Q:as for heating coil and aluminum sheet, which one is better for heating?
Both of them have advantage. It depends on the new product type it’s applied. Heating coil: it’s applied in some products with high temperature and large heat release, such as oven and other types.
Q:what's the difference between zinc sheet and aluminum sheet?
Only the zinc sheet reacts after adding concentrated nitric acid in drops ,zinc is amphoteric.
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.
Q:how to produce aluminium sheet circle?
As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
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 size of aluminum sheet circle?
General diameter of aluminum sheet circle is 600mm, it at least needs aluminum sheet with a 604mm length and width, retain 2-3mm pressing edge. 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:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
Q:Which kind of glue is best for bonding wood and aluminum sheet together?
cm2, leather. 4, it’s durable and can endure 106 degree high temperature. Shock resistance, medium viscosity, enhancement mode, little smell, shock resistance, inactivated, hard for bonding, adhesives, wood brick. 480, little white sediment, bonding, acidity, 410。 415: filling the gaps, general furniture, high temperatuPlease operate in the environment of above 50 C, you can adjust according to the usage environment, the quick bonding of laminate , timber bonding and other parts,little white sediment, general type: 222286 belong to high solid, moisture content of bonding wood, shock resistance, low density materials, 6-10kg, bonding materials can conduct machining after having been placed for 24 hours: materials bonding. 3, 496, porous texture and humid environment: general type, coating uniformity of glue not over ±0, carpenter joggle. 6, medium viscosity, cyanoacrylate adhesive 401, good heat resistance, high density materials 12-18 kg packaging, Suitable for furniture. 414 (1) Formica, carpenter’s glue,
