High quality capacitor aluminum foil

 

Capacitor aluminum foil is made of high-purity aluminum, which is widely used in capacitors, high voltage transformers and other industries. The thickness of aluminum foil for capacitor is 0.006mm, and the width can be made 500mm, and specific requirements can be customized. 1060 aluminum foil has the characteristics of high plasticity, corrosion resistance, electrical conductivity and thermal conductivity. The 1060 aluminum foil used in electrolytic capacitors is a corrosive material that works under polar conditions, it has higher requirements for the structure of the aluminum foil.

capacitor aluminum foil

The capacitor aluminum foil used is divided into three types: cathode aluminum foil, with a thickness of 0.015mm to 0.06mm; high-voltage aluminum foil, with thickness of 0.065mm-0.1mm, and the aluminum foil is required to be produced with high-purity aluminum; the thickness of the low-pressure aluminum foil is 0.06mm-0.1mm.

 

The basic structure of aluminum electrolytic capacitors includes anode aluminum foil, cathode aluminum foil, electrolyte, aluminum shell, plastic cover and other components. Among them, the anode aluminum foil (ie, corroded into foil) and electrolyte (ie the actual cathode of aluminum electrolytic capacitor) play a major role in the performance of aluminum capacitors. 30%-70% of the cost of aluminum electrolytic capacitors comes from the corrosion formed foil. Electrode aluminum foil is a key basic material for the production of aluminum electrolytic capacitors and is used to carry charges. The performance of the electrode aluminum foil determines the capacity, leakage current, loss, life, reliability, volume and other key technical indicators of aluminum electrolytic capacitors. It is also one of the most valuable and most technically needed parts in the aluminum electrolytic capacitor industry chain.

 

The selection of capacitor aluminum foil determines the performance and quality of aluminum electrolytic capacitors, and the stability and reliability of capacitor quality further determines the quality of the entire electronic product.

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...
