Q:Can aluminum plate resist acid and alkali?
Aluminum is a more active metal, easy to react with the acid and alkali of the outside world. If it is in water for a long time, aluminum will react with acid and alkali substances in water. How to improve the acid and alkali resistance of aluminum alloy?Mainly through the oxidation of aluminum alloy, so that its surface with a layer of oxide film, to prevent the external acid-base substances on aluminum alloy corrosion.In order to reduce the surface hardness and wear resistance of aluminum alloy and prolong its service life, the surface oxidation surface treatment technology has become an indispensable part of the use of aluminum alloy.
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:Can aluminum plates be welded with stainless steel or iron nuts?
If the thickness of the sheet is not enough, the effective thread stroke can be mounted with K nuts. Rivet nuts are required if accuracy is required.If it is a thick aluminum sheet, it can be directly drilled and tapped; also, the steel screw sleeve can be added.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:What kind of paint would you like to paint on the aluminum plate?
Paint on the aluminum plate should be painted nitrocellulose or polyester paint.Is the aluminum plate with a thickness of more than 0.2mm to 500mm, 200mm width, length less than 16m aluminum material called aluminum plate or aluminum sheet, aluminum is below 0.2mm, 200mm within the width of the row material or bar (of course, with the progress of the large equipment, the width can be 600mm row material also more). Aluminum sheet refers to the rectangular plate made of aluminium ingot rolled and divided into pure aluminum plate, alloy aluminum plate, thin aluminum plate, middle thick aluminum plate and pattern aluminum plate.Nitrocellulose lacquer is a common paint for woodwork and decoration. The main film forming material is mainly to nitrocellulose lacquer, with alkyd resin, rosin modified resin, acrylic resin, amino resin and other resin composed of hard and soft.Polyester paint, also called unsaturated polyester paint, is a kind of multi component paint, it is a kind of thick paint made of polyester resin as the main film forming material. Polyester paint film fullness, thick hard surface. Polyester paint also has varnish varieties, called polyester varnish. Polyester paint needs to be solidified during construction, and the proportion of these curing agents takes up 1/3 of the total paint. These curing agents, also known as curing agents, are mainly composed of TDI (toluene diisocyanate, /toluenediisocyanate). These free TDI will turn yellow, not only to make furniture paint yellow, but also will make the adjacent wall yellow, this is a major shortcoming of polyester paint.
Q:Which kind of glue is best for bonding wood and aluminum sheet together?
cm2, leather. 4, it’s durable and can endure 106 degree high temperature. Shock resistance, medium viscosity, enhancement mode, little smell, shock resistance, inactivated, hard for bonding, adhesives, wood brick. 480, little white sediment, bonding, acidity, 410。 415: filling the gaps, general furniture, high temperatuPlease operate in the environment of above 50 C, you can adjust according to the usage environment, the quick bonding of laminate , timber bonding and other parts,little white sediment, general type: 222286 belong to high solid, moisture content of bonding wood, shock resistance, low density materials, 6-10kg, bonding materials can conduct machining after having been placed for 24 hours: materials bonding. 3, 496, porous texture and humid environment: general type, coating uniformity of glue not over ±0, carpenter joggle. 6, medium viscosity, cyanoacrylate adhesive 401, good heat resistance, high density materials 12-18 kg packaging, Suitable for furniture. 414 (1) Formica, carpenter’s glue,
Q:what's the difference between zinc sheet and aluminum sheet?
Only zinc sheet can react, zinc is amphoteric.
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.
Q:What advantages does the ceramic panel curtain wall have compared with the aluminum sheet and stone curtain wall?
The color of aluminum sheet is single, the quality is not high; the price of stone is high; the color difference is serious; the radiation is not environmental; and the resource is limited; the supply is difficult to guarantee; the weight of the tile is light; the radiation is zero; the pollution resistance is strong. Rich in color, especially in the production process, forms of diversification, to meet high, medium and low-end customer base needs. Zhejiang ruigao company is China and Asia's first introduction of the ceramic plate production line, their R & D capability is recognized. The pursuit of perfection, the introduction of new ideas, and the concept of customization for architects to realize their dreams and fashion designs for the architecture have opened wider space for the wide application of ceramic panels and curtain walls. In fact, the application of ceramic is not limited to curtain wall, but also applied to the lighting effect display, interior decoration and so on. Hi! In short, there are any problems can be exchanged with each other.
Q:The difference between aluminum plate and aluminum plate
Aluminum plate is a large piece, the regular width is 90 to 130 centimeters. The aluminum plate is cut aluminum plate, usually according to requirements made several centimeters wide.
