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 material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
Q:what's the oxidation method of positive pole on the surface of aluminum sheet?
Do chemical polishing again, oxidation time is about 40 – 90 minutes, after finishing all of these, you can conduct positive pole oxidation, choose sulfuric acid solution in normal situation, pretreatment is very important in the whole process, take stereo as negative pole, firstly, use the solution mixed of carbonate-bicarbonate and detergent to heat and clean its surface, pretreat the aluminum sheet, dyeing according to requirement after oxidation, then remove the oxide film with oxide film removal solution, place aluminum sheet on the positive pole, finally closing it in the boiling water for about 15 minutes.
Q:what's the size of gap while pressing 6mm aluminum sheet?
unilaterial gap is 0.1-0.15mm, and you can change the gap according to cutting effect.
Q:Which kind of glue can bond two pieces of aluminum sheets?
glass sealant
Q:What are the colors of iron sheet and aluminum sheet?
red, white
Q:whst should I notice while welding aluminum sheet and aluminum block?
two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
Q:what's the difference between zinc sheet and aluminum sheet?
Only zinc sheet can react, zinc is amphoteric.
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.
