluminum base plate is clean and smooth, no cracks, corrosion pits, air vents, scratches,...

Introduction of aluminum foil insulation material

图片
Aluminum foil insulation material is the best thermal insulation material at present in the world. It has the advantages of light weight, low thermal conductivity, good heat resistance, aging resistance, easy combustion with other substrates, bonding does not produce droplet and other excellent properties. On the application, it is widely used in building roofing, wall, ceiling, floor, doors and windows as insulation materials. Aluminum foil itself is a good conductor of heat, directly used basically has no heat insulation, but accelerate the heat loss, so when used the insulation cotton is wrapped inside the aluminum foil . It has the functions of heat insulation, waterproof, moisture-proof and so on. Its solar radiation absorption coefficient is very low, which can insulate most of the heat transfer. Introduction of advantages of aluminum foil insulation material: (1) Simplification of structure to avoid waste. (2) It is unnecessary to set roof exhaust system. (3) Waterproof lay...
