Aluminum plain jacketing roll with moisture barrier is not commonly seen in our daily life. It is widely used in oil refinery, power plant and chemical plant. The difference of aluminum plain jacketing roll and the general aluminum coil is that it has great thermal insulation effect.
As we all know, the sudden drop in the temperature will affect the production efficiency. Therefore, in some special industries, the production personnel will use high quality aluminum with polysurlyn moisture barrier to ensure the production efficiency.
The common thickness is 0.1-3.0 mm. The common alloys are 1060, 1050, 3003, 3A21and5052. Its tempers are usually are H14, H24, H16 and H18. The advantage of the polysurlyn aluminum coil is that its adhesion is very high and it does not fall off after the 24-hour immersion test.
At present, there are not so many manufacturers of polysurlyn laminated aluminum coil. Haomei Aluminum is one of the big aluminum coil supplier. Let it tell you how to choose quality aluminum coil with polysurlyn coating:
1. Check the flatness of the aluminum coil. The flatter, the better. The aluminum coils with paper sleeves has better flatness for it undergoes angles bending. The flatness of the aluminum coil with the aluminum sleeve is lower than that of the paper sleeve. There may be some waste generated during unwinding and finishing. However, the manufacturer can receive it.
2. Look at the gloss of the aluminum coil. The thermal insulation aluminum coil with bright surface has a higher quality.
