Q:why can aluminum sheet after oxide film removal react quicker with hydrochloric acid?
the reason is very simple, the original aluminum sheet has a layer of dense oxide film AI2O3, which has prevented the inner aluminum sheet from reacting with hydrochloric acid. but after oxide film removal,
aluminum sheet will directly contact hydrochloric acid, generating H2.
Q:Which kind of glue is best for bonding aluminum sheets?
Q:what will happen when aluminum sheet is put into copper chloride solution?
the chemical equation of the reaction, 2Al+3CuCl2=2AlCl3+3Cu, the phenomena when aluminum sheet is put into copper chloride solution: there is red solid generating on the surface of aluminum sheet.
Q:Could two pieces of aluminum sheets be welded together?
sure, it does.
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: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:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:which kind of abraser should be used for deburring of aluminum sheet?
as for the polishing of aluminum material, we usually nylon wheel and similar products.
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.
Q:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
