Q:Which kind of glue is best for bonding aluminum sheets?
I advice you to use AB glue to bond aluminum sheets, acylic acid AB glue is better than 502 in bonding aluminum sheets, Gelianghao XSSS-290AB glue sold in hardware store can directly permeate into the surface of aluminum sheets and bond the sheets tightly.
Q:What is the use of the aluminum tape?
Taking aluminum foil as the base material and then coated with acrylic adhesive, aluminum tape is featured by high peel strength, excellent adhesion and oxidation resistance, corrosion resistance and flame resistance. Aluminum foil can be classified as common aluminum tape, conductive aluminum tape, high peel strength aluminum tape, reinforced aluminum tape, clip marine welding aluminum tape, aluminum tape for heater, etc., so the effects are different. For example, the commonly used aluminum tape is mainly used for binding cold (hot) gas pipeline in cold (warm) gas engineering and water heater manufacturing. Conductive aluminum tape is commonly used for eliminating electromagnetic interference (EMI), isolating electromagnetic wave to human body harm and avoiding unnecessary voltage or current that may influence its function in all kinds of transformers, mobile phone, computer, PDA, PDP, LCD displays, notebook computers, copiers and other electronic products in which electromagnetic shielding is required. electromagnetic shielding. Conductive aluminum foil has several types, like double-sided conductive aluminum foil and single-sided conductive aluminum foil. .
Q:What's the function of aluminum foil
It can be used to wrap the food to cook(by pot), like barbeque.
Q:What's the difference between singled-sided conductive aluminum tape and double-sided conductive aluminum tape?
Differences: a) Installation: The heating element of singled-sided conductive aluminum tape is single-stranded solid wire. When installing, the heating element should be connected with temperature controller or other distribution equipment before the heating cable is laid into a loop; Since the heating element of double-sided conductive aluminum tape is double-stranded solid wire, the heating cable itself serves as a loop. Thus double-sided conductive aluminum tape is easier to install.
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
Q:The dark face of 8021 aluminum foil appears uneven rolling. What causes this and how to solve it?
The uneven rolling that you have mentioned is scratch or silvering. If it is scrath, this scrath may ba caused during the rolling process or the oil surface is scratched during the process of oil cleaning cut (finishing mill is single open book); Double open book in the process of finishing mill may also have a very small probability to cause rubbing scratch. If it is uneven rolling, it may be caused during the rolling process or the oil level exists silvering in the process of oiling(finishing mill is single open book). Seeing if it is cyclical since silvering is cyclical
Q:What are the effects of casting temperature on ductility of aluminum coil?
The tensile strength and ductility increase with the solid solution insulation time, and reach best fit at 1 hour. Continue thermal insulation, and the tensile strength will change little while the ductility will reduce. This is because the solid solution over insulation will cause the work pieces crystallize so that the large crystal reduce the plasticity.
Q:Can I use dyne pen to test the wetting tension in the appearance of aluminum foil? What's the standard?
What kind of dyne pen imported from America enjoy the highest cost performance? The method can accurately measure the surface tension of the base material, surface wet strength and determine the surface factors of base material. Relative humidity should not exceed the standard since high humidity is easy to aggravate the variability of data.
Q:What’s the use of aluminum foil glass wool felt ?
Glass cotton has good sound insulation, usually called sound insulation cotton. Aluminum foil composite glass cotton felt has passed the anti-aging experiment, with durable years as long as 30 years. And its sound insulation, anti-condensation, and tensile strength can be greatly improved so that it can not only insulate sound but also absorb them.
Q:Is tin foil paper the same as aluminum foil paper?
Tin foil paper is a kind of film-shaped metal paper stuck with silver: Metal paper for packing cigarette is often silver-white. Aluminum foil paper is made by sticking aluminum foil backing paper with aluminum foil pasting paper to serve as moisture-proof and decorating packaging material for good cigarette and candies. There isn’t much difference between tin foil paper and aluminum foil paper, both of which can be used to cook and pack food.
