Q:How to clean the engine oil and kerosene on the surface of aluminum sheet?
You can clean it with detergent of carburetor, and buy it in auto accessories shop.
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:The advantages and disadvantages of waterproof aluminum film and aluminum foil
me for use shorten to five years. it is influenced by the environment and quality.5.if the same roll takes this method of coverage, the combination property is nearly the same.
Q:What is the principle of thermal insulated aluminum tape?
The principle of thermal insulated aluminum tape is to process various metals like aluminum, gold, copper and silver into multi-layer densely and highly thermal-insulated metal film by utilizing vacuum metallization and magnetron sputtering. When the outer-shell electron (free electron) in the metal material which is generally not bound by atomic nucleus is exposed to light waves, the electric field allows it to absorb the light energy and thus produces vibration at the same frequency as light. Then the vibration produces the light at the same frequency as the original light, which is known as the reflection of light. The higher perveance of metal, the lower degree of penetration and the higher reflection. The metal layers will reflect back the heat source in the sun including infrared ray, ultraviolet ray and visible light selectionally and then re-release after the colors of metal film absorb the solar radiation and finally part of heat can be removed as the outdoor air flows, thus effectively insulating the heat.
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:What’s the production standard of aluminum coil?
GB/T3880-2006 mechanical standard GB/T3190-1996 chemical standard
Q:How to tear the aluminium paper package neatly by handy techniques
Use the rule to press the tin paper and use box cutter to cut the paper in right size.
Q:How can aluminum foil classification?
First, according to the thickness Differences can be divided according to the thickness of aluminum foil thick foil, single zero foil and double zero foil. 1. Foil thickness: 0.1 ~ 0.2mm thick foil. 2. The single zero foil: thickness of 0.01mm and less than 0.1mm / foil. 3. The double zero foil: a so-called double zero foil after its thickness is in mm unit of measure of the decimal point two zero foil, usually aluminum foil of a thickness of less than 0.01, namely 0.005 ~ 0.009mm aluminum foil.
Q:What are the characteristics of color coated aluminum coil?
4. Mechanical: High quality aluminum, plastics and adhesives, the use of advanced composite technology. Products with the desired decorative plate bending, bending strength at the four seasons climate state, change air pressure, temperature, humidity and other factors, will not cause bending, deformation, expansion or the like.
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 phenomena.
