- Q:what's the size of gap while pressing 6mm aluminum sheet?
- choose the 8-10% of the thickness for two-sided gaps.
- Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
- It’s possible, there are several problems: 1, workers won’t wipe it thoroughly and fully, so you can wipe it after soaking. 2, the wiping efficiency is low, and we can use ultrasonic to clean it. 3, the water is poisonous and harmful to environment and workers’ health, so you can use water base to clean it, environmental and non-poisonous. Of course, if you really want to change, you can use detergent special for aluminum materials cleaning of our company, Changlvfeng chemical industry company. a, its PH value is 6.8-7.2 and it is totally an neutral liquid. b, good material applicability, detergent invented for aluminum materials. c, good degreasing ability, it has a good degreasing function for various oil contamination in processing and has no effect on material.
- 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:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
- aluminum will react with oxygen, generating dense Al2O3 oxide film on the surface, once the pure aluminum is exposed in air, it will react with air, generating oxide film to protect it.
- 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:why does 10% sulfuric acid not react with aluminum sheet?
- 10% sulfuric acid has a high concentration and will be passivated and formulate a layer of oxide film after reacting with aluminum,and the reaction will stop after seperating sulfuric acid
and aluminum. there is a layer of Al2O3 oxide film on the surface of aluminum, so it's hard for sulfuric acid to break the oxide film and react with aluminum.
- Q:why does aluminum sheet not react with sulfuric acid nut react with hydrochloric acid?
- aluminum reacts with hydrochloric acid,generating aluminium chloride which can dissolve in water. but aluminum reacts with sulfuric acid,
generating aluminum sulfate which can't dissolve in water and will generate aluminum sulfate, a layer of protective film, preventing aluminum from reacting with sulfuric acid, so there is no significant
- 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:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
- 1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought aluminum.you will know their defferences from their definition.
- Q:How to distinguish aluminum sheet from magnesium sheet?
- seperately put aluminum sheet and magnesium sheet into NaOH solution, the one generating bubble is aluminum sheet, because aluminum sheet will react with strong base , generating hydrogen.
