Product Description:

Prepainted Aluminum Sheet for Composite Panel

1.Structure of Prepainted Aluminum Sheet for Composite Panel

Aluminum Sheets are strengthened and cut from raw materials with different alloys, such as AA5005, AA5052, etc. They are easy for processing in different shapes, good in intensity and can be quickly installed. Aluminium Sheets for Energy Saving Curtain Walls are good in energy saving, weather resistance, fire resistance, easy for maintenance and with many colors.

Aluminium Sheets for Energy Saving Curtain Walls are widely used in construction of metal walls, metal ceilings, car decoration, advertizing panels, etc.

Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
Q:what's the oxidation method of positive pole on the surface of aluminum sheet?
Do chemical polishing again, oxidation time is about 40 – 90 minutes, after finishing all of these, you can conduct positive pole oxidation, choose sulfuric acid solution in normal situation, pretreatment is very important in the whole process, take stereo as negative pole, firstly, use the solution mixed of carbonate-bicarbonate and detergent to heat and clean its surface, pretreat the aluminum sheet, dyeing according to requirement after oxidation, then remove the oxide film with oxide film removal solution, place aluminum sheet on the positive pole, finally closing it in the boiling water for about 15 minutes.
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:whst should I notice while welding aluminum sheet and aluminum block?
two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:Who knows the ceiling size of aluminum hang-parcel?
Buckle plate ceiling is the most general ceiling materials, it suits for decorative materials for the ceiling of kitchen and toilet. It has good dampproof, oil contamination resistance , and inflaming retarding feature. And it has elegant appearance and is convenient for transportation and usage. Aluminum buckle plate is square and it’s general size is 300*300,300*600,600*600, it’s thickness generally is 1.2mm.
Q:has aluminum sheet reacted with concentrated sulfuric acid?
it can be regarded as no reaction, concentrated sulfuric acid will make aluminum's surface inactivation,and produce a layer of dense aluminium oxide film which will prevent further reaction.
Q:what's the difference between zinc sheet and aluminum sheet?
Only the zinc sheet reacts after adding concentrated nitric acid in drops ,zinc is amphoteric.
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:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
