FAQ of Prepainted Aluminium Coil:
a: Where is your factory?
b:Now which countries do you export your goods?
Now we export to South East Asia,Africa, North America,South America ect.
- Q:how to avoid oxidation of aluminum sheet after wire drawing?
- leave it alone after wire drawing!aluminum sheet will formulate a layer of dense oxide film. So you don't need to worry about it! Don't often polish the aluminum wire, or they will be more and more slimsy, the oxide film is used for avoiding reoxidation.
- Q:why can't aluminum sheet burn after polishing?
- because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.
- Q:what's the size of gap while pressing 6mm aluminum sheet?
- choose the 8-10% of the thickness for two-sided gaps.
- Q:what's the difference between aluminum sheet detergent and central air-condition detergent?
- Central air condition cleaning includes air-cooled condenser cleaning and water-cooling condenser cleaning, if it’s air-cooled condenser cleaning, you can use aluminum sheet detergent.
- Q:why could aluminum pot be repaired by knocking the aluminum sheet into the pot but not being bonded by glue?
- the oxidation rate of aluminum's surface is very quick, so we cann't use the method of tin welding, and the cost of argon arc welding is very high,so aluminum pot's repair usually uses riveting.
aluminum has low hardness and good ductility, so it can be repaired
by tightly knocking, without the bonding of glue.
general glue will decomposed in open fire, if we bond pot by glue, the pot after repair won't be able to endure high temperature.
- Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
- no, but I'm not certain.
- Q:which is the best bonding method for aluminum sheet and plastic?
- smear glue, there is a glue special for the bonding of plastic and steel materials.
- Q:What are the colors of iron sheet and aluminum sheet?
- Q:why intact aluminum sheet stop quicker than pectinate one in the magnetic field?
- while swinging in the magnetic field, intact aluminum sheets will formulate inner eddy current,that is the annular induced current.eddy current will transform the mechanical energy into heat energy, which makes the aluminum sheet stop quickly.but pectinate aluminum sheet can't formulate intact eddy current, so intact aluminum sheet stop quicker than pectinate one.
- Q:What's the standard thickness of aluminum sheet?
- the thickness of tobacco aluminum foil and red wine bottle cap is designed according to customers demands and manufacturer has no stated specification.
