Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
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 aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:who knows the ceiling technology of aluminum sheet?
Different materials usually have difference in construction technology. The detailed ceiling construction technology process of aluminum buckle plate:1, snapping line: according to the elevation horizontal line of floor, designed elevation, surrounding ceiling elevation horizontal line, you can find the central point of your room. Then alone the ceiling’s elevation horizontal line, take the central point of your room as focus, you can draw the grading line of keel. 2, install main keel boom: after ensuring the ceiling’s elevation horizontal line and keel’s location line, you can measure the elevation of the below ending of boom, and install the boom processed before. You can use expansion bolt to fix the boom on ceiling. Choose round steel as boom, control the gap of hanging bar under the range of 1200mm.3, install main keel: choose C38 light steel keel as main keel, control the gap under 1200mm. connect it with fitting and boom matched with main keel while installing. 4, install side keel: fix 25×25mm coated keel on the surrounding wall with cement nail according to net height of ceiling, control the cement nail’s gap under 300mm. 5, install sub keel: install the sub keel matched with aluminum buckle plate according to the size of aluminum buckle plate, hang the sub keel on main keel through hanger. When the sub keel needs to be prolonged by several keel, use the adapting piece of sub keel, connect the two ends and fix them after straightening at the same time of hanging the sub keel.
Q:what’s the difference of activated aluminum and aluminum sheet?
you can use weak acid ,weak base solvent or steam to clean the oil and dirt on the surface, it's activated aluminum, their difference is that activated aluminum has porous structure oxide film.
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: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: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: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:how to make aluminum products bright? How to polish or clean the products punch formed by 0.3mm aluminum sheet?
you can try to grind it with magnetic grinder.
