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:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:Who knows the ceiling size of aluminum hang-parcel?
General size of aluminum hang-parcel: 100mm、150mm、200mm、250mm, you can order the length according to your actual demands. General color of aluminum hang-parcel: white, black, blue, pearl white, bianco canopus, etc. you can order the color according to your actual demands. General thickness of aluminum hang-parcel: 0.4mm、0.5、0.6、0.7、0.8mm, you can order the thickness according to your actual demands.
Q:how to find 0.6mm waste strake of aluminum sheet?
ask door and window maker for some strake.
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: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?
According to metal reactivity series order table, aluminum has a better metallicity, but it will be passivated soon after contacting concentrated sulfuric acid, and won’t react again. But copper and concentrated sulfuric acid can react continually. So aluminum sheet becomes the positive pole after passivation.
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
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:has aluminum sheet reacted with concentrated sulfuric acid?
it can be regarded as no reaction, concentrated sulfuric acid will make aluminum's surface inactivation,and produce a layer of dense aluminium oxide film which will prevent further reaction.
Q:does aluminum sheet has a function of magnetism isolating?
copper sheet is better.
