Aluminum Color Coated Sheet is Aluminum Sheet with color coated on one side or two sides.It is widely used in construction areas.It is light in the weight and easy to be recycled.Also with the color coating,the surface is good looking and has longer life in corrosion resistance.Aluminum Color Coated Sheet has more advantage as follows:
1. Easy to process. Aluminum Color Coated Sheet Colored Aluminum Sheets,Painted Aluminum Sheets,Decorative Aluminum Sheet,Coloured Aluminium Sheet Trumony Aluminum Limited , https://www.szaluminumpipe.com
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
Fire smoke valve set what are the requirements
Exhaust fire damper is installed in the exhaust pipe system, within a certain period of time to meet the requirements of fire-resistant stability and fire integrity requirements, the role of fire smoke from the valve. Action temperature is generally 280 ℃. A fire, smoke fire damper can be opened automatically or manually smoke, when the flue gas temperature reaches or exceeds 280 ℃, the valve automatically shut down to prevent the spread of fire. Exhaust fans should be guaranteed at 280 ℃ can still work continuously for 30min. Exhaust fire damper setting requirements are: (1) exhaust system exhaust manifold, smoke exhaust valve should be set. (2) Exhaust air duct into the exhaust fan room, should be set fire smoke damper, and exhaust fan linkage. (3) In the exhaust pipe that must pass through the firewall, a smoke damper shall be set up and linked with the exhaust fan.
