- Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
- physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
- Q:what's the difference between aluminum sheet detergent and central air-condition detergent?
- Central air condition cleaning includes air-cooled condenser cleaning and water-cooling condenser cleaning, if it’s air-cooled condenser cleaning, you can use aluminum sheet detergent.
- 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 material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
- Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
- 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: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:which kind of enterprises are aluminium sheet circles used in?
- user use cold squezz method to transform the aluminum sheet circle into various standard capacitor shell, aluminium collapsible tube shell, which are broadly used in electron industry, daily chemical industry, medicine, education and automobile products,electrical appliance, heat preservation, machine manufacturing, automobile,spaceflight,military industry,mould, construction, printing and other industries.
- 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:what’s the difference of activated aluminum and aluminum sheet?
- 39,the thermal treatment of age hardening aluminum alloy, 40, lanthanum-praseodymium-cerium aluminum alloy and its producing technology, 41,casting method of cool room pack alloy without draft angle, 42, use the anti-corrosion alloy layer to protect the surface of nickel base alloy products, 43,saltless and inoxidizability remelting method of aluminum, aluminum alloy and aluminum waste...
