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.
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 kind of abradant should be used in the deburring of aluminum sheets? How to grind?
you can use deburring brush,grinding fluid,abrasive powder and other consumables.
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:could magnet attract iron with the seperation of rubber and aluminum sheets?
It does in theory, but rubber and aluminum sheets can’t be too thick, larger magnetic force of magnet will be better.
Q:after putting aluminum sheet into the area between magnet and iron products, could magnet attract iron again?
magnet can attract iron if the aluminum sheet isn't too thick. Because aluminum can't cut off magnetic line of force, unless aluminum sheet's thickness surpass the range of magnetic attraction.
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:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
It’s possible, there are several problems: 1, workers won’t wipe it thoroughly and fully, so you can wipe it after soaking. 2, the wiping efficiency is low, and we can use ultrasonic to clean it. 3, the water is poisonous and harmful to environment and workers’ health, so you can use water base to clean it, environmental and non-poisonous. Of course, if you really want to change, you can use detergent special for aluminum materials cleaning of our company, Changlvfeng chemical industry company. a, its PH value is 6.8-7.2 and it is totally an neutral liquid. b, good material applicability, detergent invented for aluminum materials. c, good degreasing ability, it has a good degreasing function for various oil contamination in processing and has no effect on material.
Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
it may be that aluminum won't react with concentrated nitric acid.
Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
it firstly etches off the oxide on the surface of aluminum, and then reacts with aluminum, generating bubble.
