Q:Spacing of stiffener
As to the stiffener of the aluminum veneer, what are the following points?:1, aluminum reinforcement spacing is generally around 600mm, in order to ensure the aluminum plate in the positive and negative pressure conditions within the scope of deformation. When aluminum plate is welded, there is internal stress due to welding deformation (this internal stress can not be completely eliminated for a long time), and the rigidity of reinforcing bar should also be increased.2. The sectional dimension and spacing of stiffeners shall be determined according to the calculated wind pressure of the aluminum plate. But it is worth noting that the reinforcement calculation of single aluminum plate strengthening is different from the glass curtain wall, first, its strength is certainly no problem (still not seen the wind blowing broken plate, there is no joke) deflection possibility, bend off and windy weather also very few people to pay attention to the single aluminum plate plate surface after deformation the scenery. Therefore, the calculation of deflection of stiffeners are considered under the condition of wind strength and deflection when the winds of aluminum can cause permanent plastic deformation.In fact, aluminum veneer manufacturers generally use the single aluminum plate edge folding groove made of aluminum and 20*40*20, installed in the distance about 600mm. Also useful for profile (grooved aluminum) stiffenersThe spacing between stiffeners is very important to the cost of production. Generally speaking, the spacing of stiffeners will be changed from 600 to 350, and the cost will be increased by 8~15 yuan / square meter
Q:What does 3003-O aluminum mean?
There are four basic states of aluminum alloys:F--Free the condition of a product after a normal working procedure requires no special heat treatment or hardening, and the mechanical properties are not limited.
Q:How do aluminum plates paint?
Pretreatment is usually required. Acid and alkali cleaning can be done either by oil or by xylene,The paintings do not know, but most of them are painted or printed on the aluminum plate, usually by heat transfer, silk screen, or decorative board, which is sprayed directly and then painted.
Q:How to polish aluminum sheet to be bright?
you must do some protection work, or you will fail once aluminum contacts air. Aluminum sheet is easy to be oxided and volatilized.
Q:is aluminum foil spacer poisonous after heating?
It’s a kind of thermoprint material made by pressing the aluminum into sheet, and owing to its similar thermoprint effect to silver foil, so it’s called fake silver foil. Aluminum has soft texture, good ductility, and is silver white, if we use sodium silicate to paste the sheet after pressing on the offset paper, making aluminum foil, the foil can be printed. But aluminum foil is easy to be oxidized and darkens, rubbing and touching will make it darken, so it doesn’t suit for the thermoprint of books’ cover that needs to be preserved for a long time.
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.
Q:How do you calculate the price and weight of aluminum sheet?
Aluminum prices this year. The best SWA seems to nearly 500 square meters.In more detail, you'll have to ask the supplier
Q:How do aluminum plates open holes?
The opening of the aluminum plate is a relatively simple process,You can do that with a micro electric device like an electric drill or a grooving machine
Q:What is aluminum curtain wall.
In the closing means: aluminum curtain wall aluminum panel curtain wall mounted to the side plate finally called closing!On the aluminum ceiling installation knowledge and aluminum product knowledge welcome Baidu Guangzhou "China Hainan" brand aluminum ceiling understanding
Q:Computer cooling aluminum plate, what specific materials used? 30
Copper heat conductivity is good, but the price is more expensive, difficult to process, the weight is too large (a lot of pure copper radiator is beyond the limit of CPU), the heat capacity is small, and easily oxidized. The pure aluminum is too soft, can not directly use, are the use of aluminum alloy to supply enough hardness, aluminum alloy is the advantage of low prices, light weight, but the heat conductivity is much worse than copper. Some of the radiator embedded in a copper plate in each in his element, Aluminum Alloy radiator base.
