PE(polyester) Coating

PE(polyester) coating:high molecular polymer as monomer and addition of alkyd, is an UV-resistant coating. It can be classified matt and glossy according to coating gloss. The compact molecule structure, makes paint surface luster and smooth,which assure good printing on the panel surface. With an warranty of 8-10 years for weather resistance, it is specially applied for internal decoration and sign board.

Q:why can aluminum sheet after oxide film removal react quicker with hydrochloric acid?
the reason is very simple, the original aluminum sheet has a layer of dense oxide film AI2O3, which has prevented the inner aluminum sheet from reacting with hydrochloric acid. but after oxide film removal, aluminum sheet will directly contact hydrochloric acid, generating H2.
Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding usually overlays two pieces together and presses them, heating them to melting state through current, you can try multiple sheets.
Q:Which kind of glue can bond hard shell plastic and iron sheet or aluminum sheet?
You can buy the glue for bonding wood in hardware shop, 402 or 502 are all ok.
Q:How to polish aluminum sheet to be bright?
you must do some protection work, or you will fail once aluminum contacts air. Aluminum sheet is easy to be oxided and volatilized.
Q:does aluminum sheet has a function of magnetism isolating?
no, it needs ferromagnetic materials.
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:is there aluminum oxide on the surface of aluminum sheet after being polished by abrasive paper?
aluminum will be oxided as aluminum oxide once being exposed in air.
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:what's the difference between zinc sheet and aluminum sheet?
Only zinc sheet can react, zinc is amphoteric.
Q:how to find 0.6mm waste strake of aluminum sheet?
ask door and window maker for some strake.
