Anti-oxidation insulation aluminum sheet

1. Look at the flatness of the thermal insulation aluminum sheet. The flatter the better, the aluminum roller sleeve that affects the flatness of the aluminum coil: the aluminum coil with the paper sleeve, the bending angle, no scrap, and the flatness is better. The price is slightly higher; the flatness of the aluminum sleeve with the aluminum sleeve is lower than that of the paper sleeve, and some scrap may be generated at the beginning of the unwinding and finishing. The weight of the entire aluminum coil includes the weight of the aluminum sleeve, but the manufacturer can recycle the aluminum sleeve. cylinder.


 
2, look at the gloss of the insulation aluminum coil sheet, the brighter the aluminum coil, the better.
 
3. The aluminum coil may be scratched during transportation and use. The coated insulation aluminum coil can effectively avoid these problems. The coated insulation aluminum sheet is covered during production. The film is a very thin layer, and the thickness is generally About 6 wire, some people will ask if the price of the laminated aluminum coil will be very high. In fact, this is not the case. The price is similar to the uncoated aluminum coil. The film has only a thin layer and the weight is counted in the aluminum coil. .
 
How to maintain the thermal insulation aluminum sheet is not easy to be oxidized and rusted?
 
1. The aluminum sheet is wrapped with plastic cloth, and there is a leak in the workshop and warehouse roof. The insulation aluminum plate should not be placed to ensure the dry environment of the aluminum film.
 
2, is the sealing of the packaging, the general aluminum sheet will be waterproof packaging at the factory, there is a moisture-proof agent inside, so the user is not allowed to damage the packaging method, the packaging is suitable for long-term storage and use. If there are certain conditions, The aluminum sheet to be used is also packaged as such.
