1. Wash the surface of the plate with plenty of clean water;

2. Use a soft cloth soaked with detergent diluted by water to gently wipe the board surface;

3. Rinse the board with plenty of water to wash away the dirt;

4, check the board, for not clean place with detergent focus on cleaning;

5. Rinse the board with clear water until all the detergent is washed away. 　

Note: Do not clean the hot board (when the temperature exceeds 40°C), because the rapid evaporation of water is harmful to the paint on the board!

In particular, please choose the right detergent. A basic principle is: you must choose neutral detergent! Please do not use strong alkaline detergents such as potassium hydroxide, sodium hydroxide or sodium carbonate, strong acidic detergents, abrasive detergents and paint soluble detergents.

The difference between the electrical conductivity of aluminum plate and copper

Aluminum plate and copper are very common things in our daily life, so what's the difference between aluminum plate and copper, and what's the difference in electrical conductivity?

From the physical properties of metal, we can see that the conductivity of aluminum plate is only lower than that of copper, so it is becoming a popular trend in the world that aluminum strip replaces copper strip, which makes the raw materials of electronic products no longer rely solely on copper strip. Aluminum strip is a aluminum coil finished product obtained by rolling aluminum ingots. It can be cut into aluminum strips and strips with required width by slitting machine components according to different purposes and needs, and it is an important raw material in industry. Aluminum strip has many uses, such as aluminum-plastic composite pipe, cable, optical cable, transformer, heater, shutter and so on. The specific uses mainly include: transformer aluminum strip, transformer aluminum foil, aluminum strip for high-frequency welding hollow aluminum strip, aluminum strip for fin radiator, aluminum strip for cable, aluminum strip for stamping, aluminum strip for aluminum edge strip, etc. The main processing equipment of aluminum strip is slitting machine Group, which can be divided into required length and width according to needs. Of course, the equipment for slitting processing is universal, which can be divided into 8 series according to the different alloy elements contained in aluminum strip, but the commonly used series are 1000, 3000, 5000 and 8000 series at present.

According to different annealing states of aluminum strip, it can be divided into fully soft (O state), semi-hard (H24) and fully hard (h18). At present, Z commonly used belongs to the all-soft series, because all-soft is easier to stretch or bend.

Imported aluminum plates are generally superior to domestic aluminum plates in quality and performance. The imported 6061 aluminum plates sold by our company can be used to process parts and components that need good formability and high corrosion resistance but do not require high strength, such as chemical products, food industry devices and storage containers, thin-plate processed parts, deep-drawing or spinning concave vessels, welded parts, heat exchangers, printed boards, nameplates, reflective appliances, etc. Aluminum strip 3003 is mainly used to process parts that require good formability, high corrosion resistance or good weldability, or workpieces that require both these properties and higher strength than 1000 series alloys, such as tanks and tanks for transporting liquids, pressure tanks, storage devices, heat exchangers, chemical equipment, aircraft fuel tanks, oil conduits, reflectors, kitchen equipment, etc.

5052 has good formability, corrosion resistance, candle resistance, fatigue strength and moderate static strength, and is used to manufacture aircraft fuel tanks and oil pipes, as well as sheet metal parts of traffic vehicles and ships, instruments, street lamp brackets and rivets, hardware products, etc.
