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:what's the difference between the knocking voice of aluminum sheet and stainless steel?
The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
Q:what kind of abradant should be used in the deburring of aluminum sheets? How to grind?
we usually use resin grind stone to grind aluminum sheets, Vibration Grinding Mill is also ok.
Q:Which kind of glue can bond hard shell plastic and iron sheet or aluminum sheet?
You can use 502, Alteco and other instant glue to bond plastic and metal, chloroprene rubber adhesive or glass cement are also ok.
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:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:How to clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
you can answer sodium hydroxide solution, dilute acid is useless, aluminum's oxide film is very thick,as for concentration, aluminum will be passivating in concentrated sulfuric acid. if you are high school student,higher concentration is better, you can complete deoxidation by abrasive paper.
Q:Which kind of glue can bond two pieces of aluminum sheets?
glass sealant
Q:How to clean the engine oil and kerosene on the surface of aluminum sheet?
