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.

2 Usage/Applications of PE Coated Aluminum Coil/Sheet

Our company's PE Coated Aluminum Coil/Sheet have been widely used in the fields of construction and decoration(garage doors, ceiling etc.), electronic appliances, lighting decoration, air-condition air pipe, sanwich panels and drainage, etc.

Q:what's the size of aluminum sheet circle?
Aluminum sheet circle’s size is usually the width of coil stock (mm) : 500-1250,800-1400,1000-1600, thickness of coil stock (mm) : 0.4-3.0,1.0-6.0, weight of coil stock (kg) : 8000,10000, diameter of blank(mm) : 85-660,85-750,100-900. Aluminum sheet circle is broadly used in electron, daily chemical industry, medicine, education and car accessories industry. Electrical appliance, thermal insulation, machine manufacturing, cars, spaceflight, military industry, mould, construction, printing and other industries. Kitchenware, such as non-stick pan, pressure cooker, etc. and hardware, such as lampshade, shell of water heater, etc. they are one of the highly processed aluminum products with largest consumption.
Q:Could copper wire be welded with aluminum sheet?
Copper wire could be welded with aluminum sheet, and it needs to use low temperature welding method, if copper wire is in the unit of millimeter and aluminum sheet is also in the unit below 1 mm, you can use electric soldering iron to heat it as hybrid welding and choose low temperature welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. As for the large aluminum sheet, you can take liquefied gas multihole lance as heat source, then choose the same low temperature materials as welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. Welding fundamentals of these two welding methods: both of them are use heatable heat source to heat the matrix to 179 degree, the melting point of WEWELDING M51, then use matrix’s heat conduction to melt welding wire, completing welding. The process of melting welding wire is the process of smearing the welding wire with flux into welding area, melting welding wire completely depends on matrix’s heat conduction.
Q:Could two pieces of aluminum sheets be welded together?
or you can use file to rub back and forth, and it needs lots of practices or you can't weld the sheets.because aluminum sheet cann't be tightly welded to tin, it's hard to weld two pieces of aluminum sheets by common welding's hard, the aluminum sheets are oxidized soon after polished by abrasive paper.and you need to cover the new polished area with soldering paste and learn some operating skills.owing to aluminum sheets' high oxidized speed, you need to wipe the aluminum sheets with soldering paste and soldering tin and rub them with large power soldering iron, then the aluminum sheets will be tightly welded to two pieces of aluminum sheets could be welded together.
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:Could induction heating fuenace be packaged with aluminum foil as insulation material?
You can choose the thermal insulation material according to temperature.
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.
Q:as for heating coil and aluminum sheet, which one is better for heating?
Heating coil has a short lifetime, and aluminum sheet for heating can be used for a long time. Stainless steel heating tube is embedded into aluminum sheet for heating, because the heating coil isn’t exposed, it can be used for a long time.
Q:which is the best bonding method for aluminum sheet and plastic?
smear glue, there is a glue special for the bonding of plastic and steel materials.
Q:How could two pieces of aluminium flakes be welded together?
You can use argon arc welding, connect the positive pole with alternating current,aluminum wire as the welding wire.
Q:does aluminum sheet has a function of magnetism isolating?
copper sheet is better.
