- Q:Why the aluminum-plastic panel processed by color aluminum coil peel off paint?
- It may be due to the bad quality of the color aluminum coil paint or the poor paint-drying process.
- Q:What are the effects of casting temperature on ductility of aluminum coil?
- The tensile strength and ductility increase with the solid solution insulation time, and reach best fit at 1 hour. Continue thermal insulation, and the tensile strength will change little while the ductility will reduce. This is because the solid solution over insulation will cause the work pieces crystallize so that the large crystal reduce the plasticity.
- Q:How to deal with too much aluminum powder in aluminum striping?
- Currently, there are bag dust-removal system and water dust-removal system. The former is very popular with enterprises because of low maintenance cost, accounting for over 90%. But the problem is the dust accumulation because the ventilation and dust removal systems are not produced in strict accordance with the standard. For example, controlling wind speed does not meet the requirement; ventilation and dust removal system does not meet the requirements of explosion-proof, including the set of pipes, series and parallel connection, the choice of dust removal system, the spark detection and extinguishing measures.
- Q:If the aluminum coil is 220 kg, 0.3 thick and 500 wide, how much is the coil diameter?
- With the outer diameter and inner diameter, you can know the volume. With the density and volume, we can calculate the weight. And with weight, we can know the length.
- Q:What is the common color of aluminum coil membrane?
- The blue transparent membrane is the most common.
- Q:What should pay attention to transporting aluminum coil?
- You must ensure the good property of the aluminum coil.
- Q:What do the two items (COIL:873347 HEAT: number) on the label of the raw material of aluminum coil stand for?
- COIL means aluminum coil and HEAT means heating, so together they mean hot rolled coil.
- Q:Why the aluminum sheet crack after?
- It is either because of wrong filling material for welding or bad welding quality. It doesn’t crack after welding, but cracks when the increasing tension in circling process exceeds the internal stress of the weld.
- Q:Why does the end face of aluminum coil have grease spots?
- Process one without coolant to see whether there are spots. There is a layer of alumina membrane on the blank face of aluminum coil, which will react with basic coolant when heating through processing.
- Q:What is the formula to calculate the wall thickness of aluminum coil?
- Aluminum coil thickness*aluminum coil width*aluminum coil curl*aluminum density (the density of aluminum alloy: 2.73, the density of pure aluminum: 2.71)
